Another Downside of Supplemental Insulin

Friday, March 19, 2010 by Dr. Julian Whitaker
In my earlier post, I explained that supplemental insulin can cause people who are trying to manage diabetes to gain weight.  Sadly enough, weight gain isn’t the only downside of insulin use.

Another strike against insulin is its tendency to increase your risk of hypertension.

Taiwanese researchers looked at more than 87,000 patients with type 2 diabetes who were treated with either oral drugs or insulin. They found that patients managing diabetes using insulin had a higher prevalence of hypertension (61.3 versus 53.9 percent), and the longer they used it, the greater their risk.

This is not surprising when you consider insulin’s activities beyond nutrient storage.

Injected insulin increases sodium retention and stimulates the sympathetic nervous system. It induces oxidative stress, leading to free-radical damage that impairs the function of the endothelial cells lining the arteries. It also has growth factor–like activity that thickens blood vessels and increases risk of atherosclerosis, which also adversely affects blood pressure health.

Since people living with diabetes are already at dramatically increased risk of hypertension and cardiovascular disease, the last thing they need is a treatment that amplifies this risk.

I opt for more natural remedies for diabetes, many of which I’ll be discussing here in my blog. Please stay tuned.

The Downside of Supplemental Insulin

Wednesday, March 17, 2010 by Dr. Julian Whitaker
Although most people think injected insulin is reserved for type 1 diabetes, more than one in four people also use insulin to treat type 2 diabetes. And, in most of those cases, it just makes things worse. 

For starters, insulin use increases weight gain. A patient of mine, let’s call him Bill, had type 2 diabetes for 10 years prior to coming to my clinic. At the time of diagnosis, his physician started him on a drug that stimulates insulin production.

This method of treating diabetes worked for a while, but slowly and surely his blood sugar—and his weight—began to increase. His doctor responded by upping his medication dose. Again, this temporarily made living with diabetes easier for Bill, but eventually both his blood sugar and his waistline inched up.

In time, Bill was no longer able to keep his diabetes under control with oral drugs, so his doctor prescribed a low dose of insulin.

Over the next few years, his insulin dose was periodically ratcheted upward to keep pace with his rising blood sugar levels, and with every increase, he gained more and more weight. Soon he came to me asking, “Dr. Whitaker, what can I do now?” You see, when I first saw Bill, he was taking 100 units of insulin daily and had put on 100 pounds!

Folks, that’s just bad medicine. Bill’s “diabesity” (diabetes plus obesity), which was contributing to a number of health problems, was clearly exacerbated by insulin. After following my treatment program, which included, among other things, a healthy diet and blood sugar supplements, Bill lost those 100 extra pounds over the course of several years, and his blood sugar normalized without any prescription medication at all.

Another testament to the link between insulin use, diabetes and weight gain is the fact that 90 percent of teenagers with type 1 diabetes sometimes skip their insulin doses in order to prevent weight gain. I certainly don’t advocate this practice (especially since type 1 diabetics need insulin to survive), but it goes to show just how many people have experienced this potential downside to taking supplemental insulin.

In my next blog post, I’ll reveal another reason why I’m down on supplemental insulin for treating diabetes.

Diabetes and Periodontal Disease

Tuesday, March 16, 2010 by Dr. Julian Whitaker
People living with diabetes are at higher risk of developing periodontal disease than people without blood sugar problems.

Periodontal disease, or gum disease, occurs when the gums become infected and inflamed. Signs that you may have periodontal disease include:
  • red, sore, swollen gums
  • bleeding gums
  • loose or sensitive teeth
  • bad breath
  • trouble chewing
According to the CDC, young adults dealing with diabetes have about twice the risk of periodontal disease than those without diabetes. Also, people with poorly controlled blood sugar levels are nearly three times more likely to have severe forms of gum disease, and they typically lose more teeth than those without diabetes.

As is the case with most diabetes risk factors, a primary culprit behind the increased risk of periodontal disease is damage to blood vessels due to the inability to maintain blood sugar levels within the healthy range. Without nourishment and removal of wastes from their tissues, the gums become less resistant to infection, setting the stage for periodontal disease.

Another reason people with diabetes are much more prone to periodontal disease is because they are prone to nutritional deficiencies. Diabetes is nutritional wasting disease, and affected individuals often have low blood levels of vitamin C, zinc, and other water-soluble vitamins and minerals. Zinc is necessary for tissue healing, and vitamin C is required for collagen formation. In fact, scurvy, the quintessential vitamin C deficiency disease, is characterized by bleeding gums and loose teeth.

And if you smoke, you are at even higher risk. Statistics show that diabetics who smoke and are 45 years or older are 20 times more likely to develop severe gum disease than people who don’t smoke.

The best way to lower your risk of developing periodontal disease is to brush and floss every day, take a good daily vitamin and mineral supplement, and visit your dentist on a regular basis.

Two Supplements for Healthy Eyes

Friday, March 12, 2010 by Dr. Julian Whitaker
When blood glucose levels remain elevated for an extended period of time, sticky sugar molecules can attach to protein molecules in a process called glycation. Glycation of protein molecules creates irreversible cross-links between adjacent protein molecules. This cross-linking creates new protein structures called AGEs (Advanced Glycosylation End products).

If you’re dealing with diabetes, you’ll want to be particularly aware of this because, among other things, AGEs can cause tissues like the collagen in your blood vessels to become stiff and lose their flexibility. This is a major culprit behind many diabetic complications, including cataracts and diabetic retinopathy.

But, the good news is that there are two supplements for diabetes that are especially good for your eyes. 
  • Grape Seed Extract. Grape seed extract is a powerful antioxidant that protects blood vessels and capillaries from free-radical damage. Research shows that grape seed extract can also help prevent diabetic retinopathy. The initial dose is one mg per pound of body weight for the first week, in divided doses with meals, continuing with a maintenance dose of one-half this amount. Round your weight up or down to the nearest 50 pounds.  For example, if you weigh 210 pounds, take 200 mg a day for the first week, and then continue on 100 mg a day.

  • Benfotiamine. According to researchers at Case Western Reserve University in Cleveland, Ohio, benfotiamine blocks three of the major culprits responsible for blood vessel damage in patients with elevated blood sugar levels. As a result, it helps prevent retinopathy, neuropathy, and other diabetes complications.
Although benfotiamine is found in small quantities in garlic, shallots, leeks, and onions, you’d have to eat an awful lot of these vegetables to obtain therapeutic doses. If you want to forego the bad breath, I suggest you use benfotiamine in capsule form. Look for it in your local health food store. Typical doses range from 150 to 450 mg daily.

Diabetes and Activity Level

Wednesday, March 10, 2010 by Dr. Julian Whitaker
People who lead a sedentary lifestyle are at higher risk of developing type 2 diabetes. In fact, some Harvard researchers found that the more TV you watch, the more likely you are to suffer with diabetes and weight problems and diabetes. Why? Because lack of exercise lowers insulin sensitivity and increases the possibility of metabolic syndrome.

Regular exercise is a must if you’re looking to maintain a healthy weight and control blood sugar levels. Researchers at Stanford and the University of California Berkeley who followed nearly 6,000 men for 14 years determined that increased physical activity was extremely effective in preventing type 2 diabetes. And it was especially protective for men with the highest risk of developing diabetes—those who were overweight or had a family history of the disease.

Aerobic exercise will lower blood sugar and burn calories, while resistance training, such as
weightlifting, builds muscle and improves long-term insulin sensitivity. You don’t have to run marathons—just get active. Brisk walking is one of the easiest exercises.

The most important thing is to choose something you enjoy and stick with it. I recommend at least 30–45 minutes of vigorous exercise four or more days per week.

Diabetes and Weight

Monday, March 8, 2010 by Dr. Julian Whitaker
Are you looking for natural remedies for diabetes?  If so, one thing you can do is maintain a healthy weight.

One of the most significant risk factors for type 2 diabetes is obesity. Statistics show that 90 percent of all people with type 2 diabetes are overweight. In fact, the link between diabetes
and obesity is so strong that it’s led to the coining of a new term, diabesity.

Where you store those extra pounds is also an issue. If you’re a person living with diabetes and you carry your weight in the abdominal area, you are at an even greater risk of insulin resistance and diabetes. That’s because abdominal fat is more metabolically active than fat stored in the hips or buttocks. It is more easily broken down into free fatty acids that enter the bloodstream, interfere with the action of insulin, and raise triglyceride and glucose levels.

The good news is, for most people, getting a handle on weight is all it takes to minimize diabetes risk factors.

Manage Diabetes with Two Key Herbs

Friday, March 5, 2010 by Dr. Julian Whitaker
There are two herbs that I recommend to help you manage blood sugar and protect against diabetes complications: Gymnema sylvestre and banaba leaf extract.

Gymnema sylvestre is an extract from the leaves of a climbing plant native to the forests of central and south India that has been used since the sixth century BC. The leaves of the plant contain gymnemic acids, which have been shown to slow the transport of glucose from the intestines to the bloodstream. This, in turn, helps keep blood sugar levels in the healthy range. I recommend a maintenance dose of 200 mg of Gymnema sylvestre daily. For extra support, try 400 mg daily.

Banaba leaf extract (Lagestroemia speciosa), which comes from Asia, contains colosolic acid. Colosolic acid promotes glucose transport into cells, making it easier to maintain blood sugar levels within the healthy range. In one Japanese clinical trial, 24 people living with diabetes were given a supplement containing banaba leaf or a placebo three times a day for four weeks. While those taking the placebo showed no improvement, significant blood sugar declines were observed in the individuals taking the herb.

I recommend 48 mg of banaba leaf daily.

Managing Diabetes with Vanadium

Thursday, March 4, 2010 by Dr. Julian Whitaker
Vanadium, a trace mineral, is an excellent natural treatment for diabetes. I believe it is one of the most effective and intriguing blood sugar supplements. In fact, studies show that vanadium (as vanadyl sulfate) mimics insulin in the body and helps maintain blood sugar levels well within the healthy range.

One specific study involved individuals who were trying to treat type 2 diabetes. They each  received 50 mg of vanadyl sulfate twice a day for four weeks, followed by a placebo for four weeks. At the end of the study, they were found to have a 20 percent reduction in average fasting blood sugar, which lasted well into the placebo period after the mineral was discontinued.

The only reported adverse effect was minor gastrointestinal distress during the first few days of the study. The suggested dose of vanadyl sulfate is 100 mg per day.

Living with Diabetes? Enjoy Dark Chocolate

Tuesday, March 2, 2010 by Dr. Julian Whitaker
I know you are thinking that sugar-laden chocolate is the last thing people who are trying to manage diabetes should be eating. But, while it is true that chocolate has fat and calories—and it tastes way too good to be good for you—the health benefits of dark chocolate cannot be denied, even to people living with diabetes.

Italian researchers discovered that dark chocolate significantly improves markers of insulin sensitivity. It can also decrease fasting insulin and glucose levels, as well as insulin and glucose responses to the glucose tolerance test.

High-quality dark chocolate is sold in health food, specialty, and grocery stores. Look for bars that contain 70 percent cocoa or more. Don’t be put off by the fat content, and expect it to have some sugar. Unsweetened dark chocolate is extremely bitter and, even sweetened, it is for some an acquired taste, so shop around for a brand you like.

I urge my patients to enjoy it in moderation so that it doesn’t interfere with their ability to maintain blood sugar levels. So, if you are dealing with diabetes, know that a square or two of dark chocolate every other day or so is enough to satisfy your sweet tooth. Just be sure to keep caloric intake steady, and eat your dark chocolate in place of, rather than in addition to, other foods or snacks.

Diabetes Complication #2: Foot Problems

Friday, February 26, 2010 by Dr. Julian Whitaker
Diabetes complications are vast, but one of the most common diabetes complications is problems with the feet. 

For people with diabetic neuropathy, diminished sensation in the feet can lead to a host of problems, including an underestimation of wound severity. At the same time, impaired circulation makes diabetics more susceptible to infection and retards wound healing. 

For most of us, small blisters or scrapes on the feet are minor problems that go away within days, but for people living with diabetes, they can spell disaster. This is why I tell people who are managing diabetes that they can never pay too much attention to their feet.

Here is a list of common foot problems that, if present in diabetics and left untreated, can increase risk of foot amputation.
  • Athlete’s Foot
  • Toenail Fungus
  • Calluses
  • Corns
  • Blisters
  • Bunions
  • Dry Skin
  • Foot Ulcers
  • Ingrown Toenails
  • Plantar Warts

Diabetes Complication #1: Heart Disease

Wednesday, February 24, 2010 by Dr. Julian Whitaker
Much of the research on the relationship between diabetes and heart disease has come from the Framingham Heart Study.

Started in the early 1950s, this study, which has followed the medical history of thousands of residents of Framingham, Massachusetts, has provided a gold mine of data showing how people living with diabetes are at dramatically increased risk of heart disease and related health concerns.

Other studies have demonstrated that even in the absence of other heart disease risk factors, such as high blood pressure, smoking, high cholesterol, or a family history of heart disease, people living with diabetes are still at a much higher risk of heart attack, stroke, and death from cardiovascular disease. They’re also more likely to be concerned about their blood pressure health. Why is this?

The most common type of heart disease, coronary artery disease, is primarily a disease of the blood vessels, or coronary arteries, that supply the heart muscle with vital oxygen and nutrients. In a process known as atherosclerosis, the artery walls become narrowed and hardened with buildups of cholesterol and cellular debris, which can restrict blood flow and impair circulation. If the blood flow through these arteries is severely restricted, angina (chest pain caused by insufficient oxygen to the heart muscle) may result. And if a blood clot lodges in a narrowed artery, a heart attack or stroke may occur.

When you throw elevated blood sugar into the mix, the situation only gets worse. Excess blood sugar makes the blood less viscous, causing impaired circulation. And high levels of insulin, also characteristic of type 2 diabetes, damage the arteries and contribute to atherosclerosis. So it makes sense that people living with diabetes are also at increased risk of developing heart disease. Fortunately, taking steps to manage blood sugar levels can help to reduce this risk.

Diabetes Complications

Tuesday, February 23, 2010 by Dr. Julian Whitaker
One reason why diabetes complications are so common is because diabetes is a nutritionally wasting disease.

People dealing with diabetes experience dramatic increases in urination as the kidneys attempt to get rid of excess glucose. Along with excess glucose, however, massive amounts of water-soluble vitamins and minerals also are lost.

Numerous studies have shown that people living with diabetes tend to have low cellular levels of magnesium, zinc, vitamins B6 and C, and other essential nutrients.

As a result of these nutritional deficiencies, people living with diabetes are at increased risk of premature death and disability. Diabetes ravages the blood vessels and nerves. This can lead to blindness, neuropathy, erectile dysfunction, urinary incontinence, impaired digestion, amputation, and gum disease.

Thankfully, there are natural treatments for diabetes and we’ll be discussing many of them in this blog.

Metabolic Syndrome

Friday, February 19, 2010 by Dr. Julian Whitaker

In addition to being the driving force behind type-2 diabetes, insulin resistance is also part and parcel of a condition known as metabolic syndrome.

Identified in the mid-1980s by Stanford University researcher Gerald Reaven, MD, metabolic syndrome, initially called  syndrome X, is a cluster of disorders that includes obesity, high blood pressure, elevated triglycerides, low HDL cholesterol (often referred to as “good” cholesterol since it ushers excess cholesterol out of the body), and increased risk of heart disease and type 2 diabetes.

Dr. Reaven, observing that these seemingly unrelated disorders cropped up so often in the same individuals, determined that the one underlying constant was insulin resistance. In addition to insulin resistance, here are some of the other risk factors associated with metabolic syndrome:

  • Abdominal obesity: an accumulation of excess fat around the waist
  • Age: the older you are, the higher your risk
  • Sedentary lifestyle
  • Hormone imbalances
  • Poor diet: a diet high in saturated and trans fats and sugar

Fortunately, by following the alternative treatments for diabetes that we’ll be sharing here, you will not only protect yourself from diabetes, but also lower your risk of metabolic syndrome.

Diabetes and Weight

Wednesday, February 17, 2010 by Dr. Julian Whitaker

One of the most significant risk factors for type-2 diabetes is obesity.

Statistics show that 90 percent of all people with type-2 diabetes are overweight. In fact, the link between diabetes and obesity is so strong that it’s led to the coining of a new term, diabesity.

Where you store those extra pounds is also an issue, in terms of your ability to control blood sugar. For example, if you carry the pounds in the abdominal area, you are at an even greater risk of insulin resistance and diabetes. That’s because abdominal fat is more metabolically active than fat stored in the hips or buttocks. It is more easily broken down into free fatty acids that enter the bloodstream, interfere with the action of insulin, and raise triglyceride and glucose levels.

The good news is, for most people, getting a handle on weight is a great way of beating diabetes. Check this blog often for tips on how to lose weight and other natural remedies for diabetes.

Three Diabetes Risk Factors

Tuesday, February 16, 2010 by Dr. Julian Whitaker

While there are many diabetes risk factors, I’d like to focus on three:

1. Prescription Drugs. Taking certain prescription drugs can increase your risk of developing diabetes. Common culprits include: corticosteroids (typically prescribed to treat asthma and arthritis), thiazide diuretics (often used to treat heart failure and high blood pressure), and antipsychotic drugs. British researchers also found that beta blockers (medications used to treat hypertension) increase the risk of diabetes by 50 percent. If you are taking any of these medications, talk to your doctor about safe, natural alternatives to these side effect-riddled drugs. Doing so may help you manage diabetes.

2. Level of Activity. People who are inactive are at higher risk of developing type-2 diabetes. In fact, Harvard researchers found that the more TV you watch, the more likely you are to develop diabetes and weight problems. This is because lack of regular exercise lowers insulin sensitivity and increases the possibility of metabolic syndrome.

3. Smoking. Everyone knows smoking increases your risk of cancer, but many probably don’t know that it is also a risk factor for type2 diabetes.

There are many other diabetes risk factors, which we will explore in this blog. We’ll also carefully examine the many alternative treatments for diabetes and how you can incorporate them into your daily life.


Diabetes Risk Factors You Must Be Aware Of

Friday, February 12, 2010 by Dr. Julian Whitaker
Just about anyone can develop type 2 diabetes, but research has shown that certain individuals seem to be more susceptible than others. Let’s take a look at two common type 2 diabetes risk factors.

Genetics

Some research has found that people who have been diagnosed with type 2 diabetes typically have at least one close relative who has the disease. That being said, if you have a family history of diabetes, it is important that you take steps now to manage the risk factors that you can control so you can avoid diabetes and its complications.

Age

According to recent findings published by the CDC, the age bracket with the highest percentage of diagnosed and undiagnosed diabetes is the 60+ age group.

However, the CDC also found that of the approximate 1.6 million new cases of diabetes that
were diagnosed in people aged 20 years or older in 2007, most of them (approx. 819,000)
occurred in those aged 40–59 years.

Furthermore, while there are no firm statistics available, more and more young adults and children are now being diagnosed with type 2 diabetes—a disease that has historically been confined to adults aged 40 years and older.

Additional diabetes risk factors will be discussed in future blog postings.  I’ll also be sharing natural remedies for diabetes.  Stay tuned.

Differences Between Type 1 and Type 2 Diabetes

Thursday, February 11, 2010 by Dr. Julian Whitaker
Type 1 diabetes, sometimes referred to as insulin-dependent diabetes or juvenile
diabetes (because it usually appears before the age of 20, but it can present at any
age), is caused by an autoimmune attack on the insulin-producing cells in the pancreas. Researchers aren’t sure exactly what causes the immune system to go awry, but
viral infection, vitamin D deficiency, and genetic predisposition are possible causes. Whatever the reason,  the damaged pancreas is unable to produce adequate insulin, resulting in the inability of  glucose and other nutrients to enter the cells.

Type 1 Diabetes Signs and Symptoms

The classic presentation in type 1 diabetes is extreme hunger as the body tries to compensate for this inability to feed its cells—and rapid weight loss as the cells are unable to utilize food, regardless of how much is eaten. In addition, untreated individuals with type 1 diabetes are extremely thirsty, drink copious amounts of fluids, and urinate excessively as the body attempts to dilute and get rid of extremely high levels of glucose in the blood.

Type 1 diabetes is not as common as you may think—only between five and 10 percent of all people with diabetes have this form of the disease.  Most diabetics have type 2.

Type 2 Diabetes Causes

Type 2 diabetes is also marked by elevated blood glucose levels but for different reasons. Initially, people with type 2 diabetes make plenty of insulin. In fact, they often produce much more insulin than healthy individuals. But as the disease progresses the beta cells become exhausted and insulin production slows gradually and, although rare, may cease altogether.

The problem in this form of the disease involves the insulin receptor sites on the cells’ surfaces—they simply don’t respond to signals to open up to let in glucose and other nutrients, regardless of how much insulin is knocking at the door. This is a condition known as insulin resistance or insulin insensitivity, and it is at the root of 90 percent of all diagnoses of diabetes.

Type 2 Diabetes Symptoms

People with the type 2 form don’t experience the same diabetes signs and symptoms as those with Type 1. In fact, many of them have no symptoms at all. The disease is often discovered only during a routine blood test when a high fasting blood glucose reading, usually in the 150 to 300 mg/dL range, is noted.

The good news is that because the body only becomes “insensitive” or “resistant” to insulin, versus destroying insulin-producing cells , there are many type 2 diabetes treatments available.  We’ll be addressing them in future blog postings.

Treating Diabetes

Wednesday, February 10, 2010 by Dr. Julian Whitaker
Diabetes is a fearsome disorder, yet one we take much too lightly. Few people dealing with diabetes risk factors or borderline elevated blood sugar levels realize the urgency of controlling diabetes in its early stages.

Most are unaware that diabetes is the leading cause of blindness, kidney failure, and amputations in this country or that people who have diabetes are more likely to have—and die of—a heart attack or stroke than those who are able to maintain blood sugar levels that are closer to normal.  Nor do they recognize that diabetes is a primary contributor to conditions such as erectile dysfunction (impotence) and dementia. As a matter of fact, most people either don’t know or tend to ignore the subtle warning signs. It’s time we all pull our heads out of the sand and look diabetes in the eye.

The ability to manage blood sugar levels is largely an issue of lifestyle. In 90 percent of all cases, diabetes is both preventable and treatable.

I’ve been practicing medicine for more than 30 years and I have tens of thousands of diabetes success stories from to people who have followed my protocol of natural diabetes treatments. Many of my patients have called me over the years to  thank me for my alternative treatments for diabetes. “My blood sugars are normal—without drugs.” “I was able to avoid amputation.” “My vision has stabilized.” “Your advice saved my life.”

In future blog postings, I will share what you need to know to take control of your own health so that you, too, can beat diabetes.

Is Type 2 Diabetes in Your Genes?

Friday, February 5, 2010 by Tom Callahan

Diabetes, like most chronic illnesses, is often (and rightly) characterized as a disease of lifestyle. Specific lifestyle choices can create and exacerbate type 2 diabetes, but as Dr. Whitaker has proven time and again, the right lifestyle changes can prevent, treat and even reverse type 2 diabetes as well.

But do some people have the cards stacked against them, where developing diabetes is an inevitable component of their very genetic makeup? To read the latest study in Nature Genetics, you might reach that conclusion.

There's no disputing that there is a strong, inheritable correlation present with type 2 diabetes. If your mother, father, sister or brother has it, your risk of developing diabetes goes up considerably. Your identical twin has diabetes? Your risk is even higher.

Now researchers have identified 10 new genetic variants that lead to differences in glucose levels for non-diabetic people. Half of these genetic differences also correlate to the risk of developing type 2 diabetes.

"Finding these new pathways can help us better understand how glucose is regulated, distinguish between normal and pathological glucose variations and develop potential new therapies for type 2 diabetes," Dr Jose Florez, one of the lead researchers, explained.  

What researchers go on to say is that by studying healthy people without type 2 diabetes, their hope is we can better understand how to treat those people who are currently living with diabetes, or those simply trying to manage blood sugar every day.

No dispute here, it's an admirable pursuit. And most experts concede that the future of medicine will be greatly influenced by the study of the human genome. But a danger few people talk about is this science of medicine instead fueling a belief that if you have a genetic predisposition towards a disease, all you're left to do is throw up your hands and live with it.

The fact is, 55 percent of people dealing with type 2 diabetes are struggling with their weight, and regardless of your genes, diabetes and weight are unquestionably connected.
Another lifestyle correlation -- making regular exercise a part of your life -- dramatically impacts your likelihood of facing type 2 diabetes, now or in the future.

By understanding how to manage your risk -- with the proper diet that promotes insulin sensitivity, with supplements for diabetes that make maintaining blood sugar safe and manageable -- you gain control of your genes, not allow your genes to seal your fate.

The fact that you're reading this means you're already taking steps to understand your role in your own health.

Remember, as Dr. Whitaker says, you're in charge. Not your doctor. Not the system. And, as we'll have to keep in mind as more studies like this come out, not your genes.

 


What You Eat After Exercise Key to Managing Blood Sugar

Friday, January 29, 2010 by Tom Callahan
A recent study in the Journal of Applied Physiology highlights an important point for those living with diabetes or simply trying to maintain healthy blood sugar -- what you eat immediately after exercise can have a dramatic impact on your ability to control your blood sugar and maintain insulin sensitivity.

While it's no surprise that exercise can enhance insulin sensitivity, what we're learning is how to best maintain that benefit for a longer period of time, so you get a more lasting impact from your efforts. When study participants were given post-exercise meals containing relatively low levels of carbohydrates, the benefits for insulin sensitivity were greatest.

When you improve your insulin sensitivity, it's easier for your body to absorb the sugar in your blood stream into your tissues, where it can be stored or used as fuel. One of the main signs of type 2 diabetes is insulin resistance, which is also a significant risk factor for other chronic diseases, like heart disease.

The good news is that efforts to eat modestly after exercise, with low-calorie meals, did not improve insulin sensitivity any more than when study participants ate enough calories to match what they burned off. As anyone who's hopped on a treadmill knows, exercise often increases hunger, and it's good to know you don't have to fight the urge to eat after a workout to still take advantage of the important blood sugar benefits.

Exercise Acts Like A Natural Shot of Insulin

As Dr. Whitaker has pointed out in Health & Healing, exercise dramatically improves your ability to fight diabetes and insulin resistance. That's because exercise actually acts like insulin in the body — the exercising muscle takes up glucose, even when no insulin is present. And if you exercise regularly, the benefits can be long-lasting.

Given the soaring rate of obesity in this country and the connection between diabetes and weight, exercise is more important than ever to stem the epidemic of type 2 diabetes, and keep those with metabolic syndrome from progressing toward full-blown disease. 

As studies have shown, regular exercise (just 30 minutes, five days a week) and a low-fat diet can deliver average sustained weight loss of 10-15 pounds. This alone can help prevent diabetes or reverse the disease if you already have it.

Brisk walking, jogging, cycling, swimming — it's not what you do but your commitment to actually do it that matters. Shoot for 30 minutes 3-5 times a week. Once you start, and you start reaping the rewards, it's that much easier to stick with it!
