Findings of a study of obese and non-obese subjects indicate that body weight regulates cholesterol metabolism in patients with type 2 diabetes. Cholesterol absorption efficiency is lower and cholesterol synthesis is higher in obese patients.
Simonen and colleagues of the University of Helsinki, Finland, studied cholesterol metabolism in 22 obese (mean body mass index, 33.4 kg/m2) and 20 non-obese (mean body mass index, 24.1 kg/m2) patients with type 2 diabetes. Age, blood glucose levels, and dietary intake of calories, cholesterol, fat, and plant sterols were similar in the two groups.
Although serum cholesterol levels were similar in the two groups, bile acid synthesis, fecal neutral sterol excretion, and cholesterol synthesis were higher in the obese patients than in the non-obese patients. On the other hand, sitosterol and cholesterol ratios were significantly lower in the obese than in the non-obese group, suggesting low cholesterol absorption in obese patients.

The Key To Diabetic Diet – Still Up For Debate
What’s more important than any current diet plan to improving health? There is no way to avoid how critical exercise is to improving blood sugar control. The American Diabetes Association generally follows the health recommendations outlined by the USDA (United States Department of Agriculture). They encourage people with diabetes to have a diabetic diet that favors starches and grains. In contrast, some have argued that a diet that is rich in protein and healthy fats can drastically reduce the risk of Type 2 Diabetes and can improve health. Healthy fats generally include monosaturated and polysaturated fats, and trans fats and saturated fats are often discouraged. Dieticians take positions that run anywhere from complete carbohydrate restriction to strongly encouraging the consumption of breads and grains as in the diabetes food pyramid.
Two summers ago, I went to Hong Kong for several weeks. I ate a diet that was relatively high in fruits (about 5 servings a day), and I also ate a great deal of grains, vegetables, and nuts. I was walking everywhere, and my commute to work was about 30 minutes each way (which required about 20 minutes of brisk walking and a 10 minute ride on the subway MTR). I also did a great deal of sightseeing and walking tours. In addition, I was weight lifting several times each week. I was continuously getting exercise.
During my stay, my daily insulin requirements plummeted. All of the walking was using the energy from the foods I was eating, and I lost a lot of weight. I needed fewer hours of sleep each night, and I rarely felt tired. Surprisingly, the more exercise I got, the less hungry I was.
I think that this taught me two very important things:
1) A sedentary lifestyle is far more detrimental to my health than my diet
2) When I get more exercise, I usually have more energy and have less hunger and require less sleep
I think that reducing insulin intake is important in improving diabetes health, but I strongly believe that the best way to do that is through exercise.

Diabetes And Obesity - How Wealth is Destroying Our Health
It would be wrong to say that what we eat is the only reason for an increase in the cases of diabetes, especially Type 2 Diabetes. Rising cases of obesity are also undoubtedly related to insufficient physical activity and excessive caloric intake. Nevertheless, the statistics are staggering: In 1980, there were only approximately 25 million people in the world with Type 2 Diabetes. By today, only 30 years later, some estimate the number to be above 200 million. That is an increase of 800%. It blows my mind.
In America and around the world, our greatest technological advances have in some ways been to our detriment. We are wealthier than at any time in the past, but we have not been trained for healthy diet and active lifestyle. Americans are working long hours, but most work at desks or behind counters. On average, Americans eat out approximately one time each day.
When we eat out, we are eating larger portions. In addition, most of the foods available at restaurants, especially fast food restaurants, are loaded with saturated fat and refined carbohydrates. These foods are cheap to produce, and they are convenient.
What can we do? I often find myself angry at what is being offered to children in school. I remember the school lunch at my elementary school, and it was like eating fast food. At the time, though, I thought it was good and I didn’t know otherwise. Despite being wealthier than ever in the past, we are not spending money on keeping children healthy.
I will stop ranting now. This is a topic that I am truly fervent about, though. Health needs to be cool, and eating junk needs to be criticized. Don’t be fooled by processed foods and fad diets.
