Traditionally, a low-fat, high carbohydrate diet is recommended for the obese and type II diabetics. This low-fat approach is based on simple math. Fat has about twice as many calories per gram as carbohydrates and protein. Regardless of the lower calorie content, applying the theory has proven disastrous. It has secured America a seat in the worldwide Fat Ass Hall of Fame while giving birth to a diabetes epidemic. No surprise, math isn’t the best measure of a foods effect on the body. Biochemistry is – go figure.
In contrast to carbohydrates, eating fat (not trans fat, but naturally occurring fat) has proven to be the most important method for ensuring fat loss and warding off diabetes. This is courtesy of fats inability to spike the fat storing hormone insulin – and prevent us from feeding our pie hole excess calories. Thus, despite eating fat in the form of grass fed beef, seeds, nuts, avocados, coconut oil or fish, you won’t suffer from unsightly belly fat. This phenomenon has been proven many times.
The American Journal of Clinical Nutrition recently showed that eating twice as much fat led to greater weight loss. Researchers compared two eating plans that were similar in caloric intake but vastly different in fat consumption. Obese individuals who consumed 61% fat energy for eight weeks lost 18 pounds; those consuming a mere 30% fat lost 14 pounds (they replaced the fat intake with 46% carbs). (1) Far more staggering than the differences in weight loss are the differences in biochemistry among the two groups.
Low fat, high carbohydrate eaters have the perfect biological environment for obesity and type II diabetes. Their blood levels of glucose, insulin and triglycerides skyrocket.(2) The Nurses’ Study by Harvard found that women who adhere to the Big Fat Scam and eat mostly carbohydrates increase their risk of diabetes 2.5 times! Men are not immune to the deadly carbohydrate effect.
Diabetics usually die early from heart disease, twice as often as those without diabetes. It is so damaging that it can erase 11-20 years from a persons lifespan. Currently, an estimated one in four American’s suffer from it. One in three born in the year 2000 will succumb to the Big Fat Scam and therefore suffer from diabetes according to The Journal of the American Medical Association. (3)
The best way to avoid being an honorary member of the Fat Ass Hall of Fame and the diabetes epidemic is to avoid the Big Fat Scam. Start eating more fat (avoid trans fats, of course, and give preference to fats with omega-3’s). Judge your food based on its effect on insulin (via glycemic load), count calories second. Stop futzing around with fad diets and self-proclaimed weight loss gurus who push wanton pill and supplement use as well as whole grains, fruit juice, sugary yogurt, candy bars disguised as health bars and most anything else served out of a box, package or window.
