An Oldie but Goldie

The implication of this basic endocrinology is that obesity is caused not by eating too much and sedentary behavior, but by a disruption of the hormonal and enzymatic regulation of fat tissue caused by the easily digestible, refined carbohydrates and sugars that we do eat. Indeed, by this logic, calorie-restricted diets – starvation and semi-starvation diets as used in the studies Ms. Parker-Pope discusses–can be thought of as particularly counterproductive ways to reduce carbohydrate consumption and so insulin levels, starving the body, as they do, of the energy required to effectively run metabolic processes.

In the past decade, clinical trials have repeatedly demonstrated that when obese and overweight individuals consciously restrict the carbohydrates they eat, but not calories, they not only lose weight, on average, but their heart disease and diabetes risk factors improve significantly. Their insulin resistance, in effect, resolves. Those of us who have lost weight ourselves and witnessed the effect of these diets on our patients can confirm that this is exactly what happens.
