The Healthy Dimensions promotional video provides an overview of the program, and it includes a simple animation of the insulin-carb-hunger cycle that so many people get caught up in.
The essay “Always Hungry? Here’s Why” from the May 16, 2014 edition of the New York Times provides a more detailed description of what happens in this loop. Really understanding how the metabolism works is critical for anyone trying to find the best way of eating for natural healthy weight loss.
There’s one thing I think worth noting, however.
The essay’s authors, David S. Ludwig (professor of pediatrics at Harvard Medical School) and Mark I. Friedman (vice-president of research at the Nutrition Science Initiative), state that reducing carbs to lose weight is a hypothesis. This is true from a strict clinical perspective, but there are studies that indicate the effectiveness of low-carb diets. And the science is pretty well-settled; carbohydrates stimulate the production of insulin, and insulin stores energy (glucose) as fat.
Some people have metabolisms that are less sensitive to carbs than others, perhaps because of their genetic makeup. But people who are more sensitive to carbs can sometimes get caught in the insulin-carb-hunger cycle. They feel like they’re riding an out-of-control roller coaster of dietary cravings, and they need help to break the cycle. That’s what the “body” aspect of the Healthy Dimensions program is all about – helping individuals find the combination of nutrients that’s right for them.
