Overeating Triggers Overeating
Jonny's Take, Diet & Weight Loss
Jonny Bowden, author, nutritionist and weight loss coach cuts through all the misconceptions about diet and fitness to help you transform your body, your health and your life.
Want a terrific example of the proverbial "vicious cycle" when it comes to diet? Check this out: Overeating can actually stimulate a metabolic response in the brain that induces cravings to eat more. The result? A cycle of elevated calorie consumption that can lead to obesity, diabetes and insulin resistance.
We've long known that inflammation is a huge part of every degenerative disease from Alzheimer's to heart disease, and it's a big part of obesity as well. Researchers at the University of Wisconsin-Madison and the University of California-San Diego found that overeating can induce inflammatory responses that underlie Type ll Diabetes and obesity. So what's the big news? We've known since forever that eating too much makes you fat.
One of these fat cells is not like the other
We all have body fat. It's necessary for proper body function. While a healthy percentage of body fat varies greatly, according to the American College of Sports Medicine a healthy range for women under 40 is 20-35%, for men 8-22%. (The ranges change for those over 40 and for fitness standards.) But a recent study reveals that one fat cell isn't necessarily like another. In obese people, fat cells appear "sick."
Compared to fat cells taken from lean people, the fat cells from obese people were deficient in several ways. For example, the endoplasmic reticulum -- which helps cells synthesize proteins -- was stressed in the fat cells of obese people. This stress of the endoplasmic reticulum could inhibit or change the body's production of protein and could lead to insulin resistance (a contributing factor for obesity).
