Some dieters are at higher risk for osteoporosis. Obsessing over those last 5 to 10 lb may be hurting your bones. Healthy weight women who were weight cyclers (losing, then regaining 10 lb or more) had 10% more fractures and lower bone mineral density than nondieters, according to recent research.
In another study, normal weight women who rigidly structured every meal had higher levels of cortisol, a stress hormone that is thought to negatively affect bone formation, calcium absorption, and estrogen levels. So, if you’re at a healthy weight but are dieting to reach some magic number on the scale — relax! It’s still important to eat a healthy diet, but don’t scrutinize every bite, and try to enjoy your food. Your bones will thank you.
