Can Having Overweight Friends Make You Obese Too?

New research suggests obesity may spread through social networks like a virus, and your friends can even live hundreds of miles away! I can’t help it – it’s in my genes. That’s been the surrender slogan for many overweight and obese individuals for years. And who could blame them? Even many doctors and researchers believed your ability to lose weight – or pack on pounds – was a function of your genetic make-up.

Key Insights On Lifelong Weight Control

Successful weight loss is not just a matter of losing pounds. The emphasis needs to be on abandoning body fat and avoiding loss of lean body tissue, primarily muscle mass. Why is this the key to long-term success? Because muscle requires 15 times the energy compared to fat to survive (7.5 Calories per day for muscle versus 0.5 calories per day for fat). The more lean tissue, the more calories one can consume once desirable body weight is achieved. Overall, a moderate diet of at least 1000 calories of high quality food per day and exercise is clearly the best approach because 80% of the weight lost is fat. This plan protects lean body mass, which is critical to keep from gaining the weight back again.
