Metabolism Slowdown Causes Weight Re-gain

I have some bad news for you. According to scientists from New York's Presbyterian Medical Center at Columbia University, folks who succeed in losing weight tend to suffer from a lower than expected metabolic rate. This means that if you lose weight, you will burn fewer calories each day than someone of the same weight who was never overweight. This metabolism slowdown will probably cause weight re-gain.

Seems unfair, doesn't it?

In the study, subjects who lost 10% of their bodyweight and kept it off for up to one year were studied, along with a group that just recently lost 10% of their bodyweight, and a control group.
All subjects were studied for 24 hours straight, to determine how many calories they burned.

Reference
Am J Clin Nutr. 2008 Oct;88(4):906-12.Related Articles, Links Long-term persistence of adaptive thermogenesis in subjects who have maintained a reduced body weight. Rosenbaum M, Hirsch J, Gallagher DA, Leibel RL.

Results showed that both weight loss groups burned fewer calories in the 24 hours than the control group, even though subjects were matched for weight and gender.

This decrease in expected calorie burning is just one of the many reasons you will find it easier to regain weight after you lose weight.

So what can you do?

You must do everything you can to boost your metabolim. I highly recommend to all of my clients that they use interval training or high-intensity cardio rather than low-intensity cardio, and that they also engage in high-intensity resistance training three times per week. By performing high-intensity exercise, you will put up the greatest fight against your handicapped metabolism.
