Does a low resting metabolic rate (RMR)–or “slow metabolism” contribute to weight regain?
A recent study of studies–a meta-analysis–of 124 formerly obese people and 121 controls shows that just 15% of these formerly obese people had low RMRs, or slow metabolism. The rest were normal.
If you are losing weight, one or two pounds weekly, chances are you do not have a low RMR. Chances are you are building muscle and losing fat. A new study of 30 obese women who lost 25% of their excess weight with gastric surgery showed that it’s muscle mass that determines RMR. Burn calories while you sleep: get stronger.
