What is the difference between BMR and RMR?

BMR (Basal Metabolic Rate) is measured under strict laboratory conditions following overnight fasting and complete physical rest. RMR (Resting Metabolic Rate) is measured under looser criteria without fasting, making it slightly higher.

Can I increase my BMR to lose weight faster?

Yes. The most effective way to increase your BMR is by building lean muscle mass through progressive resistance training, as muscle tissue burns more calories than fat.

How many calories should I eat if my BMR is 1,600?

To lose weight safely, consume fewer calories than your active daily needs (TDEE) but generally above your BMR. Eating fewer calories than your BMR for extended periods is not recommended without medical supervision.
