Energy balance

Lorcaserin (10 mg twice daily) reduces body weight in overweight/obese adults primarily by decreasing energy intake, with no significant effect on energy expenditure or substrate oxidation.

Take lorcaserin (10 mg, twice daily) as prescribed. It works by reducing your appetite and energy intake, not by speeding up your metabolism. Expect weight loss to be driven by eating less, and understand that your body's energy expenditure will naturally decrease as you lose weight, which is a normal metabolic adaptation, not a failure of the drug.
