Even when you’re eating less to lose fat, your body can still build muscle if you lift weights and have enough fat stored.

Untrained individuals undergoing resistance training with a significant caloric surplus achieve high rates of muscle hypertrophy with relatively low concomitant fat accumulation.

Lifting weights helps adults gain muscle — studies show it consistently leads to modest muscle growth when done regularly.

A caloric maintenance state combined with resistance training can result in simultaneous fat loss and muscle gain by mobilizing endogenous fat stores to support muscle protein synthesis.

When people reduce their calorie intake and do strength training, a greater share of the weight they lose comes from fat rather than muscle.

To build the maximum amount of muscle mass while lifting weights, consuming more calories than the body burns is required.
