Weight lifting can decrease fat mass, by using up body fat storage as fuel, primarily utilized in damaging the muscles which are essential in the muscle-building process.

So, lifting weights can both build muscle and induce fat loss.

What weight lifting can do?

Does fat turn into muscle?

The simple answer is no. Turning fat into muscle is physiologically impossible, as muscle and fat are made up of different cells. A good analogy to this would be that you cannot turn a banana into an apple they’re two separate things.
