A lot of people talk about lean bodybuilding, but what's really at stake is often overlooked. Indeed, when we talk about lean bodybuilding and muscle definition, we're really talking about weight loss caused by a reduction in fat mass, not overall mass, which also includes muscle.

That's what makes this objective so difficult, because you'll need to have a calorie intake slightly lower than your daily expenditure in order to keep your muscle while burning fat.

The supplements that will help you with your weight loss will be low-calorie, protein-rich supplements to protect muscle mass in the first instance, but also stimulants to promote fat loss.
