What does this rating mean?

Multiple consistent meta-analyses or a position stand. Sufficient basis for a fixed choice in the coaching.

Findings

Caloric deficit drives fat loss; higher baseline body fat allows more aggressive deficits, while slower weight loss better preserves lean mass. Protein at 2.3-3.1 g/kg FFM/day during a deficit and resistance training best preserve lean mass; no single diet type is universally superior.

Who this applies to

General and athletic populations

What to keep in mind
