Leanmaxxing (Body-Fat Reduction)
Lowering body fat is the single biggest natural lever for facial definition.
Evidence grade A
Multiple randomized controlled trials / meta-analyses
Mechanism
Facial adiposity sits in the buccal, submental, and jowl compartments; reducing total body fat de-volumizes them, exposing the underlying mandibular border, zygomatic contour, and cheek hollows.

The full read
Perceived facial attractiveness and health correlate strongly with facial adiposity in controlled studies. Most people first 'find out' they have a jawline somewhere between 10–15% body fat (men). No supplement, tool, or exercise spot-reduces facial fat — only overall energy balance does. This is the highest-leverage, fully-in-your-control intervention on this list.
