BMI mediates the association between macronutrient quality and phenotypic age acceleration, accounting for approximately 20-30% of the effect.

Dietary changes slow aging partly by helping you maintain a healthy weight. If you are trying to slow biological aging, combining high-quality food choices with weight management strategies will be more effective than diet alone.
