How Does Body Recomposition Work?

Body recomposition is the physiological process of simultaneously losing fat and building muscle. For years, conventional wisdom claimed this was impossible without performance-enhancing drugs. Modern exercise physiology has repeatedly debunked that myth: adipose tissue (stored body fat) provides the required energy substrate to fuel muscle protein synthesis when high protein intake and progressive resistance training are present.

The Strategy: Calorie & Carb Cycling

To optimize both adaptations simultaneously, LeanGauge uses an evidence-based calorie and carbohydrate cycling model:

Frequently Asked Questions

Who sees the fastest recomposition results?

Beginners in resistance training, lifters returning from a multi-week layoff (muscle memory), and individuals with body fat above 18% (men) or 26% (women) see the most dramatic simultaneous gains.

Will my scale weight change?

Scale weight often remains stable or moves very slowly during a recomp, even as your body transforms dramatically. Because muscle is denser than fat, track progress using progress photos, waist measurements, and gym strength numbers.

Can I do cardio while recomping?

Yes. Low-intensity steady state (LISS) cardio and daily walking (NEAT) on rest days increase caloric expenditure without interfering with leg recovery or central nervous system fatigue.
