Body Recomposition

2.1

Body Recomposition: Your weight can stay the same while your body changes.

5 sections, about 10 minutes in total

Both

Fat loss and muscle gain at the same time are both documented in the right conditions.

Same weight

The same weight on the scale can hide real change. Fat lost and muscle gained cancel out.

Three things

Three things make it work. Those are a small calorie deficit, enough protein, and strength training that gets harder over time.

Is this for you?

What is body recomposition?

Body recomposition means losing fat and building muscle over the same period, so your weight stays about the same while your body changes shape. It works from many starting points, some faster than others. Tap one to see why.

This is simplified from the recomposition research (Barakat et al., 2020). Trained, lean lifters can still recompose, but it is slow. Separate build and fat loss phases often work better for them.

What the evidence says

What the research says about losing fat and building muscle together.

You can do both at once. It works best with a small calorie deficit, enough protein and strength training. A flat scale is normal while it happens.

The claimLosing fat and building muscle at once is impossible.
What the evidence saysThe trials do not support this. Controlled studies show people losing fat and gaining muscle over the same period. It is clearest in beginners, people returning after a break, and people starting with more body fat.
The claimIt only works if you are a total beginner.
What the evidence saysPartly true. Beginners and returners recompose fastest. Trained lifters can too, just more slowly.
The claimA flat scale means it has stalled.
What the evidence saysA flat scale is what recomposition looks like. Fat lost and muscle gained cancel out on the scale. Your lifts and your waist measurement still change.
The claimEnough protein protects my muscle while I lose fat.
What the evidence saysThis is well supported. In a calorie deficit, people who eat more protein keep more muscle, and sometimes gain some, compared with people who eat less.
The claimA steeper calorie cut will get me there faster.
What the evidence saysNot for this goal. A large deficit leaves too little energy to build muscle, so you lose muscle along with fat. A small deficit works better.

These summaries reflect the cited research and will change if the research changes. How fast recomposition happens varies a lot with training history and starting point. This is coaching context, not a prescription.

How it works

How you lose fat and build muscle at the same time.

You eat a little less than you burn, so your body uses stored fat for energy. You eat enough protein, so your body has what it needs to build muscle. You lift weights, so your body keeps muscle and loses fat instead of losing both. Click through the four steps.

Tap a step to open it. Each one carries the detail.

Why the scale stays flat

A pound of fat lost and a pound of muscle gained cancel out on the scale but look visibly different on your body. During a recomposition, a flat scale with rising lifts and a shrinking waist means the plan is working rather than stalling.

Section 4 of 5:

What to do

Combine a small deficit with progressive training.

Six habits run fat loss and muscle gain at the same time. Protein and progressive training are the two it does not work without. Tap a habit to see what to do.

Recomposition moves slowly on the scale and shows up mostly in the mirror. Anyone promising fast results on both is overselling.

What we track

How to measure progress without the scale.

Fat lost and muscle gained cancel out on the scale. Use these six measures instead. Tap one to see how.

How fast recomposition happens varies a lot with training history and starting point. Your own month over month measures are the reference.
