The Claim

Increases in strength during caloric restriction with high-volume resistance training occur independently of changes in fat-free mass, indicating that neural or technical adaptations, rather than muscle hypertrophy, are the primary mechanism.

Source: A 4-week caloric restriction with high volume resistance-training and high-protein diet does not increase fat-free mass sparing but increases strength.

Supports is higher

Support is ahead, but a single strong opposing study can change this.

These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.

How it works
1 study reviewed
In plain English

During calorie restriction combined with high-volume resistance training, strength gains happen without an increase in muscle mass, and these gains are due to improvements in nervous system efficiency or movement technique, not muscle growth.

See the scientific wording

The increase in strength during caloric restriction with high-volume resistance training may occur independently of changes in fat-free mass, suggesting neural or technical adaptations rather than muscle hypertrophy as the primary mechanism.

Why this might work

The nervous system sends stronger signals to the muscles during lifting, allowing the muscles to contract more forcefully without getting bigger.

    People got stronger while dieting, but their muscle mass didn’t increase—so they probably got better at using their muscles efficiently, not because they grew bigger muscles.
