What this page should prevent.
Do not promise a specific body-composition change for every client. Use resistance training as a high-probability guardrail during dieting.
Geebs coaching takeaway
The study only matters if it changes a behavior.

Questions that cite this source.
Diet muscle-retention answer
How do you avoid losing muscle while dieting?
You reduce muscle-loss risk by giving your body a reason to keep muscle: lift consistently, hit a realistic protein floor, avoid crash dieting, and track strength instead of only tracking scale weight.
Lifting while dieting answer
Does lifting help during weight loss?
Yes. Lifting may not make the scale drop faster, but it can help protect fat-free mass, improve strength, and make more of the loss come from fat instead of tissue you want to keep.
Strength tracking answer
Should you track strength while losing weight?
Yes. Strength tracking gives you a practical signal the scale cannot. If weight is dropping but strength, energy, and protein consistency are collapsing, the plan may be costing too much muscle and function.
