Combining resistance training with a caloric deficit maximizes fat mass loss in overweight/obese premenopausal women compared to diet or resistance training alone.

To lose the most fat while keeping your muscle, combine a moderate caloric deficit with a high-protein diet and resistance training. Do not skip the weights just because you are dieting; they are crucial for preserving your metabolic engine and lean tissue. Aim for 3 days of strength training per week, focusing on compound movements with 10-12 reps, and ensure you are eating enough protein (around 1.4g per kg of body weight) to support your muscles during the deficit.

The three treatment groups all showed significant linear decreases in fat mass, but the slope of the decrease became progressively steeper from the RT, to DIET, to RT+DIET.

Why this rating

Randomized controlled trial with a small sample size (n=40, 31 completers) and high dropout rate, limiting statistical power.
