The Claim
A 4-week intervention involving 40% caloric restriction, a high-protein diet at 2.3 g/kg/day, and resistance training results in significant reductions in body mass (approximately 4.2 kg), fat mass (approximately 3.7 kg), and percentage of body fat (approximately 3.5%) in resistance-trained individuals, irrespective of training volume.
What the research says
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.
In resistance-trained individuals, following a 4-week diet with 40% fewer calories, 2.3 grams of protein per kilogram of body weight, and resistance training leads to a loss of about 4.2 kg of body mass, 3.7 kg of fat mass, and a 3.5% reduction in body fat percentage, regardless of how much training is done.
See the scientific wording
A 4-week 40% caloric restriction with a high-protein diet (2.3 g/kg/day) and resistance training leads to significant reductions in body mass (approximately 4.2 kg), fat mass (approximately 3.7 kg), and percentage of body fat (approximately 3.5%) in resistance-trained individuals, regardless of training volume.
When the body gets far fewer calories than it needs, it breaks down stored fat for energy. Eating a lot of protein and lifting weights keeps the muscles from breaking down, so the weight lost comes mostly from fat.
What the research says
1 studyWhen trained people eat less food (40% fewer calories), eat lots of protein, and lift weights for four weeks, they lose about 4 kg of weight and 3.7 kg of fat—no matter if they lift a little or a lot. The study proved this happens the same way for both groups.
