The Claim
In men with overweight or obesity, a dietary protein intake of 0.9 g/kg/day for five weeks has no significant effect on resting metabolic rate, respiratory exchange ratio, or skeletal muscle mitochondrial oxidative phosphorylation protein content.
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 men with overweight or obesity, eating 0.9 grams of protein per kilogram of body weight per day for five weeks does not change resting metabolic rate, the ratio of oxygen to carbon dioxide exchanged during breathing, or the levels of proteins involved in mitochondrial energy production in muscle.
See the scientific wording
In men with overweight or obesity, reducing dietary protein to 0.9 g/kg/day for five weeks does not significantly alter resting metabolic rate, respiratory exchange ratio, or skeletal muscle mitochondrial oxidative phosphorylation protein content.
When protein intake drops, the liver releases a signaling molecule called FGF21, which tells fat tissue to burn more energy as heat. This causes the body to lose fat even when total calories stay the same, but it does not change how much energy the body uses at rest or how many energy-producing machines are in muscle cells.
What the research says
1 studyWhen overweight men ate less protein and more carbs but kept eating the same total calories, their bodies didn’t burn more or less energy at rest, and the energy-making parts in their muscles stayed the same — even though they lost some fat.
