The Claim
High-protein intake at 1.6 g/kg/day during calorie restriction and resistance training reduces leptin levels in young women with overweight, and time-restricted eating does not further reduce leptin levels beyond the effect of high-protein intake.
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 young women with overweight, consuming 1.6 grams of protein per kilogram of body weight per day during calorie restriction and resistance training lowers leptin levels. Adding time-restricted eating does not lower leptin levels any further.
See the scientific wording
High-protein intake (1.6 g/kg/day) during calorie restriction and resistance training significantly reduces leptin levels in young women with overweight, but time-restricted eating does not provide additional leptin-lowering effects beyond protein intake.
Eating more protein while cutting calories and lifting weights causes the body to burn fat for energy instead of storing it, which shrinks fat cells. Smaller fat cells produce less leptin, a hormone that signals fullness. At the same time, protein keeps muscle from breaking down, which helps maintain metabolism and prevents the body from slowing down fat loss.
What the research says
1 studyWhen overweight women ate more protein and lifted weights while cutting calories, their appetite hormone leptin went down. Adding a 10-hour eating window didn’t make leptin drop any further than protein alone.
