Satiety: Protein and Eating Speed

• Increasing protein to 30% of calories reduced spontaneous intake and body weight without deliberate restriction.
• Eating more slowly reduced meal intake, although reported hunger did not change.
• Satiety is one of the mechanisms through which high protein makes adherence to a calorie deficit easier.

When logs indicate high hunger, the coach suggests adding protein and fiber to the next meal before cutting calories further.

Adults looking to manage hunger during a calorie deficit.

Modest average effects; individual responses to eating pace vary.

• Protein and Training AdaptationSufficient protein can support gains in lean mass and strength alongside training; the response varies and does not increase indefinitely with higher intakes.
• Higher Protein Intake During a Calorie DeficitIn a deficit, higher protein protects lean mass and can even allow muscle gain alongside intense training; the effective range rises to approximately 1.6 to 2.4 g/kg.
• Rate of weight lossLosing weight slowly, at around 0.5 to 1% of body weight per week, better preserves lean mass, strength, and metabolic rate compared to rapid weight loss.
• Distribute protein throughout the dayDividing protein into servings of around 0.4 g/kg across four or more meals stimulates protein synthesis more than concentrating everything into one or two.
