Nuances and limitations in the protein-satiety research.
What the evidence says
- Effects are modest but consistent across studies1
- Long-term success depends heavily on dietary compliance1
- Diet-induced thermogenesis values (5-15% of daily expenditure) vary with diet composition2
- Context matters: values higher with high protein/alcohol consumption, lower with high fat consumption2
- Habitual exposure to a higher-protein diet may diminish its effect on satiety, though other evidence suggests the greater satiating effect is relatively long-lasting3
- No protein-induced adverse effects on net bone balance or calcium balance in young adults or elderly — protein actually increases bone mineral mass and reduces osteoporotic fracture incidence4
- During weight loss, adequate nitrogen intake positively affects calcium balance and preserves bone mineral content4
