Hypothesis
Low protein content in single meals may induce lower values of energy expenditure and fat oxidation as compared to adequate protein content.
Conclusion
Low protein meals resulted in reduced postprandial energy expenditure and increased exogenous fat oxidation compared to adequate protein meals.
Supporting Evidence
- Postprandial energy expenditure was 160 kJ/6 h lower after low protein meals.
- Diet induced thermogenesis increased less after low protein meals compared to adequate protein meals.
- Exogenous fat oxidation was significantly higher after low protein meals.
Takeaway
Eating meals with less protein makes your body use less energy and burn more fat from outside sources.
