Six‐ and Twelve‐Month Changes in Body Composition and 24‐h Energy Expenditure After a Very Low‐Calorie Ketogenic Diet
Authors' conclusion
These findings provide novel insight into the physiological adaptations following VLCKD
Study context
- Population
- Women with obesity who completed a 1-month very low-calorie ketogenic diet (VLCKD)
- Participants
- 17 women
- Outcome
- Body composition (DXA) and 24hEE (whole-room indirect calorimeter)
- Follow-up
- 6 and 12 months
Main finding
As reported in the abstract
6 and 12 months
- Body weight change at 6 months, after initial 7% weight loss
- −3.9%, p < 0.05
- Fat mass change at 6 months
- −10%, p < 0.05
- Minute-by-minute 24hEE trajectories: significant increase in metabolic rate from 1 to 6 months
- p < 0.001
Observational data: associations, not effects.
