Interventions
|
One-day clinical investigation examining responses to high fat test meal in lean and obese subjects followed by randomised, parallel, two-arm, open label, 10-week dietary intervention of two hypo-energetic diets with high and low fat content respectively in obese subjects.
Patients are randomised to receive two hypo-energetic diets with low-fat or high fat content.
