| Scientific title | Genetic Polymorphisms and Weight Loss in Obesity: A Randomised Trial of Hypo-Energetic High- versus Low-Fat Diets |
| Study acronym | NUGENOB |
| Study objectives | There is an interaction between nutrient composition of the diet - more specifically the fat content - and obesity-related genes in the response to dietary treatment of human obesity. |
| Ethics approval(s) | The study has received appropriate ethics committee approval. Denmark reference number: 01-083/01, 6/07/2001. The Netherlands: reference number: 01-058.3, 27/04/2001. Sweden: reference number: 127/01, 7/05/2001. United Kingdom reference number: GM040103, 14/05/2001. Czech Republic: 12/06/2001. France: reference number: 2-01-12/2, 30/03/2001. Spain: 5/04/2001. |
| Health condition(s) or problem(s) studied | Obesity |
| Intervention | 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. |
| Intervention type | Other |
| Primary outcome measure | Weight loss |
| Secondary outcome measures | 1. Changes in waist circumference 2. Body composition assessed by bio-impedance 3. Fasting blood lipids 4. Insulin and glucose |
