Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The study will be conducted as a parallel randomized controlled intervention trial, initiated by eight weeks rapid weight loss with one of two VLCDs, one week of reintroducing regular foods, and 12 weeks with one of two different ad libitum diets; in total 21 weeks. The study will be blinded for the statistician. Due to obvious different dietary intakes in the two diets, subjects cannot be blinded and neither the study personnel. As the study includes different dietary recommendations the registered clinical dietician advising the subjects cannot be blinded either.

In total 110 overweight and obese volunteers will be included.

Group Type ACTIVE_COMPARATOR

Maintenance-Control

Intervention Type OTHER

Weight loss maintenance diet with moderate protein and low glycemic index and load, high in fiber and whole grain, daily including 25 g minced beef.

Maintenance-Active

12-week weight maintenance diets: High protein weight maintenance diet (HP-WMD): The macronutrient distribution will be 25 energy percentage (E%) from protein, 45 E% from carbohydrate and 30 E% from fat. The diet will include 150 g beef as a daily source of protein, The diet is ad libitum and will be high in fibre (40 g/10 MJ) and whole grain (150 g/day) and allow inclusion of free/added sugar up to the recommended level (\<10E% sugar).
