The main purpose of the present study is to perform a 10 weeks dietary intervention study with a follow-up for 52 weeks in children from 7-14 years of age with overweight or obesity. In a caloric restricted and increased physical activity setting the control group will consume a low-moderate protein (15E%/day) diet whereas the intervention group will consume a higher protein (25E%/day) diet. Secondary, the investigators want to investigate the effect of frequent follow-up after the intervention, and the overall effect of the lifestyle camp. Compared to the low-moderate protein diet, the investigators hypothesis that a diet with higher consumption of protein-containing foods will more effectively induce weight loss (a reduction in BMI-SDS) or weight maintenance in children with overweight or obesity, and improve quality of life, and risk factors for type 2 diabetes.
The study will be performed in collaboration with the staff of the well-established multi-component-overnight camps (Julemærkehjem) in Denmark. The multi-component-overnight camps are intensive weight loss camps to which Danish schoolchildren, from 7-14 years of age, are referred to for 10-weeks intervention focusing on healthy lifestyle, healthy eating, new habits and increased physical activity. The primary outcome is anthropometry (BMI-SDS, fat mass, fat-free mass). Secondary outcomes are metabolic health and questionnaires investigating quality of life, eating behavior traits, eating habits and eating-related problems i.e., overeating and loss of control eating. The children will be measured at baseline, 10-weeks and at a 52-weeks follow-up visit. Furthermore, participants will be invited to follow-up visits 3 years, 5 years, 7 years and 10 years, respectively.

In a caloric restricted and increased physical activity setting, the participants will be served a higher protein (25E%/day) diet.
Both the control-group and the intervention-group were offered an increased follow-up contact after camp.
In a caloric restricted and increased physical activity setting, the participants will be served a low-moderate protein (15E%/day) diet.
