Study Overview
Brief Summary
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.
Detailed Description
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.

Arms & Interventions
SARS CoV-group
This group should have been the control group. However, due to the COVID19 lockdown of the camps for 5 five weeks, with no control of diet and physical activity, this group could not act as control group. Therefore, this group has been excluded from longitudinal analyses.
Intervention: Diet with a lower amount of protein (15E% per day) (Dietary Supplement)
Control Group (CG)
Current weight-loss diet (15E%/day protein) for the 10 weeks they attend the camp. Increased follow-up contact after camp.
Intervention: Increased follow-up contact after the 10-week intervention (Behavioral)
Control Group (CG)
Current weight-loss diet (15E%/day protein) for the 10 weeks they attend the camp. Increased follow-up contact after camp.
Intervention: Diet with a lower amount of protein (15E% per day) (Dietary Supplement)
Intervention group (IG)
A higher protein diet (25E%/day) for the 10 weeks they attend the camp. Increased follow-up contact after camp.
Intervention: Diet with a higher amount of protein (25E% per day) (Dietary Supplement)
Intervention group (IG)
A higher protein diet (25E%/day) for the 10 weeks they attend the camp. Increased follow-up contact after camp.
Intervention: Increased follow-up contact after the 10-week intervention (Behavioral)
Outcomes
Primary Outcomes
Body Mass Index Standard Deviation Score (BMI-SDS)
Time Frame: Mean changes from baseline to 10-weeks (post camp intervention)
BMI-SDS was calculated using World Health Organization Anthro-Plus software.
Body Weight (kg)
Time Frame: Mean changes from baseline to 10-weeks (post camp intervention)
Body weight (kg) was measured in light clothing without shoes using a Bioelectric impedance (InBody model 270, Hopkins Medical Products, Grand Rapids, MI, USA).
Body Fat (%)
Time Frame: Mean changes from baseline to 10-weeks (post camp intervention)
Body fat (%) was measured in light clothing without shoes using a Bioelectric impedance (InBody model 270, Hopkins Medical Products, Grand Rapids, MI, USA).
Skeletal Muscle Mass (kg)
Time Frame: Mean changes from baseline to 10-weeks (post camp intervention)
Skeletal muscle mass (kg) was measured in light clothing without shoes using a Bioelectric impedance (InBody model 270, Hopkins Medical Products, Grand Rapids, MI, USA).
