PRE-Pregnancy Weight Loss And the Reducing Effect on CHILDhood Overweight - Copenhagen

Summary

The study is a single site parallel randomized controlled study.

The study will be assessing the effect of approximately 10% weight loss intervention vs a control group among healthy females/couples where the prospective mother is overweight or obese (BMI 27-45 kg/m\^2) and between 18-38 years. The investigators will recruit a total of 240 healthy females/couples who will be randomized 1:1 to either intervention or control, stratified according to maternal pre-pregnancy BMI.

The overall objective is to test whether a comprehensive pre-conceptional parental weight loss intervention effectively reduces the risk of offspring overweight and adiposity and its complications compared to a control group. The investigators hypothesize that parental weight loss intervention, initiated before conception, will facilitate lower parental insulin resistance, inflammation, body weight and adiposity, incretin responses compared to usual care. For the offspring the investigators hypothesize that the intervention will reduce adverse pregnancy outcomes with a reduction in offspring neonatal adiposity, reduced risk of being born large for gestational age (LGA) and with lower BMI z-score at 12 months.

Interventions

BEHAVIORAL

Weight loss intervention

Subjects will receive very low-calorie diet for 8-10 weeks to introduce a rapid weight loss of approximately 10%. Once target weight is achieved, participants will be reintroduced to foods to introduce weight stability. The male will follow the maternal randomization, i.e. weight loss if BMI ≥25 until a BMI of 23 or a weight loss of approximately 10% is obtained. During weight loss maintenance, subjects will receive dietary counseling to follow a diet high in protein (corresponding to 22-25E%), high fiber and wholegrain while fulfilling the requirements for essential fatty acids, micronutrients and trace elements in accordance with Nordic Nutrition Recommendations (NNR) 2012. Throughout the study period participants will be encouraged to follow the official recommendations for physical activity as recommended by the Danish health authorities 2022.
