Excess weight is a major risk factor underlying leading causes of death globally, including cardiovascular disease, type 2 diabetes, and some cancers. Among participants assigned to the same lifestyle intervention arms in prior weight loss randomized controlled trials, large inter-individual differences in weight loss success have been observed, ranging from >50lbs of weight loss to >10lbs of weight gain. Both genetic and non-genetic factors underlying differential adherence and weight loss success are poorly understood.
