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.
