Adherence

Current standard-of-care structured lifestyle modification (500 kcal deficit + 150 min activity) added to obesity pharmacotherapy lacks evidence of improving drug response and may act as a barrier to care by reinforcing stigma.

If you are starting obesity medication, you do not need to complete a mandatory lifestyle program to access or benefit from it. Current evidence does not show that mandatory calorie counting and exercise improve drug results. Focus on your health and well-being; if you choose to make lifestyle changes, do so for yourself, not as a requirement for your medication.

ModerateRefutesMEDIUM confidence
there is no specific evidence that they improve the response to obesity medications... insisting that patients undertake structured lifestyle modification while on drug therapy, in the absence of any evidence of benefit, could reinforce the view of many healthcare professionals... that obesity arises from poor discipline, motivation or effort.
