Adherence

Bariatric surgery alters food preference and hedonic response, reducing the appeal of high-calorie, high-sugar foods and increasing preference for low-fat foods, which contributes to sustained weight loss.

After surgery, your brain's reward system for food changes. You may naturally find high-sugar and high-fat foods less appealing, which helps you stick to a healthier diet. This is a biological shift, not just willpower.

Late after surgery, these animals exhibit a change in preference from a high-fat, high-sugar diet to a normal chow diet... RYGB leads to a shift in hedonic evaluation, favouring low- over high-calorie foods and restores obesity-induced alterations in ‘liking’ and ‘wanting’.
