Macro partitioning
Post-bariatric surgery success (defined as >50% excess weight loss) is significantly associated with maintaining carbohydrate intake below 173g/day and fat intake below 52.5g/day at 12 months, alongside a total caloric intake under 1523 kcal/day.
After bariatric surgery, hitting your weight loss goals depends heavily on what you eat, not just how much. At one year, aim for less than 1523 calories, keep carbs under 173 grams, and fat under 52.5 grams. Crucially, ensure you are eating more than 86.5 grams of protein daily. This specific balance of macros is what separates successful long-term weight loss from failure.
At 12 months, the cutoff ratio for energy obtained from carbohydrates, protein, and fat was <49.0, >24.5, and <28.0%, respectively... The cutoff calorie intake for success in weight loss was <835.0, <1132.5, and <1523.0 kcal/day at 1, 6, and 12 months post operation, respectively.
Why this rating
Observational retrospective study with a moderate sample size (n=189) and potential for self-reporting bias.
