Potential updates in the MNT for adult obesity guidelines based on the latest evidence

Current guideline	Impact of new evidence
Partial meal replacements (replacing one to two meals/day as part of a calorie-restricted intervention) to reduce BW, WC, BP and improve glycaemic control Level 1a, grade B	New evidence in support of the guideline in both Level 2 (n = 3) and level 1 (n = 2) Evidence level to remain unchanged Strength of recommendation could be upgraded to grade A
Intermittent or continuous calorie restriction achieved similar short-term BW reduction Level 2a, grade B	New evidence includes both level 2 (n = 2) and level 1 (n = 5) New level 1 evidence indicates potential superiority of fasting approaches on weight outcomes and lipid profiles, but it is currently inconclusive No evidence to support a superiority in glucose metabolism Closer follow-up of the literature may warrant recommendation update in the near future
