The protective association between plant-based diets and weight loss is weaker or absent in individuals with existing obesity compared to those with normal or overweight status.
If you have obesity, you may find weight loss more challenging with plant-based diets due to metabolic factors like insulin resistance. However, focusing on healthful plant foods remains important for overall health and may still support weight management, even if the effect is less pronounced than in non-obese individuals.
the PDI was inversely associated with weight change among individuals who had normal weight or overweight at baseline, but positively associated with weight change among individuals with obesity.
Why this rating

- Initial treatment for type 2 diabetes should be a combination of metformin and either an SGLT-2 inhibitor or a GLP-1 receptor agonist to achieve cardiorenal protection, rather than monotherapy or older agents like sulfonylureas.Strong
- For patients with specific monogenic obesity syndromes (leptin deficiency, POMC/PCSK1/LEPR mutations), targeted pharmacotherapy (recombinant leptin or setmelanotide) is highly effective and should be prioritized, unlike in polygenic obesity.Strong
- Continued weekly administration of 2.4 mg subcutaneous semaglutide prevents weight regain and promotes further weight loss in adults with overweight or obesity, whereas switching to placebo results in significant weight regain.Strong
