In animal models, omega-3 supplementation prevents the development of insulin resistance and obesity by activating PPARα, AMPK, and reducing endocannabinoid tone, mechanisms that are less effective or absent in humans.
This node explains why animal studies often look better than human trials: mice process omega-3s differently (more peroxisome activation) than humans. This is a mechanistic insight, not a direct human protocol.
GoodSupportsHIGH confidence
In rodents, activation of PPARα stimulates formation of peroxisomes much more than in humans... reflecting the major differences in the PPARα species... consistent with a very weak or non-existent anti-obesity effect of omega-3 in humans
Why this rating
Based on mechanistic studies in mice.

- 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
