Self-reported increases in sweet and salty taste perception during GLP-1 or dual GIP/GLP-1 receptor agonist therapy are significantly associated with increased satiety, reduced appetite, and reduced food craving.
If you are taking a GLP-1 medication and notice your taste has changed (e.g., sweets taste stronger or saltier), this is a common and potentially helpful side effect. The research suggests these sensory changes are linked to feeling fuller faster and having fewer cravings, which supports your weight loss efforts. Do not be alarmed by these changes; they may be part of how the medication helps regulate your appetite.
Independent of the type of therapy, increased sweet taste perception was significantly associated with increased satiety (adjusted odds ratios [AOR] = 2.02; 95% CI: 1.15–4.57), decreased appetite (AOR = 1.67; 95% CI: 1.04–3.25) and decreased craving (AOR = 1.85; 95% CI: 1.05–3.29). Increased salty taste perception was associated with increased satiety (AOR = 2.17; 95% CI: 1.16–5.17; all p < 0.05).
Why this rating
Cross-sectional observational study with self-reported data; associations are significant but causality cannot be established.

- 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
