A year-long observational study in Japan suggests that people with type 2 diabetes who tend to overeat in response to tempting food cues such as sight and smell may see greater weight loss—and possibly better blood-sugar improvement—after starting GLP-1 receptor agonists, while those with primarily emotional eating patterns show less consistent links to long-term outcomes.

Scientists have developed a hybrid obesity treatment that uses GLP-1 and GIP signals to deliver a metabolic enhancer directly into cells. Early tests in mice showed greater weight loss and better blood sugar control than standard therapies. The approach aims to reduce side effects by limiting the drug's action to targeted areas.

A real-world study of nearly 8,000 patients by Cleveland Clinic researchers shows that stopping injectable semaglutide or tirzepatide often does not lead to major weight regain. Many participants maintained or continued losing weight by restarting treatment, switching medications, or using lifestyle support. This differs from clinical trials where rapid regain was observed.

A randomized controlled trial in 180 adults found that prescribing diets high, regular or low in sweet-tasting foods for six months did not change participants’ liking for sweet taste, body weight, energy intake, or several biomarkers linked to diabetes and cardiovascular disease. The researchers concluded the results do not support public health advice that aims to reduce exposure to sweet-tasting foods regardless of whether sweetness comes from sugar, low-calorie sweeteners, fruit or dairy.

Researchers at the University of California, Riverside say they have developed a flexible, battery-powered gel patch that generates oxygen inside hard-to-heal wounds—an approach aimed at countering deep-tissue oxygen deprivation that can stall recovery and contribute to amputations. In experiments in diabetic and older mice, the team reported that wounds that often remained open—and were sometimes fatal—closed in about 23 days when treated with the oxygen-generating patch.

Researchers have identified why living at high altitudes reduces diabetes risk: red blood cells absorb excess glucose in low-oxygen conditions. This metabolic shift lowers blood sugar levels, as shown in mouse experiments. A new drug mimicking this effect reversed diabetes in mice, suggesting potential treatments.
