Summary: In overweight prediabetic individuals, GOS milk supplemented with mulberry leaf and corn silk extracts significantly reduced 1-hour postprandial glucose, maximum glucose levels, and overall 2-hour glucose excursion compared to pure milk, though it was associated with no reported side effects. PICO Description Population Prediabetic adult individuals (n=11), including a subgroup of overweight participants. Intervention Milk-based interventions containing mulberry leaf and corn silk extracts, particularly galacto-oligosaccharide (GOS) milk supplemented with these extracts. Comparison Pure milk, lactose-hydrolyzed milk, and lactose-hydrolyzed milk with mulberry leaf, corn silk, and resistant dextrin. Outcome In the overweight subgroup, GOS milk with mulberry and corn silk…

The Swedish Obese Subjects (SOS) study demonstrated that bariatric surgery is associated with a 29% reduction in adjusted all-cause mortality compared with conventional obesity treatment over an average 10.9 years of follow-up, with reductions in both cardiovascular and cancer deaths, providing the first prospective controlled evidence for the long-term survival benefit of surgical weight loss.
The Look AHEAD trial demonstrated that intensive lifestyle intervention targeting weight loss in overweight or obese adults with type 2 diabetes did not reduce cardiovascular events over 9.6 years despite clear differences in weight, fitness, and glycaemic control, establishing a critical negative result that informed the rationale for pharmacological obesity treatment with greater weight loss efficacy.
The SCALE trial established liraglutide 3.0 mg as the first GLP-1 receptor agonist approved for chronic weight management, demonstrating a mean weight reduction of 8.0% versus 2.6% with placebo and a 79% reduction in progression from prediabetes to type 2 diabetes in a 160-week extension analysis, setting the clinical and regulatory template for GLP-1 receptor agonist obesity pharmacotherapy.
The SELECT trial demonstrated that semaglutide 2.4 mg reduces 3-point MACE by 20% in overweight or obese adults with pre-existing cardiovascular disease and no diabetes, becoming the first obesity pharmacotherapy trial to demonstrate a hard cardiovascular endpoint benefit and establishing GLP-1 receptor agonism as a cardiovascular intervention in non-diabetic obesity.
SURMOUNT-1 demonstrated that tirzepatide, a dual GIP/GLP-1 receptor agonist, produces dose-dependent mean weight reductions of 15.0–20.9% in adults with obesity without type 2 diabetes, with 57% of participants at the 15 mg dose losing 20% or more of body weight, setting a new pharmacological efficacy benchmark comparable in magnitude to bariatric surgery outcomes.
STEP 1 demonstrated that once-weekly semaglutide 2.4 mg produced a mean weight reduction of 14.9% compared with 2.4% with placebo in adults with obesity without type 2 diabetes, with a third of participants losing more than 20% of body weight, setting a new benchmark for pharmacological weight management and preceding the cardiovascular outcomes evidence from SELECT.
The REWIND trial demonstrated that dulaglutide reduces 3-point MACE in a broad type 2 diabetes population of which 69% had no established cardiovascular disease, with a significant 24% reduction in nonfatal stroke and consistent renal benefit, extending GLP-1 receptor agonist cardiovascular protection into a primary prevention context.
The SUSTAIN-6 trial demonstrated that once-weekly semaglutide reduced 3-point MACE by 26% in high-cardiovascular-risk type 2 diabetes, driven primarily by a significant 39% reduction in nonfatal stroke, while identifying a retinopathy complication signal attributable to rapid glucose lowering in patients with pre-existing retinopathy.
The LEADER trial demonstrated that liraglutide significantly reduced 3-point MACE and cardiovascular mortality in patients with type 2 diabetes and high cardiovascular risk, becoming the first GLP-1 receptor agonist CVOT to demonstrate superiority and characterising an atherosclerotic rather than heart failure protection profile distinct from SGLT2 inhibitors.
