SR | Little to no impact of low glycemic index/glycemic load diets on weight loss in overweight or obese individuals
30 Jun, 2023 | 14:54h | UTCSummary: This systematic review examined the impact of low glycaemic index or load (GI/GL) diets on weight loss in overweight or obese individuals, analyzing data from 10 randomized controlled trials (RCTs), with 1,210 participants. The main outcomes included changes in body weight, body mass index (BMI), adverse events, health-related quality of life, and mortality. The study showed that low GI/GL diets probably result in little to no difference in body weight and BMI changes compared to higher GI/GL diets or other diets. The evidence suggests a lack of effect on all main outcomes and the possible positive influence on mood remains uncertain.
The studies included in this review had a small sample size with a moderate to very low certainty of evidence. This suggests more well-structured studies with larger sample sizes are needed for firmer conclusions. Limitations of this review included the risk of bias, as many of the studies did not adopt objective outcome measurements and some had a high degree of loss to follow-up. Furthermore, the researchers recommend that future studies focus on diverse demographic groups and include participants from low- and middle-income countries.
Phase 2 RCT | Triple-hormone-receptor (GIP, GLP-1, and glucagon) agonist Retatrutide substantially reduces body weight in obesity
28 Jun, 2023 | 13:23h | UTCSummary: This Phase 2, double-blind, randomized, placebo-controlled trial evaluated the efficacy and safety of Retatrutide, a triple-hormone-receptor agonist of GIP, GLP-1, and glucagon, for obesity treatment. The study recruited 338 adults, predominantly male, with a Body Mass Index (BMI) of 30 or higher, or 27 to 30 with at least one weight-related condition. Participants were administered subcutaneous Retatrutide at varying doses or a placebo, once weekly for 48 weeks.
The findings indicate a dose-dependent weight loss efficacy for Retatrutide. At 24 weeks, Retatrutide users exhibited a mean body weight decrease ranging from 7.2% (1 mg dose) to 17.5% (12 mg dose), compared to a 1.6% reduction in the placebo group. This effect was even more pronounced at 48 weeks, with changes ranging from 8.7% (1 mg dose) to a striking 24.2% (12 mg dose), contrasted with a 2.1% reduction in the placebo group. Adverse events, primarily gastrointestinal, were common with Retatrutide, reported by 73 to 94% of patients, and were dose-related.
Retatrutide demonstrated substantial body weight reduction in adults with obesity, with a side effects profile similar to existing GLP-1 and GIP–GLP-1 receptor agonists. These promising results warrant further investigation through a Phase 3 trial to further ascertain the safety and efficacy of Retatrutide in obesity treatment.

Phase 2 RCT | Triple receptor agonist (GIP, GLP-1 and glucagon) Retatrutide shows promising results in obese patients with T2DM
28 Jun, 2023 | 13:21h | UTCSummary: A Phase 2 Randomized Clinical Trial (RCT) was conducted to investigate the efficacy and safety of Retatrutide, a glucose-dependent insulinotropic polypeptide (GIP), GLP-1, and glucagon receptor agonist, in patients with type 2 diabetes. The study involved 281 adults aged between 18 and 75 years with type 2 diabetes. These patients, with a mean HbA1c level of 8·3%, a mean BMI of 35·0 kg/m², and a mean body weight of 98·2 kg, were randomized to Retatrutide at various doses, Dulaglutide 1.5 mg, and placebo. Patients were treated with diet and exercise alone or a stable dose of metformin for at least three months prior to the study.
The primary outcomes revealed that at 24 weeks, participants who received the higher doses of Retatrutide demonstrated substantial improvements in HbA1c compared to the placebo group and those who received Dulaglutide. Specifically, for the highest-dose Retatrutide group (12 mg), HbA1c level was reduced by an average of 2.02%, which was significantly greater compared to a reduction of 0.01% in the placebo group and 1.41% in the Dulaglutide group.
Regarding body weight, at 36 weeks, participants receiving the different doses of Retatrutide showed a dose-dependent decrease: 3.19% for the 0.5 mg group, 7.92% for the 4 mg escalation group, 10.37% for the 4 mg group, 16.81% for the 8 mg slow escalation group, 16.34% for the 8 mg fast escalation group, and 16.94% for the 12 mg escalation group. This was significantly higher compared to the 3.00% weight loss in the placebo group and the 2.02% loss with 1.5 mg Dulaglutide.
Mild-to-moderate gastrointestinal adverse events were reported among 35% of the participants in the Retatrutide groups, similar to those in the Dulaglutide group, and no severe hypoglycemia or deaths were reported.
The implications of these findings suggest that Retatrutide provides clinically meaningful improvements in glycaemic control and bodyweight reduction with a safety profile consistent with GLP-1 receptor agonists and GIP and GLP-1 receptor agonists. Limitations of the study include limitation of this study is the relatively short duration of the trial and small sample size. Long-term effects and safety of Retatrutide remain to be evaluated in further studies.

Phase 2 RCT | Orforglipron, an oral GLP-1 receptor agonist, significantly reduces weight in adults with obesity
26 Jun, 2023 | 00:58h | UTCSummary: The article reports a phase 2, randomized, double-blind trial investigating the efficacy of the GLP-1 receptor agonist, orforglipron, as an oral weight loss treatment for adults with obesity or overweight plus at least one weight-related condition. The study involved 272 participants, who were administered orforglipron at varying doses or a placebo over a 36-week period.
The key findings of the study indicated significant weight reduction in individuals who were administered orforglipron. At 26 weeks, weight changes in the orforglipron group ranged from -8.6% to -12.6% compared to -2.0% in the placebo group. At 36 weeks, these figures were -9.4% to -14.7% for the orforglipron group and -2.3% for the placebo group. Furthermore, 46-75% of orforglipron recipients experienced a weight reduction of at least 10% by week 36, compared to 9% in the placebo group.
Improvements were also observed in all prespecified weight-related and cardiometabolic measures among orforglipron users. However, the treatment was associated with some mild to moderate gastrointestinal side effects, leading to discontinuation in 10-17% of participants. The safety profile was in line with other GLP-1 receptor agonists. These findings suggest that orforglipron could potentially be an effective oral treatment for weight reduction in adults with obesity, though further research is needed to corroborate these results and assess long-term effects.
