GLP-1 physiology informs the pharmacotherapy of obesity

Daniel J. Drucker

Summary: GLP1RA is an effective drug for the treatment of type 2 diabetes and has potential for obesity treatment. GLP-1 reduces food intake and body weight in both animals and humans, and its mechanisms of action have been extensively studied. GLP-1-based therapies may become important options for the treatment of obesity and its complications.

Summary: One year after withdrawal of once-weekly subcutaneous semaglutide 2.4 mg and lifestyle intervention, participants regained two-thirds of their prior weight loss, with similar changes in cardiometabolic variables. Findings confirm the chronicity of obesity and suggest ongoing treatment is required to maintain improvements in weight and health.

Management of type 2 diabetes with the dual GIP/GLP-1 receptor agonist tirzepatide: a systematic review and meta-analysis

Thomas Karagiannis, Ioannis Avgerinos, Aris Liakos, Stefano Del Prato, David R. Matthews, Apostolos Tsapas, Eleni Bekiari

Summary: This study conducted a systematic review and meta-analysis to evaluate the efficacy and safety of tirzepatide for type 2 diabetes. The results showed that tirzepatide had dose-dependent superiority in lowering HbA(1c) and reducing body weight compared to placebo, GLP-1 RAs, and basal insulin. However, tirzepatide was associated with an increased incidence of gastrointestinal adverse events.

Mitochondrial Ferritin Deficiency Promotes Osteoblastic Ferroptosis Via Mitophagy in Type 2 Diabetic Osteoporosis

XinDong Wang, HongDong Ma, Jun Sun, TianYu Zheng, Peng Zhao, HaiTian Li, MaoWei Yang

Summary: The incidence of type 2 diabetic osteoporosis (T2DOP) is rapidly increasing and its specific mechanism remains unclear. Studies have shown a relationship between iron overload and T2DOP. Mitochondrial ferritin (FtMt) may inhibit ferroptosis in osteoblasts by reducing oxidative stress caused by excess ferrous ions, while FtMt deficiency induces mitophagy in the pathogenesis of T2DOP. FtMt could potentially serve as a target for T2DOP therapy.

Summary: Metformin, a commonly used drug for type 2 diabetes, has shown potential therapeutic effects for other diseases such as polycystic ovary syndrome, cancer, and neurodegenerative diseases. However, there is still debate on whether metformin is effective for all diseases and whether its benefits are solely due to its anti-hyperglycemic and insulin-sensitizing effects.

The nutrition transition to a stage of high obesity and noncommunicable disease prevalence dominated by ultra-processed foods is not inevitable

Barry M. Popkin, Shu Wen Ng

Summary: The Nutrition Transition model shows variations in the nature and pace of change in key stages depending on location and subpopulations. Currently, many countries are facing a stage where nutrition-related noncommunicable diseases are dominating adult morbidity and mortality, while some populations still suffer from hunger and undernutrition. By committing to policies that have been shown to improve dietary choices and social norms around foods, countries can prevent or reverse the rapid shift towards diets high in ultra-processed foods and the increasing prevalence of nutrition-related noncommunicable diseases.
