7 Ozempic-like drugs may reduce addiction cravings by targeting brain's 'craving center'¶
GLP-1 drugs like Ozempic and Wegovy, originally developed for diabetes and weight loss, appear to reduce cravings for alcohol and addictive substances by acting on the lateral septum, a brain region connecting memory and reward. Human studies confirm reduced alcohol consumption; animal studies show reduced use of cocaine, amphetamines, opiates, and nicotine.
- GLP-1 drugs reduce cravings for alcohol, cocaine, amphetamines, opiates, and nicotine
- Mechanism operates through lateral septum, a brain region densely packed with GLP-1 receptors
- Lateral septum acts as neural control point between thinking about rewards and pursuing them
- Could open new therapeutic approaches to addiction treatment

6.5 Ketogenic Diet Improves Exercise Response in High Blood Sugar, Study Finds¶
A study by exercise scientist Sarah Lessard demonstrates that a high-fat, low-carbohydrate diet can restore the metabolic benefits of exercise in mice with hyperglycemia.
- Study published Feb. 25 in Nature Communications by Sarah Lessard at Virginia Tech's Fralin Biomedical Research Institute
- Mice on ketogenic diet normalized blood sugar within one week
- Diet caused muscle remodeling, increasing oxidative fibers and aerobic exercise response
- High blood sugar normally impairs muscles' ability to increase oxygen uptake during exercise; ketogenic diet counteracted this effect
