Controversial Topic: GLP-1's
Glucagon-like peptide-1 (GLP-1) receptor agonists, like Ozempic and Mounjaro, are often prescribed for type 2 diabetes and recently, have been FDA approved for weight loss. These medications are helpful in blood glucose management and weight loss, however they change appetites, food tolerance, and digestive system regulation. There is a lack of nutritional education given to individuals who start these medications and may not fully understand the potential side effects if they do not manage their nutrition well.
Here are several key nutrition recommendations for someone taking a GLP-1 to consider:
1- Protein intake: aim for a minimum of 60 grams per day. Optimal amount would be 1.5 g/kg/day to reduce muscle wasting as weight loss occurs. Space it throughout the day to ensure muscle synthesis.
2- Hydration: aim for 64 oz of water per day. Limit carbonated beverages which may irritate stomach due to delayed gastric emptying caused by the medication.
3 - Fiber: high fiber diet is recommended. Males should get 45 grams per day, females should get 37 grams per day.
4 - Vitamins and minerals: GLP-1 medications disrupt nutrient absorption so watch for signs of nutrient deficiencies, get lab work done routinely, have a dietitian assess diet nutrient adequacy, and supplement when necessary.
