What should you actually eat on a GLP-1?

Social media is filled with advice about protein, electrolytes, collagen, greens powders, supplements, and "must-follow" nutrition rules. But how much of that advice is actually supported by evidence?

In this episode of Weight & Measure, Zach Niemiec and Mike Donnelly-Boylen are joined by registered dietitians Gianna Beasley, MS, RD, CPT and Melissa Mitri, MS, RD to separate GLP-1 nutrition facts from fiction.

Whether you're taking Zepbound (tirzepatide), Mounjaro, Wegovy (semaglutide), Ozempic, Saxenda, or another obesity management medication, this conversation provides practical, evidence based guidance to help you build healthy, sustainable nutrition habits.

You'll also hear valuable insights for people who have undergone metabolic & bariatric surgery and are using GLP-1 medications.

• The biggest GLP-1 nutrition myths on TikTok, Instagram, Reddit, and Facebook

• Why eating less does not always mean better nutrition

• How much protein do GLP-1 patients really need?

• Electrolytes, collagen, creatine, greens powders, and supplements: what's worth your money?

• Why many patients become afraid of food after starting GLP-1 medications

• Weight loss plateaus: what they really mean

• Why losing weight doesn't automatically mean you're well nourished

• When to work with a registered dietitian

• Nutrition after metabolic & bariatric surgery while taking GLP-1 medications

• What to do if insurance forces you to stop your medication
