The GLP Mistake Everyone’s Making

Dosing, Safety, and the Metabolic Blueprint Your Doctor Won’t Explain

In this episode, Dr. Matt Chalmers addresses the most pressing questions he receives about GLP medications—and reveals why so many people are using them incorrectly. From dosing mistakes that amplify side effects to dangerous drug interactions and critical nutrient deficiencies, Dr. Chalmers breaks down the complete metabolic picture that most providers aren’t discussing.

He covers everything you need to know about safely using GLPs, including how your medications need to change as your body transforms, why cardio isn’t optional, and the often-overlooked nutritional strategy that separates successful outcomes from health complications. If you’re considering GLPs or already using them, this episode provides the comprehensive framework for maximizing benefits while protecting your long-term health.

1. GLP Medication Administration & Dosing

Dr. Chalmers emphasizes that the most critical issue he sees is people taking GLP medications once weekly, which he considers problematic. He advocates for daily dosing as the optimal approach to reduce side effects and maximize benefits. He recommends gradually titrating up to find the right dose and working with a healthcare provider.

2. Safety Considerations with GLPs

Several safety factors are highlighted:

• Blood pressure monitoring: Blood pressure typically regulates within 3 weeks, so medications may need adjustment to avoid hypotension
• Blood sugar medications: Metformin and other diabetes drugs may need reassessment
• Drug interactions: All medications should be re-evaluated while on GLPs, especially as weight loss occurs
• Weight-based dosing: Most medications are weight-dependent, so dosages need adjustment as patients lose weight

3. Nutrition & Nutrient Deficiencies

A major theme is that the body doesn’t run on calories but on specific nutrients. Dr. Chalmers stresses that:

• Nutrient deficiencies cause muscle loss, liver issues, fatigue, and other complications
• Proper supplementation is essential while using GLPs
• Without adequate nutrients, patients experience poor results and health problems

4. Cardio Exercise & Cardiovascular Health

GLPs are not a replacement for cardio. Key points include:

• Cardio is essential for heart and brain health, not just weight loss
• Cardiovascular fitness is measured by resting heart rate, oxygen saturation, and breathing rate
• Combining weight training with cardio is optimal
• Both steady-state cardio and HIIT are effective

5. Testosterone & Hormonal Function

Testosterone is described as critical when using GLPs. The discussion touches on concerns about heart thickening with testosterone and GLP use, but Dr. Chalmers explains this is normal in athletes and shouldn’t be a concern if cardiovascular markers are healthy.

6. Metabolic Chemistry & Fat Loss

Insulin resistance must be minimized to enable fat burning

Growth hormone is crucial for using fat as fuel

Diet composition (macros, glycemic function) matters more than calorie counting

Fasted cardio combined with proper diet optimizes fat utilization

7. Carbohydrate Management & Resistant Starch

Dr. Chalmers discusses how body type affects carbohydrate needs and introduces the concept of resistant starch (like refrigerated rice) as a beneficial alternative that produces short-chain fatty acids rather than glucose.

The overarching message is that GLP use requires comprehensive metabolic management including proper dosing, medication adjustments, nutrition, exercise, and hormonal monitoring—areas where he feels many providers are falling short.
