Dr. Ian Ellis, Founder of voafit.com | Precision Dosing, Peptides, and the Future of Human Performance

The story starts in an emergency room. Dr. Ian Ellis spent almost a decade watching the same patients cycle through with the same problems, receiving the same treatments, never actually getting better. Just bailing out the pool, he says. That disillusionment became the seed of something bigger.

When Dr. Ellis was prescribed semaglutide in 2022, he experienced what millions of people experience every day: real weight loss with a catastrophic tradeoff. Thirty pounds gone. But the body composition scan told the real story. He had lost twice as much lean mass as fat. Same body fat percentage. Just a lighter, weaker version of himself. The drug had done what it was designed to do. The problem was the dosing.

That realization sent him down a research rabbit hole that ended with the founding of his concierge practice and an app called My Level, designed to help patients find their minimum effective dose of GLP-1 medications, not the maximum tolerated dose. The results at his clinic have been remarkable: faster weight loss than clinical trials, on half the medicine, with zero desistance due to side effects.

Key Frameworks:

• The Precision Dosing Model: Standard GLP-1 protocols escalate doses on a fixed schedule regardless of individual response. Dr. Ellis argues this is backwards. The goal is to find the lowest dose that suppresses appetite just enough to create a 500-750 calorie deficit, not to eliminate hunger entirely. Think dimmer switch, not on/off toggle.
• The Appetite-as-Physiology Framework: Willpower is not a weight loss strategy. Dr. Ellis compares appetite suppression to sleep deprivation. You can fight it for a day or two, but biological drives increase in intensity until they become inevitable. The solution is not discipline. It is solving the physiologic problem.
• The Nutrition Hierarchy on GLP-1s: Because appetite is suppressed, what you eat first matters enormously. If you fill up on carbs, you will never reach protein and plants.
• The Cost-Convenience-Quality Triangle: You only get two. Cheap and convenient equals low quality. Convenient and high quality equals expensive. Inexpensive and high quality means you are cooking it yourself. There is no fourth option.
• Peptides as Information Systems: Peptides are strings of amino acids that act as keys for specific biological locks. Their safety profile is relatively predictable because they bind to one receptor and produce effects that follow logically from what that receptor does. GLP-1 receptor? Suppresses appetite and slows gastric motility. Overdose? Stomach stops working. Predictable. Manageable.
• The 15% Body Fat Sweet Spot: Evolutionary biology has calibrated human attraction toward function, not aesthetics. Studies show 15% body fat consistently ranks as most attractive across populations because it signals strength, capability, and survivability. Single-digit body fat is not optimal health. It is a performance liability.
