For anyone using — or considering — a GLP-1 medication
The medication handles your appetite.
Who's handling everything else?
GLP-1 medications can produce remarkable weight loss. But losing weight fast and losing weight well are not the same thing. Your muscle, your nutrients, how you tolerate the transition, and what happens when you eventually stop — that's where lasting results are made or lost. This is the physician-built nutrition side of the equation.
Guided by Dr. Michael Fitzmaurice, MD — physician, exercise physiologist, and fellowship-trained in longevity & regenerative medicine.

These medications are a powerful tool. But the number on the scale doesn't tell you what you're losing — and for many people, no one is watching the parts that matter most for staying healthy and keeping the weight off.
Muscle can leave with the fat
When intake drops quickly, a meaningful share of the weight lost can come from lean muscle — not just fat — unless protein and resistance training are deliberately prioritized. Muscle is what keeps your metabolism strong and your body functional.
Eating less means fewer nutrients
Smaller appetite means smaller meals — and smaller meals can quietly fall short on the protein, vitamins, and minerals your body still needs every day. What you eat matters more now, not less, precisely because there's less of it.
Nausea derails good intentions
Common early side effects can make eating unappealing right when nutrition matters most. A tolerance-first eating strategy helps you meet your needs without fighting your stomach.
And then — what happens when you stop?
The habits, muscle, and metabolic foundation you build during treatment are what carry your results forward afterward. Building that foundation is nutrition and lifestyle work — and it's the part worth getting right from day one. (Any decisions about the medication itself belong with your prescriber.)
Four things that decide whether your results last
The medication is one piece. These are the four you actually control.
| 01 |
Protect your musclePrioritizing protein and resistance training helps you lose fat while holding on to the lean mass that keeps your metabolism working for you. |
| 02 |
Cover your nutrientsEating less makes nutrient density non-negotiable. A deliberate approach helps you meet your needs even on a shrinking appetite. |
| 03 |
Eat for toleranceFood choices and timing that work with the medication's effects — so you can stay nourished without triggering the nausea that makes people undereat. |
| 04 |
Plan for afterThe habits and metabolic foundation you build now are what protect your results down the road. This is where a plan beats hoping for the best. |

Common questions
Will I lose muscle on a GLP-1 medication?
Some lean-mass loss can accompany rapid weight loss when protein intake and resistance training aren't prioritized. That's exactly why a deliberate muscle-protection strategy matters — and it's a central focus of the consultation and the guidance here.
What should I eat while on these medications?
With a smaller appetite, the priority shifts to protein-forward, nutrient-dense meals that are easy to tolerate. The right approach is individual, which is what a consultation is designed to work out with you.
What happens when I stop the medication?
The muscle, habits, and metabolic foundation you build during treatment are what help carry your results forward. Building that foundation is nutrition and lifestyle work. Any decision about starting, adjusting, or stopping the medication itself belongs with your prescribing physician.
Is this a replacement for my medication?
No. This is the nutrition and lifestyle companion to your treatment — not an alternative to it. We focus on what you eat and how you live so the medication can do its job and your results can last. Talk to your prescriber about the medication itself.
Can Dr. Fitz prescribe or adjust my GLP-1?
Consultations here are focused on metabolic education, nutrition, and lifestyle strategy. Prescribing and dosing decisions stay between you and your own prescribing physician.
