Frequently asked questions

Will I gain the weight back when I stop taking my GLP-1 medication?

This is the #1 fear — and it's valid. Research shows that most people do regain a significant portion of lost weight after stopping GLP-1 medications because the drug was suppressing appetite signals, not rebuilding the cellular foundation that supports a healthy metabolism. That's exactly why what you do while on the medication matters so much. My GLP-1 coaching program focuses on rebuilding your cellular health — including your glutathione levels and protein intake — so your body has the biological foundation it needs for lasting results, with or without the medication

What should I eat while on a GLP-1? I have no appetite and I'm barely eating

When your appetite is suppressed, every bite has to count — there's simply no room for empty calories. Most GLP-1 coaches and physicians recommend prioritizing lean, high-quality protein above everything else, typically 60–80 grams per day at minimum, to protect muscle and support healing. The challenge is that most people can only manage small amounts of food, so the protein has to be easy to consume and highly bioavailable. That's one reason Immunocal® powder works so well for GLP-1 clients — it dissolves easily, has no strong flavour, and delivers a clinically unique form of protein that your body absorbs efficiently even when you're eating very little. My 30-Day Reboot program is built around exactly this nutritional strategy.

I'm losing weight but also losing muscle. What can I do about it?

Muscle loss is one of the most significant and underreported concerns with GLP-1 medications. Because these drugs suppress appetite dramatically, most people aren't eating nearly enough protein to protect lean muscle — and that accelerates the very aging process they're trying to reverse. The solution starts with two things: adequate protein intake and cellular-level support. Immunocal® is a clinically studied whey protein isolate that helps your body produce glutathione, your master antioxidant, while delivering the bioavailable protein your muscles need. I recommend it to every GLP-1 client as a non-negotiable foundation. [Learn more about Immunocal® here →]

Are there natural supplements that support or enhance GLP-1 results?

Yes — and the most important one most people have never heard of is glutathione. Glutathione is your body's master antioxidant and detoxifier, and after 40, your body produces less of it naturally. When you're losing weight rapidly — as many people do on GLP-1 medications — your cells are working hard, and oxidative stress increases. Supporting your glutathione levels during this process helps your cells recover, your immune system stay strong, and your energy stay more stable. Immunocal® is the only natural health product with a patented formula clinically shown to help raise and sustain glutathione levels in the body. As a Certified GLP-1 Coach, I use it as a cornerstone of every client protocol. Book a Discovery Call to learn how →

How long will I need to stay on GLP-1 medication?

Physicians generally consider GLP-1 medications a long-term treatment, much like blood pressure medication — obesity is a chronic condition and the effects of the drug tend to wane once you stop. However, the goal of good GLP-1 coaching isn't just to manage the medication — it's to use the window the medication creates to rebuild healthy habits at the cellular level, so you have the best possible outcome whether you stay on it or eventually transition off. My Vitality180 program was designed for exactly this: 90 days of structured support to help your body become healthier from the inside out while the medication is doing its work.

Why am I so exhausted on my GLP-1 medication — and what can I do about it?

Fatigue is one of the most common complaints GLP-1 users bring up, and it makes complete sense once you understand what's happening at the cellular level. When you're eating significantly less, your body is getting fewer of the raw materials it needs to produce energy — including the nutrients required to support mitochondrial function and your natural antioxidant defences. At the same time, rapid fat metabolism increases oxidative stress, which depletes glutathione — your body's master antioxidant and one of the key players in cellular energy production.

This is the gap most GLP-1 programs completely overlook. Supporting your glutathione levels while you're on the medication isn't a nice-to-have — it's foundational to how you feel day to day. Immunocal® is a clinically studied whey protein isolate that helps your body replenish the glutathione it makes less of after 40, while also delivering the bioavailable protein your muscles and metabolism depend on.

Why is my hair falling out on GLP-1 — and is there anything I can do?

Hair loss on GLP-1 medications is far more common than most people are warned about — and it catches women especially off guard. The culprit is a condition called telogen effluvium, where the physical stress of rapid weight loss and dramatically reduced calorie intake shocks the hair follicle cycle, pushing more hairs into the shedding phase at once. It typically shows up 2–4 months after starting the medication, which makes it easy to miss the connection.

The root cause comes back to two things: inadequate protein and increased oxidative stress at the cellular level. Your hair follicles are among the most protein-hungry structures in your body, and when you're barely eating, they're the first to be deprioritized. At the same time, the cellular stress of rapid fat metabolism depletes glutathione — your body's master antioxidant — which plays a direct role in protecting the follicle environment.

This is exactly why nutrition support during GLP-1 therapy isn't optional. Prioritizing high-quality, bioavailable protein every single day — and supporting your glutathione levels — gives your body what it needs to protect your hair alongside everything else it's rebuilding. For many of my clients, adding Immunocal® as a daily foundation made a noticeable difference in how they felt and looked during their transformation.
