Your GLP1 Companion Guide

The Functional Health Guide to Staying Healthy on GLP1/GIP and Keeping Results After

Your medication is handling appetite. It isn't handling your gut, muscle, blood sugar, nutrient levels, or mind, and those are exactly the things that decide whether you feel good on this medication, or just smaller.

Who This Guide Is For

Curious Before You Commit

You’re weighing whether to start a GLP1 or GIP medication and want to know what to expect, and what to do about it, before you decide.

Worried About the Rebound

You’ve heard what can happen when people come off these medications. You want to build something that lasts, not just lose the weight and gain it back.

Already On It, Something Feels Off

Constipation, nausea, low energy, a flatter mood than usual. You suspect it’s more than “just the medication,” and you’re right.

Just Starting Out

You’re new to GLP1 or GIP therapy and want to do it right from day one, not learn the hard way.

Tired of Generic Advice

You’ve read the “eat more protein” posts. You want the mechanism, the protocol, and the reasoning behind it.

GLP1 and GIP medications are one of the most effective tools available for weight loss right now, and one of the most misunderstood.

Used well, with the right foundation underneath it, these medications can help you lose weight, keep your energy, protect your muscle, and feel like yourself while it’s happening. Used without that foundation, you’re left managing side effects nobody warned you about, and hoping the results hold once you come off.

This guide closes that gap.

Who’s Behind This

I’m Rachel Leigh, founder of Luxia Coaching. I’m a Functional Nutrition Therapist, a board certified health and wellness coach, an ICF Professional Certified Coach, and a certified hormone specialist, with 30 years studying the human body and 16 years in clinical practice.

I’ve worked directly with more than 1,000 clients, with a specialty in sustainable weight loss and root-cause functional health. My approach has never been about treating one symptom at a time. It’s about looking at your gut, your hormones, your blood sugar, and your stress response as one connected system, because that’s how your body actually works.

Today I bring that same functional, whole-body approach to clients on GLP1 and GIP medications, adapted for exactly what your body needs while you’re on one.
