The drug reference side of GLP Dex covers what these medications are, how they work, and what the trial data shows. This is the other side — what it's actually like to be on one, and what you can do to get the most out of it.
GLP-1 drugs are tools. The medication creates the calorie deficit and quiets the food noise. What happens inside that window — what you eat, whether you lift, how you sleep, how you manage early side effects — determines the quality of the outcome.
These posts are distilled from clinician content, patient community data, and the research behind both. Written for people who are on a GLP-1 drug or seriously considering one.
Nutrition and body composition
What to Eat on GLP-1s
The foods that fight the drug vs. the foods that work with it. The avoid list has clear mechanisms behind it — red meat early on, artificial sweeteners, raw cruciferous vegetables — and the protein priority is the single most important nutritional shift.
Muscle Loss on GLP-1s
The most repeated concern is also the most misunderstood. What the research says about fat-free mass vs. skeletal muscle, the 25% benchmark, complete vs. incomplete protein, and what resistance training does that nothing else does.
Exercise on GLP-1s
Resistance training first, cardio second — and why the order matters. How to train while appetite-suppressed, what body recomposition actually requires, and how to start if you've never lifted before.
Side effects and symptoms
GLP-1 Side Effects, Explained
Nausea, constipation, reflux, diarrhea, fatigue, insomnia — what causes each, when it resolves, what to do when it doesn't. Why tirzepatide is often better tolerated than semaglutide for nausea, and which symptoms are warning signs.
Hair Loss on GLP-1s
Telogen effluvium explained — why rapid weight loss triggers shedding, why it's delayed three months, what ferritin levels have to do with it, and why biotin supplements almost certainly won't help.
Sleep on GLP-1s
Poor sleep raises ghrelin and suppresses leptin, creating hormonal headwinds the drug has to fight. What GLP-1s do to sleep architecture early in therapy, the SURMOUNT-OSA sleep apnea data, and what actually improves sleep while on the drug.
Mental and behavioral effects
Food Noise and Mental Health on GLP-1s
The quieting of food noise is GLP-1 receptor agonism in the brain's reward circuit — not willpower. Why the effect extends beyond food to alcohol, gambling, and compulsive behaviors. The depression risk clarified, and the anhedonia edge case explained.
Alcohol on GLP-1s
Tolerance drops, taste changes, and many people stop drinking without trying to. The mechanism behind each, the pancreatitis risk, and what to do if you still drink.
Long-term strategy
Dosing Strategy on GLP-1s
The standard titration schedule is a starting point. When to hold, when to escalate, what wrong-dose looks like in both directions, what microdosing actually is, and how maintenance dosing differs from weight loss dosing.
Coming Off GLP-1s
Most people who stop regain the weight — that's pharmacology, not failure. SURMOUNT-4 data on rebound, why the body defends its previous set point, the maintenance dose option, and what habits need to be in place before stopping.
