Why this guide exists

Without a protocol, a quarter to forty percent of every pound you lose on a GLP-1 is muscle, not fat. That loss is permanent — and it's the reason most patients regain within two years.

The medication works. The way it's being prescribed — particularly through discount tele-health and compounded operators — leaves out everything that turns weight loss into healthy weight loss. The seven pages that follow are the playbook.

Pre-flight labs: get these 14 markers before your first dose

Most dispensaries skip baseline labs entirely. You can't measure what's changing if you never measured where you started.

• Comprehensive metabolic panel (CMP)
• Fasting glucose
• HbA1c
• Lipid panel
• Vitamin D (25-OH)
• Vitamin B12
• Magnesium (RBC)
• Ferritin
• hs-CRP (inflammation)
• TSH (thyroid)
• Free T3 / Free T4
• Cortisol (AM)
• Total & free testosterone (men)
• DEXA-derived body composition

What to do with this: if your dispensary doesn't order these, request them through your primary-care physician — or use a direct-access lab. Repeat the panel every 12 weeks during titration.

The protein number that keeps you from losing muscle

There is one daily input that single-handedly cuts muscle loss roughly in half. It's grams of protein per pound of bodyweight.

0.8 g/lb is the lean-mass-preservation threshold backed by GLP-1 muscle-loss studies. Hitting it is hard while the medication suppresses appetite — which is exactly why most patients miss it. Plan meals around protein first; everything else fills in around the edges.

The minimum effective training dose

Two days a week of resistance training is the floor. You don't need a gym. You don't need a coach. You need consistency.

Two 35-minute sessions per week cuts the lean-mass loss penalty by another ~18% on top of protein. Bodyweight versions work for absolute beginners. Lift before you eat on suppression days; the appetite often returns within an hour. The full guide includes a 2-day, 3-day, and 4-day program if you want to scale up.

The six supplements you can't skip

GLP-1s suppress appetite faster than they suppress nutrient need. These six cover what your reduced food intake stops delivering.

• High-quality multivitaminLook for B12 + folate. Daily.
• Magnesium glycinate300–400 mg/night. Cramps + sleep.
• Omega-3 (EPA/DHA)2–3 g/day. Inflammation + retention.
• Vitamin D3 + K25,000 IU + 100 mcg. Bone + immune.
• Creatine monohydrate5 g/day. Muscle preservation, period.
• Digestive enzymeWith each meal during titration.

What to look for: third-party-tested brands, no proprietary blends. NSF Certified for Sport, USP Verified, or Informed Choice are the three independent quality marks worth paying for.

Half your bodyweight in oz of water. With salt.

The brain fog isn't the drug. It's the dehydration. GLP-1s blunt thirst at the same rate they blunt hunger.

Constipation, fatigue, headaches, dizziness on stand-up — these are not "side effects" in the FDA-label sense. They are dehydration, and they resolve within 48 hours of hitting the water + electrolyte target. If they don't, talk to your physician.

The off-ramp that prevents regain

Most dispensaries put you on a GLP-1 and never plan an exit. That's the real reason patients regain — not the medication itself.

The average uninstructed patient regains fat-only mass within 1.7 years of stopping. The off-ramp is the difference between "I lost 50 lbs once" and "I'm 50 lbs down for good."
