GLP-1 Companion

Nobody sat you down and explained the gap.

These medications do one thing extremely well. They control how much you eat. They mimic a hormone your gut already makes, they keep the signal switched on, and the hunger stops being generated in the first place. That is why it feels less like dieting and more like food quietly stopped mattering.

But they have no opinion whatsoever about what you eat. None. You can lose 20 kg on toast and biscuits, and plenty of people do, because those are the foods that still go down when nothing appeals. The scale rewards you the entire way.

That is the gap. The drug handles how much. Nobody handed you a plan for the rest, and the rest is where your muscle, your metabolism and your results after you stop are all decided.

The number on the prescription that isn’t on the prescription

In the STEP 1 trial, participants lost an average of 15.3 kg on semaglutide. 6.92 kg of that was lean tissue. That is 45.2% of everything they lost. Not fat. Muscle, organ tissue, the structural parts. Across the wider evidence the figure ranges from about 15% to 60%.

Most people hear that and think about looking soft. That isn’t the problem. Muscle is where you store glucose. It is the largest site of insulin sensitivity you have. It is most of your resting metabolic rate. After about forty it is one of the better predictors of how the next thirty years go.

It is like losing weight off a house in a fire. Some of what goes was clutter and nobody misses it. Some of it was holding the roof up.

Now the part that makes this worth reading

None of it is inevitable. It is not the drug doing it to you.

In a twelve-month study of 106 patients on semaglutide, lean mass fell for seven months and then simply stopped falling. Grip strength went up by 4.5 kg over the year. The proportion meeting criteria for sarcopenic obesity dropped from 49% to 33%. They came out functionally stronger than they went in.

And in patients who deliberately trained resistance three to five days a week while on treatment, lean soft tissue was preserved.

The spread from 15% to 60% is not random. It is the difference between people who did something about it and people who didn’t.

This is the guide that tells you what the something is.

What’s inside

Twelve chapters. No padding.

1. What the drug does, and what it doesn’t. The three things that make everything else make sense.
2. What the scale isn’t telling you. The lean mass numbers in full, plus three tests you can do this week to find out where you actually stand.
3. The Protein Floor. Your single most important number, worked out from your goal weight rather than a generic target.
4. Protein first, every single time. The one behaviour that does most of the work, and why the order you eat in matters more than it ever has.
5. The Calorie Floor. The minimum, the signals that tell you you’re under it, and what goes wrong when you are.
6. Two sessions a week, non-negotiable. Twenty-five minutes, six movements, written for someone with low energy and no gym confidence. Plus dumbbell-only and bands-only versions.
7. The gut chapter. Nausea, reflux, constipation, sulphur burps, and the seventy-two hours after every dose step.
8. The things that show up at month three. Hair shedding, facial volume, bone, gallbladder risk, and which ones warrant a phone call rather than a worry.
9. Supplements. Split honestly into what is safe to take without being screened and what genuinely is not, with the specific reason for each.
10. Eating in the real world. Restaurants, travel, family meals, the guilt about waste, and being watched not eat.
11. A worked fortnight. Fourteen days of real meals that clear both your floors every single day, with the numbers shown.
12. The Off-Ramp. What happens when you stop, why roughly two-thirds of the weight typically comes back within a year, and the twelve-week plan that changes that.

And the toolkit

Every number the calculator produces is also printed as a lookup table, so the protocol works in full on paper.

Who wrote this

I’m Eloy Rodriguez. I run Carbon IV, a performance nutrition and strength coaching practice in Dubai.

I wrote this because the same conversation kept happening. Someone starts one of these medications, the weight comes off, and six months later they’re sitting in front of me tired, weaker, losing hair, and completely blindsided, because everything went to plan and nobody told them what the plan was missing.

The medication was never the problem. The silence around it was.

This is the guide I wanted to hand those people at the start.

Questions

Is this instead of my medication?

No, and nothing in it suggests stopping or changing anything. Your dose, your titration and your decision to start or stop belong entirely to you and your prescriber. This guide covers food and training, which is the part nobody else is covering.

What format is it?

Two PDFs and a web-based calculator. Download the PDFs to any device. The calculator opens in a browser on any phone or laptop, with nothing to install and no account to create.

I haven’t started the medication yet. Is it too early?

It’s the best time. Chapters 1 to 6 are preparation, and people who set the protein and training habits before they start find the whole thing considerably easier.

I’ve already stopped. Is it too late?

No. Chapter 12 is written for exactly that window, and the twelve weeks after you stop are the period where the most is still winnable.

I’m not a gym person.

Chapter 6 assumes that. Twenty-five minutes, twice a week, six movements, four of them on machines that are hard to do badly. There are dumbbell-only and bands-only versions too.

Will this work if I have other conditions?

The guide is general education, not individual advice. Chapter 9 is deliberately explicit about which supplements need screening before you take them, and points you to a conversation rather than a purchase. If you want it applied to your own situation, that’s what a consultation is for.

You’re already doing the hard part.

The medication has opened a window that most people never get. What happens inside that window, and what’s left when it closes, comes down to two things: enough protein, and two sessions a week.

This is the guide that makes both of them straightforward.

For general education. Does not replace individual medical advice. Nothing in this guide is advice about your medication. Your dose, your titration and your decision to start or stop belong to you and your prescriber. If you are unwell, or any symptom is severe or persistent, contact your prescriber.
