Muscle Is the Exit Plan

Strength on a GLP-1: what the prescription starts, the body has to finish. No moralizing in either direction.

By Paula Lalanne · July 2026

First, the thing I say to every client before we talk strategy: the medication conversation belongs to you and your physician. I have no opinion about whether you should be on a GLP-1, and neither should your trainer, your group chat, or the internet. What I do have is a professional opinion about what to do with your body while you are on one, because that part is being left unmanaged in almost every case I see.

Here is the situation, without fear and without cheerleading. When weight comes off quickly and appetite drops sharply, the body does not neatly choose to lose only fat. Some of what goes is lean mass: muscle. Losing weight while quietly losing the muscle underneath is how women arrive at a smaller number feeling weaker, colder, and oddly less at home in their clothes. It is also how the exit goes badly: less muscle means a slower metabolic engine on the other side.

The prescription manages the appetite. Someone still has to manage the body.

The two-part job

The playbook for protecting muscle during rapid weight change is not exotic, and it has two parts that do not negotiate with each other.

Part one is resistance. Muscle stays when it is given a reason to stay, and the reason is load: strength training, two to four sessions a week, progressed sensibly for your history and joints. Walking is wonderful and does not count for this purpose. The work does not need to be loud or long. It needs to be consistent and progressively challenging.

Part two is protein, and this is where reduced appetite makes the math genuinely hard. When you barely want dinner, protein has to be deliberate: it goes first on the plate, it gets scheduled rather than left to hunger, and every small meal has to earn its place. This is precisely the kind of unglamorous logistics an advisor is for.

Planning the after

Appetite returns, in some form, for most people who come off the medication. The women who do well on the other side are the ones who spent the medicated months building the standard: the strength habit, the protein defaults, the sleep floor, the honest relationship with the mirror. The medication was a tool. The standard is the exit plan.

If nobody is managing this part of your prescription era, that is a solvable problem, and solving it is judgment-free work.
