Dr. Gabrielle Lyon wants protein treated as medicine. Here's how to turn that into a client's protein target - and actually track it.
Most clients under-eat protein, and most coaches set it last - whatever's left after calories and carbs are decided. Lyon's "muscle-centric medicine" flips that: protein first, because muscle is the organ she's really coaching for health and longevity. This breakdown covers her argument in our own words, adds our honest take for a client roster, and shows how to set a per-meal protein target once and watch adherence for real.
By Markus Evers · September 2026 · a Coachway video breakdown
the short version
Lyon's message is that skeletal muscle is the organ of longevity, so protein should be prioritised - she advocates a target around one gram per pound of ideal bodyweight, distributed across meals with a protein-rich first meal, paired with resistance training. The one thing a coach should do about it: stop leaving protein as the leftover macro. Set an explicit daily protein target per client, front-load the first meal, and track whether it's actually hit instead of assuming.

Who is Dr. Gabrielle Lyon, and why coaches watch
Dr. Gabrielle Lyon is a physician who coined and champions "muscle-centric medicine" - the idea that skeletal muscle, not fat, is the organ we should build health and longevity around. She's become a fixture on the biggest health and longevity podcasts, and her signature message is that most people, especially as they age, chronically under-eat protein. For coaches she matters because she brings a clinical, longevity framing to a topic your clients already care about - and her audience skews toward the older, health-motivated clients that many coaches want more of. This page isn't "should I copy Lyon's protein number," but "what does her protein-and-muscle-first argument mean for how I set and track nutrition across a roster."
What Lyon actually argues (our summary)
This is our summary of her documented, muscle-centric positions, in our own words - not a transcript. Watch the original for her exact examples and clinical framing.
- 1
Muscle is the organ of longevity. Her core reframe is that skeletal muscle isn't just for aesthetics or strength - it's a metabolic organ central to healthy ageing, so protecting and building it becomes a health priority, not a bodybuilding one.
- 2
Most people under-eat protein. She argues the common protein advice is set too low, and publicly advocates a target in the region of one gram per pound of ideal bodyweight - meaningfully higher than the minimum many clients are told is enough.
- 3
The first meal matters most. She emphasises front-loading protein: a genuinely protein-rich first meal to switch on muscle protein synthesis, rather than a carb-heavy breakfast with most of the day's protein crammed into dinner.
- 4
Distribute protein across meals. The target isn't one big hit - it's spread across roughly three protein-anchored meals, with the rest of the plate built around the protein rather than the other way round.
- 5
Protein and resistance training go together. Adequate protein does its job alongside consistent lifting - she pairs the nutrition message with resistance training as the two levers that protect muscle for the long term.
Coachway's take
We're fully on board with the central move: protein first. In practice most coaches set calories, then carbs and fats, and protein lands wherever the remainder allows - which is exactly how clients end up chronically short. Flipping the order so protein is the anchor, and building the rest of the plate around it, is the single most reliable nutrition upgrade for the average client. Lyon's longevity framing is also genuinely useful for selling the habit to older clients who don't care about a "pump" but do care about staying strong and independent.
Where we'd add nuance for a coaching business: the "one gram per pound of ideal bodyweight" target is a strong, defensible starting point, not a law. For a client who's currently eating half that, the win is closing the gap - getting them from, say, an obviously-too-low intake up toward the target - long before you argue about the last few grams. Adherence to a slightly lower number beats a perfect number they never hit. Treat the figure as a direction to move in, individualised to the client's size, goal and how much change they can actually sustain.
The other coaching-specific point: protein is the macro clients most consistently over-report. "I get plenty of protein" almost never survives a few days of honest logging. So the muscle-first message only pays off if you can see the truth - which meal is short, whether breakfast is still a bagel, whether the target is real or aspirational. And the medical caveat matters more with Lyon's older-client audience: whole-food sources first, sensible targets, and defer to a client's physician on genuine medical questions rather than overriding them.
So our version of her advice is: set an explicit daily protein target, front-load the first meal, pair it with two to three resistance sessions a week, and then make all of it trackable so you're coaching from real adherence data. Set the per-meal target once as a template and reuse it across similar clients, instead of re-deriving protein from scratch every time.
Set the protein target once, then watch it get hit
A protein target is only useful if the client hits it and you can see when they don't. That's where Coachway's meal planner comes in: set the daily protein target and a per-meal split, build a protein-anchored first meal from a large ingredient and recipe database, and deliver it inside the client's app where they log their food against it every day. Because protein is the macro clients most over-report, the point is that you see intake against target at each check-in - not a claim, the actual number - and can tell exactly which meal is falling short. Pair it with a couple of resistance sessions built in the workout builder, and Lyon's two levers - protein and lifting - are both programmed and both tracked in one place.
If you want the how-to first, our guide to setting protein targets for clients walks through the numbers, and protein timing covers the per-meal distribution side of the same equation - the "how you spread it" that Lyon's first-meal emphasis is really about.
Muscle-first nutrition handout (client-ready)
A handout you can copy for any client who needs their protein anchored. It sets a daily target, front-loads the first meal, spreads the rest across the day, and pairs it with resistance training - the muscle-first structure - then makes it a simple daily log. The per-meal split below is a practical default for a 3-meal day; adjust the grams to the client's size, goal and appetite.
Muscle-first nutrition plan
The daily target
- •Daily protein target: ~1 g per lb of goal bodyweight (a defensible starting point - individualise it).
- •First meal is the priority: 30-50 g quality protein to start the day, not a carb-only breakfast.
- •Anchor every meal in protein: aim for ~3 protein-anchored meals; build the rest of the plate around them.
- •Train the muscle you're feeding: 2-3 resistance-training sessions per week.
Per-meal protein split (3-meal day)
| Meal | Protein focus | Example protein sources | Hit? (Y/N) |
|---|---|---|---|
| First meal | Front-loaded, 30-50 g | Eggs, Greek yogurt, cottage cheese, whey | — |
| Midday meal | Anchor the plate | Chicken, fish, lean beef, tofu, legumes | — |
| Evening meal | Anchor the plate | Fish, poultry, lean meat, tofu, eggs | — |
| Optional snack | Top up if short | Yogurt, jerky, protein shake, edamame | — |
How to use it: set the daily target first, front-load the first meal, and let the other meals carry the remainder. Whole-food sources first; a shake fills a genuine gap. Protein needs and any medical considerations are individual - keep targets sensible and defer to a client's physician on genuine medical questions.

Protein for clients - FAQ
How much protein should clients eat, according to Dr. Gabrielle Lyon?
Lyon's public position is that most people under-eat protein, and she advocates a target in the region of one gram per pound of ideal bodyweight - notably higher than the minimum many people are told. Her framing is that this is about protecting skeletal muscle as an organ of health and longevity, not just building it. For a coach, the practical read is to treat protein as the anchor of the plan and set an explicit daily target per client rather than letting it land wherever the rest of the diet leaves room.
Why does Dr. Lyon emphasise the first meal of the day?
Her muscle-centric approach puts weight on front-loading protein: making the first meal genuinely protein-rich rather than carb-dominant, so the day starts with a real dose of protein instead of most of it being crammed into dinner. She frames adequate per-meal protein as the trigger for muscle protein synthesis. The coaching takeaway is to distribute protein across the day - roughly three protein-anchored meals - and to pay special attention to breakfast, which is where most clients fall short.
Is a high-protein diet safe for older clients?
Lyon's whole argument is aimed largely at ageing populations: she treats muscle loss with age as a bigger risk than most clients appreciate, and positions adequate protein plus resistance training as protective. That said, protein needs and any medical considerations are individual, so a responsible coach keeps protein targets sensible, encourages whole-food sources first, and defers to a client's physician on genuine medical questions like kidney concerns rather than overriding them.
How should a coach turn Lyon’s protein message into a client plan?
Set a daily protein target (Lyon's roughly one gram per pound of ideal bodyweight is a defensible starting point), split it across about three meals with a protein-rich first meal, and pair it with a couple of resistance-training sessions a week - because in her model protein and training work together, not separately. Then make it trackable: have the client log whether they hit protein and completed their lifts, so you are coaching from real adherence data instead of assuming the target is being met.

all guidesHow to Set Protein Targets for Clients (2026 Method)
Setting a client's protein target is a per-kilogram decision, not a generic macro split: pick a range from goal and training age (1.6 to 2.2 g/kg to build, 1.8 to 2.4 in a deficit), base it on lean or goal weight for heavier clients, split it across three to five meals, and coach it to the number they will actually hit.
