Your protein chart
On a GLP‑1 medication, somewhere between a quarter and forty percent of the weight you lose can be lean tissue rather than fat. Protein is the single strongest thing you control. Find your weight, then read across.
Daily and per‑meal targets
| Body weight | Protein per day | Per meal (3 meals) |
|---|---|---|
| 120 lb / 55 kg | 65 – 88 g | 22 – 29 g |
| 140 lb / 64 kg | 76 – 102 g | 25 – 34 g |
| 160 lb / 73 kg | 87 – 116 g | 29 – 39 g |
| 180 lb / 82 kg | 98 – 131 g | 33 – 44 g |
| 200 lb / 91 kg | 109 – 145 g | 36 – 48 g |
| 220 lb / 100 kg | 120 – 160 g | 40 – 53 g |
| 250 lb / 113 kg | 135 – 160 g* | 45 – 53 g |
| 280 lb / 127 kg | 140 – 165 g* | 47 – 55 g |
Above roughly 220 lb, most clinicians calculate protein on an adjusted body weight rather than actual weight, which is why the last two rows level off instead of continuing to climb. Ask your prescriber or a registered dietitian to set your number precisely.
The rule that matters more than the daily total
Your muscle does not read a daily total. It reads each meal separately. A meal has to cross a threshold before your body registers it as a reason to keep muscle — roughly 2.5 grams of leucine under age 65, and closer to 3 grams over 65. In practical terms that is 25–30 g of quality protein per meal if you are under 65, and 30–40 g if you are over.
This is why 30 / 30 / 30 beats 15 / 15 / 70. Same daily total. Very different outcome.
Four habits that do the work
- Protein first, every meal. Before the carbohydrate, before the vegetables. If the medication means you only finish half a plate, that half should be protein.
- Front‑load breakfast. GLP‑1 fullness builds through the day. Morning is when your capacity is highest, so take the largest protein serving then — not at dinner.
- Work around the injection. Nausea generally peaks in the first one to three days after a dose. Load your protein onto the days furthest from the injection, and use a shake on the days solid food is impossible. That is what shakes are for. It is not cheating.
- Watch the floor. Appetite suppression makes an 800‑calorie day feel unremarkable. Sustained below roughly 1,200 calories for women or 1,500 for men, muscle loss accelerates no matter how much protein you eat. Count your intake once a week just to check.
On supplements
- Whey protein isolate is the most useful single purchase. It runs about 10–12% leucine by weight, so a 30 g serving clears the threshold at any age.
- Free leucine powder is widely sold and largely unnecessary. Leucine is the ignition switch, not the building material — take it alone and you start an assembly line with no parts on it. Get your leucine inside a complete protein.
- HMB (3 g/day) is a leucine by‑product with reasonable evidence for reducing muscle breakdown during a calorie deficit, particularly in older adults.
- Creatine monohydrate (3–5 g/day) helps — but only alongside resistance training. Without exercise it does very little.
- Vitamin D is worth testing rather than guessing. Correct a documented deficiency; don't supplement blind.
Higher protein intake is not appropriate for everyone. If you have kidney disease, liver disease, or are being treated for any condition affecting protein metabolism, these targets do not apply to you and must be set by your physician. Nothing here replaces the advice of the clinician who prescribed your medication.
Foods that make you chew
The masseter is the most use‑dependent muscle in your face. It thins when you lose teeth, when premolars are extracted for braces, and when your diet gets softer. GLP‑1 medications quietly remove its job — smaller bites, fewer chews, and a drift toward shakes and soup. This list is organised by how hard the food makes you work, not just by protein content.
High chew demand — build meals from this group
| Food | Serving | Protein |
|---|---|---|
| Steak, sirloin or flank | 4 oz | 33 g |
| Chicken breast, roasted | 4 oz | 35 g |
| Turkey breast, roasted | 4 oz | 34 g |
| Pork loin chop | 4 oz | 32 g |
| Beef or turkey jerky | 2 oz | 22 g |
| Tempeh | 4 oz | 22 g |
| Aged hard cheese | 2 oz | 14 g |
| Almonds | 1 oz | 6 g |
Moderate chew demand — good, and easier on low‑appetite days
| Food | Serving | Protein |
|---|---|---|
| Salmon or tuna steak | 4 oz | 29 g |
| Shrimp | 4 oz | 24 g |
| Canned tuna | 5 oz | 33 g |
| Eggs, hard‑boiled | 3 large | 19 g |
| Edamame, shelled | 1 cup | 18 g |
| Lentils, cooked | 1 cup | 18 g |
| Chickpeas, roasted | 1 cup | 15 g |
| Firm tofu, seared | 4 oz | 12 g |
Low chew demand — useful protein, no muscular work
Greek yogurt, cottage cheese, protein shakes, soups, smoothies, and scrambled eggs all deliver protein perfectly well. They simply do not ask anything of your jaw. Use them on the days the medication makes solid food impossible — and treat that as the fallback, not the default.
Chew your protein instead of drinking it, every day you can tolerate it. Every shake substituted for a solid meal is a meal your masseter and temporalis did not work for.
Two practical additions
- Cut food larger, not smaller. Bigger pieces mean more chewing cycles per bite. Small dice does the muscle's work for it.
- Sugar‑free xylitol gum after meals is worth considering — but read Resource 4 before you start. There is a reason a jaw surgeon puts a condition on that advice.
If you cannot chew
If a jaw joint disorder means chewing is painful, or your jaw locks or tires within minutes, the main tool in Resource 2 is one you cannot use. You are still losing muscle on a GLP‑1 like everybody else. Here is what the research supports instead, in order of how strong the evidence actually is.
Your jaw is limited. Your body is not. Full‑body resistance training remains completely available to you, and it is the single strongest intervention discussed anywhere in these resources — stronger than any supplement on this page. Twice a week, adding load progressively.
Protein: for you, a shake is the ideal delivery
For most people a protein shake is a fallback. For you it is the best possible vehicle. Whey isolate is roughly 10 to 12% leucine by weight, so a 30 g serving crosses the threshold that switches on muscle building while asking nothing of your joint. Three servings spread across the day solves the protein problem outright.
High‑protein foods that need almost no chewing:
| Food | Serving | Protein |
|---|---|---|
| Whey isolate powder | 1 scoop | 25 – 30 g |
| Greek yogurt, plain | 1 cup | 20 g |
| Cottage cheese | 1 cup | 24 g |
| Eggs, soft scrambled | 3 large | 19 g |
| Flaked salmon or tinned tuna | 4 oz | 29 g |
| Blended lentil or bean soup | 1.5 cups | 18 g |
| Silken tofu, blended | 6 oz | 14 g |
| Ricotta | 1 cup | 28 g |
Supplements, ranked by evidence
| Supplement | Dose | What the evidence supports |
|---|---|---|
| Creatine monohydrate | 3 – 5 g daily | The most studied supplement in sports nutrition and among the cheapest. Works alongside training; without exercise the effect is small to absent. |
| HMB | 3 g daily | A leucine by‑product. Slows muscle breakdown rather than building muscle — which is what a calorie deficit calls for. Strongest evidence in older and deconditioned adults. |
| Vitamin D | Test first | Correct a documented deficiency. Do not supplement blind. |
| Omega‑3 (EPA + DHA) | 2 g or more daily | Mixed evidence. Behaves as an amplifier of the muscle response to protein rather than acting alone. Most likely to help older adults. |
What I would not spend money on
- Standalone leucine powder. Leucine is the ignition switch, not the building material. Without the other essential amino acids you start an assembly line with no parts on it.
- Branched‑chain amino acids on their own. Same problem, and whey delivers them anyway.
- Collagen taken for muscle. It is a poor‑quality protein for this purpose, low in leucine.
- Anything marketed for jawline definition. No supplement has been shown to preserve any individual facial muscle. Everything on this page acts systemically.
Complete disuse is worse than limited use. Chew what you can — gently, evenly on both sides, staying inside the range that does not produce pain. And understand that “I cannot chew” is a diagnosis waiting to be made, not a permanent condition. Most people who say it have never had the joint imaged. If the disc is displaced, that is a finding with a name and a stage, and there is often something that can be done about it. Resource 3 below is how to start that conversation.

What to ask your dentist
Social media is full of advice to chew hard gum for a stronger jawline. For a healthy joint that is reasonable. For a joint with a displaced disc — and a great many people have one and have never been told — it is not muscle training. It is loading a torn ligament. Before you add any chewing work, run the five‑minute test.
The five‑minute test
Chew a piece of gum, normally, for five minutes. Then stop and ask three questions.
- Noise. Did you hear or feel clicking, popping, grating, or crunching in front of either ear?
- Pain. Any ache in the joint, the temple, or along the jaw — during or in the hour afterward?
- Fatigue. Did the jaw tire in a way that felt different from ordinary muscle work?
Any one of these is not a training signal. It is a joint signal. Stop the chewing programme and get the joint properly examined before you do anything else with your jaw.
Train the muscle only over a stable joint.
What to say at the appointment
Opening the conversation
“I've had some jaw noise and discomfort with chewing. I'd like a proper temporomandibular joint examination, not just a check for grinding. Can we do that today?”
Asking about imaging
“If the examination suggests the disc may be out of position, is MRI indicated? I understand a panoramic X‑ray and a CBCT show bone but not the disc or the ligaments.”
Asking for a staged diagnosis
“If I do have joint changes, can you tell me what stage they are — and can that be written into my record so it can be tracked over time?”
What a complete examination should include
- Measurement of how far you can open, and whether the jaw deviates to one side as it opens
- Listening and feeling at both joints through a full opening and closing cycle
- Loading and manipulation of each joint to reproduce your symptoms
- Palpation of the masseter, temporalis, and the muscles of the neck
- An assessment of whether your bite has changed — and when
- A record of both joints separately. The two sides are frequently at different stages.
Why MRI, and what it shows
The articular disc and the ligaments that hold it in place are soft tissue. They do not appear on a panoramic X‑ray or on a cone‑beam CT, both of which show bone. If the question is whether the disc has moved and whether the ligaments are stretched or torn, MRI is the study that answers it. Images are generally taken with the mouth both closed and open, and both joints are examined.
Imaging is not needed by everyone. It becomes worth discussing when there is joint noise with pain, a bite that has changed, limited opening, or symptoms that are not improving.
Which sequences a TMJ study should include is not obvious, and many imaging centers have never been asked for one. The protocol I developed and taught to dentists over forty years is published free, in three tiers — the screening study is only four sequences. Print it and hand it to your dentist or your imaging center.
Grinding and clenching are real and common, and a night guard helps many people. But “wear a night guard and manage your stress” offered without an examination of the joints is not a diagnosis. It is reasonable to ask for the examination first and to seek a second opinion if it isn't offered.
