A GLP-1 on a budget: protein per dollar, no equipment, no supplements

After the pharmacy bill there is not much left for organic chicken and a gym membership. The cheapest protein in the shop is also the easiest to eat on a small appetite, and the training that keeps muscle needs a chair and a doorway.

The short answer

Keeping muscle on a GLP-1 costs almost nothing beyond the medication. The cheapest protein in any supermarket, eggs, milk, tinned fish, chicken thigh, mince, lentils and a big tub of yoghurt, is also the easiest to eat on a small appetite. The training that holds a strength test steady needs a chair, a doorway and a backpack. And no supplement is required: not creatine, not collagen, not electrolyte powders. Two sessions a week, protein at 1.2 to 1.6 g per kilogram of goal weight (0.55 to 0.7 g per pound), and three numbers on a Sunday.

Rank protein by cost in your currency

The protein budget, in grams

Start with the number, not the shopping. A 70 kg (154 lb) goal weight needs 84 to 112 g of protein a day, which is around 700 g a week at the middle of the range. Set your own number in the protein calculator. Then the question becomes what 10 g of protein costs from each food in your shop, and the answer is more lopsided than most people expect: the cheapest sources deliver 10 g for a fraction of what a protein bar or a ready-made shake charges for the same grams.

Our protein per dollar tool ranks thirty foods by the cost of 10 g of protein in Australian dollars, US dollars and pounds, and lets you type in your own local prices so the table reorders for your supermarket. Run it once and the shopping list writes itself.

The cheap list, and why it suits a small appetite

  • Milk and milk powder A glass of milk is about 8 g; a shake made on milk with a scoop of powder is about 33 g for the price of a coffee. Skim milk powder stirred into anything adds protein for almost nothing. Soy milk if you are plant-based; almond milk carries almost no protein at any price.
  • Eggs About 6 to 7 g each, boil a dozen on Sunday and the afternoon stop is done for the week.
  • Tinned fish Tinned tuna and sardines deliver 20 g or more a tin, keep for years, and need no fridge, no cooking and no appetite.
  • Chicken thigh and mince Chicken thigh is usually far cheaper than breast per gram of protein and easier to eat when the mouth is dry. Beef mince and turkey mince cook in bulk and freeze in portions.
  • Frozen fish Plain frozen fillets cost a fraction of fresh and bake from frozen in twenty minutes.
  • Lentils, beans and tofu The cheapest protein in the shop, with the caveat that beans carry their protein in a lot of food. Firm tofu and red lentils are the concentrated options for a small stomach.
  • The big tub of Greek yoghurt and cottage cheese The 1 kg (35 oz) tub costs far less per serve than the single pots, and 200 g (7 oz) is about 20 g of protein.
  • Protein powder, bought in bulk Not a supplement, a food. A large bag of plain whey or a pea and rice blend works out cheaper per 10 g than nearly every bar and every ready-made shake, and it is the easiest 30 g of the day when eating is hard.

What to skip: protein bars, ready-made shakes, anything labelled high-protein at a premium, collagen, and the little pots. They are convenient and they are the most expensive protein in the building. The full foods index ranks the meat and fish options by protein per serve, and the per-medication guides to protein on a budget walk through a week.

A cheap day at about 100 g, in grams and ounces

  • Breakfast Two boiled eggs and a glass of milk, 250 ml (8.5 fl oz), about 21 g.
  • Mid-morning A scoop of bulk whey in 250 ml (8.5 fl oz) of milk, about 33 g.
  • Lunch A 95 g (3.4 oz) tin of tuna with a slice of toast and a tomato, about 20 g.
  • Dinner 120 g (4 oz) of chicken thigh or mince with a potato and frozen vegetables, about 30 g.

Around 104 g of protein, nothing fresh that spoils, and every item bought in bulk. Build your own plate in the meal protein builder, which totals the protein as you add foods and warns you when the plate is too large for a GLP-1 appetite.

Training with no equipment at all

The requirement is two 30-minute sessions a week across six movements with enough load that the last two repetitions are hard. Nothing in that sentence needs a membership.

  • Squat pattern Sit-to-stand from a dining chair, then a lower chair, then holding a backpack full of books.
  • Hinge A hip hinge to a chair seat, then a glute bridge on the floor, then a single-leg bridge.
  • Push A push-up against the kitchen bench, then a lower surface, then the floor on the knees.
  • Pull A towel looped around a door handle, lean back and row. Then a heavier backpack held to the chest and rowed from a hinge.
  • Carry Two shopping bags or two 3 litre (100 fl oz) water bottles, the length of the hallway and back, three times.
  • Core brace A plank on the knees, then the toes, then a dead bug.

Progress by making the position harder or the backpack heavier, and write it down. When you are ready to spend anything, a long resistance band and a pair of adjustable dumbbells cover the next two years, and training at home on a budget sets out what to buy in what order. A gym is a fine choice and never a necessary one.

Why no supplement is needed

The two things that decide whether you keep muscle are protein at the target and load twice a week. Creatine, collagen, amino acid drinks, electrolyte powders and the rest sit a long way behind those two, and none of them substitutes for either. If the budget has to choose between a tub of creatine and a bag of whey, the whey wins every time, because it is the protein you were short of. Electrolytes come from salt on your food and 2 litres (68 fl oz) of fluid a day; a rehydration sachet after loose stools is the only time a product earns its place.

The exception is medical, not nutritional. If a blood test shows low iron, B12 or vitamin D, your prescriber may want you to take something, and that is their call. Ask before adding any supplement, particularly with kidney problems or other medication.

The waste problem, and batch cooking

On a small appetite the expensive part of food is the part you throw away. A tray of chicken thighs roasted on Sunday and portioned into 120 g (4 oz) bags, a pot of lentils, a dozen eggs, a bag of frozen fish and a tub of yoghurt cover the week and nothing goes off. Cook on the days you can eat, which on a weekly injection are usually days four to seven, and the quiet days run on what is already in the fridge.

What is free, and what is not

Everything you need to run the plan is free on this site: the calculator for the number, protein per dollar for the shopping, the meal builder for the plate, the strength test tracker for the weekly number, and the guides for the weeks that go wrong. The one thing we sell that fits a tight budget is the Keep Muscle Kit at A$47 / US$29 / £23, which puts the whole system in five PDFs, and nobody needs it to start. Start with the number and the eggs.

Then take the three numbers every Sunday: one strength test, your seven-day protein average, and a tape around the upper arm. They cost nothing, and they are the only way to know that the cheap plan is working, which in the people we coach it does.

Free, one page

Forty foods, ranked by protein per bite

The hard part is not knowing you need protein, it is hitting the number on a day when food is the last thing you want. One page, grams and ounces, what a real serve looks like, and the first-bite rule for when appetite is gone. Print it and put it on the fridge.

Then five short emails over five days on keeping muscle while the weight comes off, and a short note every fortnight after that if you want it. One click to stop, any time.

Questions people ask

What is the cheapest way to hit my protein target on a GLP-1?

Eggs, milk, tinned fish, chicken thigh, mince, lentils, a large tub of Greek yoghurt and plain protein powder bought in bulk. Our protein per dollar tool ranks thirty foods by the cost of 10 g of protein in your currency, with your own prices.

Do I need a gym to keep muscle on a GLP-1?

No. Two 30-minute sessions a week across six movements, with enough load that the last two repetitions are hard, can be done with a chair, a doorway, a towel and a backpack. A band and two dumbbells are the first things worth buying, and a gym is optional.

Do I need creatine, collagen or electrolytes on a GLP-1?

No. Protein at the target and two loaded sessions a week decide whether you keep muscle; supplements sit a long way behind. Salt on your food and 2 litres (68 fl oz) of fluid cover electrolytes. Ask your prescriber before adding anything, particularly with kidney problems.

Is protein powder worth the money?

Bought in bulk as plain whey or a pea and rice blend, yes: it is usually cheaper per 10 g of protein than bars or ready-made shakes, and it is the easiest 30 g of the day when eating is hard. Treat it as a food, not a supplement.

Are protein bars a good option on a budget?

They are the most expensive protein in the shop and many carry sugar alcohols that upset a GLP-1 gut. A tin of tuna, two boiled eggs or a tub of yoghurt delivers the same grams for far less.

What the cheap version has to deliver

Money buys convenience here, not results. Eggs, milk and a band reach both of these figures as well as anything expensive does.

Each of those meals wants roughly 2.5 to 3 g of leucine, the amino acid that actually switches muscle building on. That is about 30 g of whey, 120 g of chicken breast, or four eggs. Arslan S, Clinical Nutrition ESPEN 2026

Supervised resistance training for longer than 10 weeks has produced gains of around 3 kg (6.6 lb) of lean mass and around 25% in strength in adults. Locatelli JC et al, Diabetes Care 2024
