First, check whether 150g is your number
One hundred and fifty grams is a popular round number, not a universal target. It happens to be roughly correct for a person around 75 to 90kg who trains.
The International Society of Sports Nutrition position stand on protein and exercise recommends 1.4 to 2.0 grams per kilogram of bodyweight per day for building and maintaining muscle in people who exercise. Run your own number:
| Bodyweight | 1.6 g/kg target |
|---|---|
| 55kg / 121lb | ~88g |
| 65kg / 143lb | ~104g |
| 75kg / 165lb | ~120g |
| 85kg / 187lb | ~136g |
| 95kg / 209lb | ~152g |
If you are noticeably above your ideal weight, calculating from goal weight or lean mass avoids inflating the target unnecessarily. Our full protein target breakdown covers that case.
The arithmetic that makes it manageable
One hundred and fifty grams sounds enormous until you divide it.
Three meals at 40g is 120g. One 30g snack closes it. That is the whole plan, and it is why the structure matters more than any individual food.
The reason people fail is almost never that 150g is unreachable. It is that they arrive at 6pm having eaten 45g and need 105g in one evening, which is genuinely hard and quietly miserable. Front-loading fixes this better than any other single change.
What 40g actually looks like
The number that matters is what 40g of protein is in real food, because most people badly underestimate portion sizes.
| Food | Amount for ~40g protein |
|---|---|
| Chicken breast | 140g cooked |
| Greek yoghurt (0%) | 400g |
| Eggs | 6 large |
| Cottage cheese | 320g |
| Lean beef mince | 150g cooked |
| Tinned tuna | 1.5 tins |
| Whey protein | 1.5 scoops |
| Firm tofu | 250g |
| Lentils, cooked | 450g |
That last row is why plant-based targets need more planning. It is achievable, and it needs a different structure. Our plant-based protein guide covers it.
A day that adds up to 150g
Not a meal plan to follow. A demonstration that the arithmetic works without eating chicken from a container six times a day.
Breakfast, 40g. Three eggs scrambled with 150g cottage cheese stirred through, on toast. Or 300g Greek yoghurt with berries and a spoon of protein powder.
Lunch, 40g. 140g chicken in a wrap or a rice bowl. Or two tins of tuna through a salad with beans.
Snack, 30g. A shake, 250g Greek yoghurt, or 150g cottage cheese with fruit.
Dinner, 40g. 150g of any meat or fish with whatever else you were having.
Total: 150g. No calculator, no misery, no six-container meal prep.
The three fixes that actually work
1. Front-load breakfast. The single highest-return change. Most people eat 10 to 15g at breakfast, usually cereal or toast, and spend the rest of the day behind. Moving breakfast to 35 to 40g removes almost the entire evening deficit. This is the one to do if you only do one.
2. Make protein the anchor, not the garnish. Decide the protein first and build the meal around it. Most people decide the meal, then discover the protein content afterwards. Reversing that order changes the outcome without changing what you eat much.
3. Keep two zero-effort 30g options in the house permanently. Greek yoghurt, cottage cheese, tinned fish, ready-cooked chicken, or a tub of whey. The day you are exhausted and behind is the day the target is lost, and it is lost to the absence of an easy option rather than to a decision.
Where the grams hide
Small consistent leaks that add up to 20 or 30g a day:
- Sauces and dressings displacing food volume. No protein, plenty of calories.
- Underestimating cooked versus raw weight. 150g raw chicken is about 110g cooked. Portion by cooked weight or you will overcount by a fifth.
- Assuming plant sources match animal sources gram for gram. They usually do not, per serving.
- Protein bars. Many contain 10 to 12g, not the 20g the packaging implies.
- Milky coffees counting as a snack. A latte is around 8g, which is fine, but it is not a protein snack.
Working up to it
If you are currently at 70g, do not jump to 150g tomorrow. It is uncomfortable, and the discomfort is what makes people quit in week one.
Add 15 to 20g a week. Week one, fix breakfast. Week two, add the afternoon snack. Week three, raise dinner. You will be at target inside a month, having changed three things rather than everything at once.
The bottom line
Three anchored meals of 35 to 40g plus one or two protein-forward snacks. Front-load breakfast, decide protein first, and keep two easy options permanently stocked.
The remaining problem is knowing where you actually are at 3pm, because you cannot correct a shortfall you have not noticed. That is the specific gap TrakMac fills: say what you ate and the running total updates in seconds, so the evening scramble becomes a small afternoon adjustment.
