The Rep Guide

Protein & Nutrition

Eight guides with one job: get enough protein every day from food you will actually eat. Start with your number, see what it looks like on a plate, then build it into meals. Every portion is in grams and every total is added up for you.

Food is half of what makes lifting work. The other half is the training: if you have not started yet, begin with the Start Lifting section and come back here once you are in the gym two or three times a week. If you are already training, find the row that sounds like you.

Five numbers every guide here uses

  • 1.6 g of protein per kilogram of bodyweight a day, which is 0.7 g per pound. That is where extra protein stopped adding measurable muscle in a 2018 meta-analysis of 49 lifting studies by Morton and colleagues. Lifters in a calorie deficit go higher, to 1.8 to 2.2 g/kg.
  • 25 to 40 g per meal, over three or four meals. About 0.4 g/kg each time. The daily total matters most; spreading it out is just the easiest way to reach it.
  • 4 calories per gram of protein. So 100 g of protein is 400 calories at the very least, and pure protein tops out at 25 g per 100 calories. Every food is measured against that ceiling.
  • The 25 g block. A can of tuna, a cup of Greek yogurt, 85 g (3 oz) of cooked chicken breast or four eggs. Four blocks is 100 g. Learn the blocks once and you rarely need a food log.
  • Daily total first, timing a distant second. A protein meal within a few hours either side of training is enough. There is no 30-minute window to race.

What the targets look like at three common weights:

BodyweightDaily target, 1.6 g/kgPer meal, 4 mealsIn 25 g blocks
60 kg (132 lb)~95 g~24 g4
75 kg (165 lb)~120 g~30 g5
90 kg (198 lb)~145 g~36 g6

The full chart, from 110 to 240 lb, and the numbers for cutting, for lifters over 50 and for plant-based eaters are on the protein target page.

How the guides connect

The order follows the questions people ask in the order they ask them. First the target: how many grams. Then the picture: what 100 g of protein looks like on a plate, food by food, and why 100 g (3½ oz) of chicken is only about 31 g of protein. Then the days: the meal plan writes out three of them with a shopping list and a one-hour Sunday prep.

The next four pages fix the meals that usually fall short. Breakfast is the most common gap, often 10 to 15 g when it should be 30. The afternoon is the second, which is what the snack ranking and its label test for candy-style protein bars are for. On a cut, the job changes to fitting the same protein into fewer calories, so the low-calorie list ranks foods by grams per 100 calories instead of grams per serving. And because eating the same four foods is how most people quit, the cottage cheese page turns one cheap tub into ten different meals.

The last guide, eating around training, comes last on purpose. Once the daily total is right, the meal before a session only needs to be the right size at the right time.

What this section does not cover

There are no calorie targets for weight loss here and no crash diets. Protein does not make you lose weight; total calories decide that, and the guides that touch cutting keep the deficit modest. Putting food and training together to build muscle lives in the Build Muscle section, which also has the creatine guide, the one supplement with strong evidence behind it. Protein powder appears on these pages as a convenience, never as a requirement: every plan and every table works with ordinary food.

If you have kidney disease, diabetes with kidney involvement, are pregnant or breastfeeding, or have been told to limit protein, set your numbers with your doctor rather than from a chart. Food values on every page are rounded from USDA FoodData Central and typical US labels, and how we make these guides explains how each one is checked.
