Eating for lifting

Start here

For: adults who lift and want to understand the nutrition ranges in the reviews cited below.

Practical order: understand your goal, use the protein and calorie ranges as starting estimates, then compare your average bodyweight and training over time. The worked day is an illustration, not a personal meal plan.

First action: read the worked example alongside its assumptions. Physique can record bodyweight and lifting progress; it does not prescribe a diet.

Every program on this site asks the body to recover from more than it did last week. Food is one part of recovery alongside rest and training load. This page gives the numbers that the sports-nutrition position stands and reviews give, with the source next to each one, and turns them into a day of eating for one lifter. It does not prescribe anything for you in particular, and it stops where the sources stop.

Protein

The International Society of Sports Nutrition’s position stand: “an overall daily protein intake in the range of 1.4–2.0 g protein/kg body weight/day (g/kg/d) is sufficient for most exercising individuals.” Morton and colleagues’ 2018 meta-analysis of 49 trials found that protein beyond about 1.6 g/kg/day “provided no further benefit on gains in muscle mass or strength,” and, because the confidence interval reached 2.2, that “it may be prudent to recommend ~2.2 g protein/kg/d for those seeking to maximise resistance training-induced gains.” Iraki’s 2019 review for lifters in a gaining phase lands on the same range: 1.6 to 2.2 g/kg/day, spread over three to six meals of about 0.40 to 0.55 g/kg each.

So: 1.6 to 2.2 g per kilogram of bodyweight a day is a practical range discussed in the cited research, not a guaranteed threshold for an individual. An 80 kg lifter is at 128 to 176 g a day. In pounds, that is roughly 0.7 to 1 g per pound.

For lean, resistance-trained athletes in a calorie deficit, Helms and colleagues discuss 2.3–3.1 g/kg of lean body mass, scaled to leanness and the size of the deficit. That denominator matters: this is not the same as multiplying total bodyweight by the range. It is a context-specific recommendation, not a universal target for everyone losing weight.

Calories

Gaining

The ISSN’s diets-and-body-composition stand says what everyone suspects: “Diets focused primarily on accruing LM are driven by a sustained caloric surplus.” How big is the question. Iraki’s recommendation: “a slightly hyper-energetic diet (~10–20% above maintenance calories) with the aim of gaining ~0.25–0.5% of bodyweight per week,” with advanced lifters “more conservative with the caloric surplus and weekly weight gain,” at the low end or below it.

For an 80 kg lifter that is 200 to 400 g a week, 0.8 to 1.6 kg a month. For a 180 lb lifter, roughly half a pound to a pound a week. These are example rates from the review, not guarantees about how much muscle an individual will gain.

Losing

The same stand: “Diets primarily focused on fat loss are driven by a sustained caloric deficit,” and “The higher the baseline body fat level, the more aggressively the caloric deficit may be imposed.” As you get leaner, slower is better for keeping muscle: the stand cites a trial where losing 0.7% of bodyweight a week kept lean mass better than 1.4%. Helms’ review for natural bodybuilders concludes that “weight loss of approximately 0.5 to 1% of bodyweight weekly may be superior for LBM retention compared to shorter or more aggressive diets.”

So 0.5 to 1% of bodyweight a week, the lower figure when you are already lean, with protein at the cutting level above.

Fat and carbohydrate

Iraki’s off-season review, after protein is set: fat at 0.5 to 1.5 g/kg/day, and the rest of the calories from carbohydrate, “≥3–5 g/kg/day” where possible, because that is what fuels the volume work. The ISSN stand’s position on diet type, in its own words: “A wide range of dietary approaches (low-fat to low-carbohydrate/ketogenic, and all points between) can be similarly effective for improving body composition.”

A day of eating, worked

An 80 kg (176 lb) lifter in a gaining phase whose maintenance is about 2,800 kcal a day. Maintenance is an estimate until the scale confirms it; start from any formula, then adjust by what two or three weeks of weighing show.

Line	Rule	Amount
Calories	maintenance +10 to 20%	3,080 to 3,360 kcal; start at 3,100
Protein	1.6 to 2.2 g/kg	130 to 175 g; take 160 g, 640 kcal
Fat	0.5 to 1.5 g/kg	40 to 120 g; take 80 g, 720 kcal
Carbohydrate	the rest, at least 3 to 5 g/kg	3,100 − 640 − 720 = 1,740 kcal, 435 g, which is 5.4 g/kg
Target	+0.25 to 0.5% a week	+200 to 400 g a week

Weigh in a few mornings a week and average. Gaining faster than 400 g a week for three weeks, cut 100 to 200 kcal. Gaining nothing for three weeks, add the same. That feedback loop is the method; the formula only gives you a starting point.

A cutting example would need different assumptions, including the lifter’s lean mass for the Helms protein range. The 80 kg bodyweight alone is not enough to calculate that target.

What the sources do not say

• They do not give a protein number per meal that you must hit; Iraki’s 0.40 to 0.55 g/kg per meal is a distribution that lets a day’s total work, not a window to chase.
• They do not say more than 2.2 g/kg hurts healthy people. Iraki points to the “lack of apparent harm over 1–2 year trials among lifters consuming protein intakes of at least 2.2 g/kg.” These findings do not establish a precise benefit cutoff for every individual.
• They do not endorse a supplement list. Iraki names four with evidence for lifters, creatine monohydrate at 3 to 5 g a day among them, and that is the extent of it. Nothing sold on this site or any other is required by these numbers.
• They do not tell you a diet type. Low-carb, high-carb, fasting windows: the ISSN stand’s position is that a wide range of approaches can be similarly effective when the deficit or surplus and the protein are in place.

The gallon of milk

Mark Rippetoe’s advice for new lifters on Starting Strength is famous for one line: a gallon of whole milk a day. In context it is narrower than its reputation. He prescribes it for “severely underweight young men,” says that “Not every trainee needs to drink a gallon of milk a day,” and that older lifters or those “already carrying a higher bodyfat percentage will probably not want that many extra calories.” His general point is the one the position stands make with numbers: “you have to eat and sleep,” and most people who stall on a novice program are not doing enough of either. That context should not be turned into a recommendation that every new lifter use the top of every range.

If you are running Starting Strength or GZCLP, the linear progression lasts as long as recovery does, and recovery is calories, protein and sleep. The learn hub has the rest of the beginner stage.
