Whole-food macros without the spreadsheet

There is a quiet truth most diet apps do not want you to figure out: the macros that drive 90% of your body composition outcomes are the two you barely have to track — protein and fiber. Hit those, and the rest of the meal can sort itself out.

This is not a free pass. Calories still matter; alcohol still matters; the kind of fat you eat still matters at the margins. But for the first six months of any diet change, the framework below outperforms a calorie-counting app for most adults — including the ones who think they are different.

The framework

Pick a target. Hit it daily. Stop measuring.

• Protein: 0.8–1.0 g per pound of bodyweight, every day. Spread across at least three meals.
• Fiber: 30 g for women, 38 g for men, every day. From food, not powders.
• Hydration: Half your bodyweight in pounds, in ounces of water, daily.

That is it. Three numbers. No app required.

Why these three

Protein

The studies that anchor the protein recommendation are remarkably consistent. Across a dozen trials in non-elite adults, intakes north of 0.7 g/lb beat lower intakes for lean mass retention during a calorie deficit. Above ~1.1 g/lb the returns disappear. The 0.8–1.0 range is where almost every adult should be living.

Practical translation: if you weigh 170 pounds, you are aiming for 135–170 grams a day. That is roughly:

1. A four-egg omelette at breakfast (~28 g).
2. Two chicken thighs and a yogurt at lunch (~50 g).
3. Salmon and a cup of cottage cheese at dinner (~45 g).

You will get there without thinking about it once the rotation is built.

Fiber

Fiber is the most under-prescribed lever in modern nutrition. The data on outcomes — cardiovascular events, all-cause mortality, glycemic control, even mood — is unusually strong, and the average American adult eats less than half the recommended amount.

Hitting 30–38 g without supplements is achievable but requires deliberate inclusion of:

• Beans and lentils (one cup ≈ 12–15 g).
• Berries (one cup ≈ 8 g).
• Whole oats (half a cup dry ≈ 5 g).
• Cruciferous vegetables (a serving ≈ 4–5 g).

Fiber is the most under-prescribed lever in modern nutrition.

Hydration

This one is boring and undermeasured. Most people are chronically a litre under. Fix it before you spend money on anything else.

The supplements worth recommending

We hedge on most supplements. We do not hedge on these two.

Common failure modes

• Eyeballing protein. Most adults underestimate by 20–30% until they weigh meals for a week. Do that once, then never again.
• Counting "added" fiber from bars. Isolated fiber additives do not produce the outcomes whole-food fiber does. Skip them.
• Front-loading protein then drifting. Hitting your number at breakfast and leaving the rest to chance leads to inadequate evening intake. Spread it.

Verdict

This is the framework we recommend before any diet app, any meal-prep service, and any premium nutrition coaching. It is simple, evidence-aligned, and it travels — it works on the road, on holiday, in restaurants, and on bad weeks. Start here. Add complexity only if you stall.
