Question 1

What macros should I eat to lose weight?

Accepted Answer

Weight change is set by calories; macros set how the change feels and what it's made of. In a deficit, prioritize the protein end of the ranges (25–30% of energy) to protect muscle and manage hunger, then split the remainder between carbs and fat by preference.

Question 2

How many grams of protein, carbs, and fat do I need?

Accepted Answer

At maintenance, the balanced split gives most adults roughly 1.6–2.2 g protein per kg only at high percentages — this page shows your exact grams for each split at your calories, which beats any generic rule of thumb.

Question 3

Are these splits inside official guidelines?

Accepted Answer

Balanced and higher-protein sit fully inside the IOM AMDRs. Lower-carb sits below the 45% carbohydrate floor and is labeled as such — popular, but outside the reference range by design.

Question 4

Do I need to hit macros exactly?

Accepted Answer

No. Daily ±10 g noise is irrelevant. Weekly averages near the targets — with protein the one you track most closely — deliver everything the precision theater does, with far less burnout.

Question 5

Why grams instead of percentages?

Accepted Answer

You can't eat a percentage. Grams map to food labels and portions; that's also why the next step here is a plate: the MyPlate Plan converts the same calories into food groups you can actually shop for.

Question 6

Do these macros change if I'm cutting or bulking?

Accepted Answer

The percentages can stay; the calories change. Set your target with the calorie-deficit calculator (or add a modest surplus), then apply the same split to that number — protein in absolute grams should stay high while cutting.
