Nutrition

The building blocks — energy, protein, fat, carbs, fiber, and what actually fills you up.

Start here

Energy balance, plainly

Energy balance is the one rule that never breaks — what you store is what's left after intake minus expenditure. But expenditure isn't a fixed number sitting there waiting to be beaten; it quietly shifts as you eat differently, move differently, and lose or gain weight. This is why Kinra treats your target as a living estimate instead of a locked-in formula.

Protein: how much, and why it matters

Protein needs depend on your goal: a bit more than the bare minimum for general health, more if you're building muscle, and more still while cutting calories, since it may help you feel full and hold onto lean mass. The ranges below (roughly 1.6 to 2.2 g per kg of bodyweight) come from meta-analyses and sports-nutrition consensus statements, and they're the same logic Kinra's macro targets are built on.

Dietary fat, without the fear

Fat has spent decades as the diet villain, but it does real jobs in your body — and the research on saturated fat specifically is more nuanced than either "fat is fine" or "fat is dangerous" headlines suggest. This piece walks through what fat is for, what the evidence actually says, and why a roughly 20-35% of calories range is a reasonable place to land without chasing a single "optimal" number.

Carbs and fiber, sorted out

Carbs get blamed for a lot, but the science points somewhere calmer: total calories drive weight change, and the quality of your carbs — especially how much fiber and whole grain you're getting — matters more for long-term health than whether you eat carbs at all. This piece walks through the basics, examines the "carbs make you fat" myth, and gives simple, real-food ways to close the fiber gap most people have.

Feeling full: what actually satisfies

Not all calories feel the same in your stomach — protein, fiber type, food texture, and how minimally processed a food is all seem to change how full it makes you per calorie. This piece walks through what the research actually supports, what's overstated, and a few low-effort swaps worth trying.

Calories and how to read a food label

Food labels feel exact, but the number is a calculation with a built-in margin of error — and that's by design, not a defect. Once you know how labels are made and where the wiggle room lives, it's easier to log with confidence and let trends, not single entries, tell you what's working.
