Protein has become one of the most-discussed numbers in nutrition in 2026, and a January 2026 revision to the federal government's own dietary guidance is a big part of why: the 2025–2030 USDA/HHS Dietary Guidelines for Americans raised the general recommended protein range to 1.2–1.6 grams per kilogram of body weight per day — well above the 0.8 g/kg figure that still shows up as the default on many older protein calculators. Below is what changed, why the old number persists, and a calculator that uses the updated range.
How much protein do I need — the old number vs. the new one
The 0.8 g/kg figure is the Recommended Dietary Allowance (RDA) — defined as the minimum intake that prevents deficiency in a generally sedentary adult, not an optimal target. It's the number that's been printed on nutrition labels and cited by default calculators for years. The updated 2025–2030 guidelines instead point to a broader 1.2–1.6 g/kg range for the general adult population, roughly 50–100% higher than the old minimum.
Why activity level changes the number further
Sports nutrition research narrows the range further by activity level: roughly 0.8–1.0 g/kg for someone with minimal physical activity, 1.0–1.4 g/kg for moderate activity (exercising 2–3 times a week), 1.2–1.7 g/kg for regular activity (4–5 times a week), and 1.4–2.0 g/kg for very active people training daily or working a physically demanding job. A 70 kg (154 lb) moderately active adult, for example, lands at roughly 70–98 grams a day under this range — noticeably higher than the 56 grams the old flat 0.8 g/kg RDA would suggest for the same person.
Why protein tracking is often behind a paywall
Several widely used nutrition and protein-tracking apps put core logging features behind a paid tier — user reviews describe barcode scanning, daily repeat-logging, and home-screen widgets moved to subscriptions running $26 to $79.99 a year, with free tiers left showing ads between screens. For someone who just wants to know how many more grams they need today, that's a lot of friction for one number.
A protein calculator with no sign-up
Our protein calculator uses the activity-based range above — enter your weight and activity level to see your target range, then log today's intake from six common high-protein foods (chicken breast, eggs, Greek yogurt, salmon, tofu, protein powder) to see a running total against that range. No account, no paywalled features, nothing to unlock.
