Good nutrition is not a list of forbidden foods — it is a system you can actually run for years: enough protein, a smart calorie deficit, and meals you genuinely enjoy. This hub collects all our nutrition articles: protein and hydration targets, deficits without hunger, snacks, supplements, and popular myths debunked.
Every article is editorially reviewed and based on mainstream scientific guidance. Start with the basics — and calculate your personal calorie target with our free calculator.
CALCULATE YOUR CALORIE TARGETIn an NIH clinic, people were fed two diets matched for calories, sugar, fat and fibre. On the ultra processed one they ate about 500 more calories a day — and never noticed. Here's what actually counts as ultra processed food, how to identify it from the label in ten seconds, and why \"just eat less\" works worse here than it sounds.
Fibermaxxing — 2026's trend of deliberately maxing out fiber — is that rare case where doctors side with TikTok: 90–95% of people in Western countries fall short of the target. Here's what fiber actually does according to the research, how to build a 30-gram day from normal foods, and the caveats influencers skip.
A gym-lore classic that turned out to be true — with footnotes. We break down the overnight studies: how much cottage cheese it takes for muscle to grow while you sleep, and why it won't make you fat.
The number is catchy and the research is real, but there are serious caveats in between. Here is the honest version: what was measured, how choline fits in, and what actually lowers dementia risk.
Counting calories means writing down everything you eat and drink and adding up the energy using numbers from labels and a food database. In the first month a food log takes about 23 minutes a day, and by the sixth month about 15. Below: seven steps from scratch, a raw-to-cooked table showing what a mix-up costs on your plate, what your hand can really do in place of a scale, how to keep a food diary and when it's time to stop counting.
In a large survey of college students, 97% of women and 68% of men said they get cravings for specific foods. If you crave sweets all the time, two or three plain causes are usually behind it: short sleep, long gaps between meals, stress, habit, and for women the last days before a period. We go through each one with numbers from the research, answer what your body is really missing, say when to see a doctor and give you a plan.
A calorie deficit means eating less than you burn, and eating 15–20% less is enough to lose weight. We walk through the math in three steps with a worked example, show how much you'll lose per week at different deficits, how to cut 300 calories from everyday food and how to check your number after 4 weeks.
The standard adult intake of vitamin D is 600 IU (15 mcg) a day, and 4,000 IU a day is the upper limit for healthy adults. In a Russian study of 996 adults, 84% tested below 30 ng/ml in spring and 62% in autumn. Below: how much to add based on your 25(OH)D result and body weight, food amounts in grams and ounces, how three major guidelines read the same lab number, and what a supplement won't do.
How much protein you need per day depends on your weight and goal: from 0.8 to 2.2 g per kilogram. Inside: a ready-made chart for 50–110 kg (110–243 lb), protein in everyday servings, two food baskets that add up to 120 g and a simple way to split your target across meals.
Within 1-2 hours after a workout, eat 20-40 g of protein plus a serving of carbs. Before it, have a normal meal 1-4 hours out or a light snack 15-60 minutes out. Below: grams by your body weight, the 3-4 hour rule between meals, fasted training, eating at night, and what changes if you're cutting or building muscle.
A weight-based target: about 30–35 ml (roughly half an ounce per pound) of fluid a day, counting tea, coffee, soup, and the water in food. At 154 lb (70 kg) that's 2.1–2.45 L (71–83 oz). Below: a table by weight, why the US, European, and Russian guidelines disagree, whether coffee counts, how much to drink during and after a workout and in the heat, dehydration signs, and how much water is actually too much.
The plate method keeps protein, veggies, and carbs in balance by eye — no food scale, no tracking apps. Here's how it works and how to start today.

An adult needs at least 130 g of carbs a day, and if you train, the working range is 3–5 g per kg of body weight (1.4–2.3 g per lb). We explain why the numbers online don't match, calculate carbs for four people with three goals, and turn grams into real food.
Fat doesn't make you fat by itself — you need it for hormones, your brain, and vitamin absorption. Here's which fats to choose and how much per day.

You don't have to quit sugar completely. Here's how much is actually fine, where sugar hides in everyday foods, and which swaps work without misery.
Your body needs salt, but most people eat far more than the limit, often twice as much, and most of the extra comes from sausage, bread, cheese and restaurant food.

Creatine is stored in your muscles and fuels the first seconds of hard effort. Supplementing raises those stores by 20–40% and improves performance in short, powerful efforts by 10–20%. Here's dosing with and without a loading phase, how to scale the dose to your body weight, how much meat equals one serving, kidneys and creatinine on a blood test, water weight, and who won't get much from it.
Protein powder is dried milk or plant protein. If you train, you need 1.4–2.0 g of protein per kilogram of body weight a day, and powder only helps when food falls short. Inside: what a scoop adds in numbers, how many you need at your weight, what replaces it in food (25 g of protein = 81 g of chicken breast), which type to buy, and how to read the label after an audit found problems in 17 of 18 brands.

The glycemic index gets printed on labels and built into entire diets. Here's what the number really tells you — and when you can safely ignore it.
