Aqua values mark the highest in each column. "P/Cal" is grams of protein per 100 calories — higher is more protein-dense.

The Big Picture

Macronutrients vs. Micronutrients

Macronutrients ("macros") are the three nutrients your body needs in large amounts and that provide energy: protein, carbohydrates, and fat. They show up on every food label.

Micronutrients ("micros") are vitamins and minerals — needed in much smaller amounts but essential for nearly every body process, from immune function to bone health to muscle contraction.

Both matter. You can hit your macros perfectly and still be deficient in iron or vitamin D. You can eat plenty of micros but under-eat protein and lose muscle. The goal is balance.

The Three Macros
Protein
4 cal / gram
Builds and repairs muscle, supports immunity, keeps you full longer.
SOURCES: chicken · eggs · fish · greek yogurt · cottage cheese · lean beef · tofu · lentils · whey protein
Carbs
4 cal / gram
Primary fuel for training. Powers the brain. Restores muscle glycogen.
SOURCES: oats · rice · potatoes · sweet potatoes · fruit · whole grain bread · quinoa · beans
Fat
9 cal / gram
Hormone production, vitamin absorption, joint health, long-burning energy.
SOURCES: olive oil · avocado · nuts · seeds · fatty fish · eggs · cheese · nut butters

Note: alcohol provides 7 cal/gram and is sometimes called the "fourth macro," but it's not nutritionally essential.

The Key Micros

What active people often miss

Training puts extra demand on certain micronutrients. These are the ones most commonly underconsumed by athletes and gym-goers:

  • Iron — oxygen transport, energy. Found in red meat, spinach, lentils, fortified cereals.
  • Vitamin D — bone health, hormones, immune function. Found in fatty fish, egg yolks, sunlight, fortified dairy.
  • Magnesium — muscle function, sleep, recovery. Found in dark chocolate, almonds, pumpkin seeds, leafy greens.
  • Calcium — bone strength, muscle contraction. Found in dairy, sardines, kale, fortified plant milks.
  • Potassium — fluid balance, muscle cramping. Found in bananas, potatoes, beans, avocado.
  • B vitamins — energy metabolism. Found in whole grains, eggs, meat, leafy greens.
  • Zinc — recovery, immune function. Found in oysters, beef, pumpkin seeds, chickpeas.
  • Omega-3s — joint health, recovery, brain. Found in salmon, sardines, flaxseed, walnuts.

If you eat a varied diet rich in vegetables, fruits, lean proteins, whole grains, and healthy fats, you'll likely cover most of these. Specific deficiencies should be confirmed by blood work, not guessed at.

Frameworks

USDA MyPlate

MyPlate is the U.S. government's general healthy-eating framework. It replaced the old food pyramid in 2011 and emphasizes filling half your plate with fruits and vegetables, a quarter with grains (mostly whole), a quarter with protein, plus a serving of dairy or fortified alternative.

It's a good starting point for most people who don't have specific athletic or medical needs. Learn more at myplate.gov.

Hand-portion guidelines

If counting calories isn't your style, use your hand:

  • Palm = one protein serving (~3-4 oz / 20-30g protein)
  • Cupped hand = one carb serving (~1 cup / 30-40g carbs)
  • Thumb = one fat serving (~1 tbsp / 10-15g fat)
  • Fist = one veggie serving (~1 cup)

Most active women aim for ~1 of each per meal, most active men ~1.5–2.

Heads up: Calculator outputs are general estimates based on standard formulas. They are not medical advice. Real metabolic rates can vary by 10-20% from these numbers. Consult a Registered Dietitian for personalized targets.

Calorie Calculators
BMR — Basal Metabolic Rate
Calories your body burns at complete rest in 24 hours
Your BMR cal/day

Calculated using the Mifflin-St Jeor equation, the modern standard. This is the energy needed just to keep your body running — breathing, circulation, basic cell maintenance — if you stayed in bed all day.

TDEE — Total Daily Energy Expenditure
BMR adjusted for your activity level — your daily maintenance calories
Your TDEE cal/day

This is roughly what you'd eat to maintain your current weight at your current activity level. Eat consistently below it to lose weight, above it to gain. Adjust based on real-world results over 2–4 weeks.

Macro Split (general guideline)
Protein / Carbs / Fat Targets
Based on your TDEE and goal — a starting point, not a prescription
Daily Calorie Target cal
Protein
grams
Carbs
grams
Fat
grams

Protein set at ~1g per pound of bodyweight (a common athletic target), fat at ~25% of calories, carbs filling the rest. There's a wide range of valid splits — this is one reasonable starting point.

If any of this feels wrong or impossible to hit: the numbers are an estimate, not a rule. Most people do better starting with a small adjustment from what they currently eat (track for a week, then change one thing) than with a calculator-prescribed jump.
