Macros 101: Understanding Carbs, Proteins, and Fats

Key Takeaways
- All three macronutrients are essential - protein for building/repair, carbs for energy, fats for hormones and vitamin absorption
- Start by simply including all three macros at each meal rather than obsessing over perfect ratios
- Focus on whole food sources for most of your intake, with flexibility for treats
Your body needs all three macronutrients. None are "bad" - they do different jobs.
#Protein (4 cal/g)
Builds and repairs tissue - muscle, skin, hair, hormones. Aim for 0.7-1g per pound of body weight if actively strength training (e.g. 105-150g for 150 lbs). Best sources: lean meats, fish, eggs, Greek yogurt, beans, lentils, tofu. A palm-sized portion at each meal plus one protein-rich snack usually gets you there - while whole foods are preferred, shakes are a convenient supplement when needed.
#Carbohydrates (4 cal/g)
Your body's main quick-energy source. Your brain uses ~130g of carbs daily just to function. Aim for 45-65% of total calories. Best sources: whole grains, fruits, vegetables, legumes. Simple carbs (candy, cookies, soda) are less filling and can spike blood sugar - base most intake on whole-food carbs.
#Fats (9 cal/g)
Absorb vitamins, produce hormones, protect organs. Aim for 20-35% of total calories. Best sources: avocados, nuts, seeds, olive oil, fatty fish. Eating fat doesn't make you fat - excess total calories do, from any macro.
#Myths Busted
- "Carbs after 6 PM turn straight to fat" - False. Total daily intake matters, not timing.
- "You need protein immediately after working out" - False. You have a several-hour window.

#Start Simple
- Include a protein source at every meal
- Don't fear carbs - choose mostly whole food sources
- Add healthy fats to keep you satisfied
Then: notice what you eat (no judgment), aim to include all three macros at each meal, optionally track for a few days. A rough sense of your macros is enough - the goal isn't perfection.
