Is this a medical nutrition plan?

No. It is a planning calculator, not medical advice.

Why is protein based on body weight?

Using body weight makes the target practical and easy to adjust.

Can I change the calorie target?

Yes. The calorie field is the main driver of the carbohydrate budget.

Does this account for activity level?

Not automatically. You choose the calorie target, and the calculator splits it into macros.

Daily Macros

—

Protein (4 Cals / Gram)

The building block of muscle. Essential for repairing tissue after a workout and highly satiating, meaning it keeps you feeling full longer than any other macro.

Carbohydrates (4 Cals / Gram)

Your body's preferred and most efficient energy source. Carbs fill your muscles with glycogen, allowing you to lift heavy and sustain high-intensity cardio.

Fats (9 Cals / Gram)

Essential for hormone production (like testosterone), brain function, and joint health. Because fats are dense, a small amount carries a massive caloric footprint.

Can I eat junk food if it fits my macros (IIFYM)?

Technically, yes, but practically, no. If your goal is 150g of carbs, you could eat a massive bowl of sugary cereal. However, you will immediately spike your insulin, crash an hour later, and feel starving for the rest of the day because you missed out on the fiber and micronutrients found in complex carbs like sweet potatoes or oats. Treat 80% of your macros as fuel from whole foods, and 20% as fun.

Do I weigh my food raw or cooked?

Always weigh your meat and carbohydrates RAW before cooking. Chicken breasts lose a massive amount of water weight when grilled, and pasta triples in weight when it absorbs boiling water. The nutritional databases in apps like MyFitnessPal are almost entirely based on the raw, uncooked weight.

What happens if I miss my macros by a few grams?

Absolutely nothing. Do not stress over 5 grams of fat or 10 grams of carbs. Human biology is not a calculator. Aim to hit your protein goal every day (as your body cannot store protein for later use), but allow your fats and carbs to fluctuate slightly depending on your hunger levels and activity for that specific day.
