Turn these numbers into a week of dinners and a grocery listHow this is calculated
BMR uses Mifflin-St Jeor (1990): 10 × kg + 6.25 × cm − 5 × age, plus 5 for men or minus 161 for women. TDEE multiplies BMR by the moderate factor (1.55). Lose subtracts 500. Gain adds 300. Floors are 1,200 calories for women and 1,500 for men. Balanced macros are 30% protein, 40% carbs, 30% fat. Gain muscle uses 1.8 g protein per kg when that is higher. Talk to a doctor before a big change.

Your questions
How does this calorie calculator work?
It uses Mifflin-St Jeor (1990) for BMR, then multiplies by an activity factor from 1.2 to 1.9. Lose weight subtracts 500 calories. Gain muscle adds 300. We never go below 1,200 calories for women or 1,500 for men.
Is this a food diary?
No. Carby is a budget dinner planner. This page is a free calorie number so you can pick dinners that fit. It does not log what you already ate.
Does this include grocery cost?
The calorie math is free and local. Estimated dinner cost uses Carby catalog ingredient estimates, not live shelf prices. Open the dinner budget calculator for a grocery number, then the budget meal planner for five dinners that fit.
How do I turn these numbers into cheap dinners?
This page is a free calculator. For a week of dinners and a grocery list, open the budget meal planner. Set a grocery number first with the dinner budget calculator if you want a cost cap.
