How to build a calorie budget
A menu is really a spending plan. You set a daily limit, choose foods you enjoy that fit inside it, and plan it all out before the week starts — so you're never caught without room or left hungry. Nothing is off-limits. It's all about tradeoffs.
How to build your budget
Find your daily calorie target
To lose weight you need to be in a caloric deficit — eating fewer calories than your body burns. Use the calculator below to estimate your maintenance level and get a target budget based on your actual goals. Protein matters just as much: it keeps you full and protects muscle while you're cutting. For most people aiming to lose weight, a good starting point is around 150g of protein per day.
Start with the sample menu
Don't start from a blank page. The sample weekly menu is a real week of eating — every meal planned out with calories and protein already calculated. Use it as your foundation. It shows you what hitting your numbers actually looks like day to day.

Swap out any meals you wouldn't enjoy and replace them with things you actually want to eat. But every swap has to balance: if you add a heavier meal, something else gets lighter. The total has to stay inside your budget. This is the budget method at work — tradeoffs, not restrictions. A great menu is one you actually look forward to eating.
Learn about food and cooking
The more you understand food, the easier budgeting gets. You'll discover which foods fill you up for very few calories — vegetables, lean proteins, high-volume meals — and which ones cost a lot for what they deliver. Learning to cook well is what makes low-calorie food taste great, and that's what makes this sustainable long-term.
Browse the food guidesKnow your portions before you plan
Before any food goes on your menu, you need two things locked in: how many calories are in a portion, and how you'll measure that portion. Guessing is what breaks a budget. Use a kitchen scale for items that matter. Know your visual anchors — 4 oz of chicken, a cup of rice, a tablespoon of oil. Decide how you'll measure something before you put it on the plan, not after it's already on the plate.
Other tips worth knowing
Learn to cook — and make food taste good
You don't need to eat bland food to lose weight. Learning to season, roast, and cook well means you actually want to eat the meals on your menu. That's what makes this work long-term.
Embrace trying new foods — some will surprise you
Some of the best additions to your budget are foods you've never tried. A lot of low-calorie foods are genuinely enjoyable once they're cooked right. Keep an open mind — your menu will get better every week.
Keep it diverse — rotate your greens and dinners
Aim for a different green vegetable every day of the week and a different dinner every day of the month. Variety keeps meals interesting, exposes you to a wider range of nutrients, and stops the menu from feeling like a punishment. If you find yourself eating the same five things on repeat, it's a sign to explore.
Use AI to plan and review your menu
ChatGPT and Claude are surprisingly good at this. Ask them to suggest meals that hit your calorie and protein targets, help you swap out a food you don't like, or review what you ate today and tell you where you landed. Treat it like a free nutrition assistant you can talk to any time.
Life happens — stay flexible
If you don't make a planned meal, move it — but don't re-plan the whole week. Skip it, freeze it, and move on. Stick to the plan unless you have a real reason to change it.
