How the model works
We calculate your Basal Metabolic Rate (BMR) and use this data to figure out how many calories you should eat per day.
Each answer fine-tunes the model to create an accurate plan for your body. From there we create easy to follow plans to follow over the course of a few months.
Every recommendation stays within science-backed ranges. We don’t create our own formulas. You’ll also receive gear suggestions tailored to your habits so you can build momentum immediately.
Frequently asked questions
Quick answers before you commit to a new routine.
Is this a replacement for medical advice?
No. Treat the plan as a starting point for conversation with a licensed professional, especially if you have existing health conditions.
How accurate are the calorie targets?
They use evidence-based formulas and behavioral modifiers. Still, your body is unique—adjust based on progress and feedback from your healthcare provider.
Why do you recommend equipment?
Tools like scales, containers, and trackers make it easier to track your goals. We don’t recommend any “magical” weight loss supplement.
Can I rerun the assessment later?
Absolutely. Revisit anytime your goals chang. Updating your answers instantly recalculates the plan.

Frequently Asked Questions (FAQ)
What is a calorie deficit?
A calorie deficit is the simple principle of consuming fewer calories than your body burns in a day. When your body needs more energy than it’s getting from food, it starts using its stored energy (fat), which leads to weight loss. This calculator helps you find a safe and effective daily calorie target to achieve that deficit.
How does this calculator determine my maintenance calories?
It starts by calculating your Basal Metabolic Rate (BMR)—the number of calories your body needs to perform basic life-sustaining functions, like breathing and circulation. Then, it factors in all the information you provide—your job, exercise habits, and daily steps—to estimate your Total Daily Energy Expenditure (TDEE), which is your total “maintenance” calorie number.
Why are the plans based on losing 1-3 pounds per week?
Sustainable weight loss is a marathon, not a sprint. Losing 1-2 pounds per week is widely recommended by health experts as a safe and manageable rate. Losing weight too quickly can lead to muscle loss, nutrient deficiencies, and fatigue. Our AI recommends a plan that best fits your current body composition (BMI) for the safest, most effective results.
How accurate is this calorie calculator?
While this calculator is one of the most comprehensive tools available, it provides a highly accurate *estimate*. Every person’s body is unique, and metabolism can vary. The number provided is an excellent scientific starting point. We recommend using it for 2-3 weeks and adjusting your intake slightly based on your results.
What is BMI and what does my result mean?
BMI stands for Body Mass Index. It’s a measure that uses your height and weight to gauge whether your weight is healthy. The categories (Underweight, Normal, Overweight, Obese) help provide context for your health and are used by our AI to recommend a safe rate of weight loss.
Can I lose weight without exercising?
Yes, weight loss is primarily determined by a calorie deficit, which can be achieved through diet alone. However, incorporating exercise is highly recommended. It helps you burn more calories (allowing you to eat more while still losing weight), build and maintain muscle, and improve your overall health and well-being.
What should I do if I hit a weight loss plateau?
Plateaus are a normal part of any weight loss journey. They can happen for many reasons, including your metabolism adapting to your new weight. You can often break through a plateau by slightly adjusting your calorie intake, changing up your exercise routine, ensuring you’re getting enough sleep, or taking a short diet break at your maintenance calories.
