Frequently asked questions

How does Muscle Booster Nutrition work?

During onboarding, you set your nutrition preferences, like a diet, allergies, or the time you can spend cooking. Each day, you get an adaptive daily card (fasting timer or live calorie view depending on your input), AI-assisted logging, and a calorie tracker that ties into your training goals. Your daily calorie and nutrient targets are personalized and calculated based on your age, weight, height, and level of physical activity. Meal suggestions are available as an optional paid upgrade.

Should I choose fasting or calorie tracking?

You can pick either as your starting emphasis — both are always available. Choose fasting if you want a structured eating window; choose tracking if you prefer a calorie-first approach. You can switch at any time.

How do meal suggestions work?

Meal suggestions are context-aware: they factor in time of day, your preferences/allergies, recent meals, and cook time. The app shows three options with macros so you can pick what fits your plan and log it with one tap. All meals are picked by Muscle Booster nutrition and fitness experts.

Is Nutrition included in my subscription?

Yes — Nutrition is built into Muscle Booster's core experience. Meal recommendations are an upsell and are not included in all subscriptions.
