Frequently Asked Questions
How many calories do I burn a day?
This is your TDEE (Total Daily Energy Expenditure). It combines your BMR (Basal Metabolic Rate) with your activity level. Knowing this number is the first step to weight loss or muscle gain.
What are the best macros for fat loss?
Research suggests that a high-protein diet helps preserve muscle mass and increases satiety during a calorie deficit. Our "High Protein" option adjusts your ratios accordingly.
Is "Lower Carb" safe?
Yes. Our Metabolic option provides ~30% carbohydrates, which is enough for brain function but low enough to improve metabolic flexibility without strict Keto risks.
