To calculate your TDEE and macros split, provide your weight, height, age, gender, and activity level to compute total daily energy expenditure and target macronutrient ratios for your specific fitness goal.

You can look up USDA FoodData Central nutrition facts without a personal API key by using the DEMO_KEY fallback, which retrieves per-100g nutrition data and detailed FDC ID nutrient profiles automatically.

To find gym exercises by muscle group, filter the wger exercise database by category, equipment, or muscle name to retrieve detailed exercise instructions and key attributes.

You can estimate BMI, TDEE, one-rep max (1RM), macro splits, and body fat percentage offline using built-in pure Python formulas that compute deterministic body metrics without external API calls.

You do not need a USDA_API_KEY to retrieve food calories and macros; the skill uses the DEMO_KEY fallback to fetch per-100g nutrition facts and detailed nutrient profiles by FDC ID.

TDEE represents total daily energy expenditure including activity level, while BMR is the base metabolic rate at rest; the skill computes TDEE to calculate accurate macro splits for goal-oriented diets.
