fitness-nutrition

To calculate your TDEE and macro split for a cut, provide your weight, height, age, gender, and activity level. The tool uses offline Python calculators to compute total daily energy expenditure and target macronutrient ratios for your goals.

You can look up food calories and macros per 100g using the USDA FoodData Central database. It works with a free DEMO_KEY by default, or a higher-rate USDA_API_KEY if you provide one for nutrition tracking.

You can find gym exercises filtered by muscle group, equipment, or category by searching the wger database. It retrieves detailed exercise information from over 690 exercises for workout planning.

You can estimate your one-rep max and body fat percentage offline using pure Python stdlib calculators. It also computes BMI and body composition metrics deterministically without external network calls.

You do not need to provide an API key to use the USDA food lookup. It defaults to a free DEMO_KEY for lower rate limits, but you can supply a USDA_API_KEY for higher request volumes.

For workout planning, you can compute BMI, TDEE, one-rep max, body fat estimates, and goal-based macro splits. These offline health and training calculations use deterministic Python stdlib libraries.
