MyFitnessPal

Calculates personalized daily calorie and macronutrient targets based on biometric data and fitness goals. Returns daily calorie target adjusted for weight goal (lose/maintain/gain), macro breakdown (protein, carbs, fat in grams), meal-specific targets for breakfast/lunch/dinner, and TDEE. Requires age, sex (male or female), height (with unit: inches or cm), weight (with unit: lb or kg), activity level (sedentary/lightly_active/moderately_active/very_active/extremely_active), and weight goal. If weight goal is not explicitly stated, ask whether they want to lose, maintain, or gain weight - do not assume 'maintain'. Optional: diet speed (slow/moderate/aggressive, defaults to moderate) and dietary approach (keto, vegan, paleo, highProtein, etc.). The calculated goals can be used by search-recipes to filter recipes matching the user's nutritional targets.

calculate-goals

Searches 1500+ recipes with nutrition information and returns an interactive widget with photos, ingredients, instructions, and nutrition facts. Filter by keywords (specific ingredients like 'chicken', 'salmon' - not generic terms), meal type (breakfast/lunch/dinner), recipe type (salad, soup, pasta, taco, burger, sandwich, pizza, etc.), dietary approach (keto, vegan, paleo, high protein), nutrition ranges (calories, protein, carbs, fat per serving), cuisines, allergens (dairy, egg, fish, gluten, etc.), ingredient dislikes (onions, mushrooms, etc.), or cooking time. Can also modify recipe serving sizes when recipe_id is provided. Use recipe_id from widgetState.selectedRecipeId when user says 'adjust this recipe', 'make this for 6 people', or 'double this' while viewing a recipe in fullscreen. The widget displays all recipe details automatically. List recipe names only in your response - do not offer to show ingredients or nutrition information as the widget already displays everything. The tool's content field includes a follow-up question about calculating nutrition goals - include it in your response.
