Nutrition plan builder with macro targets
Turn a short questionnaire into daily calorie, protein, carb and fat targets and a menu your client can follow — general healthy-eating guidance for healthy adults, fully editable.
Targets you can explain
Energy needs are estimated with the Mifflin-St Jeor equation, or Katch-McArdle when body-fat percentage is known, and an activity factor. Protein is set in grams per kilogram by goal, fat has a healthy minimum and carbohydrates make up the rest. The app shows every calculation step, plus daily fiber and water.
- Goals from fat loss to muscle gain, each at a gentle, moderate or faster pace
- Safe limits: a capped daily deficit and a minimum calorie floor
A daily menu from real foods
Menus are built from 121 foods with household portions and 44 ready meals, in three to six meals a day. Each meal can have up to three interchangeable options, all matched to the same target, with live totals as you edit.
Eating styles and food preferences
Choose a balanced, Mediterranean, high-protein, vegetarian or vegan style, or start from one of eleven menu templates. Foods are tagged for common allergens such as gluten, nuts, dairy, eggs, soy and sesame. A kosher mode never mixes meat and dairy in one meal.
Guidance, not therapy
Nutrition in ChallenGYM is general healthy-eating guidance for healthy adults. It is not a diet, not medical nutrition therapy and not a substitute for a registered dietitian or a doctor. Coaches should stay within their scope of practice and refer clients with medical conditions.
