Make sure you've first generated a meal plan by tapping the ⚡ Generate button. Once a plan is active, you can ask the AI assistant to adjust it and the plan will update automatically above the chat.

Calorie and macro targets are calculated using the Mifflin-St Jeor equation, which uses your age, height, weight, and activity level. This is a widely-used method based on established nutritional science. Always consult a healthcare professional for personalised medical advice.

Go to the Settings tab in the app. You can update your weight, goal, activity level, and other profile details at any time. Your calorie and macro targets will recalculate automatically.

Try closing the app fully and reopening it. If the problem persists, check your internet connection — Hewett Health requires an active connection to load. If you continue to experience issues, contact us at michael-hewett@hotmail.com.
