Your Healthy Nutrition Plan in the Healary app is made up of Balanced Days, with the option to incorporate a Treat Day. On Balanced Days, you're advised to minimize your intake of yellow and red foods. Meanwhile, a Treat Day offers you the freedom to indulge in any food without restrictions. To modify your Healthy Nutrition Plan, simply tap the edit icon on the Healthy Nutrition panel and choose Adjust Nutrition Plan. From there, you can set each day of the week as either a Balanced Day or a Treat Day. Keep in mind, you can assign only one Treat Day per week.
