How do I know when I've planned in enough food for the day?
At the bottom of each food diary page you will find the totals for that day. You should aim to get as close to your 'target food and drink' total as possible.
Use your 'Weekly Summary' to balance the calories consumed with the calories burnt to make sure you don't exceed your daily calorie allowance.
Foods and drinks added to your diary add calories into your daily totals, activities burn calories and take calories from your daily totals.
Try to balance your 'week-to-date' calories by the end of the week to achieve a successful weigh-in.
