Instead of depriving yourself of food because you have finished your calorie budget for the day, learn how to plan them.
The first thing to consider is how much food you want per meal, or do you prefer to eat small amounts but more frequently?
Once you have considered that, know what activities you will be doing. Does it require you to have more or fewer calories? Remember how to compute the recommended calories you need depending on how you will be moving.
Then you can now break down your budget. This will help you manage your food choices while feeling full for the whole day.
