Generally, aim to eat in roughly equal time intervals, spacing meals out evenly throughout the day. If extra snacks are needed they should be added where they will help the most such as post workout or to bridge a gap. If you have a regular schedule, simply identify what times you can eat breakfast and dinner, then schedule the rest of your meals and snacks evenly between.
Remember, food you haven’t eaten yet can’t fuel you. That means if hunger or energy is an issue, you might try eating more of your meals earlier in the day and closer together. This is also one of the reasons we like having breakfast shortly after waking and dinner at a reasonable hour.
When extra food is needed, you’ll find example snacks, “appetite control,” “energy” and “post workout” in the extra food screen. You can add individual macro’s there too.
