Meal Plan

I have not followed a plan and I am not sure if I can.  I did well not long ago.  I ate healthier and lost some weight.  Now I shouldn't be surprised if I have gained weight.  I realize that even if I am not hungry, I need to eat breakfast and eat a lighter lunch and an even lighter dinner.  Also, it would not hurt if I were to consume what foods and at what time.  Adding water and other drinks would not be a bad thing as well.

An example menu plan for a sample day would look like this:
7:30-8:30  Yogurt with honey
9:00-9:30   Apple
11:00-1:00 Macaroni and cheese, chicken, broccoli
2:00-2:30   Celery with peanut butter
3:30-5:00   Macaroni and cheese
6:00-7:00   Pineapple
8:00-8:30   Handful of peanuts

Should I do this at all?  These are approximate eating times or should I do this?

Breakfast
7:30-8:30 AM  Yogurt with honey
Snack 1
9:00-9:30 AM   Apple
Lunch
11:00 AM - 1:00 PM  Macaroni and cheese, chicken, broccoli
Snack 2
2:00-2:30 PM Celery with peanut butter
Dinner
3:30-5:00 PM  Macaroni and cheese
Snack 3
6:00-7:00 PM  Pineapples
Snack 4
8:00-8:30 PM  Handful of peanuts

I like the second one better since it is actually specific and it is a good way of tracking what I eat, how I eat, and when I eat.
