I wouldn't be only eating one meal a day, in fact I plan on eating 3 meals a day, just smaller

My school has a meal plan that gives you so many meals per week (like 21, 15, 10, 5...), and I plan on using the 10 meals a week meal plan so I'll have one meal a day from the school, and for the other two meals I'll have to buy groceries and make them myself. I'm doing that so that I have more control over what exactly I'm eating and how much I'm eating.
The school cafe is a buffet type thing and you can get as much as you want as long as you're in the cafeteria, and I tend to have a hard time keeping the size of the meal down and their healthier foods usually aren't things that I like....
We'll see how it goes
