I also love eating. if you can ,eet with nutritionist (possibly covered by healthcare insurance or student health centers).
Find regular easy to prepare foods that are your staple or base of food. I eat turkey, chicken, yogurt (plain no added sugar but add fresh or frozen fruit), and milk (skim or 1%). All easy to make and can be pretty tasty. This may be the hardest part, but finding healthy foods you also like will help greatly, so search the grocery store high and low.
Also this is tough.... give up booze for at least 6 weeks (it works but real hard). Remember all excess carbs get converted into fat for storage and you need to get to recommended daily amounts. Don't cut out all fat, just keep focused on the "good" fats in fish and nuts.
You can also google p90x nutrition plan. It is pretty easy and straight forward to follow.
