There is no right or wrong meal plan -- only the one that works for you. Look at your schedule and how meals and snacks fits in. Many people do best eating every 4-5 hours. If you eat breakfast at 7 am and can't eat lunch until noon, you may be alright with a bigger breakfast balanced in healthy fats, whole grains and protein so you are not hungry by 10 AM. If your breakfast is more whole grain based and smaller and burned up by 10 AM, you may need a snack to get you through.
Same holds true in the afternoon. If a larger lunch gets you to dinner without being hungry and wanting junk food out of the vending machine, go with it. If you are always hungry at 4:30PM and dinner is still hours away, a snack in in order.
Take the nutrient/calorie allowance you have and find out how it will work best to consume them throughout the day. You don't really have to "cut out" anything, just adjust portion sizes and meal and snack selections.
