It should be quite easy to get up to 3000
calories in a healthy and sustainable way.
Here's just one example of how you might do it:
Breakfast: Full
fat Greek yogurt with honey and almonds and some kind of fruit (banana, apple, blueberries, strawberries, whatever (560
calories)
Snack: 2 T of peanut butter on a slice of whole grain bread (320
calories)
Lunch: whole wheat pita with turkey, cheese, and various mixed veggies, drizzled with Italian dressing made with olive oil and vinegar and spices; a glass of low
fat milk or a serving of low-
fat cottage cheese on the side; (625
calories)
Snack: couple of boiled eggs and a can of tomato juice or v8, another handful of almonds (about 14 or so - 1/2 serving) (380
calories)
Post workout: scoop of protein powder in 8 oz of orange juice (280
calories)
Dinner: 6 oz of grilled chicken (2 servings), a baked sweet potato with a tiny bit of butter, a medley of grilled or roasted veggies drizzled with olive oil and balsamic vinegar (600
calories)
That's 2765
calories and gives you some leeway for a little more olive oil or a few more almonds or even (if you wanted to treat yourself a little) a bag of baked chips with your lunch.
Here's another:
Breakfast: 2 T of peanut butter and a sliced banana on a slice of whole grain toast (430
calories)
Snack: whole wheat pita spread with hummus and topped with 1/2 a tomato, sliced (400
calories)
Lunch: stir fried veggies in a bit of olive oil with some kind of lean protein (grilled chicken, shrimp, fish, whatever) over brown rice (550
calories)
Snack: an apple sliced up and drizzled with honey, a serving of almonds (370
calories)
Post workout: scoop of protein powder in 8 oz of orange juice (280
calories)
Dinner: a hamburger on a whole wheat bun, made with 4oz lean ground beef and topped with lettuce, tomato, relish, mustard, etc.; cole slaw made with cabbage, carrots, and some kind of vinaigrette; oven baked fries (610
calories)
Late night snack: airpopped popcorn (150
calories) or a skinny cow ice cream sandwich (150
calories)
That's 2790 and again, leaves you a little leeway for additional dressings or mayonnaise on the burger, or another slice of bread for a full sandwich in the morning ...
There are a ton of ways to mix and match the most basic of foods in order to get to the
calories you need. And then as you need to lower your
calories, you can lower amounts and cut out the extras (like the fries with dinner, or whatever).
Edited to add: I put the post work out snack before dinner, because that's when I work out - right after work, before going home for dinner. You could easily move that snack to whatever time of day you exercise. If you work out first thing in the morning, then have that snack immediately after you finish and then have breakfast about an hour or so later, if you can. You also don't have to have meals and snacks. You can eat a steady amount all day, or you an have 3 meals and no snacks. You can always tweak and move things around - this is just the way I prefer to eat.
