I'll submit my two cents here.
1 - LEAN PROTETINS: Stay away from the Pork Sausage (high sat. fat content). Try going with canadian bacon or eggs white omelettes made of 4 - 5 egg whites and one whole egg for breakfast. Those are both good sources of lean protein. For lunch or dinner, the grilled chicken breast is a good idea. I would also add some fresh fish such as salmon, tuna, orange roughy (grilled or baked). Fish is a great source of lean protein as well as good fats.
And by powdered drinks, they mean whey protein shakes.
2 - FATS: Fish, as noted before, will give you plenty of essential fatty acids. So will legumes (garbanzo beans, kidney beans, etc.), nuts (walnuts, almonds, cashews - my favs) and flaxseed . Don't go over board on the nuts tho because they are calorie dense but a good rule of thumb is one handful a day.
You can also use all natural Peanut Butter or Almond Butter (put this on whole wheat toast or with some veggies)
3 - CARBS: I would watch out for those fruit cups, lots of sugar! Try whole fruit (bananas, berries, apples, oranges) & fresh veggies (carrots, broccoli, spinach, tomatoes, etc.). You can also have oats, brown rice, yams or whole wheat bread (I like sprouted breads because they are not made with flour). These are good complex carbs that digest slowly.
A quick example of each meal that I would eat:
Breakfast: 4 egg whites & 1 whole egg in an omelette with 1 cup of mixed vegetables, low-fat or FF cheese (1 slice or shredded), 1 tbsp milled flax, 1 slice sprouted w/w toast (sometimes i replace the flax with PB on the toast). 8 oz skim milk
Snack 1: 1 cup FF or LF cottage cheese, 1 small/med banana
Lunch: Turkey sandwich (3 slices of turkey breast, 2 slices sprouted w/w bread, 1 slice low-fat swiss, spinach & mustard). OR 4-5 oz lean poultry (chicken or turkey) & 1 cup mixed veggies)
Snack 2: 1 sandwich bag full of raw carrots, celery, grape tomatoes and either a palm-full of mixed raw nuts (almonds, cashews, walnuts) OR 1 3.5 oz package of tuna
Snack 3: Whey Protein shake (1 scoop of vanilla whey - 20g protein) with water
Dinner: 4 - 5oz of chicken (could go more), turkey, or fish (tuna, salmon, tilapia) with 1 cup steamed veggies & some olive oil/garlic). Sometimes I either bake the protein, grill on a foreman or stir fry everything in a small amt of sesame oil.
These are just some suggestions based on my normal day, feel free to vary it up. Hopefully, this helps you get on the right track. And whole foods are just natural foods that are not processed (LV's grocery list in the sticky is a great example of what is considered a whole food)
