Sorry bro...I am a skimming reader and barely read anything over 5 words long.
To maintain your weight you need around 2,500-2,700 calories a day.
I recommend you download 'My Fitness Pal' onto your smart phone if you have one. You can even scan barcodes and it will store the calories into your diary so you don't have to search for it.
Buy:
1) Lots of tupperware/food storage devices
2) Cookie sheet/baking pan
3) Digital food scale (Walmart has them around $20)
3.5) Cup measurer...or whatever you want to call it. Thing that measures amount up to 1 cup or 2 cups+
4) Egg beaters (Southwestern Style ----- says it on the carton) LOTS of eggbeaters
5) If you're not into egg beaters (which are delicious by the way)...get you a ton of eggs in cartons...large eggs.
6) Huge carton of QUICK OATS
7) Whole grain Bagels...lots of them.
You have to cook your food ahead of time. Either the day before...or bake your chicken or prepare your food while cooking breakfast...or just in the morning.
Breakfast - Scramble your eggs and salt and pepper if desired:
(1.3 cups) - Egg Beaters
(1) - Whole Large Egg
(1.5 cup) - Skim milk (Drink water if you're still thirsty)
(1/2 cup) - Oatmeal (Add light brown sugar and/or small dab of butter for seasoning)
(1/2 cup) - Milk added to oatmeal
Calories - 540
Then you will eat 5 more times...8 ounces of the meat of your choice (Tuna, Steak, Chicken, Salmon, etc.)...they all come out to be around the same amount of calories. Red meat being about 100+ calories more per 8 ounces.
(8 oz.) - Boneless, Skinless chicken breast [240 calories]
(1) - Bagel [260 calories]
*500 calories
(500 calories x 5 = 2,500 calories [your maintenance level]) + (Your big ass breakfast of 540 calories) = 3,040 calories.
Dieting is VERY easy. It's very easy to gain weight if you can stick to it. Make sure you eat 1-2 cups of veggies a day. Whether it's green beans or whatever. Some fruit helps. Add that little bit to one of your meals for some extra calories and to keep your body healthy.
Take your multivitamins...keep eating (a lot obviously)...and WORK OUT! (or you will just get chubby/chubbier). Your muscle is synthesizing protein up to 48 hours after it has been fatigued (from what I have read)...so this is why you take in a ton of food throughout the week. To keep packing on weight, mass, muscle, whatever.
And don't be scared of a scoop of peanut butter during the day with a small glass of milk. That's adding good calories. Try to buy the peanut butter that is low in sodium & sugar.
