I'm 23 and clueless about health. I was blessed with a high metabolism and didn't ever gain weight growing up (5'6/135 at HS grad, 5'6/138 at college grad) despite a horrible diet and no exercise other than walking a mile per day to class. I'm trying to get better now, though my only real concern is getting fat; I don't care about being muscular.
I'm not sure if I should be focusing on low calories, carbs, and/or fat to stay skinny. I kept track of my calorie intake for two weeks, and I was allotted almost 1800 calories per day but only averaged ~1350. My weekly diet is very consistent because I'm lazy and picky...
- 2-3 footlongs at Subway (ham, lettuce, and tons of tomatoes on wheat)
- 1-2 meals at a Chinese place (pint of chicken fried rice)
- 1 12-nugget pack at Chick-Fil-A
- 3 Lean Cuisine Pizzas
- The remaining 14 meals are mostly Oscar Meyer pre-cooked chicken strips
- Snacks: three bananas, a bag of baby carrots, six Dr. Peppers, a couple Bud Lights, 1-2 bags of pretzels, a lot of Atomic Fire Balls, and a ton of water.
If my goal is merely to keep off belly/body fat, are there any major changes I need to make to my diet? Is there anything that should absolutely be cut out or included? I'm also getting back into running. Is there a target number of miles/burned calories I should be aiming for each week? I realize this is super specific, but I'm absolutely clueless when it comes to EVERYTHING.
