I am a 17.5 y/o and i'm trying to lose some weight. I currently weigh 190 lb/86.1825 kg and am 5ft 10in, my goal is not really to build a large amount of muscle mass, I just want to stop looking so tubby in the stomach area.
Currently i eat around 3 to 4 smallish meals a day. For breakfast it is usually an apple and a nutrigrain bar. For a Lunch i have a sandwich and a small amount of almonds. Then in the afternoon i usually eat a nutrigrain bar, yogurt, and another apple. Then finally for dinner i usually have pasta or something of the variety with chicken or steak. For drinking i drink around 1.5 to 2L of water each day and have a glass of milk with dinner. I don't take any of the supplements cant afford them.
For exercise I do 5k a day after i get home from school. I do the 5k in anywhere from 27 to 30 minutes. Then after dinner i usually do about 50 push-ups and about 100 sit-ups. I cant afford a gym membership and I have no real exercise equipment i have to do everything on my own.
I am new to this kind of stuff and i was just trying to figure out if this is healthy, and right now i have taken off 3 pounds a week for the past 3 weeks following this guide and I am just checking to see if this is a good idea at all.
