Immediate lifestyle change, good or bad?!

Immediate lifestyle change, good or bad?

used to (from 2006-to-recently): eat all the time, eat whatever i want, never really went outside for over a year, never ate healthy, never ate fish or fruits and veggies, never exercised for over a year, sit down in front of a computer for 9 hours a day. (5'10", 195 lbs) (bmi of 28, considered overweight)

i now: eat subway everyday, eat only when hungry (3-4 times a day), no longer eat anything unhealthy, power walk 2-4 miles everyday, have about 20-40 minutes of tae-bo everyday, lift weights for about 30 minutes every day, take 2 green tea weight loss pills every day, eat fruits and grains.

i am going for losing 45 lbs by the last week of august.

too much, or just right? i feel exhausted everyday, but i really cant stand being fat anymore. its destroying my selfesteem and my ability to get in a pool and get a girl or guy.

im not fat, fat...i just look funny with a shirt off.

awesome...way to go...your taking controll of your life instead of Mcdonalds. you will see a lot of health benefits within a week of your changed diet...more energy, more confidence, more stamina, and just a better overall life...congratulations man!!!
