Diet Tips

ok, i’m tired of doing fad diets. I have lost so much muscle and very little fat as a result. So i’ve decided to spend my summer working out and getting in shape. i’m currently 154 pounds and 5′3′ i do have a quite a bit of muscle. i want to weigh 124 which means i need to lose about 30 pounds. i want to get in shape before school starts. which is in 2.5 months.

i’ve decided to eat 6 small meals.
No soda
candy and sweets at a minimum.
avoid junk food as much as possible
eat mostly fruits, vegetables, lean meats
eat healthier carbs (ie brown rice instead of white.)

I also plan on working out for an hour and a half each day. for 6 days a week.
I will do tae bo 4 days. jog the 5th day and lift weights the 6th day.
is it possible to lose 30 pounds by September or at least 20 pounds?

i will also drink A LOT of water.
is it possible? and if not, what else can i do?
