Yepp it'll go, along side with decent routine at the gym.
I understand your position, with school and everything. With school in your days that'll make things easier to lose weight, as you can't just get up and walk to the fridge and eat anything lol. You'll be in lessons init! So your eating times are slotted, and with walking around also helps. I hope your walking to school.. and back ;)
I go to school, and I dunno I've never seen protein shakes as an option, thats a sorta thing for when your older and actually need it. As to when your doing hardcore workouts, you'll need the protein to help the muscle repair and develop. As you and I are both young, our bodies are still developing and shouldn't be over doing it anyway.
Weetabix is good too! So try and vary your foods a bit, be creative with what you eat, that'll make things less boring over time. And for dinner, jacket potatoe, fish, stuff like salad, theres loads of stuff to eat.
On a school&gym day my diets abit like:
7:45 - weetabix & milk - 200/250 calories maximum
11:00 - grapes & water from canteen - less than 50cals
01:30 - cumcumber sandwich usually, i'm a fussy eater. wholemeal bread, about 550 cals max.
03:15 - probably a banana, nutricious health bar, just something to eat
04:00 - gym
05:30 - finish gym
06:30-ish - (dinner) whatever mother/father cooks me, i spoke to them asking to support me and yeah, all going good they know what to cook. most of the time i pick out what i want though.
09:00 - yogurt/bar
10:00 - bed time, maybe an ovalteen, depends how i feel ;)
And drinking water throughout the day.
I wouldn't concentrate on getting lean AND losing weight. Lose weight first, focus on plenty of cardio, burn more calories than you eat in the day and your on a first class ticket to fatloss.
Like the guys suggested about keeping motiviated, they work a treat.
