yeah, i've been trying to shed some pounds too. but i haven't been successful because i messed up my schedule and i just started anyhow here are some tips my "trainer" told me. he used to weigh 210 and he's 5'5 1/2.
1. same idea as what lavelle said, but no carbs after 4pm. no eating at all after 8pm. (this is where i screwed up)
2. be smart about what you eat. you can have 1 cheat day a week (this is also where i screwed up)
3. Don't mean to yell but, MAKE SURE YOU EAT BREAKFAST! it's extremly important! this will kick start your stomach and help your metabolism. i've noticed weight loss after a bit. you feel better too
4.any sort of cardio at least 4-5 times a week for at least 30 min.
5. if you have the time and energy, calorie count. make sure you burn more than you consume.
yeah being stressed out helps too, but if you're like me you're more likely to gain than to lose. and besides stress kills
i think that's about it, i don't want to turn this into an essay. good luck
