Hi guys, my weight is 76kg with a height of 165cm. Currently age 23. My bmi is already considered as overweight. I'm really worried that I will be obese when I start working. Any similar case with mine that has successfully lost weight?

My current diet is
Breakfast - Biscuit/Bread with kaya with a cup of Nescafe or Tea
Lunch - White rice with gravy + Chicken + sometimes egg
Dinner - Rice with Chicken and Vege
Sometimes gila will have Mcd for supper. Once a month.

I cycle to class. So currently that's my only work out.
Usually sleeps around 1am and wakes up at 8.30 am for class. Do this contributes to my weight too? - Not really. Unless you feel you are not getting enough sleep.
1 more thing, i found out that i sweat a lot easily. Especially when eating spicy food. Sometimes I cycle to class. Waiting for it to be empty. Stand outside for 5 minutes only, the back of my shirt like soaked with water already. -.- sign of overweight? Definitely not. I know some skinny people who sweat a lot as well. As far as I know, there is no correlation between how easily you sweat and your BMI

How to improve my diet guys? Help! Is it okay if i change my lunch to bread only? Start working out? Increase your meat intake while reducing your rice + gravy intake?

I don't feel that I am not getting enough sleep. So that's out of the question.
If I just wanna slim down (not getting 6 pack definitely), cycling and basketball everyday is sufficient? Because in my uni, cycling is my main transport. lol
About taking more meat and reducing rice + gravy, I'll be google-ing on that. Didn't know that meat intake wil help in weight lose. 
Snacks in between
Breakfast and lunch - biscuit (again), sometimes maggi
Lunch and dinner - none
