School and Stress

Weighing your food on a scale in grams and logging just takes about 5 minutes each day once you're accustomed to the routine and you've added a few commonly cooked recipes. but even if I cook something from scratch it doesn't take much longer.

You don't need to work out for weight loss as it happens about 90% in the kitchen (others say 80-95%). Sport is for being healthy and fit. But honestly, you don't need much time for sport. Learn to run and just do a run at lunch time on campus, after getting up or going to bed. You could also do bodyweight exercises at the same times. Or are you really, and I mean really working from getting up to going to bed?
