You are university student. I think you should know that the important of eating 3 meal in a day and skipping meal doesn't have any health benefit to you. Even many teenagers know these can cause health consequences
If you really want to get weight loss, you shouldn't skip any meal. more meal less portion would be benefit. Daily physical activity is very important: For aerobic exercise(any exercise the contain rhythmic movement for long period of time (more than 15 - 20 min) such as jogging, walking, swimming, cycling, and dancing. In ACSM and CSEP guideline you should do it most days of the week (I recommend 5 days/ week). For the intensity should be around 50% - 75% of your Heart rate reserve:
there is simple calculation
target heart = (50% - 75%) x (resting heart rate - max heart rate) + resting heart rate
Resting heart rate is the heart rate when you just woke up or the heart rate that you sitting or lying doing nothing for long time.
max heart rate = 220 - age
for example my age is 22 and my resting heart is 78
then my target heart rate should be around
= (50% - 75%) x (198 - 78) + 78
= 168 - 138
when you are doing aerobic exercise check every 2 min to see is your heart is in that range
PS: remember to do warm up exercise around (5 - 10 min) such as light walking or dynamic stretch. And cool down also important such as light walking or static stretch.
