You won't get fat. It mainly depends on the amount of exercise you do the next day, whether it is moderate or normal. Dieting is not recommended during the day. Eat what you should, mainly at night. If the landlord doesn't go to bed until about 12 at night, it is suggested to add a snack (not high in calories) in the middle before going to bed after meals. I eat less and less at night, but I can't help eating. Although there was a saying in ancient times that "no food in the afternoon", the ancients basically went to bed at 9 o'clock in the evening. We modern people not only sleep late, but also have a heavy workload, so studying like ordinary students is medium labor. I hope the landlord can adopt it.
