hey... it's me from the english lit powerpoint
i'm sorry you're feeling like this, but please please do not avoid full meals - especially when you're in the middle of your exams. your brain needs all the nutrients it needs (including starch and carbohydrates). not eating full meals and only eating snacks will result in you and your brain being malnourished, and believe me it's not something you need right now if you're trying to get good grades. if anything, increase your meal sizes and after your exams are over, you can decrease them. but only a little bit as only eating snacks and avoiding proper meals actually slows down your metabolism (which is the rate that your body digests food). having a fast metabolism is key to weight loss, so your body needs enough food for this. also if your body is lacking food it'll actually preserve your fat on your body as it thinks that there is a shortage of food, so it doesn't want you to suffer. this is why eating full and substantial meals are important
with exercise, if you had a treadmill the one thing that i would recommend is the 12-3-30 workout (walking on 12 incline, for 3 miles per hour (4.8 km) for 30 minutes). i used to go on the treadmill nearly every day but this workout is wayy harder than it seems, and i'm a generally fit person. i was literally sweating after that and i never sweat haha, so if you (or anyone else reading this) tries this and feels bad for not being able to complete it, don't worry. literally even i couldn't do the full 30 minutes (i got up to 26 i didn't even have the stamina to do 4 more). so anyways i recommend this because it's a quick workout and you can listen to a revision podcast if you want. but bear in mind it takes a month to see some results, and you need to do this consistently (every 1/2 days) and eat healthily (with full meals)
also girl don't even worry about bloating. everybodyyy gets it. even if you see people walking around the street with flat stomachs, 99.9999% of the time they're bloated and they're sucking it in. also remember, bloating does not equal fat! i see this misconception everywhere and i really need to put this right. bloating is mostly gas - and it's completely normal. but if you're really that bothered with it then taking care of your gut might help. like having probiotics and reducing your salt intake a lot could reduce bloating but as i said before don't worry about it because everybody (man, woman or non binary) gets it!
also my last point is - drink 2 liters of water a day. seriously. it helps so much. the only bad thing about that is that i've noticed that i get more bloated that day that i drink it, but they day afterwards i feel like my bloating has reduced overall so yeah
don't worry about anything right now while you're doing your exams, you really don't need this added stress
i just realised i wrote a whole ass essay but i really hope this helped!!
