Dieting during school or work

What are someways you can workout at school and eat more healthy without the time to fix healthy snacks?

I buy pistachios in bulk and then portion them out into snack bags of 49 nuts per bag (shells on). I also portion out celery, carrots, mini sweet peppers, cucumbers on the weekend so it's easy to throw those in my briefcase. I workout at work everyday. I do three laps of the stairs every morning first thing (I work in a 6 story school) to get my day started, then I workout at the end of the school day in the fitness room. I never take the elevator. I take the parking space that is farthest away from the door. I do kegels all day long.

They say " if you want to get something done ask a busy person" if you are organised you can make a few minutes to make a healthy lunch, most supermarkets do packs of prepared veg like carrot sticks etc, my husband is a truck driver and starts work at 3am so leaves home at 2 am, he or I sort out a bag before going to bed with a roll, a pack of fruit, salad or cherry tomatoes, then when he gets up he heats some soup in the microwave and pours it into a wide necked flask, he also takes a flask of hot water so he can make hot drinks avoiding the starbucks temptation. If he has worked a long day, 14or15hrs he has skin free cooked chicken from a pack when he gets home with veg and sometimes a baked jacket potato. As it can be ready in 15 mins leaving him enough time to get some sleep, this is working for him, maybe something there might be of help

Im not sure what your school will allow but I have a desk job where I sit 12 hours a day. I now sit on a yoga/exercise ball all day. It improves your posture and works your abs. I can also do crunches while sitting on it periodically throughout the day or stand a few other exercises that are easy to do for a minute or two at a desk. If you're in school you can do leg lifts sitting at your desk and power walk to your classes, theres not a whole lot you can do in class that won't be deemed distracting.

Keep fruits and veggies handy. Fresh is best but I dont know how long you're in school and if keeping fresh food is an option. If not theres dried fruit, get the no sugar added stuff or fruit cups, all natural or in water also no sugar.

You could walk / run up and down stairs if you have any at school. Any other way to get your heart rate up will burn more calories. Starjumps etc. Take note of portions sizes especially meat (only need size of your palm) and pasta/rice. All the best.
