Hi Jam,
I would suggest to consume high protein foods. Go for chicken with rice, its delicious and healthy. Or lentils stew with beef.
I would skip all the fruit juices (even if its freshly squeezed) because it will just drive your blood pressure up and down from all the sugar which is in it. Go for water with freshly squeezed lemon, make a huge bottle and put it in a fridge to cool down. It'll give you some energy.
Evenings, you can eat all sorts of salads, like mozarella with tomatoes (olive oil and vinegar glaze on top) or oven bakes cheese sandwich with cucumbers etc..
Chicken:
- 3-5 chicken breast
- buy those instant rice package (4 in each) and just boil one for each menu
- spice it up with salt/pepper and some roast chicken spices
Beef:
- you can get lentils in a can (with water only) or can buy raw lentils and soak them in water overnight which is healthier but I suppose you don't have time for such
- 1/2 kg beef (for stew cut up already)
- grill the beef for about 2 minutes each side in a pan, add salt and pepper (pressed garlic if you like it) then mix it with lentils and stir it for another 5 minutes and voila you're ready
Lemonade (no sugar)
- cold water
- squeeze 1-2 lemon and mix it
After a long session if you have trouble to fall asleep just make Camilla tea (about 5 min work) and you will insta fall asleep.
- boil 3dl water
- soak tea bag for 2 min
- ready to drink (no sugar)
for snacks you can get grapefruits, full of with C-vitamin and it'll wake you up a bit.
Hope this helps
Ingrid
