It will not work aswell without the 1/3 superfree, you are supposed to have it, the idea is it stops you overeating other stuff. That's why both meat and carbs are free on EE. One of them has to be limited on red and green because you don't have to fill up with fruit and veggies, so you could easily overeat.
Whilst the 1/3 superfree isn't compulsory, it helps to keep you full for longer and gives your body the nutrients it needs. Regardless of whether you're having the 1/3 superfree, we should still be eating 5 portions of fruit and veg a day anyway.
I have a hard time eating all my veg. But I would say I eat about 5 pieces of fruit a day and squeeze my favorite veggies in where I can. In an ideal world, I think 1/3 would be the way forward. Not always possible for me with how much I work and a needy 3 year old. I keep telling myself that I'll make time to portion veg out for the day (peel and cut carrot batons etc) but it never seems to happen. Tomorrow is Saturday so I'm going to do my best to get that done...although I still have to go to work...in a restaurant...ugh
I don't always have time either but I buy bags of frozen veg from Tesco. You just throw them in a pan of boiling water or the microwave for 3 mins or I add them to pasta n sauce or savoury rice while it's cooking. I try and have fresh veg whenever I can but this is a great way of saving time and still eating healthily when you are busy. (Just be careful when buying mixed bags as peas and sweetcorn are free, not superfree so don't count towards your 1/3)
