I need lose a LOT of weight - I weighed in at 99.4 kgs this am - I can't bear to convert to stones....I am trying my first 5:2 fasting day but I am seriously struggling and now wondering if maybe I stuck to 800 cals a day for the first month would that be easier? So far today I have eaten 246 cals so have 254 left for tea only. It doesn't help that I have just recently been put on citalopram and am sat at my desk with sweet FA to do thinking all I want to do is have a snooze!
