Time to find out what the 5:2 "fasting diet" is all about....

By fitasamonkey, Aug 30 2013 01:19PM

Having had a week off from work (and eating sensibly!) I decided it was time to trial the 5:2 fasting diet.... This week that involved a test run Wednesday to see if I could cope with only 500 calories in a day!

So the concept is that you choose 2 non-consecutive days to "fast" which means only eating 500 calories and for the rest of the week you eat normally (about 1500-2000 calories depending on the person).

Well.... I managed and although I did feel a bit hungry at times what I struggled with was the lack of energy, for 500 calories its hard to get many carbohydrates in....

Here's a summary of my day:

6am up and out the house (after a glass of water)

Personal training sessions 6.30 - 9am

Cooking gluten and lactose free foods for a friend 9.30-1.30pm

*12pm bowl of broccoli and cauliflower soup with a rice cake (100 calories)

Home for a few hours - shower/emails/prepare my main meal

*3.30pm Tuna steak (150 calories) steamed broccoli, sweet corn, cherry tomatoes and garlic mushrooms made using light olive oil in the wok (129 calories)

*4pm handful of strawberries (21 calories)

Personal training 5.15-6.15pm

*Apple (45 calories)

Circuits class 6.30-7.30 followed by personal training 8-9pm

*10pm rice cake with a thin spread of peanut butter and a glass of squash (55 calories)


Probably drank about 3 litres of water and 1 cup of nettle tea :-)

So I had fasted from 8pm Tuesday until 12pm Wednesday - 16 hours and then managed to eat 500 calories spread out over the rest of the day. I have to say when I woke up on Thursday I had to eat a banana and an apple on route to my first client for a 6.45am personal training session!

Apparently it gets easier so next week I intend to attempt to fast on the Monday and Wednesday and complete a full 5:2 week.... wish me luck!!

Please do let me know if you've tried this! Get in touch via email [email protected] or facebook or twitter (make sure it's medically suitable for you to do it if you want to try it - if you have trouble maintaining a level blood sugar during the day then I would say it's not for you)
