Guest post: 5-2 diet diary

This is another guest post from Roger

Last month was the x:7-x diet, where x is supposed to be 2.

I have done this for some time in the past and found that it suits me and has the desired gentle effect.


There is some hocus-pocus surrounding this diet that involves ketosis, but it may be simpler to observe that if you grossly undereat for 2 days, you may well not catch up in the other 5 – I’m fairly sure this is true in my case. So often at the end of an under-eat day, one says “Ha! Tomorrow is bacon sandwiches and beer”, but it doesn’t actually happen. So I think it works by driving down aggregate calorie intake. Remember, as a result of the SSSS diet (see last month) our intake is already reduced by 10% by virtue of smaller crockery.

I have devised an objective scoring scheme for diets with which you will be familiar, so we can now judge the 5:2 diet. During this month I came to enjoy the cleansing effect of no-eat days – you can put up with anything for a day.

If you believe the [upgraded] weighing machine in my bathroom (which nobody in their right mind would) I lost about 0lb in 4 weeks (and gained 0). this is faintly disappointing as I would expect about 0.5lb/week, but it’s OK as a result. Ergo, I score it at 8 for tolerability and 2 for effectiveness.

The scores to date:

Month Regime T E M, α=0.5 M, α=1 M, α=1.5
January Low carb 3 8 7 11 15
February Slow carb 1 0 1 1 1
March SSSS 8 5 10.5 13 16.5
April 5-2 8 2 9 10 11
May Astronaut 11

Next month we will subsist on astronaut food, which it is difficult to look forward to. My diet1 promises to be much better.

More anon.
