The end of week 2 of the Keto diet (otherwise known as the 'Let's lose weight by getting scurvy' diet) and I have lost a further 2.6 kilos and am now at 123.9 kilos. I started 2 weeks ago at 130.3 kilos, ended up at 126.5 kilos after week 1 and 123.9 kilos today after 2 weeks. That is a total loss so far of 6.4 kilos (just under a stone) in 2 weeks, or 5% of my starting bodyweight.
I have been very disciplined on it, with a minimum of 1000 calorie deficit per day (often more as I end up not eating my allocated calories even then), not even remotely hungry (as body is burning fat for energy anyway so isn't starving) and whilst week 1 would have seen a lot of water weight lost week 2 would be quite a bit of fat.
So I'm pleased thus far. Regrets are lack of exercise opportunities - I've been unable to get more than about 6k steps in a day and when I did keto 1st time round I was doing 20k steps a day and once I get down to around 110 kilos (would take a couple more months I reckon) the aim is to start running (my apartment is in a park on the Thames plus Bushy Park and Richmond Park are both less than 1 mile away).
As stated before this diet is something I will be on until June, at that time I will move onto something more sustainable for the long term. I do find keto to be a pretty expensive diet if I am honest - plenty of meat for protein and even the veg that are compliant for the diet costs more than normal veg (Tenderstem Broccoli is ideal).
Booze is possible (Gin and Slim, Prosecco, Champers etc) however I've not touched a drop since New Year's Eve and don't miss it (wife doesn't drink and we never have wine with meals etc). The other thing about keto is it is a very individual diet - I end up cooking just for myself and eating alone as my wife and son are (very reasonably) not on this diet. So it is a bit of a faff making multiple meals but it is what it is.
