So, things going quite well this month.
Weight down nearly 5kg in a month. 7cm off the waist. Still over 27% body fat though (estimated, US Navy method) so no room for complacency.
Started 5:2 fasting properly in the past fortnight. Prior to that, just "eating a bit less", moderating alcohol intake, and gave up liquid milk completely; Also trying to cut out snacking, sweets, biscuits and the like (though not completely).
Feeling optimistic going into February - not often I can say that! Will continue with the 5:2 and the milk ban; Will also start a regular exercise regime (Commando 7) now that I'm not quite as abdominally obese as I was.
