I've sat down, and plugged more data into my spreadsheet. If (and that's a big if) my body composition monitors are to be believed, I started the year with 22kg total fat, of that 13.3kg was sub cutaneous, and 8.8kg was visceral. After one month, total fat is down to 19.5kg, just over a 2kg loss and that's split into a 1.4kg of sub cutaneous fat loss, and 1.2kg of visceral fat loss, along with a 500g loss of muscle.
The body composition monitor just gives me percentage of type of fat and muscle, so I'm having to make quite a few assumptions with my maths.
Going to start doing some resistance work, ie push ups and kettle bell stuff, and monitor it again for the next month.
