Yes Scott, I'm going to look into that. I know ruminant meat is what most recommend. The first 3 weeks I was eating grilled pork bellies because they were the cheapest fattiest meat I could find, and I dropped 6kgs (some was probably water weight). I was also eating a lot of eggs and butter. I then went onto 'Rump tails' not sure what it's called in other countries. The meat is cheap and has a nice layer of fat on it but I think it's too lean inside. I'm not exercising because it's so cold and wet outside (mid winter here) but I think I need to do as you did. Start exercising, find a fattier cut and reintroduce eggs (because they pair so well with butter) am considering asking my butcher to make up a few kgs of 60/30/10 Beef/fat/liver mince so I can have something quick to nuke with the eggs. I have found a place that sells pure a grade beef tallow in 5kg tubs so that's next. As you say it is an experiment and thanks for the advice. I have already started to see other health benefits so this is no longer a diet for me. This is tuning and tweaking the way I'm eating in future. Cheers
