minimal carbs, nailit, no pasta, bread, cookies, cake, pots, rice, and sugar.....minimise sugar intake (read labels - serious on that, even prepared soups. No processed OJ by the way!
what I am permitted is (i) porridge - low glycaemic sugar release and fibre against cholestrol - though I am relatively low to begin with - 4.6 (total LDLs and HDLs).
(ii) alcohol - it's allowed other than beer, cider, sweet white wines sweet drinks, no soda, false orange juice etc, so my diet includes Rioja, Sauv Blancs and Scotch......
(iii) as much meat/cheese etc and I am allowed - fruit as well (obviously taking account of the sweeter ones) - surprisingly beetroot ain't that bad. That said, it's mainly apples, like Granny Smiths, the occasional apple. Avoid sweetcorn and the like.....
For spuds etc, I've subbed into braised chicory, which I love, celeriac and swede purées - mix with shallots, chillis etc. I've only missed the occasional pasta, seriously. Then as many veg as you like, lots of fish, and even meat, - re-discovered Guinea Fowl recently.....
Result, 32 pounds off in a quarter.
Advice - consult with a doc - with a gall bladder, you shouldn't lose more than a kilo a week or you risk losing it. Without, best to be under doc's monitoring - I need to lose another 2 pounds and I am into see the doc to check the essentials (blood test) and then I'll be allowed some measured carb a week, increasing to find my natural level and he reckons I'll lose another 1.5 to 2 stone in this phase and this would bring me close to my rugby playing weight. Yes, I hit 19-4 and am now about to plunge under 17. Playing weight was 14-10, loose head prop.
Hope this helps.
