Hi Toddy,
I started off by cutting out the “big whites”, bread, pasta, pizza, sugar etc. Then I started to use an app on my mobile phone called myfatsecret. It allows me to enter each meal or ingredient and see what the number of carbs, protein and fat works out at and I could tweak the ingredients to try to stay on target.
Its easier to stay under 20g of carbs if you are a meat eater, a bit more difficult for vegetarians, but I found by cutting out the carbs I wasn’t craving food at regular intervals a day, so that gave me the option of reducing how frequently I eat so I can save up my cars/cals to have a varied diet when I do eat.
I have been eating this way since last October. Have lost over 6 stone, without feeling deprived once the carb monster was kept in its box. – You may hear people talking about eating 16:8, or 20:4 which means that they are doing mini fasts for 16 or 20 hours and eating in an 8 or 4 hour window. Thats where I am at now, I tend to eat 20:4.
