I started to diet seriously after watching Michael Moseley's programme 'Lose a stone in 21 days'. Well it took 7 weeks for me to lose a stone but to be fair I haven't done any exercise or it might have been quicker. Since 13th August I've lost 1 stone and 3 pounds by cutting out carbs/sugar and trying to stay below 800 calories.
The idea is that carbs turn to sugar which the body uses for energy, so if your body has no sugar it starts to eat your fat, this is ketosis. No supplements needed.
I allow myself 30 gms of carbs each day. To make the diet less of a diet for me I can have a can of Kronenbourg 1664 at about 16 gms carbs and a small, thick slice of Warburton wholemeal about 10gms. Chocolate eaters can have a Flake at 20gms of carbs, dark chocolate has less carbs. As long as you count the calories you can have these treats. For breakfast I sometimes have a sausage, egg, bacon, mushrooms and tomatoes and that's less than 300 calories and a few carbs in the sausage. You can't really eat fruit as it's high in sugar but meat, poultry, veg and salads are pretty much carb free.
It's working for me and it's the first diet where I haven't been hungry or craved for something. In fact it's becoming more a way of life than a diet now after 10 weeks.
Some weeks I haven't lost any weight at all but haven't gained any either, even though occasionally I've jumped off the wagon and had ice cream or garlic bread etc. I'm going to lose another stone and then stop counting calories and just keep an eye on the scales. I've also lost 6cms, just over 2 inches, round the middle.
