well, I just got some ketone sticks off e bay and did a random test, I got a slight amount and then later, a negative. I'm just aiming to reduce carb intake to less than 20 grams a day, hoping that it does something. I had a gastric band, and lost 6 stone, and then it stopped working so I had it removed, and had a bypass. I have lost 2 stone with the bypass, but the weight loss has ground to a halt. The surgeon said that following revision surgery, the weight loss is less predictable. I have 2 more stones to loose, so I thought I would give low carbs a go. The bypass means that I cant eat bulk because my stomach is small. Also, too much sugar and it makes me feel very nauseous. I am almost low carbing any way so thought I may as well go for it and keep it under 20 grams. Why do you have carbs once a week ? Sounds very yummy, does it slow down the weight loss ?
