I am in a confusing situation now as I told my parents that I am going to go low carb at the weekend and when my parents went shopping for food they came back with mostly carb based foods like pizzas, pasta, potatoes, rice , pastries, bread, family cereals. They also especially bought me some low fat fruit yoghurts which they said would be alright for me and when I checked the sugar content they contained 20 grams per pot and they were from Morrisons. After I told them I wouldn't be able to eat them we had a argument about what my temporary doctor said to me about low fat dieting, then I told them about weight loss with doing a low carb diet and showed them this site and they are still totally against and I don't know what to do now as I have my blood tests tomorrow and will have to eat what my parents have in until I go back to university in September.
