I find low carb works for me. I did Atkins many years ago and I lost over 21kgs, felt great as well. Now I don't tend to go full on low carb, but I just find being very aware of the high carb foods does help. I have a tendency if I am eating bread, pasta or potatoes that other foods drop off, like leafy greens. So I will try to have meat and salad, as opposed to a ham and cheese sandwich.
