Controlling my carbs worked well for me. I tried a CKD but was to lethargic on it and was experiencing headaches. Keeping my protein high, fats high quality (i.e. almonds, olive oil, flax seeds), and carbs low glycemic allowed me to lose 30lbs in 4 months. Seems to be a lot of research that controlling your insulin, by the foods you eat, is what makes a number of people successful.
