When I started this diet, I gained a bit of weight. I’m almost the same size, but I weigh 67 kg (148 lbs).
Your diet seems about right. You seem to consume enough fats. Since you always feel full after a meal, it shouldn’t be too much of a concern. Maybe you are lipase deficient which means that you can’t process fats very well (floating bowels is a typical symptom). If so, it might be a good idea to add some enzymes.
