Four suggestions: 1. I agree that your carb count might need to be lower, like under 40 g per day, as in "induction" phases of the low-carb diet plans. This amount would be temporary until weight loss is achieved, then it could go up to a "maintenance" amount, which may be the amount you're doing now 2. I think the satiety factor with the tuna/olive oil vs. red meat/saturated fat might also be the protein selection. Red meat has more purines, which some people need to get sufficient energy. I am a fast-oxidizer metabolic type and I do best with high-purine meats (dark, organ) and high-purine veggies too, but the meat is most important. I could eat a low-purine light or white meat with lots of fat and be hungry in an hour. 3. Some people go into a weight loss stall because they are eating an allergic food. I don't know how this mechanism works, but I've heard of it and also experienced it. I don't lose weight while drinking black coffee because I have some kind of intolerance to the coffee. So I just won't lose. As soon as I quit the coffee I start dropping. I've heard of this phenomenon with many other people, with varied foods (like dairy, eggs, and other commonly allergenic foods). 4. Some people do VERY well adding a Carnitine Tartrate supplement. Studies have shown good results with how it increases weight loss - Robert Crayon who wrote the "Carnitine Miracle" and also is pro-paleo has a lot to say on the benefits of supplemental Carnitine- has to be Tartrate form though, and is expensive. I've seen people get great results on it. good luck Laura
