Dropping nuts broke my plateau recently. At least, it got me down from 177 to the low 170's. Now I'm almost pure primal. Fats, greens, roots, and fish, liver etc. Have you tried adding coconut milk and oil to your fats when cooking? A can of coconut milk makes a great 765 calorie breakfast to get your system cooking. How many calories do you eat in a day? You might not be eating enough. I easily break 3000 calories per day, sometimes I even hit 4000, and I'm still losing weight.
Steak, eggs, potatoes - fruits, nuts, berries and forage. Coconut milk and potent herbs and spices. Tea instead of coffee now and teeny amounts of kelp daily. Let's see how this does! Not really had dairy much, and gut seems better for it.
