Basically, yes. That is The P:E Diet in a nutshell. (Plus for "keto" folks increasing healthy, high fiber whole food carbs).
My journal is relatively new, so you will find there summarized what I changed in the past 2+ years in the first few posts. Many links to podcasts, articles, food lists at DietDoctor how to tweak Low Carb to Higher Protein and Satiety.


Consider for breakfast 2 eggs (for the nutrients like choline) plus 6 - 8 oz.egg whites, add a lean meat like Canadian bacon, turkey bacon, canned fish, leftover chicken, maybe include some vegetables. Eat higher protein and lower fat than you do now, increase the protein % of your diet slowly. There are more food lists in the first few posts of my journal. I usually eat two meals a day, plus a high protein, low fat dairy snack, e.g. protein powder in Fage 0% yogurt. So first meal is not "breakfast" but more a brunch so I have stirfries, or salad both with 6-8 oz of a lean protein.
