Fat doesn't have any direct effect on blood sugar, just indirect effects such as delayed absorption of carbs and possibly increased insulin resistance for carbs.
Your overall macronutrient ratio (by calorie value) is around <10% from carb, <40% from protein, > 50% from fat. If you can maintain this diet, you should be fine. Some might say the protein level is high and have concerns about that. As long as you don't have kidney problems, my personal opinion would be not to worry about that.
