If you having fat mixed with the protein then you should be ok, you are aiming for a 50:50 ratio of fat to protein and if you go over, do so on the fat side. 1 gram per lb bodyweight should be adequate but no more than 1.2 per lb bodyweight. It would take a pretty decent amount of protein with your meal through food to spike your insulin lvls, the added fat will blunt any insulin spike but not mask it totally. Here is an average breakdown of my day so you have a reference:5am wake up10 g whey isolate2 cups coffee1 tbsp coconut oil2 tbsp whipping cream (not whipped cream)10 am25 g almondscoffee with 2 tbsp whipping cream12 pm4 whole eggs3 tsp unsalted butter30 grams cheese2 tbsp flax seed2 cups baby spinachall blended into an omelet3 pm1 can low sodium tuna3 tsp unsalted butter2 tbsp low sodium mustard5 pmsteakveggiesIn 1 mth on cns I dropped about 5 lbs fat but I saw an increase in strength, I absolutely avoided cutting calories to establish that the fat loss was not due to caloric cutting. If you really want to get the most out of the diet for muscle retention or even slight building then do a good hard workout just before your carb nite starts (I work out around 5-6 pm so I left the carbs to post workout). Now I am pretty active so keep that in mind for food but if you are lacking energy then you need more fat to supply that need.
