Pros/Cons of 16:8 only on non-workout days

**Background:** I've been practicing IF for a while, **mainly** because it is an easy way for me to manage my daily calories. With IF I can easily eat at at a deficit or maintenance if I want, and it doesn't take much extra effort to be in a surplus if I'm trying to gain muscle. With "normal" eating throughout the day I almost *always* eat at a surplus unless tracking calories, which is mentally draining. But since I've been doing IF, I have enjoyed the extra free time in the morning, the fact that I'm not addicted to eating, the mental clarity, and the possibly health benefits such as reduced blood pressure and resting HR, and the prevention of developing diabetes. ​ Recently my strength training sessions and conditioning have become a bit harder, and I'm wondering if I will benefit from consuming carbs and whey protein before my training, and whey protein after. This is mainly because when doing heavy lifting and conditioning while fasted, I'm not able to perform at 100%. My pre-workout would be a large banana and whey protein shake mixed with water. Post workout would be whey protein mixed with water. Since I only train about 2-3 x each week, I would do 16:8 IF for 4-5 days, and would break my fast on the other 2-3 days just for the pre and post workout meals. ​ **Question(s):** 1. By *not* doing 16:8 for 3 days out of the week, am I reversing or not seeing the health benefits that I mentioned above (lowered colesterol and HR, prevention of diabetes)? Do these benefits only come from 16:8 every single day? 2. By not fasting for 3 out of 7 days, will I be screwing with my hunger and cravings? I have a busy schedule and love that I can go extended periods of time without food. I'm afraid that if I stop my 16:8 schedule that my body will start to be hungry and more "dependent" on food. 3. Or, am I just better off to continue what I'm doing? 16:8 - training first thing in the morning and eating from 11-7? Will I really see significant improvements in performance and muscle/strength gain by consuming a pre and post workout protein shake with carbs? 4. Has anybody stuck with a strict 16:8 schedule and been happy with muscle and strength gains?
