High protein continually isn't necessary nor optimal. I cut my protein drastically after I reached my ideal weight. By the sound of it you're high protein/high fat but probably pretty short on plant foods which contain hundreds of potential antioxidants, caretenoids, polyphenols and other phytonutrients that protect you from and slow down the aging process.
The science on different protective plant nutrients that are being discovered by the day is so vast. I think that kind of stuff is extremely underrated/overlooked on here. I'm not suggesting you start living off goji berries and kale smoothies but sweet potatoes, berries,fruits, avocado's and other vegetables are amazing foods.
You probably have an excessive methionine content which wouldn't be doing you any favors.
