I love the topic of Ketosis as a calorie restriction memetic, so I must weigh in.
I was in ketosis for about 6 months. I recorded my blood work monthly and saw a DRAMATIC improvement in my triglycerides and a modest improvement in HDL & LDL despite the enormous ammounts of saturated fats.
But I didn't feel great. Excercise is difficult while in Ketosis, plus i wasn't super excited about the food after a while.
Anyways, if you look at metabolic pathways, fat intake doesnt turn any / many of the nutrient sensing pathways which deactivate CR mechanisms. This makes sense because your body uses its own fat while starving. So this seems viable, but I don't think it is proven out in any animal studies though I would be interested to know of any.
This is also relavent to bodybuilding while in CR, because it is one of the few mechanisms that might allow the body to stay calorie neutral while having longevity pathways turned on. That said, ketogenic diets don't create anabolic signalling that is required for muscle growth, so BCAA's are probably required. (Good news is that BCAA's act down stream of the point where major longevity pathways (FOXO) are activated.
Also,
I'll just leave this link here

I tried a ketogenic diet of basically protein powder, oil, and supplements earlier this year and really came to hate it. After the "induction," I didn't notice any increase in energy that couldn't be attributed to placebo and I theorize the energy for the folks who do swear by it comes from an increase in IGF-1 by all the animal protein the diet emphasizes, which definitely isn't a good thing long-term.
Its difficult to stay in ketosis with significant protien intake. Needs to be ~50g. Don't know how much protien you are taking.
Also Also,
Its not clear that you actually need to be in Ketosis to have pro-longevity pathways turned on. Hell, its not even clear (except in metabolic pathway charts) that ketosis turns on pro-longevity pathways.
