Good Morning Sarah,
But so far... We truly have been feeling like a million bucks.

Well, OK, I will not contradict your own experience. I definitely experience reduced activity on fasted days. (Definitely not a day to do a 25 mile bike ride, for example.)
But, who's Sarah?

So let's be a little frank, the human body is terrible at telling you something unlike it's highly broken. So unless you are getting frequently dexa scan, metabolic panels, etc... You won't know many things like, are you losing muscle, are you developing vitamin or mineral deficiencies, etc.. another example, how many people have you known who didn't know they had cancer until it was too late?
I enjoy Keto. For some it's extremely good at blunting hunger... Some a little too much. While I do clean keto, it's very easy for me to go extended periods without food. So that is a huge positive.
But, there are a lot of negatives to Keto and that is even more exaggerated with IF. The two biggest is reduced ability to sustain muscle (carbs are anti-catabolic and protein sparring) and carbs significantly help with gym performance. Fasting is catabolic... That is just a fact. Combining fasting, especially long periods, and keto will increase the likelihood of muscle loss. Muscle loss will lead to a slower metabolic rate. Now, i know the argument that Fung and people like Thomas Delauer make... Fasting increases HGH. Well yea, it's true. But hgh doesn't increase muscle mass, even if a person is injected with super physiological doses. When injected with HGH, you would see an increase in lbm from increases in total body water and improved connective tissue. HGH does serve a second function.. and that is mobilizing fuel substrates. The transient increse in HGH is to metabolize fatty acids.
I think it's awesome that you are enjoying this, but understand if it's going to support long term goals. I run keto for periods of cutting and then add carbs in hopes of preserving or building muscle. If your goal is lean and defined, keto and IF will likely work against that. It's something to consider.

Unfornately, still so many people on MPL cling to the old ideas of fat is bad and fasting is going to cause you over eat. Don't mind them, you are doing great.

I am un the same course, for now I only do intermittent fasting by eating one meal a day, but I want to try longer fast in the future too.

I expect under eating problems like hair /nails/ teeth to take longer than 4 weeks to manifest.
Whether you are doing keto or not_ eat , on average, the amount of calories you are meant to and don't fast for excessive time periods, if you must do it at all.

You obviously aren’t going to change what you are doing until a problem is visible in some way.
So, all I will say is please, both of you talk to your doctor, explain your weight loss plan, and ask him to monitor your health and run bloodwork checks monthly. This way any problems (and there will be) can be caught before remedial steps have to be taken.
Anything that is so low cal (relatively speaking), and includes regular multi day fasting should be done with medical guidance.
If you won’t work with your doctor on this, ask yourself why.
I have spoken to my Doctor in the past and another Doctor more recently about Low Carbing.... And both of them were for anything that works to reduce my weight.

Nobody here was against Low carbing - if that is a WOE that suits you
and of course if you are very overweight anything that reduces that is a good thing
Extrapolating from that to fasting for 48 to 60 hours is the issue.
But you have made up your mind - so be it.

Out of curiosity, what is it that seems exciting about a 60 hour fast? Are you reading stuff that suggests it will be some mindblowing experience or is it because it seems like a feat or what? I'm just curious. (I don't think fasting for essentially two full days will hurt you, although I would be really careful and read about how you should refeed, since I think that can be the most risky part. It just seems pointless and unpleasant to me.)
