Doesn't make sense to me at all. Yes, it is really good thing to be really busy with something in life. But are you really that busy that you dont have time to enjoy a good healthy meal? What abut sex ? What about girlfriend or wife ? Hey and is sleeping is also waste of time ?

Well, there are always pathological cases like this particular man in question but I dont think anyone else should even try this sort of stuff.

Secondly, our body has evolved not just to digest nutrients but also normal food which may contain many other essential things science is not yet fully aware of. So this sort of artificial diet is risky and it might cut your life by few years. Is it worth it ?

You don't need sex to stay alive. As for sleeping there are attempts to hack that too. [0] Not everyone thinks that spending 30 minutes or more to prepare a meal is worth their time so they time to minimize it: from take-outs to microwave food. As many already said in this thread, this would be a step-up for many.

You can't blame him for trying. That's more than most of us are doing.

There are also many people who would try this, including me. We don't know what we don't know and this might be a way to find out. Is cutting your life by a few years worth prolonging the lifes of billions of others?

You are missing my point. My problem with this approach is that he thinks that food is only for "staying alive". Like many others here, even I love my work and I too constantly figure out ways to make myself lot more productive.

But giving up a regular meal for a formula sounds like over optimization for me.

I got fat, unattractive, and out of shape by overeating. Food is a visceral experience that it's not healthy for me to be too attached to, and I'm more than willing to sacrifice it in return for more of all the others. I'm already alternating between small meals and protein shakes (plus fiber) to dull my carb cravings and lose weight.

Sleeping is a waste of time.
