Earlier quoted context omitted.

In India, there are monks who live without any food (and water as well) for more than a month or so. Initially, I did not believe but then I confirmed from many people and it was true. They basically do meditation during that period and gain their energy from nature.

Watch this documentary and see what people say. Hey HN folks, Sometimes science does not explain everything.

You must either be quite short or female. The average healthy male would be losing weight very quickly at such a large deficit.

I am 5’8, and if you are familiar with studies of someone similar doing the same thing, I would love to see them. :)

I imagine you are still losing weight? Otherwise eating like 1000kcal below maintenance would be defying thermodynamics.

That’s great and all, but you cannot build muscle unless you’re on a caloric surplus. Good bye resistance weight training with the goal of having more muscle. The irony is that having more muscle would also increase the amount of calories you need to maintain (not get bigger/fatter, not get smaller). What I’m trying to say is that a “deficit” completely depends on what your current lean body mass is. If I want to go…

That's a good point. One of the dangerous of calorie restriction or any type of weight loss diet is, it seems, losing muscle mass instead of fat mass.

A reasonably developed muscle mass has shown many health benefits in age related diseases, such as preventing osteoporosis, diabetes and high blood pressure.

These people still exhale CO2 and water vapor. Unless you believe that matter spontaneously appears inside their bodies they have to lose weight.

So far in 2018 I have had one ~1300-1500 calorie meal per day for all except maybe ten days (where I have gone out for drinks or have extra food late in the evening with friends). The strangest thing so far is how much my body has adapted to this - I skip breakfast and lunch every day, yet don't feel particularly restricted (save socially), hungry, or weak. I am just one person, but I now intuitively feel that whatev…

I have recently started doing something similar. One longer-term concern for me is non-macro nutrients (i.e vitamins/minerals). Have you had any thoughts about doing supplements? I'm also somewhat worried about the bioavailability of supplements...

Couldn't you just eat more nutrient dense (but low calorie) foods at your one meal? Veggies are a prime example.

This is difficult to follow in daily life although not impossible. Given that food is becoming less nutritious as per [1] taking less food will mean less nutrition which can affect general well-being. Figuring out foods high in nutrients, low in calories will require a lot of discipline. [1] https://www.nature.com/articles/nature13179

> Figuring out foods high in nutrients, low in calories will require a lot of discipline.

Will it, really?

1. Skip the snack aisle

2. Visit the fruit and veg aisle

3. Eat meat and replace candy with low-sugar nutrition bars

I cannot find it right now, but I am quite sure that in last few weeks there was a post on HN with roughly the same statement, but for high protein diet.

No, the evidence for high protein is the opposite - shortening life by increasing cancer risk: "study cohort aged 50–65 reporting high protein intake had a 75% increase in overall mortality and a 4-fold increase in cancer death risk during the following 18 years" Levine ME, Suarez JA, Brandhorst S, et al.: "Low protein intake is associated with a major reduction in IGF-1, cancer, and overall mortality in the 65 and y…

What I have read you can basically make a trade off with IGF-1.

You can live more years by lowering IGF-1 but you are going to feel older with lower IGF-1.

I would much rather have a longer period of high IGF-1 than a longer overall total lifespan.

No one's going to mention that the title is wrong? The experiment showed that a calorie reduced diet slows metabolism in humans. The researcher specifically says that a long term study that follows participants until their death would be required to see if they live longer.

Personal anecdote : I always ate little and spend most of my life underweight. I look extremely young for my age. I estimate I rarely eat more than 1500 kcal a day When I think about it, most visibly underweight people I know tend to look young. Does anyone have the same observation?

Yes, I have the same observation. I do my own version of "intermittent fasting" diet since 3 years ago and I get the same observation from people, they say I look younger. I feel great :)
