Humm not really. In my perception, as you age and lose collagen, it seems to be that thinner people tend to show more wrinkled skin on their faces. A good example to me is Anthony Bourdain. Here's a picture of him in 2014 and four years later: https://en.wikipedia.org/wiki/Anthony_Bourdain#/media/File:A... http://www.bravotv.com/blogs/anthony-bourdain-comic-book-hun... Don't believe four years alone does that to some…

He doesn't look terrible for being over 60. Don't forget that the restaurant industry is a stressful job with long hours, and he's known for his incessant smoking, drinking, and drug use. Neither of those things lead to a youthful appearance.

Not saying he looks terrible for his age. Just the fact that his face looks way more wrinkled and the biggest factor seems to be weight loss, as not so many years have passed from one photo to another. Also, he doesn't work in the restaurant industry for a long time and enjoys what seems to be a very comfortable life doing nice TV shows.

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…

This calorie amount cannot possibly apply to everyone. For example, if I spend an hour weight training and then later in the day go for a 1-hour job...I'd be in a calorie deficit for that day.

Watch this documentary and see what people say. Hey HN folks, Sometimes science does not explain everything. http://www.lightdocumentary.com/ Trailer: https://youtu.be/Ul82-jaDmlY

No, only the things which can be explained.

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.

What are you basing this assumption on?

The point of the study was that reduced calory intake seems to reduce metabolism, which is already vastly varied between two individuals.

If you're basing your assumption on internet TDEE calculators those are often wildly misleading, and generally overestimate values.

But on the other hand it's extremely hard to know how many kcal you eat, so if he's basing his intake on labels, those are usually too low (within regulation guidelines) because manufacturers want to sound "healthier" than they are.

But to my main point: If you keep as even intake as you can for a few weeks, and you don't lose weight, that is your maintenance, no ifs or buts.

I'm guessing it's less comfortable than you're led to believe from the TV show.

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…

The study suggests plant proteins attenuated that effect. Plant proteins tend to also be accompanied by fiber, while animal protein sources do not contain fiber. In other words, aside from plant protein powder supplements (which still contain some fiber) or tofu, I cannot think of any source of plant proteins that are not accompanied by fiber.

I wonder if that contributes to lower cancer risk, especially colorectal.

IANA scientist, but the article claims new evidence that a reduced calorie diet can slow metabolism, which would impact the “surplus” side of that equation.

But if you don't fulfil the daily macro requirements then from what exactly does the muscle builds?

We were talking about caloric surplus, not macro nutrients.
