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…

Couldn't using intermittent fasting solve this problem? So having "caloric surplus days" for building muscle, basically.

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?

I lost ten kilos last year and my friends have been asking me how I managed to look like I'm getting younger while they are getting older (for the record, I'm also in my mid-thirties and one of the few who has yet to have children).

Based on your height & gender, 1500 kcal is either a normal caloric intake or a significant deficit.

I've been experimenting with it for two years, along with a high-nutrient diet based on vegetables (almost no refined foods). I just did about two weeks at 1,000 calories per day and am on day 3 of a water fast. I'll increase the caloric intake next week. I hope it's safe. Some else posted this link in a comment, and it's worth reading too: https://www.theguardian.com/science/blog/2009/jul/14/ageing-...

Fasting is largely safe, but you have to monitor your weight loss. If you lose weight too quickly, you're losing a lot of muscle mass and this can adversely affect your heart. http://www.nytimes.com/2004/10/10/magazine/chest-pain-recent... Keep up some cardio and exercise to keep heart's muscle mass and dial down calories slowly.

IIRC, I lost 65 pounds at a rate of about 8-10 pounds per month.

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…

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.

Fasting for a month is possible, but not drinking water will probably kill you within a few days. Here is a medically-supervised fast of over 300 days.

I've done a lot of fasting, and the main cause of failure on a fast for me is not drinking enough water.

I have been on a reduced calorie diet (one meal a day) since the start of february and have lost over 10 kg of both fat and muscle.

10KG? in 6 weeks? that sounds like a dangerously high amount of weight loss.

It's really fast, but it depends what the starting point was. A lot of it could have been just water, if they were obese to begin with.

I went from 66 kg to ~55kg, eating only one lunch a day plus some fruits. I think I've gotten way too thin, that around 58 kg would have been better, and that's why I'm thinking of starting to supplement. I also have kept on exercising plenty, muay thai and boxing, and that might be why I've lost this much weight, even though I wasn't obese when I started.

That's what they suggest at the end of the article.
