Losing weight long term on LCHF

Before and after
Does LCHF work long-term? I received an e-mail from Ramsey, who knows for sure:
The E-mail
Hey There Doc,
First, let me start by saying I’m a very big fan of what you have been doing these past years. My name is Ramsey, I’m 26 years old and have been LCHF for about 6 years now. I have always been an athlete, but it appeared as if my body didn’t receive the memo. I simply ate like a giant Panda (kinda looked like one too). One day while looking in the mirror, I said to myself “why are you fat? You play countless sports and are in great shape”. It then dawned on me, DIET! From that point on I started cutting the carbs and eating real food. I’m pleased to say that I have gone from roughly 250 lbs (113 kg) to 163 lbs (74 kg)!!! I’ve maintained this weight off for 6 years now, and the amount of activity I do is drastically less, due to sports injuries. I am no more special than anyone else – if I can do it, so can you!
Good luck, friends.
-Ramsey
Congratulations, Ramsey!

The initial weight-loss took approximately 1 year.
That being stated, let's get to the questions: =)
#1 How often and how much do you eat?
Given my current lifestyle (Musician working nights) I live out of hotels traveling the world. When I'm on vacation my body composition actually improves being that I prepare all of my food. Working in hotels can be very good, but at times, very bad. Good in the sense that I have sometimes have access to quality food and as much as I want, FREE! Bad in the sense that at times, I have no say in the type or quality of the food that is offered to me. kind of an oxymoron.
-When on vacation: I typically fast after waking up for a few hours 2-3, from there I cook some bacon in butter and add cheese and eggs. After that I'll usually eat some sort of meat with veggies in the evening. In between I may have some nuts or make my favorite drink (Avocado, heavy cream, blueberries, cinnamon and nutmeg, DELICIOUS!
-While at work: I usually wake up early to get to the buffet (2:30 pm), being that dinner is a la carte and will not have access to food after work, 2am. I typically stick to the meats (chicken, lamb, brain, pork, liver) and cheeses, as well as heavy cream sauces. I enjoy broccoli/cauliflower casseroles (no potatoes, just cheeses/butter/cream). I always have my coffee with butter/heavy cream and I drink a ton of sparkling water, because it makes my tummy feel funny. ;)
#2 what do you eat and what do you not eat?
-I am not perfect and occasionally fall into temptation and enjoy life. That being said here are foods I try to avoid: Grains, legumes, artificial sweeteners or anything that is sweet for that matter, fruit (exception of berries, lime, lemon) and most tubers (Although i'm not against them).
-Foods I eat: Meats, nuts/seeds, high fat dairy, vegetables growing above ground.
#3 how often do you train and what do you train?
-Once upon a time I was a decent athlete, playing Football, Wresting and fighting MMA. Due to injuries (Torn ACL and Meniscus, broken nose) I am a lot more restricted in what I can do. As of now, i simply do calisthenics, specifically (Convict Conditioning, mixed with gymnastic movements and just being a kid at heart and moving around randomly anywhere I'm at. I do not do cardio (unless you count me sliding on stage while I shake my toosh. =)
#4 Did you have any issues with loose skin?
-I do not have issues with loose skin, hover there is a little bit of give to it given how heavy I once was.
#5 how long did it take before you started to see your abs?
-That came at about the 6 month mark.
#6 Did you keep track of your body fat %?
-I once did, I believe the lowest I achieved was 12 %.
#7 Do you know you body fat % now?
-I could not tell you today, but I feel more muscular based on my calisthenics, i would guess around 10 %.
#8 How tall are you?
- 5'10
To sum it up, I basically follow what the good doctor has said. We are constantly learning and finding out new things, let's just be open and question it without cult-type bias. What works for me may not work for you, and vice versa. Take into consideration all of the environmental variables (diet, stress, sleep, genetics, goals etc..)
Good luck all, if you're on this site then you are already a step ahead of the game.
Nap time,
