I could not agree more. Thank you my apologies, my comments were meant to open a productive debate. But instead I got a bit of a personal bashing for not bowing to the status quo that seems to be going on here. As the nice man said He clearly can not understand what it is I am dong here as he clearly fails to see any possibility of there being any thing untoward with the HFLC diet a lot like my fanatical friend.
A question that I feel is very important. Given the history of supposed fantastic diets and miraculous cures. It is possible the HFLC diet is little more than yet one more fad. I look at the sudden turn around in medical science from fats being bad to fats being good all most over night as breath taking. I wonder why this amazing change of events strangely came along with a increase of Type Two Diabetes.
Some years ago I heard a story of a wall in a small town in America. After a big storm a faint image of what looked like a man with long hair and a beard and what looked like a halo around his head on the wall. Soon enough the image was thought to be that of Jesus Christ and people came from all over to see it and prey next to it. Some claimed to have been cured of illness because of it. This went on for many years making the small town very popular. Then one day there was another big storm when the dust settled clear as it could be on the wall was a painted advert for cigarettes with a depiction of a long hair, beard cowboy and his ten gallon hat..
I would respond with just a couple of points.
Your friend may be over-zealous and may have gone OTT with his dietary changes and weight loss. Not one single person on here knows how accurate that assessment is without actually seeing him and discussing his regime with him. Assuming he is a capable adult, he has made a lifestyle choice which may or may not serve him well over the longer term. Every single one of us does that every day - including you.
Many people comment that when they lose weight in particular, the hear unpalatable feedback from their friends and sometimes relations. Sometimes that is well meaning and bourne out of the changes the onlookers see, and are unfamiliar with. Some of us, once we pass spring chicken stage, find it takes a little longer than immediately for our skin and outer appearance to catch up with the improvements in our inner well-being, because, just as an example, our skins don't shrink quite so readily or rapidly. And thirdly, some people's friends would love to be achieving what they are and are jealous. The massive majority are feeding back supportively fearing our wellbeing, nit not always everyone.
To be clear, I am not drawing lines between your post and any aspect of that comment.
Over time, you will come to understand which of you or your friend was closer to reality with your feelings and his actions. I really do hope your friend remains well; not because I desperately want you to be wring, but because I would like him to be healthier and enjoying the benefit of the changes he seems to have made. Change isn't easy.
From my own perspective I have reduced my carb intake and when I, myself, got very slim I increased my fat intake a bit in order to stabilise my weight and all other health markers.
Incidentally, the swing from low fat to fuller fats has been a slow burn process, with many more health care professionals understanding that the timeline for increasing diabetes and obesity is closely connected to the time-frame for recommending low fat products. Sadly, though, there has been a great deal of resistance of HCPs "coming out" for full fat before the official guidance begins to support it. In some ways that is understandable; such is the litigious society we live in.
These days I rarely get the "you look a bit drawn" feedback because people are more used to seeing me thinner. Where I am now, I spend around half of the year (winter), with summers in UK. I had actually had a very difficult lead up to returning here last month (a bit later than usual) and wasn't looking forward to being told I looked pale and drawn. In my opinion I did. I'd had some surgery and no sign of sunshine for months on end, as opposed to warmer, sunnier climes here and everyone else glowing. But, the reality couldn't have been more different. I had further refreshed my wardrobe so that I am no longer wearing anything too big, or very roomy any more. I am wearing well fitting underwear, clothing and swimwear and enjoying it. Actually, I was told I looked fitter than the butcher's dog.
So, I think your assessment of your friend's position is a very complex one, which time will tell upon. In the meantime, I hope you too remain well.
