A distinction without a difference, perhaps? I don't think anyone "needs" gluten/sugar in their diet. But I do like a "reasonable" measure of carbs, some of which come from whole grains, which I know to be anathema to keto guys such as yourself (except on cheat days, of course ). In any event, whatever works, eh? But I do think it's a good thing you don't put butter in your coffee and stir it with bacon.
My point is more that the diet is sustainable on its own because you are still eating plenty of good food. Also one can sustain the diet and still have a cheat every once in a while. People may not want to give up certain foods and I can understand that. A juicing diet for example is short-term and not sustainable or eating only soup (there are diets based on both). Crash diets are made for 1 week solutions and those never end well. The problem with Keto are those that "sell" it as eat all the bacon and butter that you want and lose weight. I approach it more from a medical/nutritional standpoint.
By sustainable, I meant that people would be willing to adhere to it. Just guessing here, but I suspect that for a lot of people, if they abstain from carbs in any meaningful way for any length of time, there will be a rebound effect resulting in more cheat mulligans. In my own case, as I've said before, I am no longer drawn to added sugar. Cakes and cookies have absolutely no hold on me. The only time I ever have a token amount is when I am pretty much forced to do so, such as at birthday parties and so on. Once a week, I have the one-inch tail end of a croissant with someone who has the remainder. My only other vice is a multi-grain encrusted baguette, which I buy occasionally. It is made with white flour but the entire surface of it is encrusted with several whole grains. The coffee shop/bakery I go to bakes it especially for me because it is no longer offered. I cut it up into 2-inch slices while still oven fresh and freeze it. A single baguette lasts me almost 2 weeks. That is the extent of my cheating. (Pretty minimal, right?) All other carbs are either fruit, vegetables and a reasonably limited amount of whole grains. It is a diet I thoroughly enjoy and can adhere to without effort. Yeah, crash diets are meant to crash. In any event, isn't juicing pretty much a sugar diet? Regardless, be it soup or juice, I can't see a no-protein/no-fat diet ending well. Yes, I do think yours is a more measured approach than some of what I've read on the Internet about keto.
True enough. But it pales in comparison to having its surface space entirely encrusted with whole grains in their natural form. I will have a slice after dinner when I return from the gym today. Living the life. (If they ever decide to stop baking it for me, I may have to resort to a life of crime.)
Sustainable is the key. I once went on a diet of oatmeal and broccoli. That was it, and it worked too. Was it bit gassy though.
Great for closed-door negotiations; time is on your side. Even so, you may wish to reconsider your friendship with whomever recommended it to you.
