Whatever works for you. Buckwheat sounds horrible to me as I dislike its taste (I had tried very many things in my life) and it’s very very very carby (even legumes are better and they are still high-carb and moderate protein, way too low protein for me personally but some of them are extremely delicious, at least). If I don’t do keto, I rather fall back to my pre-keto carb intake but it’s just me, I truly don’t feel great with a lot of carbs (over 80g was way too much for me many years ago).
The only buckwheat for 1-2 weeks is insane, good you don’t do that. Never heard about it and I am an European (we say middle, some people say eastern, I know the grain, it’s historically important but almost no one eats it as far as I know. its flour makes nice plant-based thin pancakes though! vegans struggle so much with eggless pancakes and buckwheat flour just glue it together and it doesn’t tear. why do I know such things when my diet is half-based on eggs I don’t know). But I just don’t read about new diets unless it arrives on this forum. I know what is good for me.
It seems it works for you, well for certain important things, IDK how you feel otherwise. Your grain intake isn’t huge, it would be too high for me and too low for my SO but maybe it’s right for you. Now, at least.
Why is it better than doing keto when you can and eat an off meal here and there? I am just curious, if this works for you, no need to put effort to change it but maybe it’s not for long term…? If I have carbier meals, I totally need to eat stricter whenever I can. You clearly isn’t that type though. But if you think you MUST stick to keto or just should eat higher-carb all the time, well it’s not true for me and I suppose, for many. The lower my average carb intake, the better, at least to some point, I would get cranky being super low, too restrictive. So going on and off keto all the time is still better than eating mere low-carb (way higher than my keto). Maybe on/off bothers some people for various reasons.
As I never ate much buckwheat (but I did eat oat and that’s higher protein higher fiber too. I dislike that too except when mixed with eggs so my experiences are tiny there as well), I only can have an educated guess about how it would feel to me. As far as I know, all starches are starches to me, a little extra protein doesn’t help. Sugars are usually worse but animal sugars are fine (I am a huge dairy lover). Vegs are sugary and/or starchy so I try to avoid them (except in tiny amounts where they are harmless but enjoyable).
I see the buckwheat diet (or just that site. dietsin? omg, I am not surprised then) is very much against red meat (unlike Eastern Europe I suppose. I only know about Hungary, we have campaigns since years for eating more pork, quite successfully). I don’t like that part, personally. But if you don’t eat red meat for some reason anyway, it doesn’t matter. But the diet has too much of these modern health ideas, lean meat, especially chicken or fish, no red meat (lean or not, ruminant or pork, nope), yogurt, much vegs… Sounds silly to me but I don’t say it’s not great for the right people. Just health articles tend to be stuck there and act like it’s the healthy way for everyone.
I wish Greek yogurt would be a good protein source but it’s mostly fat and sugar to me, its protein content is modest but we all have different needs and tastes. And not all Greek yogurt is 10% fat, apparently. Ours typically is.
I don’t like blindly following stuff but if it feels normal and natural for you and you enjoy enough the diet and you feel right… It’s an option for sure!
