I think it's fair to say that while a keto diet can be maintained long term, it has to be very carefully managed and supplemented with extra vitamins.
Well, I'm taking them out of an abundance of caution, but the only thing I've really cut out is sugars, rice, wheat, sugary fruits, and the carbiest of root vegetables (but I'm eating moderate amounts of carrot, onion, radishes and so on). Low carb does
not have to mean butter and bacon. I'm now eating
more green vegetables: cabbage, kale, broccoli, cauliflower, courgettes, celery, tomatoes, olives and green beans.
What am I missing out on?
The human body is designed to operate on a wide range of foods
Evolved, not designed. We may be having a labelling squabble here. If I said "Cooked Palaeolithic plus some non-lactose dairy" rather than keto, how are we looking?
and in general requires carbohydrates for energy.
Why
requires? I have more sustainable endurance now than I did 3 months ago.
Yes, you can convert fat to energy, nobody says you can't but there is a lot of questions raised over the long term health effects of a high fat, high protein diet.
But what are the answers?
In my case it's a moderate fat, moderate protein, low carb diet. I've reduced my food intake, it's just that I've lowered carbs much more than fat or protein, both of which provide essentials acids.
I think I've said several times that I wouldn't necessarily suggest high fat, minimal carbs as a
maintenance diet, but dropping carbs has certainly working for losing body fat, particularly visceral fat, and I hope we can agree on the health benefits of that.
Even the Bulletproof people tell you not to eliminate ALL carbs and they're about as pro-keto as you can get.
It's practically impossible to do so, and nowhere in here am I advocating it. I'm happy to call it very low carb, Paleolithic, or whatever doesn't imply 90%/6%/4% full keto.
Added to all of which is that carb based foods have a wide range of nutrients that are more easily absorbed into the human body than in other forms.
Fruits, maybe, but those are seasonal. Potatoes, possibly, but we didn't evolve to eat those, nor wheat, nor rice. And see the veg list above, plus a multivitamin a day. What am I missing out on?
I have no doubt that it works for you and I wish you all the best on it, but a healthy, balanced diet is always going to be better for the general health of the vast majority of people.
I'm still unclear on what's unhealthy about a diet based around loads of fresh veg, nuts, some dairy, fish and chicken. I've looked, but all I can find is woo-science handwaving, and unsourced assertions.
I'm happy to follow the science, but I have to actually see it.
