On the fringe between VLC and LC are there any gotchas? In particular living just outside ketosis? Would you want to pad that with a few extra grams of carbs?
If through experiment you decide that ketosis happens for you below 48g of carbs. Would it be wise to eat at 55g of carbs or would it better to stay clear of that amount and take 70-80 grams of carbs? Not really a debate between VLC and LC but more a question about the human body. Can it handle living just outside of ketosis with the least amount of carbs to stay out of ketosis?
Why not carb cycle. I run fine on low carbs as long as I am not doing anything to demanding. I find I recover better when I reintroduce moderate carbs post workouts. Rest of the time I just have trace carbs or green veggies while upping my fat. There is also something called the Anabolic Diet which does 5-6 days of a VLC diet in ketosis followed by a 1-2 days ( usually the weekends) with higher carbs.
Personally, I would go as high as I could if I was still getting good results. For me that is more to the VLC end but YMMV. I think it is good for everyone to be in ketosis here and there, but whether you stay there for long depends on your metabolism.
