Since you asked about links, here's one to what seems quite a comprehensive and informed site on the science of low-carb, by an enthusiast with a PhD. Having skimmed it, it does seem that adequate energy for both aerobic and anaerobic activity can be derived from a low-carb, medium protein and high-fat diet - as one would expect from historic human eating patterns - but that there is a definite process of physiological adaptation to get to that point from a more typical Western higher-carb regime. During adaptation one would indeed expect there to be temporary issues with exercise performance and general feelings of well-being. Only the individual can decide if that is indeed where they want to get to, and how to cope with the adaptation process in the interim,

> My story:
>
> Been on this wellness journey for over 6 yrs, doing heavy weight lifting (4
> X/wk) and 'many' diets to try to shed this last bit of fat off my body (last
> time I measured, I was at 18% body fat).
>
> Have been working out fasted for well over a year (thanks, Burt!), but
> usually only 10 hrs as I WO at 6am and my last meal is usually around 7pm.
>
> In August, I chose to start eating low carb, high fat, simply because I was
> tired of being hungry all the time (if I dare broke my fast w/carbs, I was a
> goner!) (thanks, Ellen & Carolyn!).
>
> Mid September, I discovered I had above-normal blood sugars.

> I stopped using Fast5 in an effort to get this new WOE under my belt and to

> I stopped my 4X/wk weight training in mid-October and switched over to a
> "Slow Burn" style of lifting (work out once every 7-10 days) I got about 6
> work outs in before I realized I needed to quit because of a shoulder
> injury. I was not in the gym for 6 wks.

> 2 wks ago, I went back to the 4X/wk weight training. Eating HFLC (less than
> 25g Carbs daily), my blood sugars have come down nicely. The first week
> back to training, they went high, then crashed low (122/77). I was
> initially consuming a glucose food post-WO, then, after a week of weight
> lifting, got brave and cut that out and just had my 20g protein/4g carb
> shake. The first day, I was fine! No hunger for over 5 hrs! But I
> couldn't duplicate it! The next time (this Monday), I had the same protein
> shake post-WO and was hungry an hour later and had another half a shake. I
> got the nibbles all day (and my blood sugars were higher than usual: 98).
> Tuesday, I had the larger protein shake but then got this weak/wobbly
> feeling within an hour. Desparate, I cooked up and ate 70g of sweet potato
> (loaded w/butter). I just couldn't attain the 'satisfied' feeling all day!
> I ate nuts and cheese (anything quick at hand) to try to get that satisfied
> feeling. I finally gave in to tortilla chips.
