I mentioned a few weeks ago that I was taking part in "Dry January". I didn't make a big song and dance about it, but I decided to go for a calendar month or so with no alcohol. A few people have asked me about my experience, so here are a few points. Why take a break from drinking? Alcohol is an interesting topic. As a drug it is widely accepted in society, central to so much of our socialising and leisure. There seem to be lots of health benefits - so we are told - yet there are also a lot of problems in terms of health, relationships and lifestyle that come from drinking. Over a few years I'd begun to become aware and then concerned that I was drinking too much and too regularly. I am in a busy and stressful job and sometimes a glass of wine after work to relax is really helpful. But over time, one glass became two. Two glasses became ....I might as well finish the bottle. A habit got established....and was starting to get too e...

If you don't cause the shift, the body has no point in adapting. Hence, it suggests that taking carbs during training (which they agree improves performance) would not allow that shift, so you adapt less.
But then, they go on to talk of two studies that show the contrary. So the answer to the titular question seems to be a no.
"Although these studies are valuable, we need to question how
relevant they are to the real world since no one, especially
athletes, is likely to start a training bout, or indeed a race, in
the overnight-fasted state. In addition, both the Akerstrom
et al. (1) and the De Bock et al. (3) studies used active but
not specifically endurance-trained participants. This is an
entirely reasonable approach since greater changes are observed during a training program in relatively untrained than endurance-trained individuals. However, these results may not be applicable to endurance-trained athletes. In addition,
there is a need to conduct similar studies in females, especially as females have been shown to have less activation of AMPK during exercise than males...
...Rather than CHO ingestion having a negative effect on training adaptations, it is possible that the opposite may actually occur in the real world..."
