I follow Don Laymon (longtime protein researcher) on protein, so I was interested in his carb views, finally covered in a newer video interview.
He doesn't have a strong preference for either high-carb or high-fat, but recommends about a daily 100 carb grams for the typical sedentary person. Say, 20-to-40 carb grams per meal, or even match carb and protein grams per meal.
He says that the muscles prefer to oxidize fat up to about 65% maximum exertion--above that, you start to need to burn carbs. If you play tennis or do HIT, like he does, then you'll need more carbs.
He considers the average person's 300 carb grams per day consumption to be a prescription for obesity and diabetes.
He also thinks that calories need to be reduced as people age--maybe going as low as 1,400 calories per day.
Dom Layman is a friend of mine, and we've had a number of discussions about all this. He's more low-carb than you might think. I'm not sure about the 65% maximal exertion figure. I've got some US military unpublished studies showing there is a point of exertion at which carbs are required for optimal output. But these studies weren't done on carb-adapted subjects. That makes a big difference, and I don't know that there are any studies on maximal output vs carbs on truly carb adapted subjects. I'm also not sure I agree with the 1,400 kcal/day for aging people. Depends upon a lot of variables, so can't really be a one-size-fits-all recommendation.
He had a gleam in his eyes and excitement in his voice when he mentioned green beans for dinner, so I suspect he is a minimalist when it comes to carbs.
