That last link - you find what you're looking for. Pretty sure both groups were protein-starved with the HC worse off.

Let's say the the average athlete in the study weighed 150 lbs. We're told about body weight changes, but nothing about calories consumed, I'll guess 2500/day for a 150 lb. average rider. Using the published percentages, 4 kCal/g for carbs and protein and 9 kCal/g for fat, I get 70g of protein per day. Thus I calculate grams per pound of bodyweight = .47. Most nutritionists use .83 g/lb for mostly sedentary and up to 2.3 g/lb for hard-training athletes. I'll make a conservative estimate for protein requirements of 1 g/lb. of bodyweight. Balancing that out, I get a calorie breakdown of 64:24:12, which is my approximate breakdown. I weigh about 150 these days and consume about 150g of protein/day. I've seen 65:25:10 in the literature.

So basically the study is BS, which is really common with LC studies. They assume no one will look at the details.

Were the study true every serious rider would eat LC. In fact, none of them do except for short periods during training, and most don't even do that. It's like the guy who rode the TdF vegan one year and his performance didn't match what he did when he'd eaten with the team. What works right now is the best we know, right now. They cram the carbs down.

That took enough time, didn't look at the first link.
