Now that’s strange, because according to my favorite expensive clothing brand, then this season’s new colorways will provide a performance leap that was hitherto only dreamt of 20 years ago
Type 2 diabetes is diagnosed by a high amount of insulin resistance, as determined by a glucose tolerance test.
A keto diet actually induces or exacerbates insulin resistance, but is touted to “regulate” blood sugar and insulin, simply because you are not taking in any more carbohydrates, which can reduce blood sugar spikes. Blood sugar spikes are not the cause of insulin resistance, otherwise a keto diet would fix it, not cause it.
One cannot simply conflate eating sugar with T2 diabetes and insulin resistance simply because ingesting sugar or carb causes a blood sugar spike and insulin release. Insulin resistance improves with higher and higher percentages of carb intake, and is proven by numerous studies and in real life.

Great discussion about fueling (CHO) research in latest Trainer Road podcast/youtube vid. Coach Jonathan Lee basically re-states the position of the OP of this thread - stating “I feel very strongly that the largest contributing factor to [modern biking performances/results] is fueling. It’s allowing athletes to…have a level of performance that is so high.”

Glad you enjoyed the discussion! 
And yet pros still have weigh ins. 
What do weigh ins have to do with starvation diets?
Historically weigh-ins are directly linked to starvation diets.
I do think nutrition is way better than what it was… but weight is, and will always be, an issue for top endurance athletes IMO.

Well weight is a pretty big factor in bike racing, particularly on courses with a lot of elevation gain.
There obviously needs to be a balance between the highest level of performance from proper nutrition while still being at a lower weight. Obviously some athletes sacrifice their physical performance striving for a lesser weight and that is a problem.

But the weigh-ins aren’t trying to catch people being too light. Is it against the rules? I assume they do it (these days, at least) for the stats so the athletes can size up their competitors before the race, and so the keyboard warriors have something to argue over.
Not just weight but REDS
They do it because if a rider comes into training camp too heavy they are suspected of not putting in the training and aren’t selected on the team.
Not sure why that would even need to be a secret. If a rider comes into a training camp at 15 lbs over what their race weight should be, it may not be possible for them to complete their workouts while losing a large volume of weight.
I don’t know this as any kind of fact but I think it would be a reasonable policy.
