Compartmentalization. Plenty of stimulant and H and other drug abusers in tech.
Sugar and alcohol are addictive and addictions are irrational and you can't use rational objective thought to get out of a situation that is inherently irrational and subjective, like addiction.
Essentially zero H users, for example, have never heard the news that H is bad for them. Can't just concentrate hard enough to get out of an addiction, they don't work that way. So it is with alcohol, sugar, carb binging in general, etc.
Cite needed LOL. They're great for weight gain, which is not much of a medical necessity in the current year although there are special situations (cancer patients, etc)
If you don't eat an essential nutrient (vitamins, minerals, etc) you'll eventually get sick and die. If you don't eat a very high carb diet you'll ... be healthier and have better blood test results? Nobody never died from having a single digit A1c blood test result or a blood glucose no longer going up to 250 anymore LOL.
Do we have any evidence that low carb diets have a positive effect on longevity compared to these diets?
Compared to the Standard American Diet, low carb may be far better as it can eliminates refined carbs with no nutritional value, but the optimal diet may include a moderate amount of carbs from healthy whole food sources.
I’m actually following a low carb diet myself for almost 1 year and agree it has benefits, but think ultimately it’s place is as a stepping stone. I will probably begin to incorporate healthy whole foods as I am exercising more than I was when I started and it’s hard to get enough calories.
It'll be the same discussion, addicts trying to rationalize away the science and statistics.
