Not saying most or all of these are not true, but this list liberally mixes causation and correlation, without any sort of reference to the controlling for second and third-order effects. So if you stay up late AND eat shitty food AND don't exercise, yep you'll be at risk of weight gain, diabetes and a shorter lifespan, and maybe lack of sleep plays a role but you can't say it's the root cause.
