Oddbean new post about login | logout I disagree that exercise is unnecessary especially when you get to be my husband and my age. Sarcopenia is an issue as you age.
Exercise for well being sure, exercise for blood glucose reduction through glycogen use, no. I’ll bet I’m at least twenty years older than you. Pervasive insulin is the root cause of adipose tissue accumulation and the only way to reduce insulin presence is to reduce blood glucose levels as many hours per day consecutively as you can.
I’m in my 50’s. Muscle mass plays a significant role in insulin metabolism and glucose regulation.
Yeah, I’m much older. lol. True, but insulin presence in the blood blocks the metabolism of lipids entirely, making it literally impossible for adipose tissue utilization no matter how much you exercise. This is why starvation in a person with metabolic syndrome causes the body to utilize muscle and leave fat reserves behind, also why there are middle age people exercising consistently and experiencing “stubborn” fat. It’s important to first clear both metabolic pathways, then exercise for wellness and vitality. By age fifty most Americans are experiencing a rising A1C and the associated weight gain, few know how to fix it, and the medical establishment is no help at all. I quit medical school decades ago because of the AMA. It’s criminal what they’re doing to the population.
To some degree sarcopenia is part of the aging process. Seventy is not twenty, I’m reminded of that every day, but still I’m no slouch physically. Activity is certainly an important component of vitality into old age.
Sarcopenia is preventable as you age with weight training (exercise).
Preventable, no. Mitigated to some degree? Yes. Hormones are a symphonic entourage that changes with age. Adding ten trumpets won’t fix the overall tune! I do appreciate you and enjoy the discourse.
