🧠 Sarcopenia = The biggest metabolic crisis of aging

Losing 1-2% of muscle per year → decreased metabolic rate
Muscle = 40% metabolic source + a large number of mitochondria (energy factories)
Muscle building not only burns fat → it also affects hormones, immunity, and repair capabilities.

👉 It’s not that you’re not depressed because you’re old, but that you’re aging faster if you’re not depressed.

👩 Women: Hormonal Breakdown During Menopause

Decreased estrogen levels lead to loss of bone, muscle, collagen, and cartilage.
Progesterone levels almost zero → estrogen imbalance → decreased muscle repair ability
Results: Loose skin, wrinkles, muscle atrophy

👉 Estrogen is not only a female hormone, but also a muscle repair factor.

👨 Men: Hormonal changes after age 60

Men have a 4 times higher risk of ALS (amyotrophic lateral sclerosis) → After menopause, the risk for men and women becomes 1:1.
Progesterone = potent neuroprotective agent → combats neurodegeneration

👉 Men who don't supplement hormones experience both muscle and nerve degeneration .

🧪 Cholesterol = Raw material for muscle hormones

Statin side effects = muscle damage
Reason: Cholesterol is a raw material for the production of testosterone, DHEA , progesterone, and estrogen.
Low cholesterol → insufficient hormones → accelerated muscle loss

👉 It's not that fat is bad, it's that when there's not enough fat, bad things happen.

🌙 Melatonin = the guardian of mitochondria

Melatonin comes in two forms: one to aid sleep and the other to protect mitochondria.
The older you get , the more melatonin levels drop tenfold , leading to poor sleep and low energy.
Methods to increase melatonin levels: Sunlight (infrared rays), firelight (candles/campfires) → Artificial light ( LEDs /blue light) will reduce melatonin production.

👉 It's not that I can't sleep, it's that I'm not sleeping deeply enough for deep repair.

🧬 Hormonal communication pathway: pituitary gland → gonads

Pituitary gland releases: luteinizing hormone ( LH ) + follicle-stimulating hormone ( FSH )
Age increases → LH / FSH surge → Hormonal imbalance
Increased melatonin levels can suppress LH / FSH levels, thus balancing gonadal function .

👉 Good sleep = stable hormones = well-maintained muscles

🛠 6 Ways to Preserve Muscle (Original Suggestions)

① Exposure to infrared radiation → Increases melatonin levels ② Resistance training → weight training / resistance band / bodyweight exercises ③ Animal protein intake : 0.8–1.2 grams per kilogram of body weight. ④ Sufficient cholesterol → meat/dairy/butter ⑤ Supplementing with pro-hormone → Pregnenolone ( 30–100 mg ) + DHEA ( 25 mg for women / 100 mg for men ) ⑥ Avoid GLP-1 diet pills → they can cause severe muscle protein loss.

👉 It's not about losing weight quickly, but about losing weight healthily while preserving muscle.

🧾 In conclusion: Don't assume that "getting older = natural muscle loss" anymore; it's actually a result of "a triple failure of hormones, nutrition, and training."

Starting today, a targeted muscle protection strategy, a hormone reset plan, and a metabolic reboot route based on infrared radiation, protein, and resistance training will lay a solid foundation for your body!

Don't let the myth that "getting old means certain death" hold you back. True health comes from knowing how to supplement correctly, exercising regularly, and maintaining a healthy lifestyle! 💪🦴🧬
