Spending a median of US$2 million a yr on an anti-aging routine, Johnson claims he now ages slower than some kids. He explains: “the tempo my physique accumulates ageing injury is lower than the common ten yr outdated.”

A lot of Johnson’s age-reversal strategies are questionable, contain dodgy science, and have recognized unwanted effects.

Whilst you cannot cease the ageing course of, and the gradual decline our our bodies expertise as we advance in years, there are some issues we are able to all do—at no cost—to take care of our well being as we age.

What does Johnson do? And is it scientific?


Johnson reviews fasting for 23 hours a day. He then eats one meal a day: 2,250 energy of nutrient-dense meals “custom-made” to his physique’s wants.

Consuming for time-restricted durations within the day can have a constructive impact on how we metabolize vitamins, irritation ranges, hormonal regulation, and cardiometabolic well being (blood sugar, triglycerides, ldl cholesterol, blood strain, BMI and waist circumference).

Nonetheless, a Spartan-like meals consumption can impair how our physique responds to sugar (often called glucose tolerance). And it is not essentially any simpler for weight upkeep than decreasing calorie consumption at every meal.

Massive-scale, long-term human trials are wanted to verify the restricted risk-benefit findings of fasting.

Acid peels

Johnson has weekly acid peels (which use a gentle acid to exfoliate the pores and skin) to take care of a “youthful glow.”

However you can’t easy sagging facial pores and skin or take away deep scars or wrinkles. Acid peels additionally include dangers, together with organ injury, an infection, scarring and swelling.

Plasma infusions

Cleopatra apparently took every day baths in bitter donkey milk. To maintain this lavish behavior, she had a herd of 700 donkeys. Bitter milk accommodates lactic acid, a naturally occurring alpha-hydroxy acid (AHA) that exists in lots of modern-day exfoliants. So this concept was grounded in fundamental science, a minimum of.

Throughout the sixteenth and seventeenth century, “Countess Dracula” aka Elizabeth Bathory allegedly resorted to serial killing to quench her thirst for youthfulness, bathing within the blood of her younger victims.

The hunt continues with cryotherapy

Fountain of youth fixations have impressed many modern anti-aging traits. Publicity to chilly is a agency favourite.

Some analysis suggests this might have advantages regarding longevity, by slowing mobile degeneration, stimulating collagen and elastin manufacturing, rising the metabolism, and decreasing irritation.

Dutch motivational speaker Wim Hof contains chilly water immersion as one of many three pillars of his Wim Hof Methodology to “improve mind-body connection.”

Athletes resembling Cristiano Ronaldo use cryotherapy, exposing their our bodies to extraordinarily chilly temperatures for 2 to 4 minutes to lower the indicators of ageing and improve their common well being.

Nonetheless, the dangers of cryotherapy embrace bone fractures, frostbite, nerve injury, bleeding, cramping, swelling and pores and skin infections.

So what can we do to age properly?

Two of the extra mainstream anti-aging strategies that Johnson recommends are the every day self-care habits of sleep and train.

He has a strict sleep schedule that entails retiring to mattress at 8pm, with a one-hour wind-down in a darkened room.

Adults report poorer sleep high quality and problem with the ability to sleep for lengthy sufficient as they age. Sleeping an excessive amount of or too little is related to a larger danger of weight problems, coronary heart illness and untimely demise.

Growing an everyday sleep routine, decreasing bed room distractions resembling cellphones, and exercising commonly can all assist to alleviate sleep issues.

Train, usually cited as a surprise drug for wholesome ageing, is one thing Johnson takes very severely. He does a “Blueprint” exercise that features specifically designed every day strategies, in addition to high-intensity interval coaching classes, climbing and enjoying sport.

From center age onwards, all of us have to train commonly, to extend our muscle mass, bone density, energy, endurance, coordination and steadiness. One of many best well being dangers for older folks is falling, which steadiness, flexibility, endurance and energy coaching may help scale back. Bodily exercise can convey social advantages in older adults if undertaken in teams, and there are well-known psychological well being features.

Small modifications in sleep, food regimen (consuming loads of greens, fruit, wholegrains, wholesome fat, and sufficient protein), and train can help wholesome ageing, decreasing the prospect of early demise, and serving to us all to steer an energetic and impartial life in our senior years. Now that’s one thing value investing in.
