Heal In 2025: Top FOODS & HABITS To Boost Brain Health & REDUCE INFLAMMATION | Mark Hyman

Hyman says the standard 0.8 g/kg is only the minimum to avoid deficiency, and that older people should aim closer to 1.6 g/kg because of anabolic resistance. He adds that about 2.5 g of leucine per serving is needed to trigger muscle building.

Hyman started at 59 and describes muscle loss from the 30s and 40s, sarcopenia and falls as major threats. He says about 30 minutes three times a week is adequate, and that his father regained strength in his 80s.

Hyman describes hormesis as stress that doesn't kill you, such as overnight fasting, exercise, sauna, cold showers and plant compounds. He says these trigger processes like autophagy and heat shock proteins.

Hyman says DNA methylation tests measure biological age and that eight weeks of aggressive lifestyle and dietary change can reverse it by about three years. He says he is 63 chronologically but 43 biologically.

Hyman cites data that meaning and purpose may add about seven years of life, comparable to eliminating heart disease and cancer. He also says loneliness is a risk factor as great as smoking, and he describes weekly calls with longtime friends as profoundly helpful.
