Vital Signals
Short, clear briefings on longevity science, fitness, nutrition, medicine, wellness culture, and consumer health claims.
Poor sleep tracks with inflammation, chronic disease, and mortality risk. The signal is meaningful, but the strongest outcome evidence is observational—not proof that a better sleep score adds years to life.
Carnivore eating may change weight, symptoms, and biomarkers for some people. The direct evidence is still too thin to establish broad benefit or long-term safety.
GLP-1 medications are being studied for effects that may extend beyond weight loss, including cardiometabolic outcomes and behavior-related pathways.
Low-intensity aerobic work can support endurance and metabolic health, but consistency matters more than obsessing over perfect zones.
Wearables can reveal patterns, but sleep scores, HRV, and recovery numbers are estimates rather than diagnoses.
GLP-1 medications may do more than reduce appetite for food. Early clinical trials, real-world data, and preclinical research suggest they may also affect craving, reward, alcohol intake, and substance-use patterns - but the science is still developing.
