Meal Skipping and Shorter Meal Intervals Are Associated with Increased Risk of All-Cause and Cardiovascular Disease Mortality among US Adults

January 24, 2026

| Cardiovascular Health, Diet & Nutrition, Longevity & Mortality

Comment: There is a conflict between the biochemical promise of Time-Restricted Eating (TRE) and the hard reality of epidemiological survival data. Protocols like “One Meal a Day” (OMAD) are promoted for their theoretical impact on autophagy and insulin sensitivity, yet frequently ignores the most important metric: Overall Survival. While short-term mechanistic studies suggest metabolic benefit, […]

Comment: The data presented in this systematic review and meta-analysis of 242,095 participants reveals a stark collision between the biochemical promise of intermittent fasting (IF) and the hard reality of epidemiological survival. While IF is frequently promoted as a metabolic panacea—citing mechanisms like autophagy and improved insulin sensitivity—these theories often ignore the hierarchy of harm: […]

Vitamin B12 supports skeletal muscle oxidative phosphorylation capacity in male mice

Comment: Starting with the clear caveats that this is a preclinical mouse study and a pre-print (has not undergone peer review yet), this is still a fascinating study. We typically categorize Vitamin B12 deficiency as a hematologic or neurological issue, often overlooking or underestimating its structural role in muscle bioenergetics. This study brings the musculoskeletal […]

Comment: A central discrepancy revealed in this research is the failure of Z-drugs, or specifically zolpidem, to deliver on their promise of clinical safety. Despite conventional wisdom suggesting they are a safer class, the data confirms that sedative-hypnotic users as a whole faced a significantly higher mortality risk than non-users. This human clinical data provides […]

Use of Sleep Medications and Mortality: The Hordaland Health Study

Comment: A central issue in sleep medicine is the conflict between the risk of not sleeping, and the risk of taking sedative-hypnotics to help sleep. Most people assume medication induced sleep is better than not sleeping. This 15-year prospective data confirms that daily usage is associated with nearly three times the hazard of death compared […]
