Two Workouts Target Root Cause of Most Diseases.
In 2023, Mark Hyman from the UltraWellness Center reviewed research on mitochondria, the cell powerhouses that convert food to energy. They decline with age, causing fatigue, brain fog, muscle weakness, and inflammation linked to diseases like Parkinson's, diabetes, heart disease, and cancer. Exercise triggers mitophagy, clearing damaged mitochondria, with studies showing 20-30% better mitochondrial function in active people vs. sedentary.
Artificial Sweeteners Wreak Havoc on Metabolic Health.
In 2025, Huang-Pin Chen and a team from National Cheng Kung University reviewed studies on low-calorie sweeteners like aspartame, sucralose, and stevia. They examined how these affect metabolism, heart health, cancer risk, and gut bacteria, pulling data from human and animal studies on blood sugar, insulin, and microbiome changes.
Meal Timing Matters Just as Much as What You Eat.
A 2025 narrative review in Nutrients by Reytor‑González et al. explores how when we eat interacts with our internal clocks—impacting metabolism and weight regulation. Aligning meals with natural circadian rhythms—eating more in the morning/early afternoon and less at night—may help prevent obesity and metabolic disease, even without restricting calories.
Betaine Shrinks Fat, Revives Gut, and Reboots Metabolism.
A 2025 animal study in Frontiers in Nutrition by Wang et al. found that giving high-fat–fed rats betaine (1.5% in drinking water) for 8 weeks led to less body fat, improved blood lipids (lower triglycerides, higher HDL), and better glucose tolerance—all without cutting calories.
