How Fast You Should Actually Lose Weight
The safe rate is proportional, not absolute: 0.5 to 1% of your body weight per week. For a 110 kg adult that is far more than for a 60 kg one.
How Big a Calorie Deficit Lowers Your BMI
A 500 kcal daily deficit does not produce half a kilogram a week indefinitely. Expenditure falls as you get lighter, and the curve flattens.
BMR and TDEE: the Calorie Numbers That Matter
Basal metabolic rate is roughly 60-70% of daily energy use. Add activity and digestion and you get TDEE — the number that decides whether weight moves.
Fiber, the Microbiome, and Longevity
Fiber feeds the gut bacteria linked to healthy aging, and a high intake is associated with lower all-cause mortality; here is how much you need and where to get it.
Caloric Restriction and Lifespan
Caloric restriction reliably extends lifespan in animals; here is what the CALERIE trial showed in humans, what epigenetic clocks add, and who should not try it.
The Mediterranean Diet and Longevity: The Evidence
The Mediterranean diet is the most thoroughly studied eating pattern for longevity, and PREDIMED showed it cut major cardiovascular events by about 30%.
Coffee and Longevity: What the Research Shows
Moderate coffee is linked to lower mortality, diabetes and liver disease: what the large studies show, how much counts as moderate, and who should cut back.
How Much Protein You Need After 40 to Keep Muscle
Protein needs rise with age: about 1.2–1.6 g per kg of body weight a day protects against sarcopenia, spread across meals, from both animal and plant sources.
Glycation and AGEs: How Sugar Ages Your Tissues
Glycation turns excess blood sugar into AGEs, cross-linked compounds that stiffen skin and blood vessels as you age.
What People Eat in the Blue Zones and What Works
The Blue Zones diet without the myths: what these longevity hotspots actually eat, which parts hold up in research, and how to copy the pattern at home.
