Intermittent Fasting Fails to Boost Health Without Calorie Reduction, Study Finds

• A new German study (ChronoFast) challenges claims that time-restricted eating alone improves metabolic health.
• Researchers found no significant improvements in insulin sensitivity, blood fats, or inflammation when calorie intake remained constant.
• The study involved 31 women with overweight or obesity, carefully matching calorie and nutrient intake across different eating windows.
• Energy balance (what and how much you eat) remains crucial for metabolic health and weight loss, according to the findings.
• Meal timing did influence circadian rhythms and sleep patterns, but not metabolic health directly.

Why It Matters: Metabolic health depends on calorie balance, not just when you eat, new study confirms.
