Effects of A Ketogenic Diet, Time-Restricted Eating or Alternate-Day Fasting on Ambulatory BP

A sub-analysis of a Spanish randomized clinical trial showed that diets with varying ketogenic potential had differing impacts on blood pressure (BP). Ninety six participants with obesity (BMI >30 kg/m²) were assigned to one of five dietetic interventions: early time-restricted eating (eTRE), late time-restricted eating (lTRE), modified alternate-day fasting (mADF), ketogenic diet (KD), or a control Mediterranean diet (CG). All groups achieved significant improvements in anthropometric measures, but BP responses differed. The mADF group showed the most effective improvements in 24-hour ambulatory BP monitoring, while lTRE also demonstrated some benefits. In contrast, KD, eTRE, and CG did not produce statistically significant changes. The findings suggests that Low-calorie diets with different ketogenic potentials can reduce BP in people with obesity, especially mADF. Source: https://academic.oup.com/eurjpc
