Diet plan overview

The 90 30 50 diet plan for intermittent fasting works well for those who prefer time-restricted eating. You still get 90 grams of protein, which is crucial during the eating windows to maintain muscle mass and satiety. The 30 grams of fiber will help regulate digestion, especially important during fasting periods. Meanwhile, 50 grams of healthy fats provide long-lasting energy which is essential in a fasting-focused lifestyle.

This dietary setup can be particularly effective when trying to lose weight or manage insulin levels. Combining intermittent fasting with the 90 30 50 diet enhances the benefits of both, potentially leading to better metabolic health and more effective weight management. Always ensure you are well-hydrated and consult a healthcare provider before starting any new diet regimen.
