When combined with a nutritious diet and a healthy lifestyle, 16/8 intermittent fasting can be a lasting, safe, and easy strategy to improve your health. However, it should not be used in place of a well-balanced diet rich in whole foods. Furthermore, you can be completely healthy even if you do not practice intermittent fasting. Though 16/8 intermittent fasting is generally seen to be safe for healthy adults, you should check with your doctor if you have any existing health conditions. This is especially important if you have low blood pressure, diabetes, or a history of eating disorders. If you're attempting to conceive, or are pregnant, or nursing, you should avoid intermittent fasting. Consult your doctor if you have any worries or suffer any negative effects during fasting.
