Risks and Benefits of Fasting for Health and Fitness

Fasting is a practice that involves abstaining from food or drink for a certain period of time. There are different types of fasting, such as intermittent fasting, which involves alternating periods of fasting and eating, and extended fasting, which involves fasting for more than 24 hours at a time. Here are some potential risks and benefits of fasting for health and fitness:


  1. Nutrient deficiencies: If you’re not careful about what you eat during your feeding periods, you may not be getting all the nutrients your body needs, which can lead to deficiencies and other health problems.
  2. Dehydration: Fasting can lead to dehydration, especially if you’re not drinking enough fluids during your feeding periods.
  3. Low blood sugar: Fasting can cause your blood sugar levels to drop, which can lead to dizziness, weakness, and other symptoms.
  4. Overeating: Fasting can lead to overeating during your feeding periods, which can negate any potential benefits and lead to weight gain.


  1. Weight loss: Fasting can help you lose weight by reducing calorie intake and promoting fat burning.
  2. Improved insulin sensitivity: Fasting can help improve insulin sensitivity, which can reduce the risk of type 2 diabetes and other metabolic disorders.
  3. Reduced inflammation: Fasting has been shown to reduce inflammation in the body, which can lower the risk of chronic diseases like heart disease and cancer.
  4. Increased lifespan: Some research suggests that fasting may increase lifespan by promoting cellular repair and reducing oxidative stress.

It’s important to note that fasting is not suitable for everyone, especially those with certain medical conditions or who are pregnant or breastfeeding. If you’re considering fasting for health or fitness purposes, it’s a good idea to talk to your doctor or a registered dietitian to make sure it’s safe and appropriate for you.
