The Basics and Benefits of Intermittent Fasting

You might be wondering what all the excitement is about Intermittent Fasting and you're probably aware that going too many hours between meals can cause a drop in blood sugar that leads to headaches, fatigue, and difficulty concentrating. While that's true, new research shows that planned periods of Intermittent Fasting (IF) or Intermittent Energy Restriction (IER) can be really good for your health! This is not about starving yourself to lose weight. Instead, IF aims to give the digestive system a break from food, which allows the body to cleanse itself. To be truly restorative, IF is matched with a similar break from mental and physical activity.  

Though clinical research is still in the early stages for both animal and human studies, several health benefits have been identified. Researchers are investigating different types of IF protocols for both healthy adults and those who are living with obesity, heart disease, diabetes, and metabolic diseases.

Benefits of Intermittent Fasting

  • Increased sensitivity to insulin and leptin, which can lower risk of diabetes, heart disease and even cancer

  • Better regulation of hormones associated with appetite

  • Enhanced metabolic use of stored fat

  • Lower triglyceride levels, which decreases risk for heart disease

  • Reduced inflammation

  • Enhanced awareness of appetite and cues for eating

  • Simplicity! Planning 2 meals rather than 3 per day helps keep things simple during the workweek.

Suggestions For Intermittent Fasting

During an Intermittent Fast, drink plenty of water, keep exercise to low intensity, and avoid stress such as the kind created by work deadlines or caretaking for family. For breaking your fast, always choose unprocessed, whole foods including fresh fruits and veggies, beans and legumes, whole grains like brown rice and quinoa, and the best quality fish, meat and dairy.  

 

The 16/8 Method: involves skipping breakfast and restricting your daily eating period to 8 hours (e.g., Noon – 8 PM), then fasting for 16 hours (8 PM to 12 PM the next day).  

The Weekly/Bi-weekly 24-hour Fast: involves a 24 hour period of fasting for one or two days per week or every other week: Last meal at 6 PM Monday, no food but plenty of water until 6 PM the next day.

The 5:2 Method: involves choosing any two non-consecutive days of the week and eating only about 600 calories on those days:  Tuesday 600 calories; Thursday 600 calories, rest of the week eating regular, healthy meals.

Young children, pregnant and lactating women, and the elderly should use caution when deciding to do IF and speak to a holistic health care professional. Your Naturopathic Doctor can help you determine if this is a good approach for you and which is the best intermittent fasting regimen to meet your health goals! Also be sure to check out this informative acomprehensive guide on intermittent fasting https://www.perfectketo.com/guide/intermittent-fasting/.
