Hello! I hope everyone had an excellent Labor Day weekend!
I wanted to make good on my promise to write about intermittent fasting as I hope it’s something that will benefit at least a few of you out there! For the past 5-6 years, I’ve included some type of intermittent fasting (IF) in my routine. I can honestly say that I notice a huge difference in my energy levels and metabolism compared to periods when I don’t intentionally include IF in my regimen.
In the past few years, fasting has become rather trendy. However, IF has quite a bit of research behind it, which pulls it out of that “fad diet” category (not to mention many religious groups have practiced fasting over long periods for centuries and it’s working for them). IF changes the body’s metabolic processes on a cellular level and therefore has important effects for both the body and brain – cool!
Here’s how IF works:
Normally, when the body needs energy, it uses glucose first as a rapid energy source. Once the available glucose has been used up, the body begins to break down fat to fuel our metabolism. Protein is the last to be broken down and is usually not utilized unless the body is under extreme conditions (i.e. starvation).
During a period of fasting/caloric restriction, the body is able to use up it’s glucose stores and begins to break down fat for energy. We can use fat from any part of the body that has excess fat stores like subcutaneous fat (a.k.a. “that stubborn belly fat”), visceral fat (fat that builds up around your abdominal organs), and intramuscular fat.
By significantly reducing calorie intake during IF, our body is able to use the spare energy to boost its processes of detoxification in the liver and kidneys. Waste removal from our cells also increases, and our body as a whole is able to operate more efficiently.
Some of the many benefits of IF include1:
- Optimized cell functioning and cellular repair (this is called “autophagy” which literally means “self-eating” – eating the bad stuff, anyway)
- Decreased insulin resistance = lower risk of type 2 diabetes mellitus
- Reduced oxidative stress and inflammation in the body
- Increased fat loss while maintaining lean body mass
- Improved brain function and neuroprotective effects
Types of intermittent fasting include:
- Weekly fasting (5:2)
- Limit calorie intake to 500-600 calories for 2 days out of the week.
- Daily fasting (16:8)
- Eat all of your normal daily calories within an 8-10 hour window and fast (0 calories) for the other 14-16 hours. 16:8 is the most common, but for females and those with difficulty regulating blood sugar, a 14-hour fast can be more ideal.
- 24-hour fast
- Only 0-calorie liquids allowed for a 24-hour period. Can be done several days per week, but best to alternate fasting days with healthy eating days.
With all of that being said, IF is appropriate for most people. Be sure to consult your doctor, registered dietitian, or physical therapist before trying intermittent fasting. It is important to eat an adequate amount of calories in a balanced diet for all of your meals. It’s also extremely important to maintain proper hydration (water & electrolytes), especially with longer fasts.
I have continued to do 14:10 fasting during my chemotherapy, most days of the week. There is some research that IF can reduce chemo side effects2 and I continue to feel very strongly about making sure my insulin/blood sugar regulation is under control to prevent this tumor from taking advantage of any opportunity to grow! I am very aware of my overall calorie intake as my body needs plenty of nutrients to stay strong during treatment. This is NOT a time for me (or any cancer thriver) to be in a calorie deficit!
Please feel free to leave questions about IF in the comments section below! Stay tuned for more updates on my personal journey later this week as I complete taxol/carbo #6!
