Benefits Of 18/6 Intermittent Fasting

Intermittent Fasting 18:6 method for 10 days

These benefits are due to intermittent fastingâs ability to reduce insulin resistance, promote a self-cleansing program known as autophagy, and facilitate ketosis .

Most intermittent fasting forms promote these processes, but long fasting times are more potent than shorter fasting times. For this reason, you may achieve your goals faster with 18/6 intermittent fasting than with 14/10 or 16/8 fasting.

My One Month On 1: 6 Intermittent Fasting

I have been intermittent fasting since the start of the year. In January, February and March, thee number of days I did it increased and after intermittent fasting for about 12 days in April, I decided to commit to a specific window for May. If youre not sure what Intermittent fasting is, I did a post about it here. In the 18:6 window, I eat for 6 hours and fast for 18, tracking my fasts on an app called zero. I usually eat my first meal around 9 and my last around 3. In May, the only times I didnt fast for 18 hours were once when I ate later than usual for a date night and another time when I had morning cramps and needed to eat before taking painkillers. I fasted for 14 and 17 hours respectively those times.

Okay on to the highlights of my month long experience.

What I Ate And How I Exercised While Doing Intermittent Fasting

Limiting my eating to an eight-hour period of the day seemed reasonable. If I exercised in the morning, my first meal would be an early but large lunch at around 11:30 a.m. By 3 p.m., if I was hungry, I could have a snack. At 7 p.m., I would eat a reasonable-size dinner. No snacking after that.

My first thought was that there was no way I would be able to skip breakfast and still work out. My mind was telling me that I would be hungry. The first few days that I tried it, as I would warm up for my workout, I would have visions of chicken with broccoli from a nearby Chinese restaurant in my head. But once I got into my workout, a funny thing would happen. I would completely forget about being hungry. My body would stabilize and water would be enough to keep me moving.

But by the time I got home from the gym, I was starving. Early on, I decided that was going to be my biggest meal of the day. Sometimes it was a lean shoulder steak with a sweet potato. Other times, I would eat an entire chicken along with two cups of broccoli, and the sweetest bottle of Gatorade I ever had. Or occasionally, I would make a taco bowl out of seasoned ground turkey, cheddar cheese, and tomatoes, or a stir-fry with beef and a variety of peppers. It turned out that my calorie intake and lunch would be anywhere from 800 to 1,000 calories, though this part was not an exact science.

May Reduce The Risk Of Cancer

Numerous animal studies suggest that intermittent fasting may reduce the risk of cancer. Such an effect may be the aftermath of weight loss, reduced inflammation, and insulin levels, which are caused by this eating pattern.

A 2019 review in people with cancer states that fasting reduced some of the side effects of chemotherapy and increased its effectiveness. The review suggests that fasting may deprive cancer cells of nutrients, making them more susceptible to the toxins in chemotherapy .

Eating All Your Meals In A Six Hour Window Could Boost Weight Loss

Intermittent Fasting Guide for Beginners to Pro in 2021

Researchers from the University of Illinois, Chicago, compared 58 adults with obesity selected to be on one of three diets for a 10-week period. One group only ate between 3 pm and 7 pm, fasting the remaining 20 hours day the second ate between 1 pm and 7 pm, fasting 18 hours and the final group ate normally.

The researchers found that at the end of the 10 weeks, both of the groups who fasted lost a moderate amount of weight .

There didn’t appear to be a significant difference between the two groups in terms of weight loss.

This suggests an 18-hour period could be plenty to provide the benefits of fasting, according to Krista Varady, professor of nutrition at the University of Illinois, Chicago and co-author of the study.

“Until we have further studies that directly compare the two diets or seek to study the optimal time for fasting, these results suggest that the 6-hour fast might make sense for most people who want to pursue a daily fasting diet,” Varady said in a statement.

This shorter fasting period closely resembles one of the most popular styles of intermittent fasting known as 16/8, in which participants eat during an 8-hour window each day.

But there’s also evidence that an even shorter fasting period of just 10 hours a day could provide benefits, so more research is needed to directly compare these styles of fasting for weight loss and health effects.

Five Benefits Of 18/6 Intermittent Fasting

Recently, I wrote about the five reasons intermittent fasting works for me. Now I want to share my five favorite benefits of 18/6 intermittent fasting, which is my preferred way to do IF.

Breaking Down The 1: 6

A Beginner

To make this intermittent fasting method more accessible, well break it down into portions of the day. Lets start with your 6-hour eating window: Throughout the day, you have up to 6 hours to get all of the necessary calories and nutrients into your body. You can essentially eat anything you want within reason as long as you stick to the 18:6 schedule.

Most people begin their eating window around noon and conclude it just after dinner around 6 pm. This enables you to get two major meals in and a handful of snacks throughout the day. That should be enough to fill the calories you need. As your fasting window begins to approach, try to slow down and ease your way into fasting.

Now that the 18-hour fasting window has begun, its important to continue to nourish and take care of your body. Water, tea, coffee, and some smoothies are fantastic ways to get through your fasting period. They provide your body with nutrients without disrupting the intermittent fasting process.

As the morning approaches and it nears time to break your intermittent fast, start to ease yourself back into eating. Drink a smoothie or have a coffee something with substance to it. Once you start eating again, begin with gentle foods like soup or eggs. This will help wake up your stomach and ensure that its ready to process food for the day.

How to plan 18:6 Intermittent Fasting for 7 days || How I do intermittent fasting to lose fat

Intermittent fasting was working perfectly for me, and it was easy to follow. I began to think more deeply about why it was working. Was my body changing because I was fasting for those 16 hours each day, or was it simply a trick I was playing on my mind to eat fewer calories? And if it was a trick, would my mind eventually figure it out?

In general, I think intermittent fasting helps people get more in touch with their needs, Varady says. Weve become accustomed to eating or drinking something every couple of hours. Wed never even noticed when were actually hungry or full. So when you go for longer stretches of time without eating, all of a sudden, your body becomes more attuned to it.

In my case, intermittent fasting made me more aware of my tendency to emotionally eat. Getting up early to get my young son to school, it wasnt as if I wanted to have that bagel and soda. I felt I needed that sugar rush to wake me up and get me going. Exercise replaced that without my needing to ride a sugar roller coaster every day.

Studies have pointed out that intermittent fasting can improve insulin resistance, which can help maintain stable blood sugar levels throughout the day. A specific study involving three men suffering from type 2 diabetes, also known as adult-onset diabetes, found that they were able to stop taking their insulin doses after losing weight from the intermittent fasting. These results disprove the widely-held belief that diabetes cannot be cured.

A previous study that Mattson co-authored showed that the previously mentioned metabolic switch can increase the resistance to stress by improving overall brain function and neuroplasticity, a fancy term for the brains ability to adapt and restructure itself throughout ones life.

Older adults who were put on a restricted-calorie diet similar to intermittent fasting have shown improved verbal memory compared to another group who hadnt done intermittent fasting.
