To answer these questions and get a real-life perspective, we reached out to our Intermittent Fasting community on Facebook, as well as Intermittent Fasters on Instagram and Reddit. With over 800 people who successfully completed our 21-Day Intermittent Fasting Challenge, we got some great examples to share! 

We interviewed over 30 people (men and women) to understand what Intermittent Fasting results they experienced and summarized the findings below in this blog post.

Spoiler Alert: the Intermittent Fasting results are so inspiring you’ll want to start straight away! 

Intermittent fasting results and weight loss

Undeniably, the most common and also the most desired intermittent fasting result is weight loss

Many diets promise rapid results but often lead to yo-yo effect, when after a tough period, dieters end up back where they started or heavier than before. Intermittent fasting is a great way to reach a sustainable weight loss – not only lose but also maintain the desired weight, as confirmed by most Intermittent Fasters that have done our Intermittent Fasting Challenge. 

So how come Intermittent Fasting is more sustainable than other diets?

The key to sustainable weight loss is being consistent and making your ‘new diet’ a lifestyle rather than doing it temporarily. For many people, Intermittent Fasting allows this given they can still enjoy their favorite meals time from time, as long they adjust the eating schedule.  

For our 21-day Intermittent Fasting Challenge, we suggest starting with a 12/12 fasting schedule, gradually increasing it to 16/8 fasting (click to learn more): a 16-hour fasting and an 8-hour eating window. Taking small steps allows your body (and mind) to adapt to the new eating pattern slowly. It has proven to be the most effective if your goal is to make intermittent fasting a long term habit.

How much weight can you lose doing intermittent fasting?

Are you ready for some numbers?

First, let’s look at what the research says about intermittent fasting weight loss results.

In a 2015 review pooling 40 different studies, participants who did intermittent fasting shed on average 10 pounds in a 10-week period. Another study found that obese adults following an “alternate day” intermittent fasting schedule (eating 25 percent of their daily calories on one day, and eating normally the following day) lost up to 13 pounds (6 kg) over 8 weeks.

Intermittent fasting also succeeds where many weight-loss regimes fail: by targeting and reducing visceral fat. Visceral fat is the stubborn, internal fat packed deep around your abdominal organs. During a period of six months, people on an intermittent fasting diet were able to shed 4-7% of their visceral fat

Sounds great, doesn’t it? But what about the real-life experiences

Average weight loss after one month doing intermittent fasting

For our Intermittent Fasting survey, we started with a question:  “How much weight can you lose in 1 month with Intermittent fasting 16/8?”

Turns out over half (58%) of intermittent fasting beginners lost around at least 8 pounds (3.6 kg) after 1 month of intermittent fasting and 30% reached at least 12 pounds (5.4 kg) weight loss.

Other intermittent fasting results

While weight loss is by no doubt the most desirable Intermittent Fasting result among most of the people who have started our Intermittent Fasting Challenge, it’s not the only benefit you can expect from fasting.  

When we asked people to name other positive changes they have noticed after starting with Intermittent Fasting, we saw several other great benefits.

The most common benefit of intermittent fasting turns out to be increased energy levels

How come less food leads to increased energy? This could be contributed to your body not using the energy to digest food and/or having to think what you should eat next.

People have also experienced multiple other benefits like improved metabolism and immune system, more mental clarity and better sleep.

Gigi Ghobrial

WEIGHT LOST: 52 lbs (23.5 kg)

TIME: 7 months

Intermittent fasting results before and after

“My transformation was Intermittent Fasting combined with going to the gym. I lost a total of 52 lbs in 7 months. 

I started with Intermittent Fasting and transitioned to one meal a day (OMAD) over time. Occasionally I would also do extended fasting. I love the flexibility of being able to enjoy life by eating well. It’s not so much what I eat anymore, it’s when I eat that’s important. Fasting changed my life, specifically my relationship with food!”

Dionna Lofton

WEIGHT LOST: 86 lbs (39 kg)

TIME: 6 months

Intermittent fasting weight loss results before and after

“In six months (from Jan 1 (top left photo) to mid-June (bottom right photo) I went from 223 lbs to 147 lbs, from size 20 pants to size 6 and from size 3XL shirts to L shirts. A few months later, I’m at 137lbs and proudly wear a medium/size 6! 

On weekdays I normally do 18/6 fasting – eat between 11:30 am and 5:30 pm. During this journey, I learned to eat healthier and stay away from breads pasta and fatty salad dressings.

Sometimes during weekends, I would do a water fasting – no food from 5:30 pm on Friday until 11:30 am Monday morning. During this time I would have black coffee with cinnamon and loads of water.

Besides all the weight loss, I got so much more energy now! I’m now running in competitions and coming in first, whereas before I couldn’t even walk without panting. I’m off my heart medication now and can do all these great things now, despite my epilepsy. I feel like nothing can stop me now!”

I started slowly then increased day by day, adding no sugar and Keto diet to my Intermittent Fasting lifestyle. My secret to weight loss is all the above + huge determination and patience.”
