Our Findings

Editor's Rating4.50

Our testing team was impressed. DoFasting is unique because it offers a subscription app along with safe and helpful supplements that aid in a person’s fasting weight loss journey. Cheaper than rival fasting apps, DoFasting stands apart because of its superb exercise and healthy recipe libraries.


  • Offers many physical and mental health benefits
  • Incredibly easy-to-use app
  • Convenient Fasting tracker
  • Robust library of healthy recipes and workouts
  • Supplements are vegan, organic, gluten-free, and non-GMO
  • Take 75% off a 6-month plan


  • Not for those with certain health conditions or a history of eating disorders
  • No trial period
  • No barcode scanner for logging food within the app

Intermittent fasting is a diet trend that many celebrities and influencers promote. But this diet has roots in prehistoric times when hunters and gatherers spent hours or days searching for food to survive. Both doctors and dieticians swear by intermittent fasting’s research-confirmed health benefits, including weight loss, mental sharpness, optimized hormones, lowered inflammation, and enhanced longevity.

The idea of going long hours or even days in between meals may seem impossible, but intermittent fasting is pretty flexible. There are many different ways to structure an eating and fasting pattern. However, intermittent fasting is not for everyone, especially those with certain health conditions.

Our team put DoFasting’s intermittent fasting app and weight loss supplements to the test to see if these products hold up to the hype. Read our full review below to determine if DoFasting is safe, effective, and suitable for your lifestyle.

Our Top Picks

How we evaluated DoFasting

DoFasting is one of many intermittent fasting weight loss programs, but how does it compare to other options?

After six weeks of following a 16:8 fasting schedule, our testers found they felt more focused, slept better, and had shed an average of three pounds per week. We identified several major criteria to evaluate DoFasting’s app and its supplements: safety, cost, customer experience, and ease of use. The effectiveness our team experienced while testing DoFasting is attributable to how the company generally excels in each of those areas.


7.5 / 10

DoFasting’s app and its optional supplements are based on credible research concerning weight loss. The app categorizes fasts based on experience level — beginner, intermediate, and expert — which is helpful if you’re unsure where to start.

Intermittent fasting has several health benefits, but it can result in some side effects, such as hunger, nausea, headaches, or fatigue. DoFasting’s supplements help alleviate some of these side effects by elevating energy levels and curbing hunger pangs.

Because intermittent fasting involves extended periods spent not eating, this particular diet is not ideal for everyone. Intermittent fasting may not be the safest option if you’re pregnant or breastfeeding, have diabetes, have a history of eating disorders, or have gastroesophageal reflux. We recommend talking to your doctor first before committing to intermittent fasting.


8.6 / 10

DoFasting does not list app subscription costs on its website: You must complete a questionnaire to find out the pricing options. As of now, DoFasting offers three autorenewal plans: 3-months at $2.96 per week, 6-months at $1.97 per week, and an annual plan that costs $1.27 per week. There is no free trial, but the price is lower compared to the competition.

Wrapped up in the cost is access to helpful features, including over 5,000 healthy recipes, a library of workouts, a fasting tracker, and the capability to log your food, weight, steps, and water.

If you purchase an app subscription, you gain access to discounted supplements and membership-only supplements.

Currently, DoFasting only sells two supplements through its website: DoFasting Box - Essential Fiber Complex that costs $69.99 for a one-month supply and Apple Cider Vinegar Gummies that cost $63.99 for a six-month supply. These supplement costs are in line with other options, but it’s difficult to compare because so many supplements exist on the market.

Customer experience

8.3 / 10

DoFasting offers a safe and effective way to lose weight with its app and supplements. You can customize your fasting method based on your lifestyle; track food, water, and steps; explore workouts tailored to your fitness level; and cook from an array of healthy meal options. The supplements help you burn fat, reduce hunger, and boost energy levels.

DoFasting also allows for a great deal of flexibility. But when it comes to weight loss, flexibility may not be what everyone needs. If you prefer having social support, structured meals or workouts, regular check-ins, or educational guidance, DoFasting is not recommended.

Ease of use

8.7 / 10

The prominent feature of the DoFasting app is the fasting tracker. You can choose a fasting method that fits your lifestyle or engage in challenge mode. And, if you so choose, the app will send daily reminders about your fast.

The other app features are really intuitive. Logging weight, steps, and water is a quick process. One of the best features is the workout library. The app guides you through every exercise with a video tutorial, and it keeps track of time.

The app’s only downside is the food-logging feature. If you eat a DoFasting recipe, you can easily log the food. However, the DoFasting app lacks a barcode scanner, which is standard for other weight loss apps. So if you eat a protein bar or store-bought hummus, you have to manually enter all of the nutritional information. The food-tracking feature could be further developed.

DoFasting’s supplements can seamlessly become part of your daily routine. Whether you mix a powder or chew on a gummy, the supplements are no-fuss and do not require special equipment or prepping.

What is intermittent fasting?

Intermittent fasting (IF) is a weight loss approach in which you cycle between periods of eating and fasting. Like any weight loss diet, IF works the same way: You consume less food energy than your body burns. Between meals — during a fast — the body uses up its sugar stores and burns fat.

IF severely limits calorie intake during certain days or time periods. Popular approaches to IF include:

  • 5:2 fasting involves eating five days a week and fasting for two non-consecutive days.
  • Daily time-restricted fasting entails eating within a certain period of the day and fasting for the remaining hours. The most popular daily time-restricted fasting is the 16:8 method, in which you fast for 16 hours and eat during an eight-hour window.
  • OMAD fasting stands for One Meal A Day. It can be particularly difficult to get a day’s worth of nutrients in a single meal, so we would only recommend this to experienced fasters.

There are a number of health benefits associated with IF, including:

  • Increased mental sharpness
  • Improved blood pressure and resting heart rate
  • Decreased risk for obesity and obesity-related diseases
  • Reduced inflammation
  • Enhanced longevity

Intermittent fasting is not suitable for everyone, especially if you’re pregnant or breastfeeding, have diabetes, have gastroesophageal reflux, or have a history of eating disorders. We recommend consulting your doctor before committing to IF or any other new eating regimen.

Who should use DoFasting?

DoFasting is a health and wellness company that provides a subscription-based app for intermittent fasting and several weight loss supplements. The DoFasting app helps you monitor your fasting and lose weight with various features:

  • A fasting tracker that indicates your hours of fasting and your eating window
  • Water, food, step, and weight tracker
  • A library of workouts
  • Over 5,000 healthy recipes that you can tailor to your meal preferences
  • Articles about intermittent fasting
  • Challenge mode if you’re so inclined to test your limits

The app aims to help you lose weight by providing healthy recipes to cook, workouts to get you moving, and a custom fasting method that fits your lifestyle. The DoFasting supplements work in conjunction with the app to provide needed nutrients and to help suppress hunger, making your fasting regimen more tolerable and effective.

DoFasting is for someone interested in intermittent fasting and looking for exercise and meal ideas. DoFasting allows for flexibility because you can choose your fasting method, what you eat, and how you workout.

If you’re looking for a more structured weight loss plan, DoFasting may not be the best option. It is also not ideal if you prefer having social support as part of your weight loss program. The company does not have any coaches, guides, or dieticians to aid with motivation or accountability.

In general, fasting is not recommended if you’re pregnant or breastfeeding, have diabetes, have a history of eating disorders, or have gastroesophageal reflux. Before committing to a new eating regimen, we recommend talking to your doctor.

The DoFasting app

Dofasting App

The DoFasting app is free to download, but you need to purchase a subscription to gain access to the features. DoFasting offers three subscription autorenewal plans — 3-month, 6-month, and annual — but the company does not list any prices on its website. In testing DoFasting, we gained access to subscription costs, which are broken down in the below chart.

The more months you pay for, the cheaper the DoFasting app is.

A subscription provides access to all the app’s features, including:

  • Customizable fasting options
  • A fasting and eating window tracker
  • A weight, water, step, and calorie tracker
  • Over 5,000 healthy recipes
  • A library of workouts for all levels
  • Some educational articles about wellness and intermittent fasting
  • Challenge mode

After you purchase a subscription, the app prompts you to choose the type of fast you want to adhere to. Fasts are categorized based on the level of difficulty. For example, a beginner fast is 12:12, in which you fast for 12 hours and have a 12-hour eating window. A more advanced fast would be 5:2, in which you fast for two non-consecutive days and the remaining five you eat like normal.

Once you choose your fasting type, the app begins tracking your eating window. The fasting tracker is helpful, especially if you use the app’s reminders.

You can also customize numerous parts of the app: your fasting method, food preferences or dietary restrictions, the type of workouts you want to do, and whether or not you want to track water, calories, or steps. The best and most extensive app features are the workout and healthy recipe libraries.

Overall, the app is straightforward to use, enables you to keep track of a lot of data, and is chock-full of resources to eat healthily and exercise.

Canceling your DoFasting subscription

The cancellation process depends upon how you purchased the app — on DoFasting’s website, on Google Play, or with an iOS device. We recommend reviewing the company’s cancellation instructions, which could be more straightforward.

DoFasting is also incredibly strict about refunds and does not seem willing to grant them. The company will only consider a refund if you contact customer support within 14 days of your purchase. You must provide proof of payment along with detailed information and visual proof showing how the product was faulty.

DoFasting supplements

When taken daily, DoFasting’s supplements increase your energy, help lower bad cholesterol levels, nourish healthy gut bacteria, suppress hunger, and kickstart the fat-burning process.

The Essential Fiber Complex

$69.99 for a 1-month supply, Available in their online shop and with a subscription

The Essential Fiber Complex Box is the company’s flagship weight loss supplement. It promotes feelings of satiety, allowing you to prolong your fast while avoiding hunger pangs. It also helps regulate cholesterol and maintain a healthy colon. The Essential Fiber Complex Box is non-GMO, gluten-free, sugar-free, and vegan.

The Essential Fiber Complex Box contains two plant-based fibers: cellulose and glucomannan. Both cellulose and glucomannan purportedly prolong feelings of satiety and promote weight loss; however, further investigation is needed to determine the ingredients’ efficacy. A few studies have shown that taking these supplements has no effect on weight loss or hunger/fullness.

There are many fiber-based weight loss supplements on the market, so it’s difficult to say if The Essential Fiber Complex Box is worth it.

Apple Cider Vinegar Gummies

$63.99 for 3 bottles, Available in their online shop and with a subscription

Apple cider vinegar has been a health and wellness staple for centuries. Research suggests that it has many benefits, including lowering blood sugar, promoting a healthy digestive system, and calming acid reflux. DoFasting’s Apple Cider Vinegar Gummies integrate these benefits with vitamins B6, B12, and folic acid. These gummies are gluten-free, non-GMO, vegan, and free of artificial colors and flavors.

The gummies are a great alternative to drinking apple cider vinegar because — in liquid form — apple cider vinegar erodes tooth enamel and can damage the esophagus. It is possible to water down apple cider vinegar, but the taste is too strong for some people.

There are other apple cider vinegar alternatives on the market. Most notably is Bragg’s ACV Supplement in capsule form. At $19.99 for one bottle, Bragg’s price is comparable to DoFasting’s.

Keto Cycle Fuel

$45.80 for a 5-pack, Only available with a subscription

Keto Cycle Fuel is a blend of MCT, collagen, and electrolytes — a combination that increases energy levels and speeds up ketosis. Ketosis is a fat-burning metabolic state and is traditionally achieved by means of following a high fat and low carb diet, like the ketogenic diet. Ketone drinks, like Keto Cycle Fuel, are a worthwhile alternative to achieving ketosis without dietary alterations.

The Keto Cycle Fuel comes in two flavors: chocolate or vanilla. You dissolve the powder in water, stir, and then drink it an hour before your first meal or an hour before/after your first workout.

Keto Cycle Fuel is not available on DoFasting’s online shop. You can only buy this supplement if you purchase an app subscription.

BHB Ketone Boost

$29.16 for a 6-month supply, Only available with a subscription

BHB Ketone Boost is a powder that you dissolve in water and drink 30 minutes before meals. Ketones are alternative fuel supplies in the form of fat — instead of glucose — for the body to use. By increasing ketone concentrations, you can up your fat-burning, increase your metabolism, boost mood and energy, and decrease your appetite.

BHB Ketone Boost is available in two flavors: peach and raspberry. This supplement is not available on DoFasting’s online shop; you can only buy it if you purchase an app subscription.

Twice-As-Easy Bundle

$79.83 for a 1-month supply, Available in their online shop and with a subscription

The Twice-As Easy Bundle includes The Essential Fiber Complex Box and Apple Cider Vinegar Gummies.

DoFasting’s All Supplements Bundle

$129.99 for a 1-month supply, Only available with a subscription

DoFasting’s All Supplements Bundle includes The Essential Fiber Complex Box, one bottle of the Apple Cider Vinegar Gummies, and two boxes of BHB Ketone Boost.

Getting started with the DoFasting app

To get started with DoFasting, go to the company’s website or download the app on your phone. The sign-up process takes less than five minutes, and you can expect the following.

Step 1: Questionnaire

The brief questionnaire asks basic information like height, weight, and gender; how familiar you are with intermittent fasting, when you’re hungriest, what your ideal weight is, and whether or not you are breastfeeding, pregnant, or diabetic.

After you answer the questions, DoFasting presents you with a timeline so you can see how quickly you can reach your ideal weight.

Step 2: Sign up and pay

You then must enter your email to see the pricing options. You can sign up for an autorenewal subscription in increments of three months, six months, or 12 months. While you enter payment details, a timer counts down.

Step 3: Start your plan

After you purchase a plan, you will experience some extreme upselling. DoFasting pushes its exclusive membership-only supplements, but you can buy these later on after you purchase a subscription.

You’re then prompted to create a login and download the app. You can begin fasting right away; however, you should follow the suggested preparation tips first.

Using the DoFasting app

The DoFasting app is straightforward and easy to use with several features, including:

  • The fasting/eating tracker
  • A library of workouts
  • Over 5,000 healthy recipes
  • Some informative articles
  • A place for you to log your daily weight, calories, water intake, and steps

The fasting/eating tracker is the prominent feature. You have to manually begin and end your fast and eating window, but that’s easy to remember because you can set a notification. After each fast, the app asks how you’re feeling, and, hopefully, fasting becomes easier over time.

Based on the questions you answered during the sign-up process, DoFasting calculates how many calories you should eat a day to lose weight. If you choose to count calories, you may be better off using another app because there isn’t a barcode scanner. So if you eat any packaged items, you need to input all nutrition information manually. But you can easily add individual ingredients — like an egg or an apple — or DoFasting recipes.

DoFasting’s educational content collection is underwhelming. As of now, there are about 20 articles, so you probably won’t spend a lot of time with this feature.

By far, the app’s best features are its recipe and workout libraries. The app has over 5,000 recipes, and you can filter your search by dish type, preparation time, or calories. You can also save your favorite recipes for later.

The workout library provides an array of options to choose from based on the type of workout, skill level, the time you have, and what body part you want to focus on. The app guides you through the entire workout from start to finish with video tutorials, and it also has a built-in timer. Additionally, you have options to move to the next workout, pause, or skip the rest break.

Privacy considerations

DoFasting is incredibly transparent with how it handles personal data when you visit the website or use its mobile app. The company’s privacy policy is easily accessible on its website.

DoFasting collects personal data from its users to provide goods and services. The company collects non-personally identifiable information, such as your IP address, geographical location, browser type, OS, device type, etc., through the use of cookies and other technology. You can manage cookie collection and disclosure of personal data through links on the website, but if you block cookies, you will be unable to use all of the website’s features.

The company may disclose personal data to any of its subsidiaries, insurers, or professional advisers as reasonably necessary for maintaining insurance coverage or in court proceedings.

How DoFasting stacks up to the competition

As a whole, weight loss apps are incredibly prevalent, and intermittent fasting apps are no exception. DoFasting is unique with its fasting focus and other weight-loss offerings, including healthy recipes, exercises, and supplements — something other fasting apps do not provide. The DoFasting app is reasonably priced and rivals competitors in particular areas, as explored below.


Zero’s free app includes a fast timer, a journal, educational content, and weight-loss statistics. The company’s paid version, Zero Plus, costs $69.99 a year. Zero Plus includes everything that the free version does, as well as advanced statistic tracking and the ability to submit questions to the company’s expert panel. Zero Plus also has a free, one-week trial period.

Zero Plus is slightly more expensive than DoFasting’s yearly subscription, which costs $60.96. But Zero Plus is more robust in terms of its fasting-oriented offerings. You’ll better understand how intermittent fasting works, and you’ll have greater flexibility with IF customization. With that said, DoFasting’s app includes two key features that Zero doesn’t: thousands of healthy recipes and a phenomenal workout library.

If you want to immerse yourself in fasting, then Zero is the way to go. But if you’re looking for a more holistic, intermittent fasting weight loss program, then DoFasting is ideal.


Fastic boasts the world’s largest fasting community with over 17 million app subscribers. Similar to DoFasting, Fastic is fasting-focused with a holistic weight loss approach. You can download the free version that includes a water and step log and a not-so-intuitive fasting tracker.

The paid version, Fastic Plus, includes a recipe book, daily and weekly challenges, access to Fastic social media channels, expert guidance, educational content, and healthy habit tips. For a year-long subscription, Fastic Plus costs $74.99, which is more expensive compared to DoFasting’s $60.96.

If a community and social support are something you desire, then Fastic may be worth the price. But in terms of app offerings, DoFasting has similar features for a lower cost.


Award-winning app Lifesum enables complete customization of your weight loss journey. The free app is quite comprehensive and easy to use. You can log water, steps, and food by searching the app’s database or using the barcode scanner. You also have access to hundreds of healthy recipes.

The paid version of Lifesum costs $49.99 for the year. Lifesum rivals DoFasting because you can choose to adhere to a specific diet, like intermittent fasting, ketogenic, Mediterranean, sugar detox, or countless others.

If you’re unsure if fasting is right for you, Lifesum is a happy medium because you can try IF. But because Lifesum is not fasting-centric, it doesn’t provide helpful fasting tools as DoFasting does.
