DoFasting is a weight loss program that leverages intermittent fasting. The brand has a paid phone app to track your fasting, a “smart scale”, and several supplements for weight loss.

In this article we’ll review DoFasting based on medical research and tell you whether we believe the program is worth your money, and if it’s a safe and effective option for sustainable weight loss.

Does Intermittent Fasting Cause Weight Loss?

Since the DoFasting program is predicated on intermittent fasting, it’s valuable to first analyze medical studies on whether intermittent fasting can cause weight loss.

A systematic review of intermittent fasting’s effects on weight loss was published in 2020 in a leading Canadian medical journal. The researchers analyzed 41 individual medical trials on the topic.

Intermittent fasting was found to be very effective for weight loss. In the 27 trials which tracked weight, every group lost weight on average. The weight loss ranged from 0.8% of baseline weight to 13% of baseline weight from the beginning to the end of the trials.

One of the surprising findings was that “weight loss occurred regardless of changes in overall caloric intake.” This suggests that intermittent fasting has positive effects on metabolism that cause patients to burn more calories at rest.

We can conclude from the research that intermittent fasting overall is effective for weight loss.

DoFasting App Review

The most popular part of the DoFasting program is their weight loss app. It costs $11 per month on a 6-month plan, and $33 per month on a 1-month plan.

The app offers different fasting options, such as “beginner-friendly” options like a 14-hour fast. As the patient advances and becomes more accustomed to fasting, there are options such as a 24-hour fast that the app may suggest, for up to two total days per week.

This approach seems reasonable to us, because there isn’t yet a medical standard for the most effective type of intermittent fasting. The linked meta-review from the previous section included various types of fasting: 16-hour fasts, alternate day fasts, “5 and 2” day fasts and more.

The app also contains workout programs and healthy meal recipes, which can be a nice perk but we feel to be relatively unnecessary as these are easily accessible online for free.

We don’t see any harm in using the DoFasting app, but we find it to be somewhat of a waste of money. Tracking hours fasting is very easily achieved manually. If a patient decides to start intermittent fasting for 16 hours per day, all they need to do is remember (or note down) the last time they ate.

In fact, tracking intermittent fasting is much simpler than tracking calorie intake, which many dieting patients already do without an app. Tracking calories can be cumbersome and requires food scales, and multiple data inputs to a phone. Tracking fasting is easy in comparison, especially since most of the medical trials proving success for intermittent fasting didn’t even require participants to track or restrict calories.

DoFasting Smart Scale Review

DoFasting sells a “Smart Scale” which is currently unavailable for purchase in the U.S. at the time of writing. The company claims their scale can track various metabolic parameters, such as metabolic age, skeletal muscle mass and visceral fat.

We don’t find any of this information to be very useful, and we don’t believe it provides much value above a basic weight scale (though it’s great for branding).

Metabolic age, which isn’t a clinically-defined term, seems to measure a patient’s base metabolic rate (how much calories they burn at rest) to the average for their population.

We know from medical research that weight training can increase base metabolic rate, so tracking metabolic age is just an indirect way of tracking fitness, and we have no proof of accuracy for this device.

DoFasting publishes no proof or research that their device can accurately track measures such as visceral fat.

Similar to the app, we don’t see any harm in this device for consumers set on purchasing it, we just don’t find that it provides much valuable information. We know that losing weight improves all metabolic parameters for overweight patients, and a regular scale which likely costs a fraction of the price can track weight just fine. 

For patients on an intermittent fasting diet, tracking weight is the most important thing; secondary data points like visceral fat will decrease with weight loss, and there is no clear benefit in tracking them directly.

DoFasting Appetite Suppressant Review

DoFasting Appetite Suppressant ingredients

One of the supplements that DoFasting sells is an appetite suppressant. We find this to be an unnecessary product category for patients on intermittent fasting, because as the previously-discussed research already highlighted, patients didn’t even need to track their calories and still lost weight on intermittent fasting. Clearly appetite was not a hindering factor to weight loss.

The supplement itself has one active ingredient: glucomannan. This is a type of fiber that we discussed at length in our review of weight loss supplement Leanbean. It is proven to be effective for inducing weight loss, but no more so than other types of fiber.

A 1-month supply of DoFasting Appetite Suppressant is $62.99 which is an absurd price for a fiber supplement in our opinion.

We would recommend a basic psyllium husk fiber over this product for patients looking to further optimize their weight loss, and it would come at a fraction of the price.

DoFasting Appetite Suppressant also contains filler ingredients like natural flavor, which is a broad descriptor which encompasses a wide variety of chemical compounds. Without knowing what compounds were used it’s impossible to determine if the product is safe.

The supplement also contains citric acid which is a flavoring and preservative agent we recommend avoiding, because it’s manufactured from a fungus and has contributed to whole-body inflammatory conditions in some patients according to several medical case reports.

DoFasting Apple Cider Vinegar Gummies Review

DoFasting ACV Gummies ingredients

DoFasting sells an apple cider vinegar (ACV) gummies supplement, which they claim can “improve your fasting experience” without explaining how.

We recently published a research article proving the lack of health benefits of apple cider vinegar gummies. The dosage of ACV in gummies is too low to have a proven health effect, and this trend holds true with DoFasting’s product that only contains 500 milligrams (mg) of ACV.

As our review detailed, apple cider vinegar does have some general health and metabolic benefits, mostly due to its acetic acid content, but the minimally-effective dose used in medical studies appears to be equivalent to around 15,000 mg. The dose in DoFasting’s supplement is 3% of this amount.

DoFasting’s Apple Cider Vinegar Gummies also contains added sugar, which we find to be a very questionable additive for a fasting supplement.

We do not recommend this product, and recommend that patients interested in the health benefits of ACV buy it whole from a grocery store instead.

Conclusion

DoFasting’s program may help consumers lose weight, because intermittent fasting is effective for weight loss, but we don’t believe there is any benefit in paying for their products and services over just tracking hours fasted manually. 

We would recommend that overweight patients seeking to lose weight speak to their doctor about which intermittent fasting program is safe for them, since some forms like alternate day fasting could be a challenge based on current weight and any medical conditions such as diabetes. A doctor’s guidance in regards to individual recommendations would be superior in this regard than an app.

We do recommend intermittent fasting generally to overweight patients (with a doctor’s approval) as it’s proven to be safe and effective on average in medical studies, and is free.

We find that DoFasting’s supplements are poorly formulated, and would recommend a regular fiber supplement without additives over any of the products they sell.
