Products & Services By DoFasting

The DoFasting app plays several roles in your intermittent fasting plan. Not only does it offer diet recommendations, but it also offers basic workout routines and ties your eating windows and fasting routine. 

All DoFasting supplements act as an appetite suppressant to help you gain your desired weight faster and prevent certain health conditions in the process. The supplements in question provide nutrients and vitamins in addition to boosting your body’s fat-burning processes. 

These supplements nourish your gut bacteria, decrease cholesterol levels, and offer that much-needed energy boost when taken daily. Keep reading to find out what each supplement has to offer: Take note that all these supplements are packed in supplies that should last at least 30 days: 

DoFasting Appetite Suppressant

The DoFasting Appetite Suppressant is Fasting Solutions UAB’s flagship supplement. It’s an appetite suppressant that triggers a sense of satiety, thus allowing you to extend your fast and stay in control of your hunger pangs. The DoFasting Appetite Suppressant also regulates your body’s cholesterol and keeps your colon healthy.

The supplement also contains soluble fiber in the form of glucomannan. The fiber helps to expand your stomach and gives you a feeling of fullness.

The DoFasting Appetite Suppressant also contains glucomannan and cellulose. There’s no trace of calories and other similar ingredients that might interfere with your intermittent fasting. It is also vegan, gluten-free, non-GMO, and available in orange and strawberry flavors.

When we tested the DoFasting supplement, we noticed that it’s super effective in terms of hunger suppression. This was the case even in our final hours when the struggle became the strongest. Despite this, plenty of other fiber-based supplements with a similar fiber-based background will carry out a similar function at a lower cost.

How Does the DoFasting Appetite Suppressant Work? 

DoFasting Appetite Suppressant supplement contains two main ingredients: cellulose (undisclosed amount) )and glucomannan (approx. 2,000mg).  Cellulose might be effective[1] in managing weight loss. It also has protective effects against constipation and other chronic diseases. 

Research[2] has shown that glucomannan is an effective weight loss ingredient. It promotes a sense of fullness and lowers energy absorption from proteins, carbohydrates, and fats.

Fibers such as glucomannan and cellulose are bound to trigger symptoms[3] such as potential hypoglycemia, diarrhea, bloating, and gas.

DoFasting Smart Scales

The scales are compatible with the DoFasting app. All information gathered by scales is portrayed on the application. This way the application gets even more weight, and the user can flawlessly track his/her metrics: 

  • Ideal Weight – Ideal body weight is the optimal weight associated with maximum health and life expectancy for a given height, age, and gender.
  • Body Mass Index
  • Basal Metabolic Rate – the minimum amount of calories needed for the human body to function and perform vital functions. It is the number of calories required to keep your body functioning at rest. About Basal Metabolic Rate – body’s metabolism; therefore, any increase in metabolic weight, such as exercise, will increase BMR.
  • Body Fat (%) – the percentage shows the total mass of fat divided by total body mass. Body fat includes essential body fat and stored body fat. An average healthy body fat range should be 22–32% for women and 10–22% for men.
  • Skeletal Muscle Mass (%) – it estimates the weight of muscle in a person’s body. Muscles maintain the posture, enable the heart and internal organs to function, produce energy to maintain body temperature, and drive activity.
  • Bone Mass – the predicted weight of bone minerals in the body. While bone mass is unlikely to undergo noticeable changes in the short term, it is important to maintain healthy bones by having a balanced diet rich in calcium and increasing physical activity. Track the bone mass measurement over time and look for any long-term changes. 
  • Water – the percentage of total weight that consists of water. Our bodies comprise 40–70% of water, and even slight changes in fluid balance can lead to drastic changes in performance and overall health. It is important to understand the individual’s hydration baseline and monitor it closely to avoid dehydration.
  • Protein Mass (%) – tracks the amount of protein in the body. Proteins are essential for bodily functions, growth, and maintenance. Aside from water, proteins are the most important kind of molecule in the body. 
  • Body Type – based on muscle structure and body fat levels. As activity level changes, the balance of body fat and muscle mass can gradually alter, which in turn might affect a person’s overall body type. 
  • Metabolic Age – depends on the activity level, genetics, height, weight, and actual age.

Is DoFasting Legit?

Yes, it is. DoFasting has a calorie tracker that lets you input your daily meals, and it will give you a brief breakdown of your macronutrient and calorie consumption. 

The water tracker works just fine. You can use the DoFasting app to determine how much water you’ve had in a day and how much more to go before reaching your daily target. Overall, DoFasting is a pretty decent app that can help you keep track of your weight loss journey as well as your daily calorie intake. 

If you need support and connection in the course of your journey, head on to their online private group on Facebook. The group has over 47,000 members with whom you can share your personal fasting experiences, your wins, and so on. 

Also, their customer support team makes nutritionists and supportive specialists available at all times: via email at [email protected] or via live chat built on the mobile application.

DoFasting App Review: What Do Real Users Say?

“I’ve found the DoFasting app relatively easy to use and quite helpful in my efforts to lose weight.”


“It took some time to get going, but now I’m losing the weight. You just have to be patient and make the lifestyle change. This is definitely not a quick-fix.”


“I had trouble keeping up with the app’s water target. It was kind of unrealistic, in my opinion. That aside, I enjoyed the 12-hour fast. Good work, guys!”


“For first-time users, it might take some time before you get the hang of things”


“Don’t waste your money on this crap. You can successfully complete your fasting program even without this app.”

Final Thought

This intermittent fasting app is helpful for individuals with over-eating disorders or those on a personal fasting plan. It’s one of the few fitness apps that offers meal suggestions, reasonable workouts, and a health tracking feature. 

On the other hand, this program may not be worth your buck for a couple of reasons. DoFasting has a controversial past. There are free intermittent apps on the google play store that also offer intermittent fasting services. If you’re still intent on using this app or its supplements, we suggest you seek your doctor’s counsel before taking the next step.
