Most Asked Questions

Why should I FastBlast?

Simply put, it allows you to lose weight quickly in the healthiest way possible. FastBlast provides your digestive system time to rest, allowing your body to use energy for cleansing, rejuvenating and burning fat. You will likely experience an increase in energy, mental clarity, relaxation and joy…and you are sure to lose unwanted pounds.

When is a good time to plan my FastBlast?

You can FastBlast anytime, even while maintaining your usual daily activities. It is a good idea to schedule your first FastBlast when you’re not obligated to attend business or family functions based around meals.

How often should I FastBlast?

We recommend a FastBlast for two days per week until you reach your weight loss goal and then once or twice a week as needed to maintain your ideal weight. Consider a FastBlast at the first sign of a cold or following any sort of overindulging; i.e. holidays, sporting events, etc. Make it a habit, as your body will thank you for it.

How many calories will I consume per day during my FastBlast?

660 calories, based on the recommended six FastBlast pouches per day at 110 calories each. Please keep in mind all calories are not equal. Empty calories from a hamburger and fries are not the same as calories from organic fruits and vegetables. Think nutritional content, not calorie content.

Can diabetics consume FastBlast Smoothies?

With any medical condition, it is highly recommended to consult your physician before starting a diet or exercise program. Each FastBlast Smoothie contains a balanced mixture of carbohydrates, protein, fat and fiber—with no added sugar. Greatly reducing calories can cause a deviation in insulin, so caution is warranted for diabetics. It would be wise to start slower; perhaps just replacing one meal with a FastBlast Smoothie, then for two meals, and work up to a full day and then possibly two days. Again, please check with your physician because blood sugar must be monitored very closely especially, if you are on medication.

I am on a low carbohydrate diet. Can I use FastBlast Smoothies?

FastBlast Smoothies are not intended to be low in carbohydrates as they are very important for maintaining energy. Most low-carb diets limit carbohydrate intake to between 50 to 150 grams per day. Six FastBlast smoothies contain just over 102 total carbs per day, with the majority (84) of simple carbs (from organic fruit and vegetables), which are more easily digested and absorbed into the bloodstream.

Can I take protein powder on my FastBlast?

The ingredients in our FastBlast Smoothies are specifically selected due to their high nutritional content and ease of digestion. Protein takes longer to digest, which is why our formula is not high in protein. If you feel the need to supplement protein (perhaps due to a medical condition), we recommend organic pea, brown rice or hemp protein, taken earlier in the day.

If I feel hungry, can I eat food during my FastBlast?

Your brain is used to you eating all the time, so it is natural for you to feel hungry. But when you think about it, you might find that feeling of hunger is more a “phantom” of memory than actual hunger. We eat to be social and we eat when we’re bored, but for the most part true “hunger” comes about only in extreme circumstances. If you become hungry in between servings, drink a glass of water to help suppress your appetite.

Should I drink water during my FastBlast?

YES! Be sure to drink plenty of water throughout the day. Drinking water can serve as a natural appetite-suppressant by providing a filling sensation in the stomach. Additionally, during the FastBlast your body will be unloading a variety of toxins into your bloodstream and colon. It is very important to help the body flush the toxins by drinking plenty of water.

Can I drink coffee while on my FastBlast?

If you usually consume caffeine, make sure to drink a cup of coffee or green tea to avoid a possible headache from caffeine withdrawal. However, avoid adding cream, sugar or artificial sweeteners to lessen your caloric intake.

Can I drink wine, beer, or any type of alcohol on my FastBlast days?

While alcohol consumption is not encouraged on Blast days (because the body will use the alcohol for energy rather than burning stored fat), most people experience positive results even while drinking an alcoholic beverage or glass of wine on their FastBlast days.

Can I exercise on my FastBlast?

You may want to take it on easy on your first FastBlast but all types of exercise routines are encouraged. There is a common misperception that eating is necessary to supply “energy” to the working body which is just not true. The liver supplies energy via gluconeogenesis. During longer fasting periods, the muscles are also able to use fatty acids directly for energy. As your adrenalin levels will be higher, intermittent fasting is an ideal time to exercise. Pay attention to what your body is telling you and adjust your exercise accordingly while on your FastBlast.

Will I experience any side effects on my FastBlast?

During the FastBlast, the body is burning stored fat, as well as cleaning out all the accumulated toxins that have built up over time—all the while rebuilding cells with new material. FastBlast is specifically designed to allow for gradual elimination and keep your detoxification symptoms to a minimum. However, you may experience some slight symptoms such as headaches, fatigue or rash depending on your current level of toxicity.

What should I eat when I finish my FastBlast?

Most people find they do not have much of an appetite coming off the FastBlast. Consuming small simple meals, the first day after your FastBlast is highly recommended.

What is the difference between FastBlast smoothies and FastBlast Daily?

FastBlast Smoothies are specifically formulated to support Intermittent Fasting while FastBlast Daily is a foundational nutritional supplement. FastBlast Smoothies are used as a replacement for normal daily meals as a method of weight loss and management and can also be used as a healthy snack. FastBlast Daily is designed to help fill the nutritional gaps in your current diet. Think of FastBlast Smoothies as a mini-meal replacement containing a balance of carbohydrates, protein and fat and FastBlast Daily as a super high quality daily nutritional supplement.

Additional Questions

Can I FastBlast while pregnant or nursing?

The FastBlast is not recommended for pregnant or nursing mothers. Pregnant women should not restrict calories as expectant mothers need maximum nutrition. Furthermore, the toxins released into the bloodstream during FastBlast can be harmful to growing babies.

Are there benefits to a one-day FastBlast?

Absolutely! How would you feel if you never had a day off? The benefits of a one-day FastBlast are amazing! Fasting has been used for centuries as a strategy to strengthen the immune system and sharpen mental clarity.

If a two-day FastBlast helps, how about three to five days or longer?

The length of your FastBlast is a personal decision. We recommend two days per week for healthy weight loss as most of the clinical trials on intermittent fasting are based on that timeframe. Each additional day you add is more time for your body to experience the benefits of fat burning and cleansing.

Can I FastBlast if I have diabetes?

With any existing medical condition, such as diabetes, it is highly recommended to consult your physician. Each FastBlast smoothie contains a very balanced mixture of carbohydrates, protein, healthy fat and fiber with no added sugars. However, greatly reducing calories can cause a deviation in insulin, so caution is warranted for diabetics. Again, please check with your physician because blood sugar must be monitored very closely especially if you are on medication.

Can I FastBlast if I am lactose or gluten intolerant?

Certainly! There are no animal products or gluten contained in the FastBlast smoothie.

Can my child FastBlast?

Ideally, it is best to avoid calorie restriction while children are growing. However, with childhood obesity at an all-time high, it can be considered on a case-by-case basis. We recommend that you consult with your child’s physician.

Can I have seltzer or sparkling water? How about sodas or other drinks?

Seltzer or sparkling water is not ideal because it will contribute gas to your system. However, it’s not a bad option if it will keep you from drinking other beverages. Drinking sodas is not recommended on your FastBlast. Sodas are filled with sugar and other undesirable chemicals and are very acidifying. Try to drink water with lemon or herbal or green tea instead.

Will I get light-headed if I’m not eating solid food?

It’s possible that a mild light-headedness or headache could occur at some point during your FastBlast. However, many people find that they do not experience this at all. All the energy usually taken up by the digestive process will be available for restoration and rejuvenation. Usually one’s mind becomes clearer and one's ability to solve problems increases.

Will I burn muscle while on my FastBlast?

On your FastBlast the body first breaks down glycogen into glucose for energy. After that, the body increases fat breakdown to provide energy. Therefore, the body will not burn muscle during your FastBlast.

I haven’t gone to the bathroom at all, and I’m on day two. Is that normal?

Reduced input means reduced output. This is completely normal.
