GOT A QUESTION? GIVE US A SHOUT AT HELLO@BURNBOX.HEALTH OR FIND SOME ANSWERS BELOW.

Will I feel hungry?

Don't sweat it! We've got a delicious strawberry-flavor fiber drink that will keep you feeling full without messing up your fast because it’s practically zero calories.

Will I feel tired?

Actually, most folks find they get a nice energy boost during fasting because your body doesn't have to deal with digesting food. Plus, we'll show you what to do before your fast so your body has plenty of energy in the reserves to weather the fast.

Will I get 'keto flu'? (headaches, dizziness, nausea)

Don't stress! We'll show you how to avoid common mistakes that lead to keto flu. Stick to it, and you won't have to deal with those nasty symptoms.

What if I mess up my fast and don't have enough fiber drink left to start all over again?

No worries! You can easily order a refill. Or you'll get a refill automatically with our 6-month or 12-month plans (just have to wait a bit). That said, you can also fast without a fiber shake – it's totally doable and many of our customers love the challenge.

I'm not sure I have time to fast. What about dinners with friends and birthdays?

Totally get it! We suggest planning your fast for a long weekend or during a holiday when you have more freedom in your schedule. Sure, it might be a bit inconvenient, but remember, it's your health we're talking about here – maybe it's worth the effort?

Is fasting safe?

Generally, yes, but it depends. If you've got diabetes, you should chat with your doctor first since it can mess with your blood sugar. For those who are pregnant or breastfeeding, it's usually a no-go because your body needs extra food for the little one. Best to check with a healthcare pro to be sure fasting's cool for you!

How's Burnbox different from other fasting methods (like intermittent fasting and fasting-mimicking)?

A 3-day fast like Burnbox can be more straightforward and impactful than fasting-mimicking or intermittent fasting. Here's why:

Simplicity: With a 3-day fast, you have a clear start and end. There's no need to constantly plan meals or watch the clock for eating windows, which you often have to do with fasting-mimicking or intermittent fasting.

Intensity and Results: A full 3-day fast can kickstart significant metabolic changes in a short period. It's like a hard reset for your system, potentially leading to more noticeable results compared to the gradual approach of intermittent fasting or the partial fasting of fasting-mimicking plans.

Mental Clarity: Some people find the absolute nature of a 3-day fast easier to stick to mentally. There's less room for bending rules, which can happen with intermittent fasting (like overeating in eating windows).

What’s in your fiber drink?

Glucomannan is the key ingredient, it absorbs water and keeps you full during your fast, which helps with hunger pangs. Plus, it's only 10 calories, so it won't mess up your fast.

What happens after I pay?

Your Burnbox is going to be dispatched within 3–5 business days. There, you will find everything you need to make the most of your experience and achieve your goals.

Is Burnbox safe?

The Burnbox program is meant to support general health. Use it as part of a healthy lifestyle. If at any point you feel unwell, please consult a qualified healthcare professional.

What's the difference between the Burnbox, intermittent fasting, and fasting-mimicking plans?

Your Burnbox is a 3-day fasting kit combining functional modern supplements and ancient wisdom principles to boost your weight loss.

Fasting-mimicking plans stimulate your body's fasting state while allowing you to eat restricted calories. You still have to plan your meals. Also, people often experience painful side effects when transitioning back into their routines after fasting.

Intermittent fasting limits the hours when you are allowed to eat. People often struggle with binge eating, building new habits, and incorporating them into their routines.

Why should I get a yearly supply of Burnbox?

By consistently following the Burnbox program throughout the year, you'll fast-track your weight management journey. After each box, your metabolism remains efficient in metabolising fat at an accelerated rate.

The yearly supply consists of 4 boxes, aligning with our recommendation of fasting no more than once every 3 months for optimal results.
