About this app

Intermittent Fasting 16:8 will guide you to a new lifestyle with healthy habits. You’ll lose weight effectively and feel more active! No diet and no yo-yo effect.

IS IT EFFECTIVE?
It’s proven that intermittent fasting leads to fast weight loss. During fasting, as your glycogen depletes, your body switches to ketosis, which is referred to as the body's "fat-burning" mode. This is an effective way to burn fat.

IS IT SAFE?
Yes. It’s the most natural and safe way to lose weight. Studies show that eating all the time makes your body unable to take a break from digesting, which can result in health problems, such as diabetes. When you fast, you just take a break from eating, it takes some of the load off your liver.

CAN I USE FASTING TRACKER?
With various fasting plans, fasting tracker is suitable for beginner and experienced, men and women. It guides you through your plan. No need to change your diet, you can easily stick to it. If you are under 18 years old, pregnant or breastfeeding, have health issues or are underweight, please ask your doctor for advice before fasting.

SCIENTIFICALLY PROVEN INTERMITTENT FASTING

Effectively Lose Weight
Your body switches into fat burning mode. You’ll burn body fat reserves and prevent food you eat from being stored as fat.

Natural and Healthy
When fasting, your body will actively burn fat, get into detox mode and start the process of regeneration.

Detox
Your body reduces inflammation. Cells break down viruses, bacteria and damaged components.

Prevent Diseases
Studies show that fasting can prevent numerous diseases, such as heart diseases, diabetes and cancer.

Cell Repair and Regenerate

Against Aging
Your body initiates autophagy, a process of detoxification, repair and regeneration. This has benefits against aging.

Love this app as it gives a lot of info even in the free version. But has something changed with the fasting start time? I'm sure I used to be able to change the start time once fasting as sometimes I put in the wrong time but it doesn't allow me to edit it anymore. Would be helpful if this was still an option. Also, full page ads not always closing down. I normally close the whole app, wait 10 minutes and, if I remember, go back in and it goes straight to the home page.

Hi, thanks for your love! In daily plans, you can click Start✏️ to edit the fasting start time. In weekly plans, you can click Edit to modify the time. You may also send relevant screenshots via Me>Settings>Feedback for more help. Regarding ads that cannot be closed, could you send the relevant recordings and ad links? We will continually optimize.

This is a great app except for one thing. When I start a fast in the morning, I actually started last night when I finished dinner. But you can't edit your fasting time, it starts from zero when you click 'start fast'. You can edit it at the end, but it's not very motivating when your time is 12 hours less than your actual time. On short fasts, not really worth worrying about, but I do long term fasts.

Hi, which plan are you using? In the daily plan, you can click the pencil icon next to Start on the Fasting page to edit the start time. In the weekly plan, to give users enough rest time, the timer will only run after you start the plan. If you have questions, you may send us relevant screenshots via Me>Settings>Feedback and we'll help you.

Good free functionality, but crammed full of intrusive ads. ||| Update after a year of paid use: Now they introduced challenges that keep popping up and nagging me to join almost every day. These are the last straw for me using the app. Sadly it's still the best fasting tracker if you prefer phone apps, but I'll just switch to a trusty spreadsheet. Now if only the app let me export my fasting history into .csv...
