Full Featured App With Nice User Interface

I’ve been on a calorie restricted diet for years making very slow progress on my weight loss goal. I decided to start recording the time of my last food each day knowing that the time you eat may be as important as how much you eat. It quickly became a burden and a clutter on my calendar so I went looking for an intermittent fasting app. Since my original interest was just recording the time of my last meal I wanted a simple low/no cost app. I found only one free app that didn’t have in-app purchases to goof up features. Zero was that app plus it had the bonus of a 4.9 rating. To my surprise this is a full featured app with a very high quality UI . It has historical tracking of your fasts and can read or write to Apple Health. The app had so much IF learning information that I began a 16:8 schedule. I’m only on day 4 but my progress has improved while keeping exactly the same calorie goal. No matter what your needs to track IF or TRF you are in for a treat with a professional app to assist you.

Used this app to lose almost 70 lbs in 3 months

Then the pandemic happened and I stress ate my way through. Now there’s a vaccine coming and I want to get back on track again. I highly recommend this app for weight loss, health, energy, anti-aging, etc. I wish I’d known YEARS AGO that fasting was healthy and a real way to stay healthy and fit. We were lied to fir decades, but it’s not too late to take control of our bodies and health!

I tried a lot of apps for fasting and this is the most flexible. You can edit your start time after starting the fast so if you forgot to start the app, but remembered to fast, you’re all set. It has some scheduled routines and a lot of freestyle, so lets you do you. Notifications are inspiring as it shows how many other people are fasting. You can eat a wider variety of foods if you fast regularly with far less negative impact on your weight and health. I don’t feel like a failure or dread coming back to this. I got anew iPhone and it triggered me to get going again. I’m really excited! Join me in a fast today!

Should have tried this sooner

I’m 47. I was about 40 pounds overweight, five days ago. Now I’m only 30 pounds overweight. I’ve alternated between the 16:8 and 18:6 fasts and been a diet Nazi on myself. I’ve switched to a Mediterranean diet, and probably eat between 1,000 and 1,500 calories a day (I don’t keep an exact count, and that’s just a rough estimate.) Basically, I’m eating about half of what I normally do in food, and have cut out all alcohol and nighttime snacking. Have tried to walk/jog about a half mile a day and run around the yard more with my 5-year-old. I imagine if I exercise harder, I’ll turbo boost this process even more. On a scale of 1-10, my hunger pangs while fasting have sometimes hit about a 5. But it’s totally manageable and takes just a little bit of discipline. With this app’s countdown timer, it’s easier to hang in for the last hour or two, because the end is in sight. And when you do eat, you want to eat as healthy as possible so you don’t feel like the fast was for nothing.
My beer belly’s days are numbered.
