What is intermittent fasting?

Intermittent fasting is an eating pattern that has significant health benefits. It can help you lose weight and keep it off long term. All without calorie counting or banning any of your favorite foods. 
No matter what you’ve heard, intermittent fasting doesn’t have to be hardcore. Even short fasting schedules, (like 14/10, for instance, where you fast for 14 hours and eat over 10) can burn fat and boost your energy and zest for life. 
It’s not a fad. It’s been around for a long time. Intermittent fasting is a safe, effective way to reach your weight loss and health goals. Best of all, you can choose the eating schedule that best suits you and your life!

Turned my life Around

I’ve been struggling with weight loss and getting in shape for my entire life. I’d lose weight and gain weight all the time. Less than two years ago I was 240 and I got to 300 and I knew I needed to change but I didn’t know where to start. I downloaded Simple because why not after I got an ad for it and it helped so much. I rarely write reviews for apps or anything but I just want to say thank you. I’ve lost 10 Pounds in the last month. For the first 3-4 weeks, I struggled with building my habits so I didn’t lose as much as I may have wanted but I’ll get there. I’m eating a lot more nutritious foods, have cut out food after 9 PM completely through willpower and convincing myself to not do so, have learned more about how to stay full and motivating myself, am now drinking about a gallon of water a day and that’s amazing, and I’m exercising almost every day getting cardio in paired with the Fitbit I have. All of this is because I recorded this stuff down. And ITS FREE. You don’t need the premium which is the best part. Just to log ur weight, what you eat, when you drink, when you exercise (don’t even need to if you pair a Fitbit), makes a huge difference. Pair that with motivation to do intermittent fasting and I’ve lost 8 pounds in the last week and a half. I’m gonna keep going and I’ll come back to this review and update my progress every 10 pounds. I’m at 290 right now

Was more motivating before

Hi makers of Simple!
I wanted to share with you that this app was very helpful the first year that I used it. It was the only way for me to lose weight and when I travelled with a group for half a year, I was the only one who could maintain my weight and I felt super proud of that! I renewed my subscription but then 2 months later I got pregnant, so basically I couldn’t fast anymore. I changed it in the settings, that I was pregnant, but that didn’t do anything to the app. No recommendations or anything. I did some very light fasts by myself now and then for health reasons but I basically didn’t use the app for the rest of the year. I did renew the subscription because I was exited to lose the baby weight. But I see the option to say you are pregnant or breastfeeding has disappeared. I know some don’t recommend to do it while nursing but actually a lot of people do light fasting and have a lot of benefits from it without it affecting their milk! But I also see that the interface has changed… I really liked the visual circle of time tracking. It was very encouraging and motivating. Now it’s just a line that doesn’t move… I also liked clicking on pictures of what kind of food you ate and the effect it gave on what articles you get. This disappeared too. Just typing it… but then I don’t feel it does anything for you. I don’t know… I feel it's not as engaging anymore. But I still want to five it 4 stars because the app has helped me so much before!

Things I never imagined

I started this on a whim after seeing a social media post of a friend who had decided to try intermittent fasting. Then I saw an ad for simple. I decided to try your app then had serious second thoughts and canceled before I even started. A few days later I decided to use it for the period of time I had already paid for so I wouldn’t feel like I totally wasted that money.
Wow! I went all in and with Gods Grace was able to really take advantage of all the information the app provided. The weight started coming off quick. I was impressed. But what I found with those nutritional changes was a new lease on life. I had gone through breast cancer recently and didn’t feel like myself, had really given up on ever feeling normal again. I thought the medication was making me feel the way I did, I was taking ibuprofen by the hands full for body pain. After starting this fasting and mindful eating the inflammation left my body (in3weeks!) and I no longer need to take anything for pain. My pain level is 95% less now at least, just the old age stuff left now (I’m soon to be 55). To date I have lost 42lbs. I started this on 1/6/23
It’s worth every penny, the information provided is priceless. I am so thankful for this app and God for giving me push to continue what I started and prayed for.
