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!
I love the app , but…….
MRecovering
I decided to try this advertised app a couple of weeks before I was having a big orthopedic surgery of a total ankle replacement . Probably not the best time to start but it has helped me to lose a few lbs before surgery and now that I’m 2 weeks post op I pretty much maintained my loss. I couldn’t weigh myself for 2 weeks because I had a heavy cast on and now it’s even difficult as I can not bear weight on my left foot , so I’m weighing in on 1 foot. The app has a few glitches for my situation . I tell Avo ( my AI coach) that I can’t weigh in because of the situation and I’m always prompted to do it anyway after she tells me it’s ok. The app also tells me often that I’m eating either too much or the wrong foods for weight loss. I didn’t want to starve while preparing for my surgery and I want to eat well while recovering so if it takes me a bit longer to reach my goal, it’s ok with me and should be with this app. It sometimes records a meal that I had the previous day and I don’t know if I did something wrong or that app glitched. There are other little glitches and for the most part Avo is very supportive , with the ovation of the little purple guy basically scolding me when I eat a bit more even though it all healthy foods for my recovery . I’m looking forward to being able to use the app properly when I can bear weight on my foot in a few months . I’m not sure if I should cancel until I can do the walking portion properly . 😊

It doesn’t feel like I’ve changed anything in my life except time. When I eat is grouped into another time frame and in my non eating time I am sleeping or working or running errands. Some days are busier then others so my fast may go to 20 or 24 hours on busier days . My working time is 12 hour nights in an ICU . I am learning to start my fast 4 hours sooner on my three work nights… so 4 p to 4 a. Its been about 34 days on this fasting ride and I feel like it’s already a permanent change in my life that I want to keep. At 63 Simple has taught me a new way of being with my relationship to food work and play. I feel the Best when I’m in the 18/6 fasting…less knee ache, no belly issues, sleep better.. love the fasting stopwatch on face of my phone.. each time I pick up my phone I’m reminded I’m in this competing with myself. I’ve learned to add a stool softener with my last meal so during the 18 hours fasting I’m not worrying about if when and where ….. just adds to the feel I’m more in charge of my life… and I like that. I’m down 14 to 18 lbs in this 34 days on Simple. I would like to lose 60 total. I take a pic with each daily weight in the same spot/chair/background. Its a pic of me from neck up and within first 10 pounds I saw weight loss in my nose and now there is a wrinkle in my forehead?! Yesterday I reached over my left shoulder to scratch and it felt like more bone then fat? Even if scale doesn’t say it I am seeing and “ feeling” it….. everyday.
From a very appreciative participant
Love SLP
I have had type 2 diabetes, (aka metabolic syndrome) for about 25 years. During that time I gained much weight, and struggled to keep my blood glucose levels in check. I had worsening insulin resistance and was eventually on the maximum dose of metformin, to no avail. My doctor additionally put me on insulin, and over time I had to increase the dose to counteract my still-high blood glucose levels. I felt doomed and helpless. I started to make necessary lifestyle changes to improve my condition; not an easy thing to do, but I knew I must. For several months I worked hard and I saw slow improvement, but I stayed hopeful. I was searching online for things that might help me on my journey. I came across the Simple Life Plan and thought it looked like something I should try. My life hasn’t been the same since, in the best possibly way, that is!!! Simply Life Plan has been so informative about nutrition, exercise, and the benefits of fasting. So far I have lost 22 pounds and am completely off all my meds!!! Coach Avo has been there all along the way advising, supporting and encouraging me on my journey back to good health. The app also has so much information on nutrition, as well as recipes to try. There are even exercise routines to follow. I would recommend Simple Life Plan to anyone who is working to improve their health and fitness. Simply Life Plan will truly make your journey a simple and effective one! Thank you so much for creating the Simple Life Plan!!!
