I would like it a whole lot more if they just added a feature to save my meal. If I make a meal that meets the requirements and I enter it, I want to be able to save that meal so that I don't have to enter it item by item every single time I eat that meal. If I could save a meal bank for each phase that I could then go in and click if I was going ti eat that again and it would automatically check all the boxes for chicken, brown rice, tomatoes, etc, I would be super happy and give it 5 stars. As it is, I am just slightly annoyed and give it three. ETA: I also wish it had a graph that tracked weight. ### 3/5 — I Would Like This A Lot More If... *2025-07-14* I like the app. It is a little clunky but it works. I would like it a whole lot more if they just added a feature to save my meal.

I was overweight and my husband was dangerously overweight with type two and other maladies exacerbated by the poor way that he ate. I've had to be more careful about things I ate due to Crohn's and a stenosis in the gut where they removed a portion and put me back together. But we were both in need. I showed him the article which I probably found in a woman's day magazine. I was shocked when he told me he believes he could do this. Together we lost a ton of weight. Life happened and we derailed due to family death and sale of home and a huge move which caused less time to cook and pay attention to our bodies. I lost my hubby in May, I continued to lose weight but I've put on about eight pesky pounds and I need to eat better so I'm starting this again. I can't say ENOUGH about the energy we had during the months that we followed this plan. From the bottom of my heart I thank you. It's simple to follow and though there are a couple days where your mind thinks you're depriving yourself, the other five days make up for it. If you want to lose it, this IS the key. Tricking your metabolism. Don't go your whole life feeling miserable and not liking how you look like in the mirror. I was old when I started this. I regret not learning about it years ago. This is it and it was inexpensive. You feel a difference from week one and it only gets better. Highly recommend!! ### 4/5 — More foods *2025-01-27, version 2.21.11* I’ll being using this app since 2016, and still there are some some fruits, veggies and other things that are not included, and it is a little frustrating because I want to consume them but I don’t know under which phase put them. ### 4/5 — Update app *2025-01-04, version 2.21.11* Please update the app. It’s slow and it doesn’t seem to work right away when you click on a button. ### 5/5 — Amazing *2024-06-29, version 2.21.11* We love this ap! So easy to keep track of your foods and times you eat, it’s my favorite! ### 3/5 — Needs update! *2024-05-16, version 2.21.11* I have been doing this diet plan for years and the app looks the same as it did when I purchased it over 5years ago. The investment users are making into books, shakes etc the least that could be done is a more modern and updated app.! ### 4/5 — App Issues *2023-05-18, version 2.21.11* I like the diet and app, but two things. First, the app has been opening to yesterday rather than today, and it has been doing that since I restarted the diet. (I don’t know if this makes a difference, but I traveled across two time zones when starting this time). Second, the Phase 3 breakfast meal “B and B Toast” wrongly populates as having a protein (it doesn't) and leaves the fruit section empty despite the recipe including berries Other than these glitches, the app is always helpful to doing the diet ### 4/5 — Simple app but it works! *2023-04-17, version 2.21.11* I’m writing this review as it is the 10 year anniversary of the Fast Metabolism Diet book. I preordered the first edition and did a few rounds of the diet the past 10 years. I want to say that the diet works and this App, although not perfect, is a great tool at your fingertips. I put on Covid-Menopause weight and although I have not re-read the book entirely, I’ve been on this diet non-stop for the past 7.5 months just following the app prompts, and have lost 40+ lbs so far. I praise this diet to anyone who wants to hear how I did it. The app does need an update, but it works nonetheless. ### 2/5 — This app is useless except for planning *2023-02-26, version 2.21.11* My husband and I are doing this diet. We read the book. We downloaded the app to facilitate things. We’ve been very frustrated with it. Really, all it’s good for is meal planning, and that is absolutely it, and even if that’s all you’re using it for you’ll be frustrated. Pros: water tracker, planning times/foods for meals. Cons: 1) You’re not really “tracking” your food if you can’t enter everything that you eat, even if it’s something that’s not supposed to be there. There should be some way of entering foods that are either off-limits or out of phase. (Side note: I’m pretty sure you can email your data to the company so they can analyze what you’re eating…what good is that when you cannot truly track things?) 2) In that same vein, it doesn’t let you track your portions. That’s fine if you’re someone trying to lose 20 pounds or less (1 portion), but as she says in the book, if you’re trying to lose more than that, you will need to increase your portion sizes. Well…you can’t track portion sizes here. I have many more gripes with it but those are the biggest. I do think this is a good way of eating so far, so I give the diet a hesitant thumbs up (only in week one) but this app needs some work. ## Frequently asked questions about The Fast Metabolism Diet ### What is the Fast Metabolism Diet App?
