What’s the best way to lose weight? Should you reduce the total number of calories in your diet or lower the total glycemic load? There is scientific evidence to support both approaches, so which one should you follow? Well, it turns out that both are important! Everyone knows that calories are important, but not everyone knows that when you eat those calories you can do three things with them: burn them for energy; store them as fat; or use them to build lean body mass. What you do with those calories is determined by hormones in your body, the most important being insulin. Your insulin level is determined not only by the number of calories you eat, but also by the type of calories you eat. This is why what you eat (glycemic load) is as important as how much you eat (calories)! The Low-Glycal Diet™ app by BioFit uses both glycemic load and calories to calculate the number of “glycals” in a meal, which is a better predictor of how fattening that meal will be. The “glycal” is calculated from a formula developed by Dr. Jeffrey S. Dunham, M.D., Ph.D., M.P.H., medical director of BioFit Medical Group and graduate of Harvard Medical School, and is based on the latest medical research. The total number of glycals in a meal equals the total number of calories in a meal that will be stored as fat. The Low-Glycal Diet™ app by BioFit contains over 1000 easy-to-find foods which are color coded as green (low-glycal), yellow (medium-glycal), or red (high-glycal) if eaten alone. You assemble a meal by choosing the individual foods in that meal. The app then calculates the total number of glycals in that meal and gives you a green, yellow or red result. The number of glycals will change depending on how you pair foods together. For example, eating two fried eggs (a green food) with two slices of cheddar cheese (a green food) will give you a green meal, but eating two fried eggs with two slices of dry whole wheat toast (a green food) will give you a red meal. The ranges of green, yellow and red also change depending on when you have the meal, since eating carbohydrates after 6PM can be more fattening than eating them in earlier in the day. You never have to be hungry on The Low-Glycal Diet™ by BioFit. You can have all the green meals you want in a day, as long as they are separated by two hours. You’re allowed one yellow meal a day and one red meal a week. The fat loss is almost effortless, so start losing fat today!

It was a convenient way to login my food, never be hungry and keep my insulin spikes in check. ### 3/5 — Missing some functions *2025-07-12, version 2.3* The app has many glitches, including that an error message occurs when you try to pay for the pro version of the app. In addition, any of the “info” buttons within the app bring up a blank webpage ### 5/5 — Great app! *2025-04-20, version 2.3* This app has been helpful to me for YEARS!! ### 5/5 — Great Way To Lose Weight *2025-02-14, version 2.3* Losing weight can be a difficult journey. There are tons of books and approaches out there - most contradictory and confusing. The Low Glycal Diet is a simple approach that will work for anyone. The basic rule is don’t combine protein/fat meals with carbs! If you use the app and follow Dr. Dunham’s book, the pounds melt off. Really! I don’t think there is a better method for reaching your target weight and keeping the excess pounds off indefinitely. This is a wonderful and effective diet. No points to count, no exercise routines, & no pills to take, etc. The Low Glycal Diet is truly a lifestyle plan that is a joy to follow for the rest of our lives! ### 5/5 — invaluable *2024-09-16, version 2.3* I’ve used this app regularly for years. It is excellent. there are no other apps like it. I hope Biofit will continue to support it. ### 1/5 — Diet Didn’t Work *2024-01-13, version 2.3* The plan didn’t work for me and I followed it to the letter. I live near the Doctors Clinic, so I called for advice, and even offered to pay for a consult but didn’t even get a call back. This leads me to believe that he’s “selling snake oil”. The app says calories don’t matter. Really?! I wanted to believe it and his book sounded logical but it didn’t work. ### 1/5 — Wish I never paid for this app *2023-04-08, version 2.3* The only thing this app does is aggravate me. Now matter what kind of food combos I put in, it’s red and leaves no reason why. There are no planned meals for suggestions and the info tab does not work. NOT GOOD ### 4/5 — Needs ability to manually add food items *2022-12-31, version 2.3* The app is great, but it’s not really a solution without the ability to manually add items. If I know the calories and GL for a food, I can calculate glycals on my own- but then I can’t enter the meal into the tracker. If I could enter glycals myself- or even better, enter calories and GL and have the app calculate it for me- this app would be an all in one solution for following the diet. As it is, I’m having to keep a notebook, and the “pro” features that I paid for are t much use to me. ### 1/5 — Dead App - I purchased it a few years back - received no support. *2022-09-13, version 2.3* Dead App - I purchased it a few years back - received no support. ### 2/5 — This would be great but…… *2022-07-04, version 2.3* I purchased the Pro version and entered my breakfast this morning and the time states it’s 10.20pm. I can’t find anywhere in the settings to change my location to GMT. I tried sending a question to be answered but it hasn’t sent. Also I have raw food supplements daily and I can’t search for this. Most other apps I’ve used you can scan a bar code to find the food. Disappointing. ## Frequently asked questions about The Low ### What is the Low-Glycal Diet app?
