Can this concept be used easily? How do you count calories anyway? The Secret of Weight gives you all the answers! How many calories are you entitled to each day? What happens if you go overboard? Find out with this app! The best feature of all, however, is that this app makes calorie counting a breeze thanks to the photo-based food choices to select from! How does it work? - Each day, you work with a set Calorie Budget that you can “spend” on your food choices, not matter what they are, without gaining any weight. You therefore work with a set number of Calories each day, which means you can “spend this budget” on any type of food you like! There are no food restrictions, the point being that as long as you stick to your budget, you will not gain weight! This is the real Secret of Weight! Okay, so how does it all work? - Each time you eat something, look it up in the photo database and add that item to your cart for the day. A bar gauge on the side of the Dashboard shows how many Calories you have left for that day. - If you go over budget, you start gaining weight. The equivalent amount of weight gained is displayed on your app in real time, based on how many extra Calories you have consumed. - If you stay under budget, you start losing weight. The equivalent amount of weight lost is displayed on your app in real time, based on how many less Calories you have consumed. This new concept is based on the idea that there are no forbidden foods, even when you want to lose weight! You will also find out how high or low your calorie intake should be to gain or lose a few pounds. You can download and use The Secret of Weight app for free.
