Science has amply proven that intermittent fasting is safe and effective. Hence the current success of this powerful tool against excess weight which destroys damaged cells and reduces inflammation in the body. *** VISIT OUR WEBSITE TO SEE ALL OUR APPS Weight Loss, Intermittent Fasting, Keto, Sports Nutrition, Diabetes, Nash, Oncology, Cardiology, Epilepsy *** There are three important points that make intermittent fasting a great tool for permanent weight loss as well as improving your health. Too many people ignore them and fall back into the Yo-Yo effect once they stop intermittent fasting. 1. ALLOW YOUR METABOLISM TIME TO GET USED TO INTERMITTENT FASTING ● First get your body used to switching to lipolysis (breakdown of body fat to energy) ● Then get it used to switch to autophagy (consumption of damaged cells). ● DietSensor will help you gradually start intermittent fasting with the 14/10 pattern (14h of fasting followed by 10h during which you will have 2 meals) and progress to longer fasts like the popular 16/8 pattern (16h of fasting) or more, up to 23/1 with one meal a day. 2. PROLONG THE GOOD EFFECTS OF FASTING DURING THE NON-FASTING PHASE ● Make healthy food choices, which you will keep all your life, for lasting weight loss. ● If desired, you can increase the effectiveness of fasting by following a ketogenic diet to maintain fat consumption. ● Unlike light, bland and boring diets, you can eat natural, tasty and nutritious foods that you like such as meat, eggs, cheese or even chocolate. ● DietSensor will help you make meals that limit the levels of insulin (the fat storage hormone) after meals 3. DON'T MAKE THE MISTAKE MANY DIETS ADVOCATE ● Drastically restricting calories and exercising more to lose weight has been shown to fail in the long run. 80% of your progress will come from your food choices. Exercise will be optional! ● You will have to make meals compatible with your long-term lifestyle: without cooking if you want. This must be done without unsustainable deprivation over time and without starving yourself. Occasional deviations are not only allowed but mandatory with DietSensor. ● You will have indications on food quantities to give you every chance for your metabolism to act efficiently and durably towards the weight you are aiming for. DIETSENSOR IF (INTERMITTENT FASTING) IS A COMPLETE AND CONFIGURABLE TOOL ● Set up Calorie, Net Carb, Fat and Protein percentages as well as macronutrient goals per meal ● Database of more than 1M foods with barcode and voice dictation, macro tracking ● Glucose/insulin impact curve for each meal ● Smart Meal Generator, Recipes, Menus and Shopping Lists ● Expert articles on intermittent fasting and diet ● Daily tasks, reminders, motivational messages, analytics and chats with our dieticians 7 days a week ● Tracking of steps, physical activities and water HEALTH APP ● Connect the Apple Health app and import your weight and exercise automatically. Export your meals REWARD ● Voted the most innovative App in the world at CES 2016 ● Second place in the Publicis90 global innovation competition PRICES & TERMS OF USE To use the application, you will need to subscribe to one of the PREMIUM packages.
