FastMe - YOUR PROFESSIONAL FASTING ASSISTANT WHY CHOOSE FASTING? The most natural way to lose weight and keep fit. Improve your body and brain function. Burn your body fat reserves. Boost your growth hormone. Lose weight without diet and exercise. Make you feel more active. No need to count calories intake. FEATURES OF FASTING TRACKER - Intermittent fasting tracker - Weight monitoring - Notifications about start/end of fasting and food window - Detailed analytics - Most popular 16/8 scheme and more - Fasting schedule - Weight sync with Apple Health IS IT EFFECTIVE? It’s proven that this healthy lifestyle leads to fast weight loss. During fasting, as your glycogen depletes, your body switches to ketosis, which is referred to as the body's "fat-burning" mode. This is an effective way to burn fat. IS IT SAFE? Yes. It’s the most natural and safe way to lose weight. Studies show that eating all the time makes your body unable to take a break from digesting. When you fast, you just take a break from eating, it takes some of the load off your liver. CAN I USE FASTING TRACKER? With various fasting plans, fasting tracker is suitable for beginner and experienced, men and women. It guides you through your plan. No need to change your diet, you can easily stick to it.
