Calories go in two directions. As long as we eat more than we eat, we can lose weight. From my experience of losing weight, there are two apps worth trying. By the way, use the steps.
Know your calorie consumption, which is the consumption of not exercising every day. This has something to do with our age, weight, gender and so on. This can be measured by mint app.
It can give a relatively accurate feedback by inputting the amount of food and even the specific method. In the first few weeks, you can monitor your diet 24 hours a day. After getting familiar with it, you can visually check the calories of each food and estimate them in your mind.
After knowing your own consumption, you can start to calculate sports consumption. The most direct way to lose weight is aerobic, and most aerobic devices (treadmills, elliptical machines, etc. ) comes with a calorie counting function. As for the calculation of outdoor aerobic exercise, I recommend water flower exercise.
This app can measure outdoor sports such as running, cycling and skiing. Calculate the calories burned according to our information (or weight and age), and also give the time per kilometer.
