There are many different ways to gauge whether or not you are burning fat. Here are some signs that your body is in fat-burning mode:
1. You have more energy.
When you burn fat, you convert it into usable energy for your body. This means that you'll have more sustained energy throughout the day and won't feel as tired as you would if you were relying on sugar or carbs for energy.
2. You're losing weight.
This is perhaps the most obvious sign that you are burning fat. As your body converts stored fat into energy, you will start to see the pounds come off. Keep in mind that weight loss isn't always a linear process, so don't be discouraged if the scale doesn't budge every day.
3 . Your appetite decreases .
Another common sign of fat burning is a decrease in appetite. When your body is using stored fat for energy, it doesn't need to replenish those stores as often, so you'll likely find yourself eating less often and feeling satisfied with smaller meals .
