Several signals that the body is burning fat:

1 Reduce hunger and enjoy fasting. When the body burns fat, it will enter a state of nutrition and ketogenesis. In this state, you won't have a strong hunger, and you won't crave carbohydrates or sweets. You will enjoy an empty stomach and won't eat because of gluttony. One study involved 20 obese adults who received a four-month staged diet, combining a ketogenic diet with a low-calorie diet. The results showed that the subjects' desire for food decreased significantly. In addition, during the ketogenic period of 60-90 days, participants did not report the typical symptoms of severe calorie restriction, including sadness, depression and increased hunger.

You can easily stop eating and skip a meal. Burning fat is a stable energy source, unlike eating carbohydrates, especially simple carbohydrates such as sugar, which fluctuate greatly. When you reduce your carbohydrate intake and adapt to fat energy supply, you can burn a lot of body fat at any time. Ketones can also suppress hunger, you can easily skip any meal, and your body will use its own fat to provide you with energy. This is called intermittent fasting. When you get used to fat for energy, it's easy to have one or two meals a day. If necessary, humans have the ability to run for weeks on their own fat reserves and stay energetic. This is the reason why many people have better energy after fasting for a long time, but it is a bit extreme and not necessarily recommended, but it shows how strong the ability to adapt to fat burning is.

3 hungry and fat. When your body adapts to fat to get energy, your body will burn fat in a ketogenic state, so when you lack energy, your body will crave fat instead of sugar. Many people will find that they don't like sugar and staple food after living a ketone life, but they can't stop watching salmon.

3 emotional stability. There is no big fluctuation in blood sugar, and the blood sugar is stable. Naturally, there will be no anxiety, hunger and irritability due to hypoglycemia. Ketone can relieve various psychological problems such as depression and anxiety. Many people can improve mental problems such as chronic anxiety and depression after adapting to fat energy supply after low carbon.

4. Quick thinking and clear mind. After getting used to the energy supply of fat, the ketone feeling will fade away, and soon, you will feel many benefits. After burning fat, ketone bodies will be produced, which is an excellent fuel for the brain. Many studies have found that ketone bodies can enhance the memory, attention and task switching ability of the elderly. Moreover, in another study, it was found that too much glucose can reduce the speed, cognition and memory of the brain. If you stick to a low-carbon ketogenic diet for several weeks and feel sharp and clear-headed, it is likely that you have adapted to fat energy supply.

5 exercise endurance is enhanced. From 65438 to 0980, Steve Phinney, a sports researcher, and his colleagues found that the endurance of the body can be enhanced after adapting to fat energy supply. The design of this study is very simple. Without training, overweight people eat a high-carbon diet for two weeks, and then a ketogenic diet with limited calories for six weeks. Fini and his colleagues measured endurance performance and fat oxidation ability before and after changing diet. Participants burned more fat and ran longer in the state of adapting to ketone than in the state of high carbohydrate. If your body adapts to fat energy supply and fat becomes the main fuel for exercise, you can store glycogen (stored glucose) for a longer time. When extra fuel is needed after long-term or high-intensity exercise, glycogen will come in handy and become an auxiliary material rather than a main material. For sports enthusiasts, increased endurance is also a good sign that your body adapts to fat energy supply.

6 body fat is reduced, especially visceral fat. Once you get used to the fat energy supply mode, when you need energy, your metabolism will learn how to burn adipose tissue (the body's own fat) as fuel. After a low-carbon diet for about a month, you lose weight, which may be because you have adapted to the fat burning mode, and your body can make good use of body fat to provide you with energy. Your body fat, especially visceral fat, will drop rapidly.

Judging that you burn fat is actually very simple, because the state of burning fat and burning sugar is completely different. Everyone who binges on carbohydrates during the holiday will have a deep understanding. After burning fat, your energy level, food craving, attention, concentration, mood swings and endurance are all different. Of course, if you are still uneasy, you can choose some medical instruments, such as measuring your blood ketone and your breath ketone, to know more about your fat burning state, whether it is fast or slow.
