Sensory lines are also the line that thousands of men and women dream of. Mermaid lines are called one of the sexiest parts of the human body.

Why do you have tuna belly and swimming ring?

1. Tasteful and lazy

The main reason for a big belly is: eating too much and moving too little!

The body will store too much nutrients (calories) you eat in the form of oil and put them in the tissues of the whole body. Of course, this includes the internal organs in the body. The most common one is fatty liver. It is triglycerides in the blood vessels, and it is a big belly.

The more you eat and the less you move , the better your body's ability to store fat, you can imagine how much oil there will be on your body?! Can your belly not be big? However, although a big belly that can be seen is a worrying thing, fatty liver and triglyceride fat that cannot be seen is probably not a good thing.

2. Problems between spine and pelvis

In fact, a big belly may not be just a problem with too big belly. The "skeleton" that supports our belly is too prominent, which will also make our belly look bigger. There are two most common ones:

The upper abdomen is convex, that is, the pelvis is tilted forward, guide When the lumbar spine is overstretched, it is like pretending to be pregnant while acting and lords the lumbar spine will lordate. At this time, our pelvis will be too tilted forward.

　　Especially for ladies who often wear high heels, because their heels are raised, the body will bend forward and the pelvis will be tilted forward at the same time, and the upper abdomen will be protruded, making the belly bigger. At this time, if you have a lot of "abdominal oil", then your belly, especially the upper abdomen, will be too obvious. Moreover, such a body will also cause excessive pressure on the lumbar spine, which will often cause waist pain.

　The lower abdomen is bulging, the pelvis is tilted backward. It leads to the lumbar spine curve and the hips are overstretched, just like the body sitting in a soft sofa, the lower abdomen will naturally bulge forward.

This pelvic position will almost make people unable to stand straight, and it is almost difficult to use the strength of the hips. The legs will be exerted a lot, and the pressure on the knees will be particularly high. Therefore, it is important to straighten the body and use the core strength of the hips.

3. Deficiency of sleep

We all know that sleep is important, but few people know the relationship between sleep and weight.

We seem to have a specious concept: sleep less so you won’t get fat. It seems that sleep is one of the murderers of getting fat. In fact, on the contrary, adequate sleep is the key to slimming and turning into a tuna line!

　　Reason 1, the most important time for our body to metabolize too much fat is when we sleep, especially when we sleep deeply. Even when we sleep deeply, the energy source of the body is almost 100% of the body's energy comes from the body's fat. Therefore, good quality sleep is an important step to slimming.

　　Reason 2, when we sleep, we secrete "leptin". As the name suggests, leptin is the endocrine that stimulates the body's metabolic body fat efficiency. If we lack leptin, our body will reduce the metabolism rate of oil. With the secretion of leptin, the body can naturally become thinner even when lying down. .

　　So, good quality and adequate sleep are important factors in slimming waist and weight loss.

4. Emotional and stress issues

　　Many people exercise much more than ordinary people, but sometimes they find it more difficult to relieve their stomachs than ordinary people. At first I was puzzled. Although they ate a lot, they exercise more, but their stomachs are not small.

Later I found that this type of people is usually not easy to self-relieve when they are under great pressure and are often anxious because the stress hormones will be anxious. Secret secretion when you are worried. This endocrine will inhibit the metabolism of body fat. So even if you exercise a lot, your body will use other substances to provide calories, which will leave the body oil. This condition will reduce muscle mass, increase body fat rate, increase belly, and worsen physical strength.
