Stubborn Fat

Losing fat at different body parts is not always the same strategy. Fat accumulated at certain areas such as shoulders, thighs, and bellies are stubborn; they are much harder to get rid of compared to other body parts. So, we need powerful and effective medical beauty technologies to treat stubborn fat.

What is stubborn fat

Stubborn fat is hard to lose and subcutaneous fat is one of the examples. It is easy to accumulate but difficult to get rid of. When excess normal fat is burned, the body then begins tackling excess subcutaneous fat. This type of fat has high fat tissue density and stronger correlation with insulin sensitivity. Among all consumable fat types, stubborn fat has the least blood flow.

When we look into the chemical composition of fat, we will understand why stubborn fat is difficult to get rid of. Stubborn fat has more α-adrenergic receptors while normal fat tissue has more β-adrenergic receptors. The main function of α-adrenergic receptors is to inhibit the activity of lipase, regulate the energy supply to the muscle during exercise, and inhibit the burning of fat. In contrast,  β-adrenergic receptors can promote the activity of lipase, strengthen muscle contraction, and speed up fat burning. Therefore, stubborn fat is more sensitive to insulin, has lower blood flow, is harder to burn than visceral and intramuscular fat.


There are internal and external causes of our body storing stubborn fat.

◎ External Factors:

1. Poor Sleeping Patterns

Poor sleep patterns can lead to endocrine problems, which inhibits the release of adrenaline to burn fat. Also, staying up late, lack of sleep, and being under stress for a long period of time will stimulate the secretion of cortisol, which will encourage weight gain and the storing of stubborn fat. Adjusting your sleep patterns is the first step to control your weight.

2. Eating Habits

Poor eating habits such as excessive food consumption of high sugar, calories, or fat will lead to weight gain. Also, a high carbohydrates diet, including refined carbohydrates such as white rice, noodles, bread, will lead to blood sugar spike and insulin spike, causing the formation of stubborn fat.

3. Lack of Exercise

Sedentary lifestyle or lack of exercise encourage the transformation of unused energy into fat tissue. Fat is more likely to be stored as stubborn fat.

4. Ageing

The major energy consumption by the body is basal metabolism, followed by physical activity and the thermic effect of food. When we are younger, the higher levels of testosterone and growth hormone help to maintain a higher basal metabolism. But when we age and lack exercise, the basal metabolism will decline and make it more difficult to lose fat.

◎ Internal Factors:

1. Sensitive to Insulin

Insulin can speed up the storage of fat. Fat in certain parts (such as waist, abdomen, thighs, etc.) is particularly sensitive to insulin, which leads them more likely to store fat.

2. Slow Blood Flow at the Fat Tissue

Blood flow can affect the fat metabolism in the area. Blood flow varies in different parts of the body, for example, blood flow at the thigh/hip is slower than that at the arm/ chest. It means that our body parts have different fat metabolism. Areas with slow blood flow have lower fat metabolism performance and lower content of lipolysis-promoting hormones like catechol as they can not get into fat cells easily. As the blood flow at stubborn fat is low, the fat cells can stay away from being killed and transported out from the fat.

3. Lower Body Temperature

Stubborn fat has a lower temperature than the rest of the body. A lower temperature will slow down the process of the fat burning, which will encourage the storing of fat and stubborn fat.

4. Oestrogen

Not only can insulin affect the building of stubborn fat, oestrogen is also one of the factors that increases the activity of α-adrenergic receptors. Therefore, women, typically have a higher level of oestrogen than men, will have more stubborn fat than men.

Symptoms and Affected People

Compared with normal fat tissue, stubborn fat is easier to accumulate in the body, but also more difficult to lose even if you are on a strict diet and follow a workout schedule.

Everyone has their own distribution of stubborn fat, which is determined by genetics and lifestyles, and can not be altered. Some are at their belly, some are at their legs (like myself).

When will the stubborn fat be tackled? Only when the normal fat tissue is burned, the body begins to tackle stubborn fat.

Women mostly suffer from stubborn fat at their buttocks, thighs, inner thighs, lower abdomen, and upper arms. Men’s stubborn fat can be mainly found at the lower abdomen around the belly button and both sides of the back waist.


In general, we can lose the normal fat tissue by regular exercise and diet. And stubborn fat can be treated separately by localised fat reduction therapies.

In Ai Beauty Clinic, you can simply lose fat at specific body parts by the Lipodissolve Injection or CoolSculpting which can effectively break down fat cells and provide accurate localisation of fat reduction. Or you can lose fat and build muscle at the same time by BTL EMSCULPT, creating a firm and slim body contour.

A. CoolSculpting Elite

What is CoolSculpting:

CoolSculpting Elite system is a fat freezing treatment system developed by renowned dermatologists Dr.R.Rox Anderson and Dr. Fieter Manstein at Massachusetts General Hospital (A teaching hospital of Harvard Medical School), and manufactured by American medical equipment manufacturer ZELTIQ AESTHETICS, INC.. The system has been widely used in more than 80 countries globally with more than 5 millions successful practical cases. This technology has been certified by the US FDA, China CFDA and CE. Its safety and prominent results have granted the CoolSculpting technology to be a world class body sculpting treatment.


Based on the cold-intolerance property of fat cells, CoolSculpting technology utilises low temperature (4~5℃) applicators to chill the unwanted fat cells. Fat cells will then die and be excreted out of the body as they can not tolerate low temperature. The accurate temperature setting and the usage of the applicator probe ensure that the process will not damage any normal body tissues except fat cells. Thanks to the high accuracy and specificity, one treatment can achieve a removal of 22.4% fat.


1、Face-to-face consultation: Evaluation of bulges including location and size. Doctor will provide a suggested treatment plan based on your situation and expectation.

2、Pre-treatment: Draw markings to define treatment areas. Clean, disinfect and install the tip of applicator.

3、Sculpting treatment: Place the applicator probe against your skin to deliver cooling to fat cells.

4、Post-treatment caring.

Duration: 1 hr

Who is it for:

  • People who are not significantly overweight but looking for a fat reduction at specific body parts;
  • People with severe problem of stubborn fat;
  • People who want a non-invasive fat reduction treatment without any involvement of surgical operation, liposuction or general anaesthesia;

B.Lipodissolve injection

What is Lipodissolve injection:

Lipodissolve injection is considered the most safe and effective non-surgical fat reduction treatment, it works particularly well on localised fat reduction such as double chin, chubby face, arms and legs. Lipodissolve injection boosts the metabolic rate of fat tissue, enhances digestion of fat cells, and tightens and lifts the skin.

How does it work?

Lipodissolve injection solution will be administered locally to the subcutaneous fat layer. The active ingredients in the solution will break down the walls of fatty cells and increase the localised concentration of lipase enzymes to facilitate the destruction of fatty cells and let the body flush out the fat as waste via the lymphatic system.


1. Face-to-face consultation: Doctor conducts evaluation of the thickness of the double chin and provides professional advice on whether or not a lipodissolve injection treatment is suitable. If suitable, the injection site will then be marked on the face.

2. Pre-treatment preparation: Local anesthetic. Clean and disinfect the injection areas.

3. Injection: Administered with blunt needles at the double chin. Only one injection at each injection zone.

4. Post-treatment precautions.

Duration: 30-45 mins

Who is it for?

  • People who have problems of stubborn fat at troubled areas around the body including shoulders, inner thighs, joints, abdomen, etc;
  • People who have fat deposited in their body and want to eliminate cellulite;
  • People who are experiencing uneven skin texture after liposuction treatment;
  • People who want a non-invasive fat reduction treatment without any involvement of surgical operation, liposuction or general anaesthesia;
  • People who lack exercise;
Ai Beauty Lipodissolve Injection:

Two UK proven lipodissolve injection solutions are available from Ai Beauty: Aqualyx (United Kingdom) and Desobody (Italy). They both can accurately and effectively dissolve the unwanted fat deposits, the result is long lasting without rebound. This non-invasive, localised treatment is a worry-free option for fat reduction.

Developed by BTL, BTL EMSCULPT is an innovative device that can simultaneously burn fat (19%) and build muscle (16%) by a non-invasive technology. The device offers effective and safe results without emitting any radiation, freezing or high temperature that may damage the epidermis. BTL EMSCULPT has been certified by the US FDA, CE and TGA, and supported by 7 pieces of independent academic research in the United States. EMSCULPT is the same technology that Kim Kardashian has used for shaping her figure.

How does it work:

BTL EMSCULPT adopts a breakthrough technology called High-intensity Focused Electromagnetic Technology (HIFEM) . In only 30 minutes, an energy pulse will stimulate muscle contraction for 20,000 times. The electromagnetic wave emitted from the well designed applicator can penetrate up to 7cm depth of the muscle layer in order to trigger extreme muscular contractions that the human body cannot achieve autonomously. These contractions facilitate fat burning (by increasing breakdown of fat cells) and muscle building and strengthening.


1、Face-to-face consultation: Customise a unique treatment plan for each client based on their condition and desired result.

2、BTL EMSCULPT: Place the applicator tip onto the treatment area, gradually increase the energy intensity.

3、Post-treatment precautions.

Duration: 30-45 mins

Who is it for:

  • People who are not significantly overweight but looking for a reduction of stubborn fat at specific areas such as shoulders, abdomens and buttocks;
  • People who have loosen skin and want to reshape their body contour and tighten their skin
  • People who want to build muscle and burn fat at the same time;
  • People who want a non-invasive fat reduction treatment without any involvement of surgical operation, liposuction or general anaesthesia;
  • People who lack sufficient exercise and want to lose fat healthily;

BTL EMSCULPT is a fat reduction/muscle building exercise device that only requires you to lay down and causes no sweating. This non-invasive treatment simulates a high frequency exercise to burn fat and hence reshape body contour scientifically and healthily. Ai Beauty Clinic is one of the first aesthetic clinics to introduce BTL EMSculpt in the UK.
