We have adipose tissue all over our bodies. This tissue is made of adipocyte (fat cells) and its sole job is to store energy in the form of fat. There are generally 2 types of bodyfat:
- visceral – surrounding the organs,
- subcutaneous – beneath the skin, 80% of bodyfat.
Body fat comes in different colours:
- white is the fat that makes up 90% of your bodyfat. It has a very low metabolic rate, so it doesn’t burn calories therefore it is more like a storage unit for calories.
- brown fat can burn calories because of its rich blood supply. Unfortunately we have very little of them.
- beige fat is in between white and brown in terms of calorie burning capacity.
Losing stubborn bodyfat is not easy. According to some studies: spot reduction does occur, however it occurs on such a marginal level that it is insignificant. Your body will burn the fat from areas where it’s easier to get rid of it. That’s why when you start a diet and exercise program, some of your areas in your body look leaner and you can recognize the progress quicker and easier, and there are other areas that look ‘unchanged’. Your body burns the fat all over, but burning the stubborn fat is more difficult and takes more time.
Stubborn fat is physiologically different than other fat. There are 2 different types of receptors in fat cells: noradrenaline and adrenaline. These hormones bind receptors in fat tissue that send the signal to speed fat release of slow fat release. These receptors are the alpha and beta-receptors. Alpha receptors slow down the fat release. Beta receptors speed up the fat release. Stubborn fat has a high density of alpha-receptors compared to betas, is more insulin sensitive and receives less blood flow than less stubborn fat. Subcutaneous fat is more stubborn than visceral fat or intramuscular fat (fat in your muscle). The most stubborn areas of fat are hips, butt, thighs of women, and the love handles for men.
To burn fat you have to release it from a fat cell (lipolysis). That fat then has to be brought inside of another cell and be burned. That’s why the blood supply to and from the tissues is important. Stubborn fat releases its fat more slowly than non-stubborn fat. Stubborn fat is more insulin sensitive (or less insulin resistant) than regular fat. A fat cell that’s more insulin resistant stores less fat and releases more of it. Other hormones have an effect on fat release, too. Thyroid activity ramps up beta receptor activity and turns down alpha receptor activity. Estrogen increases the alpha receptor activity – that’s why during the female cycles stubborn fat is more stubborn.
Stubborn fat has less blood flow, therefore even if it gets released it doesn’t get moved out of the area to be burnt easily. Alpha receptors impact blood flow. More alpha receptors = less blood supply. Also, stubborn fat is in areas that are harder for the body to heat up: love handles are further away from the center of the body.
One of the things people tend to do when they want to burn stubborn body fat is they go on a diet and exercise more. It can work out at the beginning, when you clean out your diet, start counting your macros and start an exercise regime. However if you’re not preparing for a competition, then you need to think of other ways because this way in the long run you only reduce your BMR (basic metabolic rate) which means you will need less and less calories and eventually your body will go into ‘starvation’ mode and start storing the fat instead of burning it. To come off the diet you can either eat less and exercise less (ELEL) or right the opposite: eat more and exercise more (EMEM).
- ELEL allows a very low calorie or low carb diet because you reduce your resistance training and cardio during the week therefore you don’t need high calories but you don’t burn that many calories either because of the lack of exercise. This doesn’t mean you have to sit in front of the TV all day. You should still go for a walk and do low impact cardio on a daily basis. The key word here is ‘low impact’.
- In the EMEM approach you increase your calorie intake but you also increase the intensity of your workouts. This approach is better and more healthy because high intensity workouts and more food will also increase your metabolism and your fat burning.
You need to bear in mind that metabolism is very reactive and adaptive. It differs from person to person how long it takes your body to adapt but sooner or later it will. To avoid this you need to cycle your diet and that keeps your metabolism guessing.
