Are you facing difficulty in losing belly fat? Does even after following a strict diet regimen and workout routine, you have not losen your stubborn belly fat? Have you ever think what would be the reason behind your stubborn belly fat? So here I am going to discuss the very basic and scientific reason for that.

The process of burning fat should be more like that after dieting and working out, we should lose fat equally from all parts of the body, but this is not so. Different areas of body respond differently to diet and workout. Some parts of body loses fat very easily and some parts resist fat loss.This depends on many factors like your age, gender, hormonal influence, underlying health conditions. The very basic reason is that this depends on the type of fat cells present in that area.

According to the response to energy levels of body, Fat cells are categorised into two types.

• Alpha fat cells
• Beta fat cells

Every fat cells have two types of receptors on ther surface. Alpha receptors and Beta receptors. Every fat cells have two types of receptors on ther surface. Alpha receptors and Beta receptors. Fat cells will have both of these receptors but which receptor is more in quantity than other will decide the type of fat cell. Fat cell havibg more alpha receptors will be alpha fat cell and fat cell having more beta receptors will be Beta cell. Alpha fat cell stores fat more than burn. Beta cell burn fat more than store.

1. Alpha Receptors – Alpha receptors enhances the storage of fat in the fat cells. Alpha receptors reponds to ” insulin” at the time of “ High Energy State” ( High energy state means, when your body has excess glucose in the blood than required ). When body has raised blood glucose levels, then insulin detects it and insulin blood levels also increases. Insulin tries to shift this extra glucose from the blood to maintain the normal blood glucose levels, because blood glucose levels above or below normal range is harmful. Insulin does some changes which enhances the glucose conversion into fat. This process takes place in liver.

• Insulin increases the uptake of glucose into liver,
• Insulin enhances the lipogenesis, production of fatty acid from glucose, and then from fatty acids and glycerol, the formation of Triglycerides.
• Insulin activates the alpha receptors on the fat cells, inceases the uptake of fatty acids and glucose which will finally stores as triglycerides in fat cells.

So the areas which have more alpha receptors than beta receptors will store the fat fast and burn the fat slowly. For example – Belly, thighs, hips.

2. Beta Receptors – Beta receptors enhances the moblisation of stored fat, so promotes the fat burn process. Beta receptors responds to the Glucagon, Epinephrine,Nor-epinephrine, growth hormone… When the body is in ” Low Energy State / Fasting State” ( low energy state means when blood glucose levels drops down below normal range.) So these hormones detects the low level of glucose in the blood and tries to moblize the stored fat out of fat cells, so that body uses fat for energy production. So these hormones activates the beta receptors on fat cells and this activated beta receptors enhances the fat moblisation process. The areas of body rich in beta fat cells are face, chest, arms, back.. Here in these areas fat loss is easy and quick.
