Bear with me boy’s I promise this is not a dressed up Bodyform advert, this is still relevant to the male species and if you read on you will find out why.
High Levels of Oestrogen are commonly linked with weight gain and high fat levels. But which comes first – Chicken (Sorry Hen, Sorry Mr A!) or the Egg? Does the fat cause the Oestrogen, or does the Oestrogen cause the fat?
Simple answer…………………………….It’s both! Glad we’ve cleared that up!
Firstly, increased fat cells increase the production of Oestrogen, and secondly high levels of Oestrogen slow down metabolism and therefore encourage your body to hang onto fat. Hence a vicious (probably emotional with all that oestrogen!) cycle.
Oestrogen causes weight gain by inhibiting thyroid function. Ordinarily Oestrogen and the Thyroid play off each other in an evenly matched game of tennis. However if Thyroid function becomes impaired through such things as high or low blood sugar, due to an Insulin imbalance then that game is no longer evenly matched. Think Andy Murray playing me, I’ll give you a clue I can’t even hit the ball! So impaired Thyroid function = Impaired Oestrogen Function.
The reason this is not just a ladies issue is because testosterone is converted to Oestrogen by an enzyme called Aromatase. Aromatase is the primary source of Oestrogen in men-and you thought you were safe from its clutches!
Aromatase is present is all types of body tissue however the vast majority of it is found in the adipose tissue –that’s body fat to you and me. So boys the more fat you are carrying, the more Oestrogen you’re carrying – hence the man boobs!
However this is where is gets complicated – take a bite of your hot cross bun…………………………. Oestrogen actually plays a large role in weight loss! Don’t spit it back out, it’s true and I shall now in as simple a manner as possible explain why. Without dropping the real science because I know you intelligent folk love it.
Oestrogens presence within a cell decreases the uptake of Lipoprotein Lipase – LPL. LPL encourages fat uptake of a cell, therefore the presence of Oestrogen stops this from happening. So Oestrogen stops cells picking up fat???
Secondly, Oestrogen increases the activity of Hormone Sensitive Lipase-HSL. When HSL is stimulated by Epinephrine it incites the breakdown of fat, this occurs most commonly during exercise, so basically Oestrogen is burning fat whilst you’re on the X Trainer-Cool Huh!
And thirdly, Oestrogen can also stimulate the production of Growth Hormone, which in turn inhibits Insulin Production and forms part of your blood sugar control. It is also inhibits the uptake of carbohydrate for energy and therefore encourages the burning of fat. Yes I’m confused now too!
To be honest the scientists are still scratching their heads a little on this, however what can be proven is that upsetting the apple cart of your other weight loss hormones i.e. Insulin Cortisol, Leptin, Ghrelin has a knock on effect on your Oestrogen function and it should therefore be considered as part of the process.
So I will kick on with what affects your hormones a little more next week , after you’ve all spent the weekend becoming Easter Egg Shaped, if anyone needs me I will be head first into a giant Walnut Whip.
