There are a few key hormones that impact metabolism and weight loss. They really all have one thing in common, blood sugar.
If our blood sugar levels become too high, this sends messages to all sorts of areas in the body which try to counteract it by sending out other hormones to deal with it, ultimately resulting in the excess blood sugar being stored as fat.
5 hormones that affect blood sugar levels, hormones and weight loss
Leptin is one of these hormones. Its job is to let us know we are full. Excess sugar in the blood gets turned into fat by the liver, and this increases leptin. Sounds like a good thing, but too much leptin telling the body we are full, and the body begins to ignore the message, leading to leptin resistance, and ultimately overeating, as the body can no longer recognise when it is full.
The hormone that is supposed to work in harmony with leptin is ghrelin. This hormone is released when you are hungry. In obese people ghrelin’s message is much more sensitive, and the result is an increase in blood glucose concentrations and more hyperglycameia. We know what excess blood glucose ends in: the sugar is stored as fat.
Sleep deprivation can increase ghrelin levels, explaining why you feel hungrier after a bad night’s sleep.
Oestrogen is a hormone that comes into play as well. Excess oestrogens in the body can be a result of eating hormone-laden meats, excess plant oestrogens like soy, and exposure to xeno-oestrogens in our environment. The xeno-oestrogen’s are pretenders and trick the body into thinking they have more oestrogen than they do.
These are present in soooo many things in our world – plastics, perfumes, pesticides, birth control pills, nail polish. The list goes on! What you need to know is what happens when the body goes into “oestrogen dominance”. It tips the balance of your sex hormones and results in conditions like insulin resistance and PCOS. Insulin resistance raises blood sugar levels, and again, the sugar is stored as fat.
Cortisol is a hormone that we release when stressed. It is one of our fight or flight hormones. A little bit is good for the body, it wakes us up in the morning and gets us on with the day. An excessive amount of cortisol is telling the body there is a catastrophic event to prepare for, and it does this by converting blood sugar to fat stores. The number one thing we do to stimulate excess cortisol is drink caffeine! Stress management is super important for this hormone, as emotional, physical and imagined stress all stimulate cortisol production.
