The role Leptin plays and its affect on weight loss

I’m thrilled today to be writing a blog that has been requested by one of my Facebook followers. The topic is Leptin and how it affects weight loss. Here is my way of explaining the role Leptin plays in the most simplistic way.

Leptin is a master hormone in the body that controls your hunger and feelings of satiety. Leptin is secreted by adipose (fat) tissue, so the more overweight a person is, typically, the higher their leptin levels.

If your leptin signalling is working properly, when your fat stores are “full,” this extra fat will cause an increase in your leptin level, which signals your brain to stop feeling hungry, to stop eating, to stop storing fat and to start burning some extra fat off.

Over time, if your body is exposed to too much leptin, this can lead to Leptin resistance which is where your brain does not receive the message that you are full from eating, therefore you keep eating and keep storing fat – this can lead to obesity. The Leptin hormone can be resistance and not work properly if your body has too much insulin roaming around in your blood stream from eating too many carbs or sugars. The more leptin resistant the body becomes, then the more the body tends to stay the way it is or put on more weight rather than losing it.

What is Insulin? Insulin is a storage hormone and is produced into your blood stream when you eat carbs or sugars – the more you eat the more insulin will be produced. In today’s world there are so many yummy tasty foods that are made up of carbohydrates and of course sugar but eating too much of these leads to blocking your leptin signals so the brain has no indication of whether you are satisfied or still hungry, resulting in storing more fat. Many people these days are Leptin resistant and there are many health problems tied to this problem. High leptin levels have been linked to high blood pressure, obesity, heart disease and stroke, as well as blood sugar related problems.

The only known way to re-establish proper leptin signalling is through your eating and choosing better options. Eating a variety of whole foods is the way to go to ensure your leptin response is working properly.

So what is the plan of action to take to keep your Leptin hormone working well and communicating with your brain, here are some helpful tips:

  • Eating more protein as it has minimal effect on insulin levels.
  • Reduce the amount of simple carbohydrates you eat being – e.g. white bread, lollies, chocolate, biscuits etc
  • Choose complex carbohydrates like grains, vegetables which contain fibre this will release insulin into your blood stream slowly giving our cells more time to use the energy.
  • Regular exercise will help in burning up the excess blood sugar
  • Eat frequently throughout the day, as the more you eat in one sitting the more insulin will be released into your blood stream.

So if you have struggled with your weight for some time slowly begin to eat more of the ‘good’ stuff and minimise the treats to get you on the right track and allow you brain to receive the correct messages.

Stay healthy
