Have you ever ever been told that the cure for obesity is simple? Stop consuming so many calories and do exercise? If only it was so easy!

It can be frustrating for people to minimise the wrestle of weight reduction to this ‘easy advice’, as if it was really easy, there certainly wouldn’t be so many overweight and overweight individuals making an attempt to lose weight.

There are so many factors that contribute to weight loss and weight acquire – and more and more research suggests that the hormone leptin and obesity might be linked.

Leptin is typically referred to as the ‘starvation’ or ‘satiety’ hormone, and it’s possible in your body to be proof against it. And, when it involves fat gain, leptin resistance might be a main contender.

What’s leptin?

Leptin was first discovered in 1994 and generated quite the buzz on the planet of weight loss, with individuals speculating that it might be the subsequent big thing to help you lose weight.

That’s why it was names after the Greek world ‘leptos’, meaning thin.

It’s an amino acid hormone that our fat cells make and distribute into the blood stream to tell our brain that the quantity of energy we’re taking in (through food and drink) is adequate.

Circulating leptin hormone levels within the body inform our central nervous system to adjust food intake and energy expenditure accordingly, e.g., by making us really feel hungry after that gym session or making food appear less interesting if we have now met our ‘appetite quota’ on a less active day.

Leptin may even have an effect on when we start puberty or our possibilities of getting pregnant, because the body will ‘consult’ leptin levels to see if it has enough energy to spare for these processes.

Abstract

Leptin is an amino acid hormone that our fats cells produce

It is distributed around the body and into the brain to help make certain the amount of energy we’re taking in matches what we’re using

What stimulates leptin?

There are a number of things that may stimulate your production of leptin, together with:

Insulin – a hormone that allows your body to make use of sugars from meals

Glucocorticoids – steroid hormones, usually used to tackle inflammation

Serotonin – our temper stabling hormone, aka the completely happy hormone

Oestrogen – one of many main feminine sex hormones

Leptin and dieting

Leptin production and regulation could possibly be significantly affected by dieting.

It’s thought that the bottom level of leptin our body is set by our genetics, that means that we always have personal leptin ‘threshold’.

If our leptin levels meet or exceed this threshold, our brains are glad to let us go about life as normal – consuming food at a mean rate and being able to train after we need to.

Nevertheless, when most people weight loss program, they eat less meals and their our bodies lose some fat cells.

As our fats cells produce leptin, this causes our leptin levels to decrease. This causes the body to react in a very similar way to if we have been starving.

Sure, we’ve evolved since then, however our body will still really feel like we’re in danger when we reduce our energy intake.

During this perceived hunger, our body will ramp-up a number of processes to assist replenish these leptin levels, including stimulating the vagus nerve.

The vagus nerve runs between the abdomen and the brain; its predominant job is to monitor and management energy storage.

When you’re dieting, your vagus nerve turns into hell-bent on making you consume extra energy to store in your fat and convey leptin levels back as much as your personal threshold.

This is without doubt one of the reasons why a chocolate you don’t even like that a lot can turn out to be downproper irresistible while you’re on a weight-reduction plan, or why when you finally ‘allow’ your self to have a small portion of ice cream, you end up scoffing the whole tub.

This is just what your vagus nerve wants!

So why will we gain weight if we simply comply to what our our bodies need?

In a perfect world, all of our weight points can be solved by listening to our body and our cravings to restore leptin levels back to their threshold.

But if that was the case, why do more and more people become obese and overweight because the years go on?

One principle is that leptin resistance plays a part.
