having a very high amount of body fat in relation to lean body mass, or BMI of 30 . If exposed to high fat diet consistently- leptin and insulin receptors are down-. Describes how the leptin test is used, when a leptin test is ordered, and what the Leptin is a hormone that helps regulate appetite by signaling hunger satisfaction (satiety). .. Physical activity energy expenditure may mediate the relationship between plasma leptin levels and worsening insulin resistance. Is Leptin Resistance the new Insulin Resistance? for insulin resistance, which helps explain the relationship between above-average weights.

You are not very hungry, but you think, "l'll just have one little piece. What's going on here? Even though you are not physically hungry, your body gave you the signal to eat. That's the work of three hormones in your body that control hunger -- insulin, ghrelin and leptin. They are important because the way these balance can impact your weight and health.

Is Leptin Resistance the new Insulin Resistance? How Hormones Are Making You Fat

Insulin Insulin is made in the pancreas and allows cells to take sugar or glucose from the blood stream to use as energy. Approximately one-third of the population inherits a resistance to respond properly to insulin, which prompts the pancreas to secrete more insulin if you eat a meal high in refined or "simple" carbohydrates such as white pasta or white bread.

When the insulin does not respond normally -- allowing sugars to enter the cells of the body -- you can experience insulin resistant hunger. Rather than being physically hungry, you might experience it as a "gnawing" desire to eat.

If you consume meals high in refined carbohydrates on a regular basis, that are not balanced with respect to protein and good fat, you may continually crave carbohydrates. Again, even though you were not physically hungry, your body gave you the signal to eat. In these situations, you know what you are "supposed" to be eating, but your body continues to give you the signal to eat more carbohydrates. And yes, we can choose what we eat and how much we exercise, but we do not choose our genetic makeup.

It is one thing to do all the right things to lose weight like eat well, get adequate sleep, exercise, quit smoking yadi-yadi-yada… but maintaining that weight loss in people who are just not predisposed to maintain that weight loss is a whole other story. This may be where insulin resistance and leptin resistance come into play. Insulin Resistance Insulin allows glucose aka. Insulin is like a key and its corresponding cell receptor is much like the lock.

When the two make nice, glucose enters the cell to be used as fuel. However, in insulin resistance, the key and lock mechanism become out of sync. The guy pancreas sends more flowers insulin to the girl in hopes that she accepts his love glucose. But the girl the cell just keeps resisting his advances. The guy keeps sending flowers only to be denied, and eventually he becomes exhausted and gives up.

An exhausted and lonely pancreas can no longer produce sufficient insulin to keep up with insulin resistance. Since the rejected glucose is left outside the cell, higher than normal blood levels can damage the body over time.

Serious complications can include neuropathy, blindness, and cardiovascular disease. Insulin resistance best describes type 2 diabetes which we know can be linked to lifestyle and dietary habits. In contrast, Type 1 diabetes is when the body produces no insulin so it has to be supplied in the form of a vital injection. Excess body fat actually increases the risk for insulin resistance, which helps explain the relationship between above-average weights and diabetes. Leptin Resistance Leptin is a hormone produced in adipose tissue and it is responsible for satiety or how full we feel after we eat as well as regulating energy-expenditure and weight loss.

This curious hormone has a negative feedback to energy intake, which simply means that leptin levels rise as you consume more food. In obese individuals with insulin resistance, leptin levels have been correlated with the amount of fat on the body.

The more fat you have, the more leptin you have drifting around your body. In other words, fruit, which has fibre," Lustig said.

There are two types of fibre: Soluble fibre is like the pectin which holds jam together, and insoluble fibre is like cellulose like the stringy stuff in celery. You need both -- and fruit has both. Then the soluble fibre plug the holes in the net," Lustig explained. We don't absorb it for our own use or storage, Lustig explained.

There's something in the second part of the intestine that's not in the first part -- bacteria. Those bacteria have to eat to live. And that lets the good bacteria grow, which means the bacteria chew up the energy instead of you absorbing it. That's a good thing. Fibre is the reason fruit is okay. That's what is not okay. For example, fruit juice," Lustig said. Real food is low sugar and high fibre. Processed food is high sugar and low fibre. It turns out it's not.

Processed food is how we go into this mess. In Lustig's words, "It's called real food". And thanks to fibre in fruits, vegetables and unprocessed complex carbohydrates, a calorie is not a calorie if it comes with fibre. The primary reason is because if you're consuming the food with fibre, even though you ate the calories, you didn't absorb the calories, so the mass is irrelevant because they weren't yours it was the gut bacteria's ," Lustig said.

It's why we have 40 years of unsuccessful obesity therapy around the world.
