Video: Robert Lustig – Fat Chance: Fructose 2.0

Published on October 28, 2013,

University of California TV has released a video of a new lecture by Dr Robert Lustig, author of Fat Chance, returning to the theme and location of his original viral video hit “Sugar, The Bitter Truth” for an updated version. It runs for nearly 90 minutes but is highly recommended for his thoughts on sugar, diabetes, obesity, metablic syndrome, leptin, insulin, processed food and much, much more…

Why We Really Eat Too Much

Published on January 21, 2013,

Kate Oliver from the Paleo Works blog has been reading Dr Robert Lustig’s new book ‘Fat Chance’ and says it explains that the urge to over-eat is ultimately triggered by eating too much sugar.  Sugar consumption messes with insulin resistance and this in turn interferes with a hormone called leptin that otherwise tells us we are full. This is from Paleo Works…

Why do we eat too much?

Lack of will power?  Too much TV? Boredom? Problems?

Think again.  According to Dr Robert Lustig the urge to over eat is a hormonal issue triggered by eating too much sugar.

He points to the hunger hormone leptin and its role in our encdocrine system to  suppress appetite.  When we have had enough to eat our fat cells  release leptin which quietens the appetite by sending signals to the brain to tell us we are full.

The problem is sugar.  Our sweet tooth is interfering with the signals, interrupting the signal if you like which is no longer registering the fact in our brain that we are full.  We have become “leptin resistant.”.  We don’t hear the message, we don’t register the signal: no matter how much we eat, we still feel hungry.  Sugar is causing havoc.

What happens next?

We eat.  A lot.  The brain sends out the message for food craving high fat, high sugar food because these give energy fast and have that other powerful pay back : all energy is conserved because all that overeating will keep you sat on the couch.  Sound familiar?  Indeed the food cravings become even more intense (and impossible to resist) because the hormone leptin is supposed to quieten the feeling of pleasure and euphoria we get with certain food by suppressing the release of the feel good brain chemical dopamine.

If we are leptin resistant, it doesn’t happen.  And the cravings continue on and on and on deep into the night. And this, says the Professor is why we find it so difficult to resist.

What causes leptin resistance?  Too much sugar in the diet, says Professor Lustig.  He states that high sugar diets spike hormone response specifically insulin.  This is needed to clear the sugar out of the blood and to transport the excess energy out of the blood stream into storage as…..fat.  Repeated insulin spikes over time cause insulin resistance (diabetes 2) and Professor Lusting states that insulin resistance triggers leptin resistance.

Is it all over?

No.  Professor Lustig has discovered that by reducing insulin levels it is possible to improve the leptin signalling, quieten the food cravings, quieten the overeating and cause weight loss…

Video: Sugar Is Killing Us

Published on October 31, 2012,

This video is from Sugar Is Killing Us - a campaign to spread information about the negative effects of sugar and empower people to make better food choices.

The video cannot be shown at the moment. Please try again later.

The video covers just how much just about everyone loves the taste of sugar but how science is now showing it is actually toxic. It covers obesity, type 2 diabetes and uses statistics on life expectancy to illustrate how the dramatic increase in the amount of fructose we are consuming is damaging our bodies, affecting the role of leptin and insulin and leading to many significant health problems. It also covers high fructose corn syrup and explains that 80% of food items in America now contain added sugar. Finally, it outlines what we can do to reverse this trend.

Please share the video with anyone you know who might be consuming more sugar that is good for them.
