Leptin | Reset Leptin Levels and “Turn On” Fat Loss

August 12, 2013 by Shaun Hadsall 1 Comment

Leptin Levels | Reset Them:

I came across this remarkable study a while back and I wanted to make sure
you’re using this trick at least a few times a week so you can reap the benefits.

This is some pretty powerful stuff that will help you with both your long term
health and fat-burning hormones.

Now many of you already know I’ve been going against the grain and advocating
high intensity fasted training for over 15 years.

But before I reveal the findings of this research, I want to go on record by saying
there is strong research that supports both camps when it comes to the “fasted vs. fed” exercise debate.

Ultimately you have to figure out what works best for you personally through trial and error.

Since I’ve pretty much stayed under 10% body fat since 1998 using high intensity
fasted training (without losing muscle), you can probably see why I lean this way – heavily.

However, I know many folks (including a select few of my own private clients) that
get great results exercising in more of a “fed” state.

But the majority of the time fasted training done correctly “trumps” the results of
training in a fed state – especially when it comes to hormones and burning stubborn fat.

Ok, enough of my rant…let’s get to the study.

This is a GREAT way for you to take control and understand your #1 fat-loss
hormone, leptin, so make sure you read this article all the way through.

First, here’s a short crash course on Leptin.

leptin
Leptin Hormones “Turn On” Fat-Burning Switch

Leptin is released primarily by fat cells and works to regulate appetite, body fat
mass, and basal metabolic rate (BMR).

This indicates that fat cells are very metabolically active.

So unlike previously thought, fat cells release and receive a variety of different hormonal signals from things like leptin.

The more body fat you carry, the more leptin you’ll have and vice-versa. The leaner
you are, the less leptin you’ll have.

That’s one of the many reasons it’s so easy for an obese person to peel off the pounds
fast and why leaner individuals have a hard time burning off that last few pounds.

Here’s How You Can Reset Leptin and “Turn On” Fat-Loss In Only 30 Seconds…(Whether You’re Skinny OR Fat).

You already know that I’m a huge advocate of sprint-burst type training as a greatway to burn fat, but it actually may have another benefit.

A study done by Guerra et al. in 2011 looked at sprints and their effect on leptin “signaling.”

This study also used a group of individuals who were pretty lean (about 15% body fat).

They split them into two groups:

GROUP 1: Fasted

GROUP 2: Fed

So Group 1 had an empty stomach and Group 2, considered the glucose group, ingested 75 grams of glucose one hour before sprints.

Both groups performed ONE Wingate bike sprint for only 30 seconds.

What Happened…?

Researchers found that a SINGLE session of sprint training had powerful effects
on leptin “signaling” in the fasted group.

The sprints reset leptin levels that should help overweight and obese people burn
MORE fat and help already lean individuals get “leaner.”

However, this was NOT seen in the group that consumed the glucose before their sprint. Only the fasted group saw leptin signaling be “reset.”

This indicates (but doesn’t necessarily prove) that insulin may interfere with the
leptin signaling to some degree.

Here’s what the researchers said about the study:

“Altogether, these results indicate that sprint exercise performed under fasting conditions elicits signaling events similar to those described in the rodent skeletal muscle after leptin injections, i.e. sprint exercise under fasting conditions acts as a leptin signaling mimetic in human muscle. However, glucose ingestion before
the sprint training exercise blunts this effect.”
(Guerra et al. 2011)

This is the same thing I’ve been saying for years.

Eating food and consuming calories before exercise is a “healthy” choice,
but it can end up blocking the release of powerful fat-burning hormones.

This study basically shows that fasted burst-sprint type training can serve as a legitimate way to control leptin and ultimately help you control long term fat loss.

Chalk another one up to fasted burst-sprint type of training!

Not to mention all the other benefits of high intensity fasted training you’ve probably heard me preach about a thousand times.

Increased adrenaline (which are catalyst to break up stubborn fat), Growth Hormone (the one that keeps you looking younger), and lower blood glucose and insulin…

…ALL which leads to increased fat-loss.

While the study didn’t look at running (sprinting) or using bodyweight circuits…it will elicit the same response.

After all, the pathways are pretty much identical.

Fasted bursting, sprints or bodyweight circuits can be done any time on an
intermittent fasting day, before breakfast or even 3.5 to 4 hours AFTER a meal.

Of course, NONE of this is easy…it will require effort.

But at least this study shows you exactly how to get more bang for your buck.

Now you just have to combine it with a nutrition plan that you KNOW you can stick to for the long haul.

The ONE Day Diet is, by far, one of the easiest nutrition plans on the planet and its set up to work perfectly with this trick.

If you’re looking for fat-burning nutrition simplicity…

THIS is your ticket.

You’ll even get a *free* meal plan to follow:

Have a great day.

    Just curious. If I do a fasted 30 sec row sprint in the morning, would I continue with a fasted morning being that if I eat, insulin would necessarily rise (to what degree depending on the sugar intake). Would that negate the process, or could I just continue with my regular nutrition plan for the day because the sprint was designed to increase leptin sensitivity, not necessarily to act as a fat burning concept in the hours following the sprint??????

    Thank you.
