What is a Fitness Plateau? How can break through it?

Plateaus of Weight Loss- Adaptive Thermogenesis  

Research done by Mike Roussell PhD 

Plateaus can be frustrating and detrimental to your fat loss if not dealt with swiftly and properly. Another way to look at weight loss plateaus is that they are actually your body settling in at a new body weight set point.

The set point theory is basically the idea that your body likes to be at a certain body weight and it will work to keep you there. Chances are you have experienced this in your own life. I’m talking about situations where you will gain or lose weight but inevitably after a couple weeks or months of trying to change you end up around the same body weight.

In order to break these body weight set points, it is important to understand the forces that you are working against (know thy enemy, right?). I’m talking about adaptive thermogenesis.

Adaptive thermogenesis is the seemingly automatic reduction in energy expenditure that occurs when you diet. Many think that this is the driving force behind people’s body weight set point.
This is important so I want to make sure I’m explaining it clear enough so here’s an oversimplified example.

You are currently eating 2000 kcal per day. Your body is currently burning 2000 kcal per day. You decided that you need to lose weight so you cut 500 kcal from your diet. So in theory your body should now have to dig up another 500 kcal from body fat to fuel the calorie difference???

EXCEPT ->>
It doesn’t work that way. Studies show that your body adjusts its energy output so that it can now function on only 1500 kcal per day. This is adaptive thermogenesis. It has been demonstrated that adaptive thermogenesis occurs with both severe and modest calorie cutting.

What is the driving force behind this? Here are some candidates:

• Changes in body weight
• Changes in Leptin
• Changes in Insulin
• Changes in Thyroid Hormones
• Depletion of Fat Stores

 Fortunately you can beat all of these, prevent adaptive thermogenesis, and keep the weight loss coming.

The answer?

Metabolic Training combined with diet.

We know from research and anecdotal evidence that not all exercise prescriptions work. What does work is intense metabolic resistance training...think HIIT and Tabata!

If you are currently stuck at a weight loss plateau, you need to break your body’s set point. To do this it is necessary to undergo a rigorous change in diet and training so that you can in essence shock your system.

Here’s what to do next. Once you break though your sticking weight, maintenance is very important. Get 5-15lbs below your old body weight set point and maintain that weight. Many people lose their fire and drive after they have lost the weight but you need to stay focused so that you can reset your body’s set point.

Maintain your new weight for 4 weeks (this is ideal) before you start losing weight again. This step wise approach will help reset your system to your new body weight and help fight its urge to return to the old set point. The key is keeping your body weight long enough so that your body ‘thinks’ that is the new normal.

Stay Focused and Invest in the Long Term - you'll get there!
