Reset Your Body’s Fat-Burning Clock with Intermittent Fasting

February 3, 2021

The easy, but powerful practice to take weight loss to the next level

Each year it seems that New Year’s resolutions lose their appeal. So instead of deciding to start yet another diet that’s likely to fail, it’s time to set your intentions, and practice a new transformational habit for 2021 – time restricted eating, better known as Intermittent Fasting.

This easy, but powerful practice will not only take your weight loss to the next level, but also boost your immunity, rev up your fat burning metabolism and ramp up your energy levels. It’s a time-tested, well-researched, evergreen practice that has been used for centuries to improve overall health and longevity.

If you’ve followed my New Fat Flush Plan and Radical Metabolism programs and are still struggling to lose weight, then it’s time to “up your game” with intermittent fasting. I’ve found it to be successful for so many of my clients that it’s one of the four highly effective Fat Flush Accelerators that I’ve revealed in my new Ultra Fast Fat Flush Guide

A Change Will Do You Good

Simply put, Intermittent fasting isn’t a diet.

It’s a schedule of eating that doesn’t change what you eat – just when you eat it. It’s as simple as eating all of your food for the day within a time capsule of anywhere from 8 to 12 hours, 2 or 3 days per week. Surveys have shown that most Americans tend to eat over a span of around 15 hours per day. For instance, you may start your day with a smoothie at 7 am, have a snack, lunch and dinner and then munch on something before going to bed around 10 pm or later.

The problem is, our bodies aren’t meant to function that way. We have an internal clock that kicks in with sunrise and begins to close down at sunset. After that, energy producers such as insulin, digestive enzymes, liver enzymes and a host of hormones begin to ebb. Since these substances are needed to burn fat for fuel, eating this way can lead to weight gain, digestive issues, spikes in blood sugar and less than restful sleep.

How Intermittent Fasting Resets Your “Fat Thermostat”

Many of us adjust our thermostats at night by lowering the temperature slightly in our bedrooms for a better night’s sleep. Time Restricted Eating, or Intermittent Fasting, can reset your body’s “fat thermostat” so that you efficiently burn fat as fuel for energy while raising your metabolism. This is achieved by lowering your leptin and insulin levels.

Leptin resistance is the annoying reason why you may lose weight but then have a very difficult time keeping it off. Fat cells are not just storage for excess fat in your body, they are actually components of the endocrine system, manufacturing key metabolic hormones including leptin. In a sense, leptin sets your “fat thermostat”. It normally balances energy, signals satiety, and helps to keep you from accumulating excess fat. The more fat cells you have, the more leptin you make.

Too much leptin produced too quickly can overload your endocrine system. Your brain cells grow resistant to it and proceed to ignore its signals. In a sense, this causes your fat burning thermostat to get stuck, especially if you eat a diet high in unhealthy fats and sugary carbs (including artificial sweeteners). The resulting inflammation triggers more leptin resistance. You’re then trapped in a vicious cycle which can lead to insulin resistance and dysregulation of blood sugar. End result – obesity.

Intermittent fasting can break this cycle, helping you to lose weight and keep it off while boosting your energy levels. One of the ways it does this is by promoting changes on a cellular level due to a substance called adensosine triphosphate (ATP). This organic chemical exists in all living tissue and is uniquely able to harness chemical energy from the breakdown of food. It uses this energy to fuel important cellular activities. Studies have shown that people who participated in time restricted eating experiments had higher levels of ATP in their cells. Throughout their bodies, mitochondria in cells that produce energy were found to be larger and stronger than before. The result was weight loss, increased muscle mass, new strength and more energy.

Why Adrenal Support is Key for Intermittent Fasting Success

Another factor that may play into the vicious cycle of weight gain is adrenal fatigue. Unrelenting stress takes a toll on our eating and sleeping routines. If you find yourself feeling tired, overwhelmed, craving food late at night, or having trouble sleeping, adrenal fatigue may be the culprit. That’s why I recommend UNI KEY Adrenal Formula. It provides natural glandulars and revitalizing nutrients including vitamin C, vitamin A, vitamin B6, pantothenic acid, zinc and tyrosine to promote optimal adrenal function.

Supplementing with adrenal support is especially important if going without food triggers a response for you like reactive hypoglycemia (as it does for me). Personally, I won’t practice intermittent fasting without supplementing with Adrenal Formula. Together, this eating schedule and supplement are a powerful duo to help you achieve slimming success.
