Notice a surge in your food cravings? You may want to check your bedtime. In the first laboratory study of its kind, researchers from the University of Pennsylvania showed that otherwise healthy people who stay up late and don’t get a good night’s sleep are likely to gain weight from indulging in fattier foods during the late-night hours.

In the study, published in the journal Sleep, 225 non-obese people between the ages of 22 and 50 were randomized into a sleep restriction group or control group for 5 nights—the sleep restricted group slept from 4 a.m. to 8 a.m. while the control group slept from 10 p.m. to 8 a.m.

It’s 11 p.m. and you’ve just scarfed down a slice of leftover pizza and a few too many Oreo cookies. The satisfying taste of salty and sweet is quickly overcome by guilt, frustration, and what is now an uncomfortably full belly. After eating balanced meals and healthy snacks all day, you are defeated by your late-night craving for junk food.

How can you avoid this self-defeating debacle? New research shows that eating a high-protein breakfast is the best way to avoid those p.m. cravings.

A study from the University of Missouri-Columbia showed that subjects who ate a high-protein breakfast had increased levels of satiety along with reductions in brain activity responsible for controlling food cravings that lasted into the evening.

Cleansing is one of the many reasons that Isagenix systems are different from other “diets”. In fact, diet is really the wrong word to use to describe Isagenix. We offer a collection of systems that can be customized to your own health goals and adopted as a lifestyle, meaning these are habits and tools you’ll have for the long haul. Cleansing is one of those habits within an Isagenix lifestyle.

Isagenix has been leading the way to health by advocating the practice of cleansing for more than a decade. Now, recent scientific findings are leading nutritional researchers to believe that this practice of “cleansing”—a combination of intermittent fasting with herbs and vitamins that support detoxification—provides surprising health benefits.

You know how it is with regular dieting—your long-lost skinny jeans make a temporary reappearance only to be retired to the back of your closet six months later. This frustrating scenario of weight cycling is all too familiar for most people.

Although decreased motivation and will-power greatly contribute to “falling off the wagon”, weight regain is also influenced by biological changes in the body in response to decreased intake of energy or calories. The main biological reason for weight regain is a slowing metabolism. A reduction in calorie intake can make the body become very efficient and work to conserve energy. Unfortunately, this means you are burning fewer calories. Loss of lean tissue (such as muscle) rather than fat mass during weight loss is also to blame for a lower metabolic rate (more on this below).

In a world where yo-yo dieting has become the norm, how does one keep lost pounds off for good?

It may sound cliché, but the best of the best just keeps getting better. And, it’s true for IsaLean Shake with the introduction of Creamy French Vanilla and Creamy Dutch Chocolate flavors.

Calorie for calorie, each serving of the new shake flavors unleashes a tidal wave of nutrients designed to flood the body’s cells with what they need to thrive, build quality tissues, strengthen muscles and bones, and battle oxidative stress.

How is it possible? What’s different? And, why are these shakes even better for fighting fat and getting leaner? Here are seven reasons, based on the latest nutritional science has to offer, that make the new shakes more nutritious than ever:

When most people think of a “cleanse,” they envision uncontrollable trips to the bathroom, gag-provoking concoctions, and absurd food restrictions. Fortunately, with Isagenix Cleanse Days, you can get all the health benefits of nutritional cleansing without experiencing those horrific—and sometimes dangerous—situations.

What makes Isagenix Cleanse Days different? The combination of decreased calorie intake with the herbs, vitamins, and minerals found in tasty Cleanse for Life supports the body nutritionally while giving the digestive system a chance to rest and the body a chance to detoxify. Unlike other “cleanses,” Isagenix Cleanse Days do not involve restricting yourself to drinking plain juices, or worse, taking laxatives, which can often do more harm than good.

If there had been an award for “Most Valuable Nutrient” of the decade, vitamin D would without a doubt be a front-runner. Every tissue and cell in the body has a vitamin D receptor, signifying its importance in everything from bone health to brain health.

Unfortunately, it’s been estimated (1) that 20 to 100 percent of U.S., Canadian, and European elderly men and women are deficient in the “sunshine vitamin”—appropriately named since it can be produced by the body when exposed to direct sunlight. While research has focused on lack of sun exposure (especially during the winter months) as a reason for vitamin D deficiency, a new player may be to blame—obesity.

In a recent study with over 42,000 people from 21 countries, researchers found a significant link between high body mass index (BMI) and low vitamin D levels (2). In fact, for each 10 percent increase in BMI there was a 4.2 percent drop in vitamin D.

We have all experienced it before. Your New Year’s Resolution to eat healthier starts off strong, but it’s not long before for a small “cheat day” here and there turns into every day being a cheat day. If you really want to make a change in your diet, resolve to use Isagenix for 66 days. Why 66 days? Science shows that is how long it takes to create a new habit.

A study published in the European Journal of Social Psychology investigated the key factors in creating and breaking habits and how we can set ourselves up for new patterns of behavior. The study included 96 subjects who chose an eating, drinking, or activity behavior to carry out daily for 12 weeks. During the study, subjects completed self-report surveys which indicated whether or not the behavior was carried out daily and level of difficulty to perform the new habit.
