For the report, ConsumerLab.com bought, tested, and analyzed the quality of 17 protein-based products that are used for everything from bodybuilding to weight management. What they found was surprising: some protein powders exceeded limits for lead, contained more carbohydrates or cholesterol than advertised, or less protein than advertised.

A total of five products out of the 17 tested and ConsumerLab.com gave them a “Not Approved” grade—as in “Buyer Beware”. The products were tested to check the accuracy of label claims (total calories, total protein, etc.) as well as possible lead contamination. The products that raised red flags were then sent to another independent lab to confirm the findings.

Of the five products that failed to meet testing requirements, quality problems they had included:

• Less protein than what’s listed: One product actually had 16 fewer grams of protein than listed on the label—that’s almost 70 percent less! Also, the same product had 16 more grams of carbs than listed, including 3 extra grams of sugar.
• Contaminated with lead: One protein-based meal replacement shake had 12.7 micrograms of lead per scoop, which can exceed daily limits (as outlined by U.S. and Health Canada regulatory guidelines) if two or more are consumed daily.
• More cholesterol and calories than what’s listed: One product that claimed to have “0 mg” of cholesterol actually had 10.2 mg. Another product had 25.7 additional calories per serving.

For consumers who are looking to meet health or athletic goals with products like these, it’s easy to see how inaccuracies could be problematic. That’s why it pays to have a company like Isagenix with a “No Compromise” quality policy.

Isagenix products are rigorously tested to be sure they meet label claims. This means that when the label says “24 grams protein,” it’s what you’re getting. Our Isagenix Quality Assurance department performs routine testing of label claim accuracy for the duration of each product’s shelf life, too.

The strict quality policy at Isagenix also involves testing of raw ingredients and finished products for microbial activity, pesticides, and heavy metals including lead, arsenic, mercury, and cadmium. Isagenix uses independent laboratories for testing to guarantee quality and safety.

The process that Isagenix uses for continual inspection of raw materials and analysis of finished products is an expensive enterprise. Because of the high cost of testing, other companies will often cut corners and avoid such extensive testing. At Isagenix we believe that meeting and exceeding safety guidelines is absolutely necessary as integrity and the health of our customers, friends, and family is paramount.

Once again, as evidenced by this latest report from ConsumerLab.com, you just can’t trust every protein powder or drink product you come across.

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’

New research carried out by a group of scientists from the Netherlands reveals that a diet higher than normal in protein may be the key to sustaining permanent weight loss (1). Seventy-two overweight and obese men and women took part in the study, which compared the effects of two reduced-calorie diets after weight was previously lost, the only difference between the diets being that one counted as high protein intake (1.2 grams of protein per kilogram of body weight per day) and the other as normal protein intake (0.8 grams of protein per kilogram of body weight per day). After six months, the group eating more protein was found to retain greater muscle mass and a higher rate of metabolism, helping to better keep that lost weight from returning.

Previous studies investigating the effect of energy-restricted, high protein diets on weight maintenance have reached similar conclusions (2). The fat-fighting power of protein lies in its ability to keep energy expenditure elevated as well as curb hunger despite reduced calorie intake.

Rev Up Your Metabolism with Protein

Energy expenditure, or the number of calories burned by the body, is greatly influenced by basal metabolic rate (BMR), which is the amount of energy, or rate of metabolism, required to support basic body functions when your body is at rest.

The greatest contributor to BMR is fat-free mass. Fat-free mass is largely made up of muscle, which is very energy demanding. Even when no work is being performed (such as when you are sleeping), muscle requires energy just to exist. Muscle cells and their components are constantly using calories to rebuild what is broken down during normal protein turnover. A higher protein diet not only increases energy-demanding protein synthesis and turnover, but has also shown to better preserve muscle during caloric restriction (1, 2). Keeping muscle mass and turnover rates high results in a higher BMR, faster metabolism, and greater energy expenditure.

The thermic effect of food (TEF) is another factor that affects energy expenditure and refers to the amount of energy needed to break down, absorb, and digest food. The TEF differs between nutrients, with protein requiring more calories for digestion and metabolism than both fat and carbohydrate combined. Specifically, 0 to 3 percent of the calories obtained from fat are used for fat digestion, 5 to 10 percent of calories from carbohydrate are used for carbohydrate digestion, and 20 to30 percent of calories from protein are used for protein digestion (2). This means that protein requires a substantial amount of calories for the body to metabolize and use it compared to the other macronutrients. Simply by eating more protein in place of carbohydrate or fat, a person will burn more calories.

Feel Fuller, Longer with Protein

Successfully committing to a reduced calorie diet can be difficult when you are bombarded by cravings and hunger pangs. Ravenous hunger will only encourage overeating and weight regain. Research has shown higher protein diets to be superior to low or standard protein diets in causing a feeling of fullness, thereby leading to lower calorie intake (2). A reduced calorie diet will lead to greater use of existing fat stores, as a person quickly burns through the energy provided by the food they consume, as well as the carbohydrate stored in the body (glycogen). This increased reliance on fat for fuel has been suggested to reduce appetite.

Protein may also boost satiety by sending hormonal messages to the brain signaling fullness. When protein is eaten, sensors located in the gut are activated. Hormones such as glucagon are released, sending a message to the brain saying, “I’m full!” (3).
