What’s a Complete Meal Replacement?

A Beginner’s Guide to the Low-Glycemic Diet

Liquid meal replacements in a can or a bottle are easy to transport; no preparation or clean-up is required, and some products need no refrigeration. There's research to suggest that the monotony of consuming the same type of meal replacement with a similar texture each day leads to "sensory-specific satiety," ie, the decreasing pleasure of tasting, smelling, or eating a food until full or satisfied.

Disadvantages Liquid meal replacements often are short on fiber and don't provide all of the phytochemicals found in plant-based foods. Crandall notes that one of the downsides to liquid meal replacements is that for some the transition to real food can be especially difficult. A critical aspect of long-term weight management is education—learning to estimate portion sizes of real foods and translating that knowledge into smaller serving sizes for meals and snacks.

Unless a strong support system is provided, she says, that won't be a part of the learning curve and problems can occur when real food is reintroduced, especially if liquid meal replacements are the sole source of nutrition. Some liquid meal replacements contain sugar alcohols, which can cause bloating and diarrhea in some individuals.

Some contain artificial sweeteners, which may be a deal-breaker for certain clients. In addition, liquid meal replacements can be expensive, depending on how many are consumed daily. If one drink simply replaces breakfast, cost is unlikely to be an issue.

Even a very low-calorie diet to kcal per day would require three to five meal replacements per day. What the Research Says Many studies that have been designed to evaluate the efficacy of meal replacements for weight loss and determine whether they improve health parameters have been sponsored by companies that sell meal replacements or written by their employees or consultants. But not everyone sees that as a problem. We should take a bit of time to review the research and come to our own conclusions.

It's difficult to assess the benefits of the liquid meal replacements used solely as nutritional supplements rather than for weight loss or blood sugar control.

But these products can help increase nutrient intake when appetite is low, when recovering from an illness, when swallowing is difficult, or when weight gain is the goal. The bulk of the research in this area has focused on liquid meal replacements for weight loss, and these products have shown advantages over self-selective weight-loss diets for some individuals.

A meta-analysis of six randomized controlled trials of at least three months in duration and designed to examine the weight loss efficacy of meal replacements, including liquid meal replacements, when food at one or two meals was provided as a meal replacement, found that subjects experienced significant improvements in glucose, insulin, triglycerides, LDL cholesterol, and systolic blood pressure.

While the ideal is to develop a dietary plan based on only real foods, an expert workshop on the topic of liquid meal replacements concluded that conventional dietary treatment for weight loss and weight maintenance in patients with type 2 diabetes might be improved by a meal replacement strategy that offers a structured meal plan with dietary variety.

If it's determined that a liquid meal replacement is a workable option for a client or patient with diabetes, it's important to bear in mind the sugar content of these products. Experts have expressed concern about the use of liquid meal replacements in treating obese patients with type 2 diabetes because of the sugar content of some of the products. There also were reductions in insulin and hemoglobin A1c. A six-week study found that even over a short period of time, a meal replacement was more effective than a fat-restricted, low-calorie diet in reducing metabolic risk factors, insulin, and improving anthropometric measures.

Recommendations Despite these positive study results, it all comes down to screening clients and patients and deciding what's appropriate for them, Crandall says. She works with a team of dietitians and says that with each client they must decide whether it's better to counsel him or her on healthful eating and lifestyle habits from the start or whether a liquid meal replacement will work well in the beginning.

She says she was surprised to find that clients really enjoy the products. It removes the burden of deciding what to eat. Crandall also notes that using liquid meal replacements on a very low-calorie diet works best if there's a strong support team that includes a dietitian, a psychologist, and a physician. Given the right match with the client, these products can be effective, she says. The American Diabetes Association has stated that the use of meal replacements once or twice per day in place of the usual meal can result in significant weight loss.

However, Craig says that cost is an important factor. Ingredients in liquid meal replacements vary greatly. Until almost every product found in this supplement category comprised the " ECA stack ": However, on February 6, the Food and Drug Administration FDA banned the sale of ephedra and its alkaloid , ephedrine, for use in weight loss formulas. Several manufacturers replaced the ephedra component of the "ECA" stack with bitter orange or citrus aurantium containing synephrine instead of the ephedrine.

Experimental models, fatty infiltrations, and prevention". In conclusion, HMB treatment clearly appears to be a safe potent strategy against sarcopenia, and more generally against muscle wasting, because HMB improves muscle mass, muscle strength, and physical performance.

It seems that HMB is able to act on three of the four major mechanisms involved in muscle deconditioning protein turnover, apoptosis, and the regenerative process , whereas it is hypothesized to strongly affect the fourth mitochondrial dynamics and functions.

For all these reasons, HMB should be routinely used in muscle-wasting conditions especially in aged people. HMB, a derivative of leucine, prevents muscle damage and increases muscle strength by reducing exercise-induced proteolysis in muscles and also helps in increasing lean body mass.

The meta analysis studies and the individual studies conducted support the use of HMB as an effective aid to increase body strength, body composition, and to prevent muscle damage during resistance training.
