For the health-minded individual, two protein choices seem likely candidates for dietary supplements, but the choice between soy or whey protein for weight loss must be made according to the needs of the individual. Each of these types of protein supplements offers unique advantages, but for those people who are vegan or allergic either to soy or to whey the choice is more crucial.

Soy Protein-The Vegetable-Based Alternative

Soy protein is derived from soy bean flour. As such, it is a vegetable supplement that can provide the necessary daily requirements and the protein boost needed for specific weight loss regimens without loading the individual's diet with meat products. Soy beans are naturally low in carbohydrates (carbs) and provide high protein levels. Unlike all other vegetables, soy beans actually have fewer carbs and more protein. Because soy is low in carbs and fat, soy protein's glycemic index is low as well. This means that taking a soy protein supplement reduces your risk of producing too much insulin, which occurs when your body perceives the necessity to store sugar for fat in your blood. For this reason, soy protein is an ideal supplement for individuals hoping to lose weight. Additionally, as a source of both essential and nonessential amino acids, soy protein can be used to help build lean muscle and supply much needed energy to low-calorie diets.

Amino acids are the building blocks of protein, but the human body cannot produce its own essential amino acids. This makes it necessary for essential amino acids to be supplied by a healthy food source or supplement. Easy to take and easy to digest, soy protein is an excellent source for essential amino acids. In fact, soy protein is considered the world's only complete vegetable-based protein as it supplies all 9 of the essential amino acids that your body requires. The individual who uses a soy protein supplement will have all of his/her essential amino acids with less fat and fewer calories than meat protein delivers.

Available in powders and capsules, soy protein requires no added talents or tools for consumption. Many people rely on healthy, great-tasting soy shakes to deliver all the protein they need to stay fit and healthy. Studies show that soy protein leaves its users feeling full longer. There is evidence that soy consumption actually causes the brain to deliver a "Tummy Full" message to the body, making it easier to consume fewer calories and to reach desired weight levels.

It is possible to be allergic to soy beans or soy bean products. Individuals who feel they may be allergic to soy in any form should avoid using a soy protein supplement. Other supplements are available, and-indeed-whey protein may be a better choice for soy-allergic individuals.

Whey Protein-The Dairy-Based Alternative

Unlike soy, whey protein is derived from an animal source-milk. For individual's seeking an alternative to full meat protein without giving up body proteins completely, whey protein can be used as a dietary supplement. The benefits of whey protein are many. It is believed to curb hunger, control weight, control glucose absorption, and boost immunities.

All proteins require great amounts of energy for digestion. This energy translates to calories. As the body uses calories to digest the proteins consumed, weight loss diets are boosted. The body actually loses more weight than it would have lost burning other types of digestibles. As an excellent source of essential amino acids, whey protein stimulates calorie burning digestion as it preserves lean muscle tissue. The human body requires amino acids, and when those essential amino acids are no longer available through dietary supplement, the body naturally robs the muscle tissue to gain them. Taking a whey protein supplement will not only protect muscle reserves of amino acid, but it will also stimulate production of lean muscle tissue through the supply of those essential amino acids.

Whey protein's benefits as a weight loss supplement are further proven as it provides glycomacropeptide (GMP) which stimulates the body's production of CGK, a hormone useful in appetite suppression. In addition to stimulating CGK production, whey protein also stimulates formation of the anti-oxidant glutathione. Glutathione boosts the immune system naturally, making whey protein an excellent dietary source for people prone to illness, of advanced age, susceptible to infection, or who smoke tobacco.

While whey protein is an excellent supplement for various diets and can be useful in weight loss regimens, it is not suggested for individuals who are allergic to dairy products, lactose intolerant, or seeking a vegan lifestyle. As a milk-source product, whey is likely to cause discomfort for people who are allergic/lactose intolerant and should be considered a dairy product unfit for a vegan way of life.
