The Role of Soy Protein and Weight Reduction
Soy Protein: High Quality Protein
Calorie-restricted diets require adequate, high quality protein for muscle repair and synthesis and lean muscle tissue maintenance. Various findings show that well processed soy protein isolates and concentrates can serve as the major or even sole source of protein intake and that their protein values are essentially equivalent to that of foods of animal protein (Young, 1991).

Soybeans are the only vegetable that contains complete protein. Soybean protein provides all eight essential amino acids in the amounts needed for human health. Additionally, the amino acid profile of soy protein is essentially equivalent in protein quality to that of milk, meat and egg protein.


Soy Protein and Weight Loss
Soy protein contains all eight essential amino acids. It is also higher in non-essential amino acids than the majority of animal proteins. Some researchers feel that proteins higher in non-essential amino acids should preferentially favor glucagon production (fat burning) and decrease insulin secretion (McCarthy, 1999). Moreover, protein from legumes (soy and others) may be more slowly absorbed, as compared to animal protein. (McCarthy, 2000). In single meal tests, protein exhibited a greater thermogenic (heat producing) and satiating effect than carbohydrate (Mikkelsen et al., 2000). This means that soy protein produces a larger calorie expenditure than carbohydrate. In fact, substitution of carbohydrate with 17-18% of energy as either pork-meat or soy protein produced a 3% higher 24- hour energy expenditure, which may serve as a preventative measure in the treatment of obesity (Mikkelsen et al.,2000).

Isolated soy protein provokes a greater release of the hormone glucagon. Glucagon is responsible for the obstruction of fat storing enzymes and increasing fat metabolism (fat burning). It is also responsible for decreasing cholesterol synthesis (production). Thus, diets featuring vegan (plant) proteins can be expected to lower elevated serum lipid levels (triglycerides and cholesterol), and promote weight loss. Bosello et al, (1988), Jenkins et al (1989), McCarthy (1999).

Weight loss, especially when seen from very low calorie diets, promotes fat and lean muscle tissue loss. Researchers have reported increases in lean body mass in peri-menopausal (before menopause) women when soy protein and not animal protein was used as the dietary source of protein. (Moeller et al, 2000). Animal studies have also shown the beneficial effects of soy protein on weight reduction. (Arjmandi et al., 1996).

In another animal study by Aoyama et al (2000), weight and body fat reduction in rats and mice subjects was more dramatic when fed a diet of soy protein isolate compared to those fed a casein-based diet. It was concluded that these results indicate that soy protein isolate is a suitable protein source in an energy-restricted diet for treating obesity.

Soy Protein: Improved Glucose Control
Soy protein and its many bioactive components may play a beneficial role in obesity and diabetes. Small, short-term human and animal studies with obese, diabetic and non-diabetic subjects have shown positive effects on weight loss, and reduction in blood lipids, insulin and insulin resistance (Bhathena et al, 2002). In a study by Aoyama et al (2000), rats fed a diet of soy protein had lower plasma glucose levels than those fed the casein diets. It is not clear which component of soy is responsible for these effects. However, it appears that soy and its bioactive components may help to regulate insulin secretion.
