Applied Nutrition Diet Whey
Diet Whey is a product from UK based company Applied Nutrition. This product states that it can be used as a simple method for weight management; although this description is pretty vague,this review will aim to examine the ingredients in this product to see if it can support the claims made.
Whey Protein Blend (Milk) (95%) (Whey Protein Concentrate & Whey Protein Isolate)
Whey protein helps aid muscle protein synthesis when combined with resistance training (1, 2). Other key features include increasing muscle mass (3), an increase in lean body mass (4) and greater recovery from exercise (5). Longer periods of supplementation have shown greater gains in fat free mass (6).
Muscle protein synthesis is increased due to high concentration of Leucine (BCAA) which is a signalling molecule needed to increase muscle protein synthesis (7). Consumption of whey protein helps increase muscle mass due to a greater amount of peripheral nitrogen retention whereas soy protein has been found to have a greater effect on splanchnic protein synthesis (8).
The reason for greater recovery of exercise can be due to a post exercise insulin response (9, 10) which means glycogen resynthesis occurs rapidly so exercise can be prolonged, with greater training volume increased hypertrophy and decreased muscle damage.
Conjugated Linoleic Acid (CLA) has been shown to have weight loss properties (11); there are several reasons for this which includes an increase in energy metabolism (12), insulin resistance (13), stimulation of lipolysis, which is due to an impaired signalling which reduces triglyceride synthesis and releases free fatty acid which normally occurs when energy demand rises (14). Other mechanisms include a suppression of appetite (15), induced adipocyte apoptosis which decreases body fat mass and increased energy expenditure (16).
L-Carnitine is a dipeptide made from the essential amino acids lysine and methionine. L-Carnitine plays an important role in fat metabolism by allowing long chained fatty acids to pass through the mitochondrial membrane (17, 18).
Green Tea Extract
Green tea supplementation has been shown to have several health properties including an increase in plasma antioxidant which will lead to a lowering of oxidative damage (19, 20), decreased blood pressure (21, 22) and it can protect against coronary atherosclerosis (23). Other health effects that green tea can have includes a lowering of cholesterol, an increase of insulin activity (24) and a regulation of blood glucose levels which can help reduce body fat.
Sweeteners (Sucralose, Stevia).
Sucralose is a sweetener that is calorie free. This ingredient is used in many products and is used to make the product taste sweeter and does not have any nutritional benefit.
Stevia does not have any nutritional benefits as it is a sweetener and sugar substitute extracted from the leaves of the plant species Stevia rebaudiana
