First and foremost it is important to point out that protein shakes themselves are not magical elixirs that will miraculously cause weight loss. However, if correctly implemented into a balanced diet alongside an effective exercise regime, ideally involving resistance training, protein shakes can indeed aid in weight loss.
A major property of protein which makes it a good weight loss tool is its filling effect or ‘satiating power’. Carbohydrate, fat (lipids) and protein are the three macronutrients. They are the components of our diets that are needed in large amounts as they provide energy to fuel chemical reactions (metabolism), growth and other essential functions. It has been clinically proven that of the three macronutrients, protein is the most satiable. It is this quality that makes it an effective weight loss tool.
How to lose weight with the aid of protein shakes
Consuming a protein shake in between meals can prevent you from overeating as you should feel fuller for longer. You are therefore likely to consume fewer calories over the course of the day. As is commonly known, in order for weight loss to occur the number of calories consumed must be lower than the number of calories spent. Additionally, if you have chosen a good quality protein shake which does not contain added sugars, you will avoid spikes in your blood sugar levels. Often with snacking it is easy to reach for a sugary or fatty food without much thought. Even if the food is low in calories, the resulting sugar spike will leave you craving more sugary foods, and perhaps consuming more. This will eventually lead to a calorie surplus, and over a period of time, weight gain. One such protein supplement that has the necessary ingredients to help you achieve weight loss when used as a meal replacement is Kinetica Whey protein.
Bearing this is mind, careful consideration is required when selecting a protein shake to supplement your diet.
When selecting a protein powder in order to aid your weight loss, a protein powder containing a large quantity of whey protein isolate would be ideal. Whey protein isolates are the purest form of whey protein and are have a high thermic effect. Foods with a high thermic effect require more energy to process, therefore using up more calories than foods with a low thermic effect. In addition, whey protein is effective in stimulating muscle protein synthesis.
One of the most popular protein powders of today is Optimum Nutrition Gold Standard 100% Whey protein powder. It is a high-quality protein powder containing whey protein isolates and has been voted Protein Powder of the Year in the annual BodyBuilding.com supplement awards on numerous occasions.
