Weight Loss
Weight loss has certainly become “big business” over the last few years. The amount of money spent on exercise equipment, diets and weight loss programs is steadily climbing. Today, weight loss is such a high profile subject that new research is coming out on a daily basis. However it is always worth finding out who has funded the research, as an impartial approach is essential if we are to receive a truthful outcome. I’m sure you are aware of the fact that sometimes research can be very biased depending on who does and most importantly who pays for it.
Health related industries and professionals are constantly experimenting to find out the best way for us to maintain a healthy weight. Recently research has found that with all three macronutrients – protein, carbs or fat – daily calorie intake was significantly greater when the beverage form was consumed as compared to the solid. Apparently the protein drinks did not satisfy the appetite the way that protein foods did! So weight loss is not necessary guaranteed with these liquids meal replacements.
This particular finding was a surprise for many who work in the weight loss industry. It was thought that protein drinks would be an effective part of a weight loss regime, mainly because protein foods have been proven to reduce appetite and increase satiety. However if you convert solid protein into a protein drink, it loses it’s appetite suppressive properties. A similar thing happens when you turn fruit into fruit juice.
Many people are not aware of the findings related to these protein meal replacement drinks. Most time people just hear what these companies want us to hear through their mass media campaigns. Looking at the available research, there are at least 7 scientific studies that have provided strong evidence that energy containing beverages (i.e., “liquid calories”) do not properly activate the satiety mechanisms in the body and brain and do not satisfy the appetite as well as food in solid form. Having tried them myself I can vouch for the fact that the drinks left me with a feeling of just being full of liquid. Not satisfying at all. However if I mixed the powder with a food such as yoghurt and a banana, the satiety value increased significantly and I did go on to lose weight.
I have done some research on my own and found out the following facts related to the lack of satiety value of the liquid calories:
1. high calorie density
2. lower satiety value
3. more calories ingested in short period of time
4. lower demand for oral processing
5. shorter gastrointestinal transit times
6. energy in beverages has greater bioaccessibility and bioavailability
7. mechanisms may include cognitive, orosensory, digestive, metabolic, endocrine and neural influences ( proving that the human appetite is a complex thing!!!)
8. last but not least, nowhere in our history have our ancestors had access to large amounts of liquid calories, even of the protein variety.
As strange as it may seem, our bodies cannot properly register the caloric content in liquids the way we do when we eat, chew and swallow whole foods. As with many “nouveau foods” that appear on our supermarket shelves, our genetic code has never developed the physiological mechanisms needed to deal with these foods. Bottom line: This study suggests that if you’re trying to beat body fat,(weight loss) it’s wise to limit all types of liquid calories and eat whole foods as much as possible, so that the body can process the food in the best way it knows how.
What liquids we drink are an important part of any weight loss program. With regard to liquid beverages apart from the protein drinks, if you really want to achieve successful weight loss, start by removing the soda and other fizzy drinks from your diet. Then get rid of the high calorie dessert coffees. Apart from anything else coffee plays havoc with your metabolism. Then cut back on the alcohol, another high calorie stimulant that your body can well do without. From there, be cautious even about milk, juice and especially protein drinks, that may be the mainstay of your weight loss diet. Drink water or herb teas instead, or limited amounts of black coffee or tea – without all the high calorie extras.
Knowing the amount of calories in the foods and drinks we consume is a very important, yet tedious, part of our attempts at weight loss. It is worth remembering that if you do consume any beverages that contain calories, such as protein shakes, be sure to account for those calories meticulously and be sure you don’t drink them in addition to your usual food intake, but in place of an equal amount of food calories. Protein shakes are intended to be “meal replacements” not “free calories!”
One of the main goals in any weight loss program has to be a change in our eating habits, as this most likely is the reason we have put on the extra weight. As your weight loss program is about reprogramming your dietary habits, it would be far better if you concentrated on eating proper food that is chosen for its health promoting properties rather than supplementing or replacing your healthy food with a liquid diet
