Current Diets Under the Microscope
Too often, many people turn to various “miracle” solutions with the intention of speeding up their weight loss process. I agree that the promise of a quick and safe weight loss solution is attractive. But at what price? Keep in mind that “quick” and “safe” rarely go together. A safe weight loss equals to a rhythm of around 1 kg or less per week, unless there is strict monitoring from a professional team (nutritionist, kinesiologist or other recognized professional in the field of physical activity, doctor).
Lately, we have heard a lot about Visalus and their “Body by vii” challenge, as well as from other companies such as Usana, Slimfast, Herbalife, or others, each with their own quick weight loss formula. They make various claims, such as recovery from many illnesses, an increase in energy levels, as well as a quick weight loss of course. In truth, regardless of the nutrition method used, a loss of 5 to 10 % of a person’s extra weight (for example: a 170 lb person that would lose 8.5 to 17 lb) is enough to improve many health parameters, such as a reduction of blood pressure, of blood sugar on an empty stomach, of pain in lower limbs, etc. Therefore it cannot be attributed to the product itself.
These diets all use the same principle: replacing meals with shakes (one to two a day), and snacks are also provided by the company (chocolate cookies, protein bars, chocolate pudding, etc.).
During the duration of the weight loss program, it is strongly recommended that you take a multivitamin as well as a supplement of omega-3. They are aware of the fact that by feeding on their products, you will develop multiple nutritional deficiencies.
What should we think of this?
· No nutritional evaluation is performed; therefore, the diet will not be adapted to your lifestyle and level of physical activity.
· The protein intake provided by these diets can often be double, even triple than the needs of the individuals. A protein intake that is too high can put a lot of work on the kidneys, which needs to eliminate the amino acids surplus. In addition, in the long term it can lead to a feeling of tiredness, since the absorption of such a quantity of proteins requires a lot of energy from the body.
· These weight loss formulas help you treat a symptom, which is extra weight, without treating the cause: you get no help in finding out why you are overweight in the first place.
· You are not taught hot to plan your nutrition and prepare healthy and balanced meals according to your reality (working on the road, having four kids, a spouse allergic to something, working night shifts, etc.).
