Losing weight requires a change in lifestyle that includes a restriction on the number of calories consumed and increasing physical activity. This often turn to diet plans too far from our food habits. The Mediterranean diet is the food that kept for several centuries the peoples of the Mediterranean seashore.

The Mediterranean diet is not uniform because there are several countries who enjoy it, giving each their peculiarities. But yes there are a number of characteristics common to all which can be summarized in a moderate intake of fat, olive oil as the main source of fat, high consumption of foods high in fiber (vegetables, fruits, vegetables ), fish and poultry as an important source of protein. As this is an eating pattern characteristic of our environment, one may ask: Eating a Mediterranean diet is a good strategy to lose weight?

Dr. Shai and colleagues have addressed this issue. This compared the evolution of body weight in three groups of patients. One, following a Mediterranean diet, another a diet low in carbohydrates (like the popular Atkins diet), and the other group a diet based on restricting the number of calories from fat. All followed the same type of diet for 24 months. Patients lost weight with the three types of diet. However, weight loss was greater with the Mediterranean diet and the low-carbohydrate versus low fat diet. Furthermore, those who formed the treatment group followed a Mediterranean diet better diet than those assigned to a diet low in carbohydrates.

Two years later, the weight loss was approximately 4.5 kg in the two most effective types of diet. One might think that this is little, however, has shown that weight loss of this magnitude can decrease the frequency of diseases like diabetes are type 2 and hypertension in people who do not suffer.

Ultimately, losing weight is essential for reducing the consumption of calories. You do not need to rely on types of diets that are far from our usual eating pattern. Small changes sustained over time are the best choice for anyone looking to lose weight.

A California company (USA), called Sensa, has launched a new product that will help ensure the weight loss of a new and revolutionary, is an odorless, tasteless powder that can be sprayed throughout the food and causing a great impact on the appetite control center, managing to reach that feeling of satisfaction and fullness eating less.

The creator of this product is Dr. Alan Hirsh and after years of studies managed to get this product, which achieved very significant results. In a period of six months a total of 1,436 women and men used the dust which they called “Tastant” in all the food they consumed and had a loss of approximately 15kg, about 15% of total body mass.

Importantly, participants did not have to make any kind of diet or exercise regimen.

The best part is that this product to be odorless, tasteless and not directly alter the digestive system does not cause any unpleasant side effects. As the creators of this product expected to find indifference and suspicion at the time of its release, they decided to do it for free, giving the opportunity for those interested in trying to do so without paying anything and then decide if they liked it or not.

Physiological regulation of weight

The normal individual maintains its body weight in a predetermined level of stability quite remarkable, given how much they vary daily calorie intake and activity level. Given the physiological importance conserve energy reserves is difficult to lose weight and keep it off voluntarily.

Appetite and metabolism are regulated by a complicated network of neural and hormonal factors. Hypothalamic centers for hunger and satiety are essential in these phenomena.

Some neuropeptides such as corticotropin-releasing hormone (corticotropin-releasing hormone, CRH), the melanocyte-stimulating hormone alpha (α-melanocyte stimulating hormone, α-MSH), and the transcript related to cocaine and amphetamines (cocaine and amphetamine-related transcript, CART) cause anorexia by acting on the central nervous system (CNS) in the satiety centers.

Gastrointestinal peptides ghrelin, glucagon, somatostatin and cholecystokinin are those which cause satiety and reduces food intake. Hypoglycemia suppresses the action of insulin, which lowers glucose utilization and inhibits the action of the satiety center.

Weight loss Occurs
when energy intake exceeds the calories available for this purpose. In most individuals, about half of the energy from food is used as basic functions such as keeping the body temperature. In a 70 kg weight, basal metabolism consumes about 1 800 kcal / day.

About 40% of calories consumed in exercise, although athletes can use more than 50% when performed in a marked degree. About 10% of caloric intake is used for dietary thermogenesis, a process in which energy is consumed in the digestion, absorption and metabolism of food.

The mechanisms of weight loss

The lowest food intake, malabsorption, loss of calories and increasing energy needs . The changes in body weight may be due to the changes in tissue mass or fluid volume contained in the body. In general, a shortfall of 3 500 kcal corresponds to a loss of 0.45 kg of body fat, but must also take into account water (1 kg / L) to be won or lost. Weight loss that lasts weeks to months usually means a loss of tissue mass.
