Dieters say that the steps for the week long cut down is a bit hard to follow but the results are incredibly pleasing to their eyes and the weighing scale.Diets for people who enjoy their food.A special diet is prescribed for each individual depending on his (or her) age and medical condition like obesity or sensitivity to certain foods.
First, you need to understand that your body needs a balanced nutritional diet with adequate daily amount of: vitamins, proteins, minerals and carbohydrates. Get into the habit of eating exactly 3 meals a day. 1. Eat breakfast within one hour of lifting. Breakfast provides at least 30 percent of the total energy and nutrition needed to sustain the human body throughout the day. Therefore, it is very important to have a good breakfast and not to jump. 2. Have a healthy low-fat lunch snack. Have a healthy snack in your lunch hour, low-fat yogurt, for example, the energy to sustain its operation. 3. Have your dinner three hours before bedtime. Have a good dinner three hours before bedtime, never go to bed on a full stomach. Drink at least 2 liters of water a day. 2 liters of water a day help your body burn calories more efficiently and to get rid of toxins. Exercise is a key. By exercising, your body receives a physiological advantage of many benefits, such as: - Weight Control for elevating your metabolism so you burn more calories per day. - The boost in your energy level - Strengthen your heart and lungs - Improve your self-image and confidence. Therefore, do not forget to exercise at least 10 minutes a day. Try to avoid using fats. Try to keep the level of fat in your cooking as low as possible. Calcium to your friend. Include as much calcium in your daily diet can eat: - Oranges - Broccoli - Soybean - Tofu - Sunflower Seeds - Papayas And other sources of calcium. Calcium is a crucial element for bone metabolism. Calcium deficiency is very common. The "average" American diet does not even come close to meeting the normal calcium requirements: 425 mg. a day for men 450 mg. a day for Women So, to summarize: 1. Have exactly 3 meals a day 2. Drink at least 2 liters of water a day 3. Exercise at least 10 minutes a day 4. Avoid fats 5. Make calcium your friend By following these 5 simple rules, the loss of weight in a short time.

Carbohydrates and weight loss

Carbohydrates are the most important source of energy. Carbohydrates are not bad for you, all you need to do is make sure you are eating the RIGHT carbohydrates and you will feel better, reduce the risk of disease and lose weight.
In simple terms, carbohydrates are broken down by enzymes into simple sugars different from glucose which can then be absorbed into the blood. Digestive enzymes are like scissors biological - that cut the long starch molecules into simpler.

According to experts, if we can not burn all the fat we consume, the rest is stored as fat tissue. This ability to burn fat is determined by the amount of insulin in the blood. [Note: an important factor in the release of insulin is the glycemic index (GI) value-carbohydrate food or foods consumed.] When insulin levels are low, mainly in fat burning. When you are high, primarily burning carbohydrate. But a problem arises when insulin levels remain consistently high, as in the case of people who suffer from insulin insensitivity. In such cases, the constant need to burn carbohydrates reduces our ability to burn fat. The result? More fat is stored as fat (adipose) tissue.

In general, the speed of digestion is determined by the chemical nature of carbohydrates in it, and therefore as "resistant" is the activity of enzymes. A simple sugar tends to be much less resilient than a starch, and is digested much faster or metabilized. Things that slow down digestion include the presence of acid (gastric juice or the food itself), and the presence of soluble fiber.

High insulin levels may increase the risk of obesity

This is why the linkage of the high insulin levels, along with a reduced ability to burn fat with obesity. And as you can see, high insulin levels are typically determined by the type of carbohydrates we eat. Foods with high GI foods or trigger higher levels of insulin intermediate or low GI foods. For this reason, the glycemic index is seen as important in the assessment of dietary carbohydrate.

As we have seen, the human body thrives on glucose. Therefore, all food must be converted into glucose before they can be used as fuel. Carbohydrates are easily converted into glucose that the protein or fat and is considered the body's "preferred" source of energy and brain of the essential source of energy.

Simple carbohydrates (with the exception of fruit sugar) are more easily converted into glucose because their molecular structure breaks down faster in the stomach and small intestine. Therefore, these carbohydrates increase glucose levels in the blood fairly quickly (less than 30 minutes). This explains why diabetics who sometimes suffer from an excess of low blood glucose, can quickly restore their balance by eating simple carbohydrates, foods such as sweets.

L-Tyrosine

What is it? Tyrosine is an amino acid which is an essential precursor or "building block" to the neurotransmitters responsible for maintaining metabolic rate. L-Tyrosine is the direct precursor to stimulatory neurotransmitters such as epinephrine and noropenephrine (i.e. adrenaline) as well as certain thyroid hormones and dopamine.
In other words, L-Tyrosine is a precursor to important stimulants to the metabolism. It is also considered a non carbohydrate ATP substrate.
Tyrosine is a precursor to CCK (see section on glycomacropeptide for a discussion on the effects of CCK). High amounts of tyrosine are found in foods high in protein. The body can make tyrosine from the amino acid phenylalanine.
What is it supposed to do?
As the above would imply, tyrosine is an important amino acid for maintaining a higher metabolic rate. As people reduce their calories during a diet, less tyrosine is available to make the natural stimulants to metabolism. Therefore, the metabolism slows down making it harder to lose weight.
Less building blocks for stimulants means a slower metabolism. This is an overly simple explanation, but you get the idea.
This may be one more way the body has built its own safely net to respond to less calories being eaten. By taking L •tyrosine as a supplement you supply the building blocks to these important neurotransmitters responsible for maintaining metabolic rate. This may allow the dieter to bypass some of the metabolic down regulation from a reduced calories diet, thus maintaining a higher metabolic rate making weight loss easier and avoiding plateaus.
Tyrosine may also act as an anorectic (appetite suppressing) supplement via its effects on CCK and other mechanisms. Tyrosine is also sold as a mild stimulant and some feel it may be useful for depression. Under stressful conditions, food sources and phenylalanine to tyrosine conversion may be inadequate to maintain the essential neurotransmitters needed for optimal performance.
What does the research have to say?
The research with tyrosine as a weight loss agent is limited. However, there are studies showing tyrosine can potentiate the anorectic effects of other weight loss compounds, such as phenylpropanolamine and ephedrine making their effects more prolonged and effective. Several animals studies demonstrated that tyrosine is a powerful potentiator of the appetite suppressing qualities of the ephedrine based supplements.
Although human studies using tyrosine mixed with ephedrine are limited, one would expect similar results as found in animals. Because of the extreme complexity of human metabolism and appetite control, effects in people may not be as dramatic as those seen with animals
Tyrosine does not appear to increase the thermogenic effects of the ephedrine caffeine products, but work at the level of the brain to reduce food intake and maintain the availability of stimulatory neurotransmitters. There is research suggesting that the positive effects of ephedrine and other compounds are actually limited by the availability of L-tyrosine.
One area tyrosine shines in the research relates to its effects on mental acuity and stress. The military has been particularly interested in tyrosine for use with troops. Tyrosine may also have direct applications to athletes in rigorous training susceptible to Over Training Syndrome (OTS).
