Garcinia cambogia extract is hitting headlines throughout the western world as a natural weight loss supplement. Several studies have shown that it does help people to lose weight and although as always there are other studies that are less conclusive, it can be an effective weight loss supplement for many people.

Garcinia cambogia is the name of a small tropical fruit that grows in India and Africa. It is one of the citrus family like oranges and lemons. It is too sour to eat but the rind is used as a spice in Indian cooking. The correct name for the substance that is extracted from the fruit as a weight loss supplement is hydroxycitric acid.

Hydroxycitric acid is not a stimulant (like caffeine) or an appetite suppressant, both of which work directly on the nerve centers of the brain and can have undesired side effects, including causing food binges any time you stop taking them.  Instead, HCA satisfies the body's need for energy and improves the signaling system that the body uses to tell the brain when it has eaten enough. This response is often delayed in overweight people, causing them to continue to eat more than they need.

Garcinia cambogia extract (HCA) seems to work best in combination with chromium, which helps to regulate the body's blood sugar levels. Chromium is a mineral that is often lacking in our diets as we get older and a chromium deficit can contribute to weight gain and possibly diabetes. However if you have diabetes already, you should see your doctor before taking any products containing chromium.

As with most supplements, it is best to be cautious and do not take HCA if you are pregnant or breast feeding. Consult a doctor before giving it to children. You may also want to avoid HCA if you suffer from migraine or arthritis which can be worsened by citrus fruits.

HCA seems to work best for people who overeat when they are anxious or stressed, as it will give the same calming effect that they get from food. Generally you do not need to eat any special foods when you are taking HCA, and there are no 'forbidden foods'. Choose healthy foods and you should find that you lose weight and fat slowly but steadily without really trying. You can take slightly smaller portions if you wish and choose fruit instead of sugary snacks but you should not need to go hungry. This is a very natural way to lose weight.

Unlike many other weight loss products, HCA has been extensively tested in research laboratories on both human and animal subjects and no side effects have been found. This natural weight loss supplement is available from many sources online and may be labeled either hydroxycitric acid or garcinia cambogia extract.

It is not surprising that many people wonder why fad diets are bad when they seem to get results. You will find many sites on the internet claiming significant weight loss in just a few days. That type of weight loss is always temporary. It is usually 90% water which will be put straight back on as soon as your body rehydrates, which it must do if you are not going to suffer severe health problems or die.

Other fad diets are not so obviously crash diets with outrageous claims but they are over hyped diet plans that tend to be fashionable for a while and usually make a lot of money for the inventor in associated product sales. In the best cases these are good nutrition plans which will help you lose weight, but which you could probably have gotten for free from your doctor. In the worst cases they will prove so difficult to follow that you will give up after a week.

The bad of fad diets

1. Diets that promise quick and easy weight loss are usually based on eating more of one food type and none of another. These do not give the benefits that you would get from a balanced diet. They may suggest you take supplements but many supplements are not absorbed by the body unless they are taken along with the foods that the diet has banned. After a few weeks, if you stick to it that long, you may begin to develop nutritional deficiencies.

2. Fad diets are often boring and over restrictive. After the novelty of the first day or two, you will not enjoy your meals. You will then start to crave food constantly and will break the diet. You may even feel guilty, thinking it is your fault that you did not lose weight.

3. Most fad diets do not follow recommendations of the American Heart Association and similar bodies for fat levels in the diet. Often the diet will recommend high fat foods and low carbs which if taken long term, could result in heart disease. The promoters may tell you that the diet is only intended to be followed for a short time. But you probably will not reach your goal weight in that time, and then what? You either continue with a plan that is not good for your health, or stop and probably gain back what you lost.

4. Many fad diets do not help you to incorporate enough servings of fruits and vegetables in your weight loss program, or give you the variety of foods that your body needs.

5. Quick weight loss diets are just a temporary solution and do not help you to make permanent changes to your eating habits. Permanent changes are the only way to remain at your target weight once you reach it. Fad diets encourage yo-yo diet-binge cycles of fast weight loss and equally fast weight gain. This is worse for your health and your self esteem than if you had stayed overweight all the time.

Whatever the publicity materials may say, these diets will not help you in the long term. The best way to sustain weight loss is to eat a varied and healthy diet, do not overeat, exercise regularly and avoid fad diets.  Lose weight diet

Are low carb diets safe? How safe is Atkins diet? Are low carb and Atkins diets dangerous to your health? These are burning questions for dieters all over the world.

I have personally tried low carb diets and Atkins diet and these diets made me lose weight very quickly. However not only did I lose body fat weight, I also lost muscle weight. I had very obvious muscle and fat loss because I can visually see my reduced muscle mass in the mirror.

This certainly isn’t healthy. Furthermore, the more muscle mass that you lose, the less toned your body shape is. The end result is that you will end up thin and yet looked flabby with lose skin.

The frustrating part will be that after you are off the low carb or Atkins diet, you will very probably gain back all the weight that you have loss and even more. This is because your muscles are active and they continuously burn calories. Since you have less fewer muscle mass now, your body’s metabolism or capacity to burn calories slows down tremendously.

In other words, when you put on weight again, you are putting on body fat instead of muscles if you do not exercise. You will be fatter and less healthy than before you went on the low carb or Atkins diet. To compound matters, because of lesser muscle tissues resulting in lower metabolism and thus lesser calories being burnt, you are going to get fatter.

Since then I have stayed off both low carb and Atkins diet. Both types of diets are almost similar as they require you to cut down drastically on your consumption of carbohydrates. Atkins diet went a step further by advocating almost no carbohydrate consumption for 2 weeks before adding some carbs to your meals gradually thereafter.

Besides losing muscles, how safe are low carb diets? This is what Dr Lyn Steffen and Dr Jennifer Nettleton from the University of Minnesota’s School of Public Health commentated in a Lancet report, “Low carbohydrate diets for weight management are far from healthy, given their association with ketosis, constipation or diarrhea, halitosis, headache and general fatigue to name a few.”

The doctors warned that the diet increases protein load on the kidneys and alters the balance of acid in the body. This also results in loss of minerals from the bone stores and affect bone strength. The doctors went on to say that, “Our most important criterion should be indisputable safety and low carbohydrate diets currently fall short of this benchmark.”

Dr Atkins, the creator of the Atkins diet died in 2003 after he was alleged to have slipped on an icy road and hurt his head fatally. However his medical report stated that he had a history of heart attack, hypertension and congestive heart failure.

Were Dr Atkins medical conditions related to his low carbohydrates diet is anybody’s guess. Do you want to take the risk by going on a low carb diet? I don’t think I will. If I ever want to lose weight again, I will rather go on the proven method of healthy eating and regular exercises instead of jumping on any fad diets.
