Does Conjugated Linoleic Acid Work?

Filed under: Natural Weight Loss — Dr. Alan @ 11:23 am

Conjugated linoleic acid is a natural substance found in many of our foods that according to many studies can reduce fat and improve muscle mass in the body. Taken as a supplement with no change in eating or exercise habits, it would not make you lose weight but it could help you lose fat. It is often taken by men looking to lose weight and bodybuild at the same time, but it can also be useful for anyone who is overweight and under-exercising, as any increase in muscle will increase the metabolism, burning more calories.

Like many natural weight loss products, conjugated linoleic acid (CLA) combined with a flexible healthy eating plan can lead to gradual long term weight loss and help you get out of the yoyo dieting cycle where you are constantly losing and gaining the same 10, 20 or 50 pounds. Yoyo dieting is very bad for the health. It is better to remain overweight than to keep on losing and gaining, losing and gaining.

Most experts (unless they are trying to sell you something) agree that the diet that works best in the long term is the non-diet, where instead of eating special foods and banning others, you eat slightly smaller quantities of a normal healthy diet. If you are currently living entirely on pizza, fries and chocolate, then okay, some changes may be overdue. But you can still have small portions of all of those foods from time to time. If this is the kind of diet that you want, then CLA can help reinforce your plan by boosting your fat loss. Dr Michael Pariza of University of Wisconsin-Madison, reported to the American Chemical Society that CLA “doesn’t make a big fat cell get little. What it rather does is keep a little fat cell from getting big.”

Many studies have been done on CLA. One study published in the Journal of Nutrition found that people taking CLA lost on average six pounds of body fat more than a group that took a placebo. The researchers discovered that you need around 3.4 grams of CLA per day for it to be effective. CLA is found in food, especially meat and dairy products, but supplementation is necessary for most people to reach that level.

Another study at Purdue University, Indiana, found that CLA improved insulin levels in about two-thirds of diabetics, and slightly decreased their blood glucose level and triglyceride levels, suggesting that it may help to maintain normal insulin levels. But see your doctor before taking any supplements if you have diabetes.

There are no magic pills for weight loss but if you are willing to commit to reducing your body fat permanently, CLA may help you. Keep in mind that its main effect is to convert fat to muscle, which by itself will not weigh any less. But your body will look slimmer and feel healthier if you do this, and combined with a good weight control eating plan conjugated linoleic acid can help you move toward your ideal weight too.

Does Alli Work?

Filed under: Natural Weight Loss — Dr. Alan @ 10:20 am

Does alli work as a weight loss pill? The quick answer seems to be yes, but there is a downside, so read on.

Alli is the over-the-counter name for orlistat which is also available in prescription form as Xenical. If you are going to ask for it you may like to know that it is pronounced like ally, not alley. It is essentially a fat blocker. It works by preventing the body from absorbing the fat from the foods that we eat, and it is the one freely available drug that has FDA backing for its claims to aid weight loss. You might think you could eat all the fatty foods you liked and then take alli to negate the effect but sadly that is not true. It should always be used in conjunction with a low fat diet plan under the supervision of a doctor.

The amount of weight loss achieved with alli is variable. In one study involving one-year clinical trials, between 35.5% and 54.8% of subjects attained a 5% or greater decrease in body mass, although we do not know how much of this mass was fat. Between 16.4% and 24.8% of the subjects achieved a 10% or more decrease in body mass. In combination with a calorie controlled diet, the effects could be expected to be greater. It was also shown to reduce the risk of developing type 2 diabetes. The participants regained an average of one third of the weight that they had lost after stopping alli, but this is typical of most dieters.

The main disadvantage of alli is the side effects which center around digestive and bowel problems. The higher the fat content in the diet, the greater these side effects are likely to be, as the undigested fat is expelled from the body. Flatulence, loose stools and bowel incontinence can result, especially in the early stages before the body is accustomed to the drug. The manufacturer’s website warns, “You may feel an urgent need to go to the bathroom. Until you have a sense of any treatment effects, it’s probably a smart idea to wear dark pants, and bring a change of clothes with you to work.” You really need to want to lose weight to take alli!

However these side effects are reduced if you stick to the recommended low fat diet and as the manufacturers hint, the potentially embarrassing side effects can even be helpful in encouraging you to keep to your diet. Always remember that alli does not claim to work without consistent efforts toward weight loss from you. What they do claim is that it can improve your weight loss by up to 50%. That would mean a person who lost 10 pounds without taking alli would lose 15 pounds taking it. It boosts your weight loss and rewards your efforts with better results than you could get by yourself. Note though that individual results will vary and are not guaranteed.

Sadly there is no magic diet pill that will melt away your excess pounds while you sleep, but alli is a pill that has documented results. If you are determined to lose weight and have been struggling with diets without much effect, it may be a good time to discuss it with your doctor and find out does alli work for you.

Fad Diets: Why Are They Bad?

Filed under: Natural Weight Loss — Dr. Alan @ 9:17 am

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.

Free List Of Negative Calorie Foods

Filed under: calorie consumption — Dr. Alan @ 8:11 am

You will find a free list of negative calorie foods below, but first let’s consider what this means. There is no such thing as a negative calorie - a calorie is a unit of heat and it cannot be negative. So when people talk about negative calorie foods, this just means a food whose calorie level is low enough that it takes more energy to eat and digest it than the food contains.

For example, if you consider water to be a food, then cold water is certainly a negative calorie food. It contains no calories at all and the body has to expend energy to bring it up to blood temperature. So every time we drink a glass of cold water we burn up a couple of calories and lose a little weight. But there are very few foods like this. Most foods that are on the list do not really use more calories than they add, or if they do the effect is negligible … until you remember that at the same time the body expends energy just to keep alive and breathing. Celery for example does not give us enough calories to cover both the energy that it takes to digest it, plus the energy that we expend even when we are doing nothing. So that is why people call it a negative calorie food.

Negative calorie foods are most attractive to anorexics. A negative calorie diet would obviously result in starvation in the long term and nutritional deficiencies can occur surprisingly quickly. The calories burnt usually come from muscle mass, and the result is debility and wasting.

A more healthy way to use a negative calorie diet is as a form of fasting or detox. It is something you can do for one to three days right after the Christmas season or another time when you have been eating a over-rich diet. Provided you are otherwise healthy it can be a great way to clean out the system. However it is still best to take medical advice before attempting this.

If you decide to use a negative calorie detox, keep the following points in mind:

1. It is never a good idea to eat huge quantities of one type of food, especially fruits. A lot of foods contain substances that can be damaging if consumed to excess. For example, the acid in grapefruit and pineapple can damage your stomach lining. Other foods put an excessive burden on the liver or may cause diarrhea. So try to use all the different foods in small quantities.

2. Do not spend all day eating. You will just become bloated and feel sick. If you are only doing this for a couple days, you should not feel too hungry. Plan four or five salad meals each day, and let your digestion rest at other times.

3. You will feel more satisfied if you eat slowly and chew your food thoroughly. You will also use more calories that way. So if the foods can be eaten raw, that will be more effective than cooking them. Foods like carrots and beets will also be more satisfying if you eat them grated.

4. Schedule time when you do not have any important commitments. As with fasting or any kind of detox, you may suffer some uncomfortable symptoms including headaches, tiredness, depression and irritability. If these become severe, stop the diet and see a doctor.

5. When you end the detox, plan a gradual return to normal eating.

If all the above points are checked and passed, let’s move on to the list of foods.

* Apples
* Asparagus
* Beets
* Blueberries
* Broccoli
* Cantaloupes
* Carrot
* Cauliflower
* Celery stalk
* Celery root
* Cranberries
* Cucumbers
* Eggplant
* Endives

Please use this free list of negative calorie foods wisely.

Garcinia Cambogia Extract - A Natural Weight Loss Supplement

Filed under: Natural Weight Loss — Dr. Alan @ 7:09 am

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.
