Do weight loss supplements work?

Do weight loss supplements work or are they a waste of time? Find out if your magic pills are worth the money or if they are doing you and your wallet harm.

A new study has shown that no research evidence exists to show that any one weight loss supplement has significant weight-loss results. Some can even affect your health negatively.

The study looked at supplements which fell into four categories: products such as chitosan which block the absorption of fat or carbohydrates, stimulants such as caffeine or ephedra which boost metabolism, products such as conjugated linoleic acid which claim to change the body composition by decreasing fat and appetite suppressants such as soluble fibres.

It found that many of the product manufacturers had never conducted randomised trials, and where data had been collected the resultant weight loss was usually no greater than one or two kilograms.

A few products, such as green tea, wet fibre (such as cooked oatmeal), and low fat dairy supplements can have a small weight-loss benefit, but only when tested as part of a reduced calorie diet, including lots of fruits and vegetables and exercise.

It is not unexpected that most supplements do not work. The problem is in the nature of our modern foods. And I don't mean just fast food although it is more often high fat, sugar and energy and also low in real nutrients. But an insidious change has been imposed on our fresh produce over the last 20 years and through selection, growers have replaced what are now rare sugars in our fruits and vegetables with sucrose or common sugar. Most people think they are eating healthy food if they consume mangoes, melons, grapes, stone fruits, dates, sweet potatoes, sweet corn, peas and sweet tomatoes etc. Unfortunately, there is 3% more sucrose in most mangoes than in the same weight of cola.

So what you ask?

Well the sucrose in combination with a little fat in the diet plays havoc with our blood sugar levels and switches the way we run from burning sugars to storing fat. There's a whole lot of biochemistry involved but this is the executive summary.

So taking most supplements might interfere with a minor part of our metabolism but as long as we continue to eat sucrose and fat together we will over-come the positive (albeit minimal) effects of the supplements.

Only one strategy will work with weight loss. To discover how, have a look at www.weightlosswithsuperfoods.com and learn of the real benefits to your ideal weight from a whole raft of nutrients that have quietly disappeared from our foods as the sucrose has been bred in.

I'll also give you a way out of the sucrose trap.

VicCherikoff,
I have insulin resistance (my BGL is normal but I make far too much insulin). I was gaining weight even though I am not a big eater as such especially in summer. I tend to "go off my food in hot, humid weather. I went to a diectician who put me on the right track - high protein, low carb diet with fruit -some have lower sugar content- and plenty of vegetables. But some of them are higher in carbs. There are good and bad carbs. You can check them in google search --carbohydrates in fruit and vegetables. Carbohydrates convert to sugar. There are a few different forms of sugar too. I was told that the more sweet food you eat the more you want. I have proved this to be true. The site mentioned above is very useful.
