View Full Version : question about these low-carb theories

Nov 12th, 2006, 09:51 AM
Hi, I just read an article in a german magazine about nutrition. http://www.zeit.de/2006/46/Ernaehrung

The article states that the latest trend in the US is a so-called low-carb nutrition which for some people even turned into a carbohydrates phobia.

Some time ago it used to be the fats that were demonised but now after some scientists brought up these low-carb theories so many people suddenly follow the low-carb craze. It's like the good and the bad switched their roles.

Now I wonder how people can actually believe any advise about what type of nutrition is good and bad when there are countless different and contradictious theories coming from everywhere.

What are your thoughts?

Hmm.. my $0.02. You need a balanced diet. Carbohydrates are not bad, fats are not bad. You need both. But there are good carbs and good fats and bad carbs and bad fats.

Quite simply, you want the complex(?) carbohydrates that are found in some cereals and vegetables. You also want essential fats like those found in fish.

What you don't want are simple(?) carbohydrates found in sugars and confectionary. You also don't want saturated fats found in fast foods.

That's the very simple way of looking at things from top of my head. So in other words, DON'T ever cut out food groups. There are good foods in every group. Eat a balanced diet and EXERCISE.

Carbohydrates and fats are both fuel sources. When the body burns fuel it uses up all the carbs first and then starts on the fat. The problem is that most people overeat on carbs, and therefore rarely burn much fat. Eating lots of carbs is part of most cultures' lifestyles, almost like a craving, which it is very hard to break out of. The proposed solution is to switch to a low- or no-carb diet, thus obtaining most of your body's required daily calories from fat (this is not as unhealthy as it sounds). This way you are less likely to overeat and will have a good chance of some weight loss and fat loss. The downsides of such a diet can include bowel problems due to not enough fibre, kidney problems, and heart disease from eating the wrong fats. In theory, a well-maintained low-carb diet is supposed to be healthier for humans, who have never really evolved to digest carbs well. However, if you try it, ou are advised to stick with it as a permanent lifestyle choice if you want to keep the health benefits (i.e. if you try it for 2 months and then switch back, you will regain any lost weight).
