And don't eat according to "the food pyramid" which is woefully unballanced and will cause you to ingest far more carbohydrates (and especially sugars and starch) than you need.
That thing is the cause of most of the "obesity epidemic" and the main reason why most of those who are overweight can't loose weight (at least not permanently).
"Low fat" does nothing if you replace it with high starch and/or sugars. We're told to eat loads of bread, fruit, and potatoes, and vegetables rich in starch and sugar, all of which ends up as sugar in our bloodstream, eventually triggering diabetes (or if you're lucky to catch it early, the precursor symptoms of hyperinsulinism and thyroid malfunction).

Sadly, the "diet gurus" who call themselves dieticians, diet experts, and sit on government panels, all telling you what to eat, are so set in their ways by decades of misinformation here (which started by the crash programs to increase wheat production during and post-WW2 when it was agreed to "never again" let countries experience famine and free a larger portion of the population for military duty by mechanisation of farms, which is easy with wheat farming) that they'll villify anyone who dares promote science and has a different perspective, one that advocates a more ballanced diet rich in protein instead of carbohydrates.
We're told to drink lots of milk and eat lots of dairy products for much the same reasons, yet all of those are rich in sugars as well (though not as rich as a similar volume or weight of fruits or starchy vegetables).

Things like South Beach, Atkins, et. al. are based on that premise, ballance in diet and taking control over your kitchen by using fresh ingredients rather than prepackaged stuff (all of which is exceedingly rich in starch, sugars, and other cheap filler material, the processed food industry has a definite reason to dislike people eating a diet low in carbohydrates).
When people talk about these diets however, they usually only mention the first stages which are indeed almost devoid of carbohydrates. They never mention that those stages last only 2-3 weeks for most patients/users, and after that carbohydrate intake goes up (though never to the levels the industry and government food gurus would want).
