low-carbohydrate diets have become increasingly popular. supporters claim they are notably more effective than other diets for weight loss and provide other health benefits such as lower blood pressure and improved cholesterol levels; however, some doctors believe these diets carry potential long-term health risks. a review of the available research literature indicates that low-carbohydrate diets are highly effective for short-term weight loss but that their long-term effectiveness is not significantly greater than other common diets plans. their long-term effects on cholesterol levels and blood pressure are unknown; research literature suggests some potential for negative health outcomes associated with increased consumption of saturated fat. this conclusion points to the importance of following a balanced, moderate diet appropriate for the individual, as well as the need for further research.

While low-carbohydrate diets have become increasingly popular as a potential, more effective method of weigh loss that has, as well, other health benefits, doctors believe, based on the available research literature, that these diets carry potential long-term health risks. The research literature indicates: first, that this type of diet is highly effective for short-term weight loss but the long-term effectiveness is not significantly greater than other diets: that the extra health benefits are unknown so far, and finally, that there is higher potential for negative health outcomes due to an increased consumption of saturated fat. More research is needed, but this three points seem to conclude on the importance of following a balanced, moderate diet appropiate for the individual.

the excerpt from chapter 2 of "animal farm", by george orwell that is an example of foreshadowing is "these three (snowball, napoleon, and squealer) had elaborated old major's teachings into a complete system of thought to which they gave the name of animalism." animal farm is an allegory of how czarist russia developed into communist russia with all its corruption. old major's teachings represent marx's theories turned into communism, animalism, by the three pigs. this foreshadows the oppression and corruption that will follow this revolt.
