Rankings of the fad diets

  1. 1. ==== ====For Part 2 of this article, videos and more information on latest diets and weight loss programs,please download a report @,%20weight_loss==== ====THE 200 POINT SYSTEMWith so many different diets available, how are we to knowwhat works and what is safe? The only way to be sure is todiscover the authors background and the research behindthe diets methodology. Every good diet should give abackground about the author and his/her credentials andexperience in the fields of nutrition and biochemistry.However, even a vast resume does not mean a credible andsafe diet. But it does suggest, at least, that the author hassome knowledge of nutrition. Providing research behind thediet proves that the diet is not something the authorinvented, so long as the research is not self-serving andaltered to fit a hypothesis.Some diets may not need a great deal of tests and studiesbehind them, simply because they are based onfundamentals. For example, many womens magazineshave articles on dieting and weight loss, but they arecommon sense suggestions that most people concernedabout weight should know already: "Eat smaller meals", "cutdown on sugar and fat", etc., are typical philosophies. Morestructured diets should give some scientific reasons for itssuggested success, preferably case studies and researchperformed on everyday test subjects, as well as athletes.Since we have established the importance of eating abalanced diet in accordance to selecting healthy foods andobtaining RDA minimums, it is possible now to rate thediets in accordance to those specific criteria. Begin with ascore of 200 and subtract 10 points from the total for eachstatement below in which the diet concedes. An ideal dietshould maintain a score of 200, but a score of 160 orgreater is acceptable.1. The diet does not include the food groups in adequateamounts. Some fad diets eliminate one or more of the foodgroups. Do not deduct 10 points if a food groups nutrients
  2. 2. (e.g., carbs, proteins, fats, fiber, vitamins, and minerals) areadequately substituted with that of another food group.2. The diet does not provide at least 45% of its calories fromcarbohydrate sources. In order to prevent ketosis, at least150g of glucose/day is required. Thats 33-50% of totalcalorie intake on a 1200-calorie diet. Keep in mind that isthe minimum. For highly active individuals, that amountshould increase to 60% at times, i.e., immediately afterexercise.3. The carbohydrate content exceeds 20% concentratedsugars. At least 80% of carbohydrate sources should becomplex, and preferably in the form of vegetables, seeds,and legumes.4. The protein content exceeds 30%. A very high proteinintake is unnecessary, it places additional strain on theurinary system, and it is a poor source of energy. Thirtypercent is more than adequate, even for growing childrenand teenagers. The only group that requires higher proteinintake are those who recently suffered a severe injury (e.g.,leg amputation), infection, or surgery. However, theseindividuals will be under the care of a physician with aspecial high protein diet.5. Protein content accounts for 15% or less of total calories.Although unnecessary in large amounts, protein still hasmany vital functions, including tissue repair and theformation of enzymes.6. Fats exceed 30% of total intake. Besides increasing therisk of cardiovascular disease, high fat diets have not beendemonstrated to decrease weight better than other methodsof proper eating.7. Total fat consumption is less than 15% of total calories.Fat in moderate amounts is essential for a healthy diet, andsuch a diet provides taste to many foods. Fat intake below15% for long periods, for most individuals, is unrealistic.Fat intake that is too low can also be detrimental to childrenand teenagers who require ample kcalories for continuedgrowth.8. Total fat consumption is less than 25% essential fattyacids, and saturated fat is more than 30% of total fatconsumption. Deduct 10 for each.
  3. 3. 9. The diet does not suggest common foods, meaningfoods you should be able to obtain at any grocery store ormarket.10. The foods for the diet are expensive or monotonous.Some diets require the purchase of their foods orexpensive organic foods only obtained through health foodstores. Some foods taste so bad they are difficult totolerate repeatedly (e.g., seaweed). Deduct 10 for each.11. The diet consists of an inflexible meal plan. The dietdoes not allow for substitutions or deviations, requiring aperson to live under house arrest with the same foodselections every day.12. The diet provides less than 1200 kcalories per day.Less than that and the bodys basic functions may not begetting the energy, vitamins and minerals needed to workproperly, and the dieter almost is certain to feel hungry allthe time. Diets below 1200 kcalories should be reserved forthose under the supervision of a dietitian or licensedphysician.13. The diet requires the use of supplements. If the dietprovides adequate energy and it is well balanced,supplements are unnecessary. Fat accelerators, such asephedrine, may increase the rate of weight loss, but the dietshould be able to stand on its own merit. Some diet clinicspromote a vast array of herbal preparations and fataccelerators, and this is where these clinics make theirmoney - not in their knowledge and ability as nutritionists.14. The diet does not recommend a realistic weight goal.Diets should not be promoting the body of a Greek god or asupermodel. They should not be suggesting that a personlose 100 pounds (even if 100 pounds overweight). Norshould diets recommend weight loss below an idealweight.15. The diet recommends or promotes more than 1-2lbs/week weight loss. Do not expect to lose more than 1-2pounds of fat a week - it is physically impossible unlesschronically obese, at which point 3 pounds may bepossible. If more than two pounds is lost per week, thebody change is due to a loss of water and/or muscle tissue.Gimmicks that promise 10 pounds in 2 weeks are eithersimply not true or else something other than fat is beinglost. Also keep in mind that the more fat a person wishes to
  4. 4. lose, and the less a person has, the more difficult andslower it will be to lose additional fat.16. The diet does not include an evaluation of food habits.Dieting should be a slow process by which a personchanges normal eating habits. It should not include lookingfor quick fixes and quick plans promising short cuts andextreme changes - a person would never stay with theseprograms and such diets do not work long-term. Thenumber of kcalories eaten, and the food selections and theiramounts, should be reevaluated on a regular basis...perhaps once every 1-2 months to determine the programseffectiveness.17. Regular exercise is not recommended as part of theplan for proper weight loss. Weight loss occurs twice asfast with exercise, and without exercise there is a greatertendency to lose lean muscle tissue as well as fat. This isnot ideal.OVERVIEW OF VARIOUS DIETSLow Carbohydrate Diets: Ketosis occurs, and this presentsthe same problems as fasting. Once glycogen stores arespent (which happens quickly with athletes and those whoexercise regularly), glucose must be made from proteinsources, and there is greater wear on the kidneys as aresult. Even on a high protein diet, some protein will betaken from body tissues in order to produce enough energyfor the nervous system and regular activity. The onset ofketosis is an indication that this process has begun and it isnot a positive aspect, regardless of what pro-high-fatauthorities indicate.Great weight loss on a low-carb diet is evident because ofthe fact that carbs hold water in the muscles at a ratio of 1:3.As carb intake decreases then so, too, does water retention.Much water flushes as a result of lack of glycogen to holdwater molecules. Moreover, by increasing protein intake,excess nitrogen flushes with even more water since thekidneys use water to dilute the concentration of nitrogen.Once leaving a low-carb diet and the muscles refill withglycogen, fluid concentrations increase and the dieterregains some of the weight.Low calorie diets of 400-600 kcalories that consist primarilyof protein have the same problems as fasting andlow-carbohydrate diets: proteins are used for energy and
  5. 5. weight loss comes largely from water. Low-cal diets mustbe supervised properly by a medical professional and onlyas a last resort for those who cannot seem to lose weight byother methods.
