Does fat matter?
If I'm on a 1,700 calorie diet, for the purpose of losing weight, does the
composition of those calories matter? If I burn 2000 calories a day, why does it matter if my calorie intake is derived from fatty foods or non fatty foods, won't I still lose weight because I'm burning my calories than I'm taking in? |

It is simply a matter of calories out versus calories in..........aside from temporary water retention/loss . Some people find it easier to eat fewer calories on a low fat diet or a low carb diet. Its different for everyone, experiment. It is definately easier to eat less if you take your calories through highly nutrtious food. -- Steve http://www.geocities.com/beforewisdom/ "The great American thought trap: It is not real unless it can be seen on television or bought in a shopping mall" |

It is simply a matter of calories out versus calories in..........aside from temporary water retention/loss . Is it? It seems every time I turn around there's some report that indicates that maybe it's not that simple. For instance, wasn't there some buzz recently about how a diet rich in dairy products had people losing faster than one with the same calories but without the dairy? Years ago all the diet experts pretty much ignored the impact of fiber and assumed that 30 grams of fat-free wheat bran flakes had the same calories as 30 grams of fat-free corn flakes regardless of the different amount of fiber. So maybe the problem is that we don't know yet how many calories there *really* are in the things we eat (like those dairy products -- is it possible that lactose isn't metabolized by the body the same way as other sugars?). Weren't there some studies a while back that indicated that a fiber-rich food actually reduced the number of calories eaten in foods without fiber if eaten at the same time? I seem to remember a theory that the fiber-rich foods "pushed" other foods through the intestines faster, reducing the amount of time available for calories in them to be absorbed by the body and therefore reducing the number of calories actually absorbed. Maybe this one has been disporven -- I haven't heard much about it lately. I've also heard that if you are used to a low-fat diet, eating a meal high in fat doesn't affect you the same way as it does for someone who eats a lot of high-fat foods. The theory as I recall it was that your body isn't used to handling all that fat and it goes through your system faster and therefore you don't absorb as many calories. This may be wishful thinking on someone's part, but I have noticed that if I keep to a low fat diet for some time and then have something really fatty it gives me a mild case of diarrhea. I guess I'm just saying that I don't think it's as simple as calories in/calories out for weight control. That's not to say that a diet with a lot of fat is as healthy as one that is low in fat. AFAIK the jury is still out on that. Some people find it easier to eat fewer calories on a low fat diet or a low carb diet. Its different for everyone, experiment. It is definately easier to eat less if you take your calories through highly nutrtious food. Absolutely true! Anny |

If I burn 2000 calories a day, why does it matter if my calorie intake is derived from fatty foods or non fatty foods Because a calorie is NOT a calorie. won't I still lose weight because I'm burning my calories than I'm taking in? Problem #1) Each type of major nutrient has an effect on basal metabolism when burned. If you eat insufficient protein/fat/carb the body will go into starvation mode so each one has a specific minimum you should not go under. For each type it is highly individual as to how much is too little. Normal guidelines for protein run in the 0.5-1.0 gram per pound of current weight range. Normal guidelines for fat run something like 60 grams for women and 80 grams for men (T-Factor Diet). Normal guidelines for carbs are subject for debate but they tend to run in the 50-100 gram range per low carbers. Trick #1) If you go low-but-not-too-low in either carbs or fat, the body gets inefficient. This is why folks don't need to count calories on reasonable low-carb or low-fat plans, they just need to avoid over eating. Recent studies say low-carb beats low-fat by 4%. That's a 4% difference in BMR for the same calories. Problem #2) Each type of major nutrient has an effect on how hungry it makes you. Most folks aren't hungry on low-carb. Some folks aren't hungry on low-fat. Whether you are hungry on low-calorie depends on how low. Trick #2) Eating enough of some carbs makes many people more hungry than before they started. That's why low carb is popular. By eating low glycemic load carbs most of this effect is handled. |

It doesn't matter if you don't care about nutrition. If you want to get
scurvy, beriberi, pellagra, rickets, osteoporosis, a heart attack or stroke etc. then eat whatever you want. |

escribió: If I'm on a 1,700 calorie diet, for the purpose of losing weight, does the composition of those calories matter? No, but very few people ever are on a diet "for the purpose of losing weight." Rather, most people are actually on diets to lose weight and keep it off. In that case, what the calories are does matter. -- bicker® Watch Good Morning America on June 2 to meet members of the National Weight Control Registry, who share their experiences losing weight and keeping weight off for life. |

No, but very few people ever are on a diet "for the purpose of losing weight." Rather, most people are actually on diets to lose weight and keep it off. The high drop-out rate on every plan suggests that most do in fact diet to lose weight and that they don't consider what it will take to keep it off. In that case, what the calories are does matter. Because some foods make you less hungry after you eat them and other foods make you more hungry after you eat them. (Cracker Jacks once advertized that once you eat it it makes you want to eat more). Unfortunately there is no map of what foods do which because everyone is different. |

Gregg,
For weight loss it may not matter much. Eating high fiber foods, tho, has been proven to reduce your appetite. Eating "good" fats can improve your blood chemistry (lipid profile). The best advice is to follow a healthy diet and exercise more - and the best site for this is Harvard's http://www.hsph.harvard.edu/nutritio.../pyramids.html "Gregg Davis " wrote in message ...
