Default 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?

Not as far as losing weight goes. 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.

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!

It sure does.

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.

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.

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
