High fat diet is GOOD for you.

[Trajan]

I was under the impression that the body stores fat as a preference, when one is in a caloric surplus. So isn't the real issue eating too much? The old cals in versus cals out.

Does it really matter where your macros come from, as long as you meet them?

Calories are an extremely poor way to think of nutrition when it comes to metabolism. In reality, there is WAAAAAYYY more going on than calories.

Food satiety is whole different ballgame. Protein and fat both make you feel satisfied long before carbohydrates do, for example. In fact, high carbohydrates may actually turn off the "I'm full" hormone signal (leptin), encouraging overeating.

The other problem with calories in/calories out is that it assumes that calories can only be burned or stored. The body is also entirely capable of just passing them through as waste, or using a molecule of fat or protein to rebuild a cellular wall (again, neither burning nor storing).

True, but calories do matter. There's no getting around that. If I give you 500cal per day, regardless of the nutrient/macro composition, as a healthy active person, your metabolism will tank, and you will lose LBM, etc, etc. Here's my take on cals vs macros debate that if interested:

The Unified Theory Of Nutrition

Food satiety is whole different ballgame. Protein and fat both make you feel satisfied long before carbohydrates do, for example. In fact, high carbohydrates may actually turn off the "I'm full" hormone signal (leptin), encouraging overeating.

It's not quite that simple. Leptin sensitive to total energy and other variables. There's also many other hormones involved in the cascade. It is 100% correct that protein is the most satiating.

The other problem with calories in/calories out is that it assumes that calories can only be burned or stored.

It does not. Correct caloric estimation of RMR/BMR* has to account for all metabolic processes. It can be calculated with very good precision when measured directly, and crudely using formulas.

The body is also entirely capable of just passing them through as waste, or using a molecule of fat or protein to rebuild a cellular wall (again, neither burning nor storing).

See above. I can assure you the scientific community is well aware of the fates of various foods.

Some points are true (but made to sound far more dramatic and "cutting edge" than they really are) and much of it is highly debatable. Cals are just another term for energy really. Energy matters, unless he's found a way to bypass the laws of thermodynamics. I assure you, he has not. I agree totally that the old "cal is a cal and only total cals matter" model is out dated and incorrect, but, that's not news either. The guy does an astounding amount of writing to say essentially nothing in that article. Also reads like some Paleo, or vegetarian (or other dogmatic WOE) doc but I didn't take time to look around. Take with a grain of salt....

* = There's small differences between RMR and BMR, but not important in this discussion

This is a good book on this topic.

it is believed the leading cause of strokes may actually be attributed to sugar vice the "fat" in food that everyone likes to blame.

I have been eating low carb for 5 months and have almost lost 50 lbs. I did a lot of research before really diving into this. There is a lot of science to it. The idea really has more to do with insulin then anything else. Eating carbs/sugars creates an insulin response and that does a whole lot of other things. It is a metabolism...insulin thing. I cannot put it all into words, but I have done a lot of research and understand it.

Either way, it seems to be working well for me, and I feel better.

I went of the diet over the holidays and ate a lot of carbs and they really did make me feel like crap a lot of times.

A good resource for info is DR. Meades ( If memory serves me right). He tells a lot of the science of it and less of the eat like a caveman thing.

To each his own.

I generally eat a bowl of cereal in the morning and nothing until dinner.

I work out with free weights and do cardio by way of cycling, somewhat hard core...

When I do eat, I don't concern myself with fats/calories/carbs whatever. I eat what I want and some might consider me a geezer, so something about what I eat is working.

Me weight is within 5 lbs of what I weighed in high school.

Agonizing about food is silly. Just don't eat so much you get lard ass, otherwise eat whatever appeals to you, and get off your ass and exercise at whatever appeals to you too.

A lot of paleo, primal, atkins ect. is about more then weight though, it is about overall health.

nothing until dinner? is this because you are trying to lose weight or just have no interest in food?
