Thread: Fat people, possibly more efficent digestion?

People tend to say that fat people have slow digestion and thin people fast digestion. The focus seem to always be on the speed of it.

Considering person A is fat and eat the same amount of food as person B which is thin over a period of 10 years.

Couldnt it be that fat peoples bodies are simply more effective? That their bodies are better at absorbing the nutritients?

Interesting idea. My immediate response, though, is that the issue is based much much more on how the absorbed nutrients ultimately get used by the and converted into other forms (like motion and thought, etc), and much less about how many or how efficiently those nutrients get absorbed.

If the issue was one of nutrient absorption, then the thinner person would likely be sickly and weak, whereas we know that (as a general rule) it is the thinner person who tends to be MORE healthy.

Also, instead of digestion, the word "metabolism" may be a better fit for your thought. Cheers.

Nice theme
But fat is essential in human life
And I find that dealt with must be concentrated in periods of work
And not in the rest periods
Because the fat you need to work hard to get rid of them

True. But isnt most of the health problems when it comes to obesity the mass itself? So if a fat person worked out and started jogging like crazy he would have alot faster progress when it came to muscle gains and energy than the thin one?

I dont really have any additional ideas neither am i educated in biology in any way, the thought merely came to me that "Hey, maybe the food going slower through means more effective uptake and is a positive trait not a negative one"

We are all pretty efficient at digesting nutrients in our food. There might be some variations in individuals, but it won't make much difference because we are considering (probably) a small percentage of a small percentage.

Nutrients that aren’t absorbed in the stomach move further down the intestine where in some cases (for example, certain fibers), they are digested by special bacteria and re-enter the bloodstream as short-chain fatty acids. This is discussed in Fiber – It’s Nature’s Broom.
Nutrients that pass that stage eventually come out the other end in your poo and we needn’t talk about that much more. I’ll only note in this regards that digestive efficiency in humans is generally very high. Fats are absorbed with about 97% efficiency (e.g. if you eat 100 grams fat, you’ll absorb 97 grams of them), animal source proteins are about 90-95%, vegetable source proteins can be in the 80% range and carbohydrates vary drastically depending on their form, fiber content, etc. But for the most part, with the exception of high-fiber foods, you’re not losing a lot of calories in your poop.

The basic reason some people get fat: they eat too much food.

Well, the most efficient digestive/metabolic people we know are pregnant and brestfeeding mothers of 3rd world countries. Somehow these skinny women grow babies without significant increase in already meager diet, that remains far short of recommended amounts.

As far as nutrients is concerned, for the most part we all absorb vitamins and nutrients the same way. As far as differences in metabolism, while I do metabolism can vary, I think a person weight has more to do with their activity. If two people eat the same amount of food for ten years but one is active and one is less active, the active one will weigh less than the less active one. Depending on how much they eat and how active the one is, that person could still be overweight. Just not as overweight as the person who is less active. Differences in metabolism have little effect I believe over time. The difference is minimal to have any effect on one's weight.

Hey i don't think so.Digesting system depend on how you take your meal and what time period you give between your first and other meal.Yeah it's quite possible that fat people have little bit problem og digesting but it can be happen to thin people also.

It might be so, but it sounds like much of a conjectured excuse. If my digestion would be such that I was two times easier to gain somatical fat then I am right now, I'd just eat less. What I mean to say is that being easier to get fat doesn't mean you have to be fat. I mean, if I were an albino it wouldn't have to mean I'd be covered in sunburns 90% of the time.
