Carbs, Fat and Body Fat


Quote  |  Reply

I found this interesting.

The body treats carbohydrates differently than fat calories. The difference comes from how the body stores the energy of different food types. It is very inefficient for the body to store the energy of carbohydrates as body fat. When your body tries to turn carbohydrate into fat, it wastes 23 percent of the calories of the carbohydrate. But fat is easily converted into body fat. Only 3 percent of the calories in fat are burned in the process of conversion and storage. It is the type of food that affects body fat the most.

wait, so fat is worse than carbs or the other way around.  i prefer eating fat over carbs.  its the only way i lose weight.

this is saying fat that is found in food is easier for the body to store as body fat and that it's not as easy to store the energy from carbs as body fat.

obviously you still need fat. good fats are found is plants and are usually best to consume as whole foods (avocado, olive, nuts, seeds) and not just vegetable oils.

i dont know...fats may be stored easier, but i sure crave and eat carbs a lot easier.  i dont know.  i like eating less carbs and more fat and protein.  ever since i stopped counting grams of fat and started counting carbs i have been steadily losing weight.  low fat never helped me.  but then again everyone is different.

it's not talking about weight. it's talking about body fat. fat weighs less than the same volume of muscle.

weight isn't the number one indication of health. i mean if you have trouble with consuming way too many carbs then you should count them but eating low carb and not paying any attention to your fat intake isn't going to help. you might lose weight but you may be increasing you body fat (percentage).

you can be 115 pounds and still obese in terms of body fat. any weight you are you will look visibly smaller if you're in the healthy range for body fat then if you are the same weight and have a higher percentage of body fat.

not trying to be a downer. i just thought it was interesting because so many people have this carb phobia.

im sorry but i dont agree.  i dont believe you can be 115lbs and obese.  eating and being fat arent directly proportional.  the fat you eat and the fat you store are different.  i also dont think it is a carb phobia.  i am insulin resistant which means that the excess insulin in my body converts any sugar (including both simple and complex carbs) into body fat more efficiently.  for me eating dietary fat actually reduces my body fat.  whereas eating low fat and higher carb actually makes me store more body fat

I don't buy it either. A calorie is a calorie, unless like jessicabc you're insulin resistant and then carbs are more likely to be stored as fat. Obviously you don't want to be drenching everything in butter but I really don't see how eating fat makes you get fat. That's more what sounds like a myth to me. Like, I don't do well on low carb diets, but Ive seen results of people who have and have dropped tons of body fat. Have you ever heard of the guy who writes a low carb health blog, Mark Sisson? The guy has like 5 percent body fat and he routinely eats butter, coconut oil, and more fatty cuts of meat. He's not just saying that either, he's got pictures of himself on his blog and you can see every muscle in his abs.

I would like to see the actual research to back this up, not just someone's opinion on a website.

Yes it is true that the fat you eat is more readily stored than carbohydrates however carbohydrates (esspecially simple carbs) spike blood sugar stimulate production of insulin and can cause you're body to store more fat, If you're overeating. That being said, one should not avoid one or the other. A calorie is a calorie and as long as you don't eat more than you burn you wont gain weight. An optimal diet should be balanced with calories being 15-20% protein 20-25% fat and 50-60% carbs.

FYI I'm not a dietician or anything but I just took a nutrition class so its all fresh in my brain Laughing

i don't have research but that website was created with research done by a committee of physicians.

i thought it made perfect sense.

where as eating a diet high in saturated fats and low in grains is horrible for you. i have no idea who mark sisson is or if any of that is true but eating like that (even if you eat when your caloric range) is not healthy. any doctor or dietitian can tell you that.

Interesting article but there were no scientific studies to back up the claims which do by the way contradict what is commonly held to be true.   Therefore I was disappointed because I thought you might have found a source for some new science that would change the way we have to think about our food.  Unfortunately, all I found were unsubstantiated claims that were pushing an agenda.  So based on that I don't buy it.

not 115 and obese by weight standards but in the obese category for body fat.

anyway if it is true that you lose weight by eating tons of fat and not eating very many carbs i don't think that will be something you can keep up to maintain health.

There was a study done where a group of people ate a really high fat diet (like 70% of calories came from fat) and low carb and lost more fat and saw improvements in their cholesterol and other risk factors for heart problems than the group that ate low fat and high carb (I think the high carb group actually had an increase in some heart disease risk factors).

Did they say what kind of fats, though?  I suspect a diet like that must have been fairly nut-heavy just because there aren't that many edible foods with that high of a fat content.  (Unless you consider a stick of butter with nothing else to be edible; which I don't.  Smile)

 No offense, but you dont know what i can and cant do and what is or isnt healhty.  there is sooooo much research beyond this one article that you found that talks about the dangers of eating too many carbs and the benefits of having your fat intake be more than your carb intake--including saturated fat.  When I do low carb I LOSE WEIGHT.  When i eat carbs I GAIN WEIGHT.  Beyond the actual weight issue, when i was eating high carb, low fat i had a receding hairline (im a 20 year old girl), i wasnt getting my period (symptom of insulin resistance), my skin was dry, i was having brain fog and headeaches, and i had to take a nap everday.  After just 5 or 6 weeks of doing low carb and higher fat, my hair is growing back in, my period has come back, my skin is clearer and softer, i dont have brain fog, my headaches have gone away completely, and i havent taken a single nap.

Can you really tell me that im not better off doing low carb?  Im sorry, but you are very misguided. 

 

EDIT:  Also, unless you are very very short, you cant weigh 115lbs and still have obese amounts of body fat.  Once you factor in the weight of your skeleton, organs, and muscles,  there isnt a lot of the 115lbs left to be body fat.  Seriously, have you ever heard of an obese 115 lb person? Where is the evidence of that?

i wasn't trying to tell people to eat low fat. we need fat (most of us are probably consuming too much already though and the wrong type) as i said before. i was just trying to get people to rethink the low carb issue. carbs are important fuel as is fat.

and i'm not trying to tell you what you can or cannot do. i'm just saying that a diet high in saturated fats isn't going to contain very much if you are trying to stick to a caloric range that is going to cause you to lose weight since fat after all had 9kc/gram where as carbs have 4kc/gram so you can eat more of it and actually consume less calories. and that decreasing something to an unhealthy level in your diet (unless suggested by a dietician for medical reasons), be it fat or carbs, is not a permanant weight loss solution.


yes you can be skinny fat (meaning low body weight and high body fat percentage. read)

Are you saying that the pcrm is pushing a low fat agenda on people in order to...make money for companies offering low fat or non fat products?

i'm not quite sure what you meant by this.

anyway here is a few more sources i found.
source #1

"if the body doesn't receive sufficient carbohydrate, it breaks down muscle and other tissue to produce glucose. This causes a build-up of waste products called 'ketones'. This state, known as 'ketosis', is commonly seen in people who are starving, suffering from anorexia nervosa or with untreated insulin-dependent diabetes. Ketones make the blood acidic. Ketosis can be fatal in severe conditions, particularly for pregnant women, their unborn babies, and for people with diabetes. There is also evidence that the heart may not be able to function to its full ability when ketone bodies are its main source of fuel."
source #2

source #3

i think your confusing ketosis with ketoacidosis.  ketoacidosis is what the diabetics get from having HIGH blood sugar--you get sugars from carbs, by the way.

also, your sources are not very convincing. its all second hand information with very little scientific proof.  any fitness website  or vegan website can post about how bad saturated fats (usually from animals) are and stuff but where is the data?  read the book "good calories bad calories" by gary taubes.   do yourself a favor and go on google and research the GOOD things about low carb and high fat, just to get a counterperspective.  you'll be amazed how much info is out there that completely contradicts the idea of low fat high carb being good.

Unlike Jessica, in the your-mileage-may-vary weightloss strategies, I find it so much easier to lose weight counting grams of fat than trying to cut the carbs. If the quoted information in the OP is correct, perhaps that is why it works for me.

Again with the YMMV though, I also find it challenging to meet a mere 1200 calories while counting fat, and I've had to push myself up to 1400-1500 calories with my activity level.

If I ate as much fat as I wanted and cut back on the carbs, I know that would shift drastically.

In the end, there is no one size fits all, no matter how vociferously we may love our particular methods.

i'm not confusing anything. those aren't my words. that whole paragraph is a direct quote from source #2.

"Ketosis should not be confused with ketoacidosis (diabetic ketoacidosis or the less common alcoholic ketoacidosis), which is severe ketosis causing the pH of the blood to drop below 7.2. Ketoacidosis is a medical condition usually caused by diabetes and accompanied by dehydration, hyperglycemia, ketonuria and increased levels of glucagon. The high glucagon, low insulin serum levels signals the body to produce more glucose via gluconeogenesis and glycogenolysis, and ketone bodies via ketogenesis. High levels of glucose causes the failure of tubular reabsorption in the kidneys, causing water to leak into the tubules in a process called osmotic diuresis, causing dehydration and further exacerbating the acidosis."

here

by the way all my sources aren't fitness sites and none of my sources are vegetarian or vegan site.

#1- government consumer health site accreditation

#2 is admittedly a fitness site

#3 is a non-profit consumer, nutrition and public health organization partnered with the american council on science and health and a lot of other respectable organizations read

though i do agree with dreadfulpenny that one size does not fit all there are basic ideas about health that benefit everyone. i feel that this idea (balance and moderation) is one of them. and that it will really benefit people in the long run.

oh, and i wanted to mention again that i am not all about low fat diets. i'm about diets that as stated above have balance and practice moderation. i'm not a low fat diet follower. i am about good fats in good amounts. but for people that are trying to lose weight and reduce their body fat percentage i thought the information might be useful.

i agree that moderation of everything is best and one size definately doesnt fit all, but the size that fits me is low carb higher fat.  if you are doing good and feeling healthy then you should do what makes you feel good.
