SUMMARY

A zero-fat diet is unsustainable and detrimental to health, as essential fatty acids are crucial for various bodily functions, including energy storage and cellular structure. Participants in the discussion highlighted that while one may survive temporarily without dietary fat, long-term adherence can lead to severe health issues due to the lack of essential fatty acids like omega-3 and omega-6. The consensus is that fats are vital for brain function and overall health, with some arguing that cutting out fats while maintaining caloric intake may not lead to immediate weight loss but will compromise health significantly.

PREREQUISITES
  • Understanding of essential fatty acids, specifically omega-3 and omega-6.
  • Knowledge of human nutrition and the role of macronutrients.
  • Familiarity with the concept of lipogenesis and energy storage in the body.
  • Awareness of the implications of malnutrition and essential amino acids.
NEXT STEPS
  • Research the role of essential fatty acids in human health.
  • Learn about the consequences of a zero-fat diet on metabolic processes.
  • Explore the relationship between dietary fats and brain health.
  • Investigate the nutritional differences between animal and plant-based proteins.
USEFUL FOR

Nutritionists, health professionals, fitness enthusiasts, and anyone interested in understanding the importance of dietary fats for overall health and well-being.

Remove all of the fat you would normally ingest - would you be able to live for long?

I ate a zero fat diet for almost a month once. Surprisingly enough, I don't remember loosing any weight (fatness) and I remember feeling really tired all the time.

Maybe you felt tired because fats are what the body uses to store energy, so you had no energy storage, and instead your body had to be constantly producing fat from what you did eat. But that's not a professional opinion :)

depends. how fat are you now? you can live on your reserves for a good long time.

and despite lipogenesis, there are still fatty acids that are considered essential, like the omega-3's. women are somewhat better at producing omega-3 than men, but even there, I'm not sure how good they would be at it with zero fat in the diet (don't remember the fatty acid it was made from).

unfortunately, tho, there seems to be more http://en.wikipedia.org/wiki/Rabbit_starvation" on the subject than real data, but i don't think i'd try it for an extended period. seems like a really bad idea.

Some of the omega 3's and 6's cannot be made by the body, and thus are essential fatty acids. Most people get more than enough omega-6's, but not enough of the omega-3's. There is also some research which suggests having too much omega-6 without omega-3 can cause some problems.

"Essential fatty acids play an important role in the life and death of cardiac cells." http://en.wikipedia.org/wiki/Essential_fatty_acids
 
I am not very well versed in this, but I know that there are some "essential" amino acids, id est, amino acids that the human body cannot manufacture. If you stop ingesting these essential amino acids, eventually your body will have a shortage and start experiencing the symptoms of certain rare syndromes. These diseases are generally most common among malnourished populations in the developing world and vegans in the west, as animal protein contains all the essential amino acids.

I am unsure if there are essential lipids, but assuming that there are, one is likely to experience similar symptoms. It would not harm you right away, but eventually you would become ill.
 
I should probably add that, as far as I know, no food contains 0 fat. All cells should have some kind of lipid in them, unless some kind of processing has been used to totally remove it, although statistically speaking, the usable fat content might be 0%.

Yes you're right, the research says that without the essential fatty acids, that happens to you.
 
Why would you want a 0 fat diet when 2/3 of your brain is made from fats?

My doctor said fat is essential and told me I wasn't getting enough.

My doctor told me to eat more nachos. [That's my story and I'm sticking to it, esp if Tsu asks]

Oh Yeah! I've heard nachos are really nutritious. Lots of vitamin C in those jalapenos you know.

You need fat. It is the component of a plasma membrane and all your hormones, and some fatty acids even inhibit cancer. Simply put, without fat you will die. Without derivatives from these fats you will bleed out, go into cardiac arrest, or any number of hundreds of ways to die.

I should start selling t-shirts "Save an Olsen Twin! Give her a burger" with a giant cheeseburger picture with dripping water from the lettuce.. mmmm

I think if you trying to lose weight you should cut back on carbohydrates, but not the fats.

Are you asking to lose weight?

i understood the question to be whether fat is essential in the diet. and it is. however, i suspect you would actually live for a long time if you, as an adult, cut out all fat but kept calories the same. you just wouldn't be very healthy or live nearly as long as a person with fat in their diet.

That would be funny!
