I’m wondering how different types of fat are stored in a human body, and how these fats are lost as part of a weight loss regime.
Let’s say that I am fat, and my fat consists of some mix of SFA, MUFA, and PUFA. I’ve read that it takes years to get rid of excess PUFA. Does that mean that other types of fat are lost first, and that PUFA is lost last?
If so, are the types of fat uniformly stored in a body, or does e.g, PUFA cluster around organs or as stomach fat?
This is a good question. I’m not sure in what order the various types of fats are metabolized, but in general, I’ve read that the body rids itself of PUFA’s regardless of weight loss/ fasting so long as you’re not still consuming them. (In other words, PUFAs will be metabolized even if you’re weight-stable.) I imagine weight loss or fasting speeds this process up, though.
Not sure if this is relavant to your question or if I am totally correct but my understand was that SFA MUFA and PUFA doesn’t really apply to our fat storage and loss. We obviously consist of these types of fat but in what ratio generally depends on our genetics and much less on our diet or how we lose weight.
What is relevant to fasting is subcutaneous versus visceral fat. Subcutaneous fat is caused by insulin levels and while too much makes us larger and can have negative health effects, the negative health effects are far less severe than those affected by visceral fat which is the fat pumped out by the liver and stored under the abdominal muscle/wall around your internal organs which is what you think is PUFA?
My understanding is that fasting really helps in getting rid of visceral fat first although it depends greatly on what you eat. table sugar and anything very high in fructose, alcohol or even some artificial sweeteners such as sorbitol will bypass the insulin system and cause the liver to pump out visceral fat.
Obviously time spent not eating is good for this and thus the health benefits are seen. I also find I don’t have as much room for crappy foods with those ingredients. If this is all there is to it, I don’t know.
