Yes, and, about 8 minutes of true HIIT* at least 3 days a week for 6 weeks is proven to adjust your metabolic run level. Graph your weight. After 6 weeks of HIIT, you'll see weight really shed because you're not burning calories during exercise but 24/7, and because of that metabolic shift, the weight will continue to shed for months even if you stop HIIT. * HIIT is High Intensity Interval Training. It's a technical…

The ill feeling is no doubt from not being used to the higher catecholamnine release.

High levels of serotonin will make most people nauseous.

Common symptoms of thyroid disorders include obesity and/or excessive thinness (not anorexia per-se, but it can look like it), along with a cornocopia of other issues. Certain mental disorders (depression and anxiety) also highly correlate with obesity and/or underweight. A common treatment for ADHD (stimulants) often gets folks to a healthy weight that previously struggled on one side or the other. It’s a complex pr…

>All the various plastics we’ve all been exposed to and other various chemicals are also likely doing something too. Is this based on a study or something, or is it more of a reaction to all the news stories about that lately? (news peddles fear without anything to back it up typically)

I don’t follow the news anymore, but there are boatloads of studies over the last several decades showing some plastics (and commonly used plasticizers) are Not Great in various ways, from hormone interference to cancers.

Most of the more obvious offenders got banned or voluntarily phased out awhile ago, but new variants of many plastics come out every year, and large swaths of existing ones are known bad but don’t commonly get used in good contact anymore so we don’t think about it.

One of those ‘we’ll probably figure out which one in the basket is causing what problems in a decade or two’ situations, and how bad a problem it actually is. Hopefully no thalidomide chirality level horrors, but who knows.

There's a really interesting study they did with pigs. They fed pigs four different diets that had the same amount of calories, but varying ratios of n3/n6 fats.

It's a very neat demonstration that "all that matters is calories" is not true; your metabolism, and thus how you use the calories, is influenced by…

Where in this study does it suggest that calorie intake was limited? The only line I saw relating to calorie management was this one:

|All the pigs had ad libitum access to diets and water and consumed the diets for 2 months.

So they could eat as much as they wanted to, it seems.

I feel like anybody, including scientists, that speaks about hunger when it relates to being overweight, has never been overweight, or is lying to themselves. We don’t eat because we’re hungry, we eat because we’re bored.

> we eat because we’re bored.

And because we're stressed. And because we expect to eat. And because our stomachs are empty. And because we have our thirst signal confused for hunger. And ...

I bet there are at least 20 distinct sensations that people feel as 'hunger'

Whether or not the realization that overeating is my problem helps me solve the problem is orthogonal to whether or not it's true. It is objectively true that I overeat. In my case, I believe I overeat because I have poor impulse control and I enjoy both the act of eating and the sensation of being stuffed with food. Furthermore I particularly enjoy greasy and carby foods, pizza particularly. If I ate less (or stuffe…

The additional shame I suspect you feel about your eating habits, likely leads you to binge eat more however - thats my larger point, it creates a negative feelings cycle that makes the problem worse. You probably binge eat to plug an emotional or stress hole, its literally a form of self medicating. Thats not something that willpower or blaming yourself can solve.

That's possible. But the fact remains that I overeat.

People in developed countries have become too accustomed to comfort. We need be accept a certain level of discomfort and pain. Embrace the suck. And most people with high BMIs didn't get that way eating steak and baked potatoes. In fact, if you live entirely on that diet it's quite difficult to get fat.

> if you live entirely on that diet it's quite difficult to get fat

I believe that for myself, being able to eat like a king from many different culinary traditions has been a major factor in my fat gain.

"Obesity is a major health risk, with junk food consumption playing a central role in weight gain, because of its high palatability and high-energy nutrients. The Cafeteria (CAF) diet model for animal experiments consists of the same tasty but unhealthy food products that people eat (e.g. hot dogs and muffins), and considers variety, novelty and secondary food features, such as smell and texture. This model, therefore, mimics human eating patterns better than other models." - https://pubmed.ncbi.nlm.nih.gov/33309818/#:~:text=The%20Cafe....

Yesssss!

So my diet is usually very strict. I will mostly only eat salmon, mackerel, oysters and mussels, and a lot of berries with some breads and rice. No plant oils at all and very low carb, but not no carb.

I only resorted to this diet because I had a series of metabolic disorders in my self and in my family and I also know my genetics. I have the changes to FADS1, FADS2, and CPT1A which make me much more sensitive to Omega 6 fats that most European Caucasians. See it turns out I have more Sami blood in me than I thought and so I am in reality more Inuit when it comes to what I need from my diet.

I most certainly feel most satiated and loose weight even when eating the same amount of calories when I am following this diet. I was a low fat vegan for five years in an attempt to correct my cholesterol, and I was a good vegan too, no junk food. But all it did was lower my HDL and barely reduce by LDL. (I was diagnosed with mild hyperlipidemia). After seeing my geteicss and changing my diet, my HDL rose over 35 for the first time in my life. Now it stays steady at between 50 and 55

Now I am only more sensitive to these fats. Meaning that anyone, even with non-Inuit genetics, will succumb to the higher levels of Omega 6 that course through the modern food industry if they over do it.

Your using Satiety Index method. An excellent method. https://optimisingnutrition.com/calculating-satiety/amp/

Understanding satiety is a powerful tool in managing hunger and health.

Very interesting! I've been reading up on nutrition recently and saw articles talking about this ratio, but they were focused on inflammation, not on body composition or hunger. tmjdev wrote: > If it was the ratio being studied, could you instead increase your n3 fat consumption?

This. It's a lot easier to increase n3's through consumption of chia seeds and nuts than it is to cut out n6's, because those are in most factory farmed meat and fat sources.

> It's a lot easier to increase n3's through consumption of chia seeds

It depends on your genetics. the genes FADS1 and FADS2 will dictate how much of those short chain omega 3 you can turn into the long chain omega 3, like EPA and DHA, which ate the reason for the metabolic reversal.

Also since Omega 6 and Omega 3 compete for the FADS1 and FADS2 activity, eating less Omega 6 will always help.

Yeah, there are defnly people guzzling fish oil on that assumption.

I would be cautious though -- it's a novel dietary regime, and seems likely to induce a lot of oxidative stress...

Certainly in mice it seems to.

https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3435540/

From that study:

> It appears of utmost importance in medical and nutritional practice to formulate and handle n-3 PUFA-rich foods or supplements with the greatest care to avoid any PUFA oxidation. This can be particularly relevant in patients suffering from acute or chronic diseases who increase their n-3 PUFA intake because of their reported health benefits.
