What do you think about the "dad bod"?

Well, obesity doesn't cause diabetes. Rather diabetes and obesity tend to be caused by the same thing which is why diabetes ends up being positively correlated with obesity - both are caused mostly by a continuous over-consumption of glucose.

And with regards to overweight people in BMI terms dying later than underweight people, yeah, if you lift and thereby are overweight because of muscle and not fat then your health outcomes are going to be even better. I suspect most of the thing with overweight people dying later are to do with them being able to better handle "treatments" such as chemo which would basically kill underweight people.

It's probably optimal for your health to stay at normal weight BMI, or overweight with lots of muscle until you're about 65 in which case being overweight without muscle or obese with muscle is probably optimal.

Insulin resistance i.e. the progenitor to Type II diabetes and often subsequent Type 1 is caused by obesity in the overwhelming number of cases.

Having had chemo - the ideal starting weight is within the healthy bf%. Too fat and too thin leads to problems. Being overweight isn't optimal for anything other than being overweight.

How on Earth can obesity cause anything? It is a symptom not a disease.

It's defined as a disease in america and other places + it's regarded as an inflammatory state.

There's 3 main theories that I'm aware of

- Lipotoxicity in myocytes interfering with insulin signalling
- Pro-inflammatory state - release of proinflammatory molecules leads to altered insulin signalling
- Adipokines - decreased adiponectin when in an overweight state leads to decreased insulin sensitivity

Insulin resistance leads to more insulin being needed, which eventually leads to Type 2 diabetes, it basically means that the body can't produce enough insulin to reduce glucose levels to their normal levels. This further leads to Type 1 diabetes from beta cells in the pancreas being unable to produce insulin as they become exhausted.

All that "overweight" in normal boring terms means is high BMI. That is, weighs a lot for their height. Increasing in weigh does not causally result in increased insulin sensitivity is my point. It is something that is correlated with increased weight that does. For example if I am very average weight and start weightlifting and eating more and actually gain weight but decrease in body fat percentage since most of my weight gain was muscle then will, by necessity, I have became more insulin resistant?

Another way of looking at it - Are underweight people the least insulin resistant of all people by necessity?

Obesity is a "state" of the body or a "property" of it - it is not an "action" the body undertakes therefore it cannot cause things to happen within the body, it can only be correlated with them.

Become fat - become insulin resistant. It's not a casual relationship, it's a real measurable one. Whilst not every overweight person is insulin resistant off the bat. Those who are overweight are at a greatly increased risk of getting diabetes via the mechanisms I described above of insulin resistance. Consider us lucky as in other species, e.g. the horse - any horse obese for 2 years 100% has strong insulin resistance.



The honest answer is I don't know as I'm not a specialist in the area, a medic or two around might be able to answer that better than I would be. But having very low bf comes with it's own problems, far more than worrying about how insulin sensitive you are despite it standing to reason.



Adipocytes are cells like any other, in greater number they change the bodies dynamics entirely. It is not merely a property. As a lecturer put it to us "Obesity is a chronic inflammatory state", it has real biological changes and hence the increased risk of diabetes, CV disease etc.

Semantics. I'm talking about causal relationships based on "overweight" merely meaning weighing X at height X. I'm not talking about the quantities of specific cells and so on.

You see, the reason why this is important is because otherwise people just consider calories and don't care about actual micro-nutrients or even macro-nutrients! Ahh I'm not overweight since I don't eat a lot of food so I'm perfectly healthy. Whereas in reality so long as your mass is not coming from specific types of unhealthy (and the notion of "unhealthy" anything is something else to rant at) cells it isn't a priori true that you are less healthy.

Overweight according to BMI makes many athletes overweight. And yes, I wasn't necessarily talking about BF%.

If you don't think obesity can cause other diseases, then you don't understand obesity.

So you're not talking of being overweight i.e. has too much fat? Ok seems legit.



There are fat vegans in this world, they're no more healthy than they're omnivorous overweight friends



Which would be why BMI is completely negligable for the fit, healthy and muscular. Overweight =/= being muscular.



Exactly this

If you don't think obesity can cause other diseases, then you don't understand obesity.

Kay. I think the whole point has just flew past both of y'all heads so I'm just going to drop it.

You had a point?

Nobody got it?

Oh well.

Wait, was it a joke?
