Evidence that increased BMI causes lower mental wellbeing

Stay healthy, GAF!

Results suggested a consistent causal effect of higher BMI on lower mental wellbeing. There was little evidence that the other physical health traits were leading to less happiness and life satisfaction. The same pattern of results was seen in a follow-up analysis using the UK Biobank cohort of over 300,000 individuals aged 40 to 70 years old. Here the authors were able to look at different aspects of life satisfaction and found that the key impact of higher BMI was on lower satisfaction with health. They were also able to show that the effect is present from age 40 through to age 70, and in both men and women.

When testing whether mental wellbeing caused any of these physical health traits, the authors found little evidence for a causal impact in that direction, but this analysis is limited because there are so far fewer genetic variants for mental wellbeing. As research uncovers more of the genetic variants associated with mental health traits, researchers will be able to test this direction of effects more thoroughly.

I do everything well (I'm 32):
- I have a good BMI.
- Good fat %.
- Do not drink alcohol, or do drugs.
- Not taking any kind of medication.
- My sugar intake is controlled (and no soda or sugar in my coffee/tea).
- Sleep 8-9 hours a night.

YET

I'm getting all these symptoms/conditions that typically older people get:
- A hemorrhage in my brain at 29.
- Signs of early onset dementia.
- Skin tags on my neck.
- A spermatocele.

Imagine if you didnt take care of yourself.

There was a study linking education level and happines claiming that the less education the more happy people are.

Point is just because something correlate does not mean effect of it is actually not needed. People who take care of themselves usually are way more self-conscious about themselves while it does indeed increase strees for some people at the same time it provides benefit of getting better sex partner, better money situation, live longer etc.

Stress is good. It is our basic mechanism to poke us in head telling us that we do something wrong and we should do better. Just like anxiety, anger and slew of other emotions.

Difference you are lacking is that with high fat amount you would get additional party poopers you didn't get because you kept yourself in shape. Just because you take care of yourself it doesn't mean you can't have cancer or die at 20 from stroke or hearth failure.

My grandfather is uber alcoholic that gets wasted almost every day. Dude has 85 years and aside from minor problems with legs he is completely fine. But you won't see me claiming that i should follow his "diet" or something. Genetics are far more important to when you die than almost anything you do in life, still that doesn't mean taking care of yourself don't have impact on it or your life in general.

I've never heard of this mendelian randomization technique, from which you supposedly can infer causation. I'm skeptical. The technique itself rests on correlational research. And research into the genetic determinants of mental health is not very advanced, with lots of limitations.

It's also worth noting that the main contributor to "lower mental health" is lower dissatisfaction with physical health. In other words, people who have larger BMIs are less satisfied with their bodies. No kidding.

They also don't give a sense of how large this effect is (effects often reach statistical significance without reaching clinical, aka real-world, significance), nor where the BMI cutoff would be.

In general, it's also helpful to remember that BMI is not a very good predictor. It is used by researchers and medical people because it is very simple to calculate, and that's about it.

I don't think the study itself was very solid. Lower mental health and lower satisfaction based on self-reflection is -- by definition -- highly subjective.

That said, we know that obesity causes health problems, which invariably lead to stress on your mental fortitude. Having extra body weight also interferes with a proper metabolism and your body's ability to regulate that metabolism. Your insulin sensitivity goes down, requiring higher amounts of insulin in the blood. Insulin itself is needed to convert stored glycogen into usable energy, so as your cells become less and less insulin sensitive they have a harder and harder time producing energy. That includes energy needed to make your brain function. So if you're fat, then your insulin balance is out of whack, no questions asked. It can be corrected with diet most of the time, but by definition if your body is hanging on to too much body fat then it is in a state of insulin abundance.

High insulin also predisposes your body to rely on one type of energy (glycogen). In a natural state, we use a mix of glucose and ketones for our energy. We can "train" our bodies to rely to much on glucose which is the actual source of "hunger cravings" a few hours after a meal: you aren't actually "hungry". Rather, the glucose levels in your blood is dropping and your body is upset it doesn't have an easy source of energy. Unless you are actually diabetic, there is no such thing as "keeping my blood sugar up". Such an argument is identical to a smoker claiming they need to "keep their nicotine level up" or a pothead claiming they need to "keep their THC level up".

Higher insulin and higher body weight also correlate with a higher level of the hormone cortisol. Cortisol is helpful in emergencies but otherwise dangerous to have in our bloodstreams in high levels. High cortisol has a lot of negative effects on the brain.

So, I'd say the conclusion was correct, but the method used to "prove" it was flimsy.

Old study, but it makes sense to me.

People with lower BMIs tend to exercise more. Exercise reduces stress, and releases happy chemicals. Unless you're ultra jacked and BMI doesnt apply to your body any longer.

I'm finally back in the normal range. The high end of normal but I will keep on with what I've been doing this far. Seems to be working. More energy, less fatigue, happier overall... lower BMI.
 
when i'm 10 or 15 pounds overweight i feel that shit, you feel like a different person

anxiety

the world/people treat you differently

i've always described it as "tuning into a different radio station"

that's why when people shed crazy weight they feel like gods

Anyone who has lost some weight could tell you this. I know for me it was like a fog that got lifted in my brain. And I slept better which helped of course. And I had less weird random aches and pains, which helped my state of time. Then I realized I pretty much felt like shit 100% of the time before but it was normal.

Higher BMI causes more stress on the body, so it’s not too surprising that it would affect mental health in some way or another as well.

Makes sense. Kinda a pointless study. One you are dealing with your body's perception in relation to others (shaming, public herd mentality), but you also have a PHYSICAL obstacle to good mental health. Your body is working way harder to maintain, and you lack things like endorphins that come from physical activity. And a host of other things. Sedentary lifestyle... etc.
 
Most people are fat because they have poor mental health.

It should be obvious, but with the recent ‘fat acceptance’ and ‘healthy at every size’ idiocy the more evidence like this there is in the world the better.

I can sure as hell vouch for the fact that eating right, exercising daily and spending time being active outdoors makes me feel physically and mentally far better than any time I get stuck eating crap and being sedentary, which is usually around Christmas, Easter and birthdays in my family.

Slobbing it up can be fun for a day or two, but your body quickly lets you know you’re treating yourself like crap.
 
It's just so hard for me to imagine that the biggest issue with my body could be solved by eating less and then not simply doing it.

I wish all things going wrong in my body were so easy to get rid off..

Absolutely. I was frequently miserable and quite bitter than I was overweight. Being physically fit and healthy certainly provides a lot of mental wellbeing to me.

When I was in the best shape of my life, I definitely had less mental weirdness than when I wasn't, for whatever that is worth.

It blows my mind that people still don't understand the importance of physical health has on your mental state. It just seems like the most obvious thing even a 5 year old could figure out.

Because there is a direct link between exercise and brain health. And I think it's mainly aerobic exercises.

Hold onto your panties
I was 320 lbs and suffering a mess of depression from 2013-2016. When I left the U.S., met my wife, and became a Mexican citizen (in 2017); I decided to better my health for my wife. From April 2017 I started a permanent diet plan (bonus: fresh natural food is affordable in Mexico) and by 2019 I was down to 158 lbs. I'm about 152 and holding right now. In 2014, I nearly entered a program to start lap-band surgery...It's much better to just adjust to not eating junk and living healthier. Those who do get surgery...many relapse.

BMI is utter nonsense. Measure your body fat instead. Eat healthy, exercise often and live happy.

When all else fails, try a strict elimination diet as a last resort. Try removing oxalates, for example. You may have an autoimmune disorder.
