The mathematical model for BMI is flawed.
Body mass index =weight / height squared
@DrEugeniaCheng asks why is height squared?
"Humans are 3-D, not flat like pizzas"
"Rocket science is arguably simpler than weight loss"
wsj.com/articles/weigh…
@DrEugeniaCheng Stop it with BMI. Use weight circumference. It's a vital sign. An important consensus statement
nature.com/articles/s4157… @NatureRevEndo #openaccess
@DrEugeniaCheng @NatureRevEndo corrections:
1. Waist (not weight) circumference
2. Stop it with BMI fixation. Waist circumference is a better metric

Our new @ThaLancet Digital Medicine essay is especially timely
thelancet.com/journals/lance…
It's on #AI-assisted endoscopy w/ @tberzin, a co-author and collaborator in 3 randomized clinical trials @BIDMChealth
@tberzin @BIDMChealth Of the 6 randomized trials of #AI in medicine published to date, 5 are in #gastroenterology, using real-time machine vision during endoscopy. All of these were conducted in China.
@tberzin @BIDMChealth Unlike other deep neural networks for medical imaging, it requires real time assessment to detect an adenoma and decide whether a biopsy is indicated.
This video from Japan's @LPIXEL_Inc shows where the field is headed #AI

What is the longer term impact of #AI-algorithms that guide non-expert (uninitiated) humans to acquire ultrasound images?
1. Yesterday the @US_FDA approved the 1st system to do this for heart images (echocardiography)
statnews.com/2020/02/07/fda… @statnews by @matthewherper
@US_FDA @statnews @matthewherper 2. I used this system last month. Software directs the person imaging to the optimum spot for high-quality images and once there automatically records. Example loop:
@US_FDA @statnews @matthewherper 3. Such imaging can ultimately be done anywhere and by anyone, using smartphone-ultrasound as shown here, exemplifying a way that #AI can reduce global health inequalities.
Remote expert interpretation is now possible and eventually cloud-based algorithmic support will kick in.

Simple Tips to Gain Weight:

Take more meat, milk, yoghurts,fish and eggs; Also potatoes, yams, brown rice.
Eat more than three times a day.
Use bigger plates and try finish it.
Cook with more sauce & spices.
Try to rest more often.
Avoid stress and physically exhausting stuff.
While a good number of people are fat and overweight, actually a high number of people are underweight as well.

And just like being overweight, being underweight also has its problems both medically and psychologically.

Not everyone is happy being “small” or being underweight.
How do I know if I’m underweight?

It is based on what we call the BMI Body Mass Index. If your BMI is less than 18.5, you are underweight. And if more than 24.5, you are overweight and if more than 30, you are fat or obese, and if more than 40, your life is at risk medically.

FUPA this. FUPA that.
Since some of you are using this to glamorise obesity, above is a reminder of some medical risks involved.
I’ve seen a recent FUPA trend on twitter which has been utilised by some people as an avenue for obese people to celebrate obesity and even gather an audience to applaud them and wish for what they are flaunting.

Let’s be clear on something.
This is a medically dangerous trend.
I’m not here for political correctness or the worthless virtue signalling that wrongly misleads the gullible into thinking that good self-esteem is found in celebrating anything even absurd and clearly unhealthy trends, despite the proven medical risks that are present.

1/ Thread on understanding weight gain / loss and why mainstream guidelines & most doctor recommended diets are wrong. TLDR: Restrict *carbs* not *calories* to control your insulin levels. Use intermittent and extended fasting to reset your BSW (body set weight) #megalife
2/ The best book I have read that explains this topic in a way that everyone can understand is ‘The Obesity Code’ [1] by Dr Jason Fung [2]. For ‘real’ results Sam Feltham [3] [4] did a great self-study on equal calorie eating [5] [6].

🚨 Holy Smokes.
Let me repeat that: 4.2 MILLION currently uninsured Americans could get #ACA-compliant healthcare policies FOR FREE.

(yes, they'd have high deductibles, but they'd include FREE preventative services, such as, blood/drug screenings, mammograms, vaccinations, etc)
THREAD: Here's the full list of FREE preventative services (regardless of deductible) included with every #ACA marketplace policy (as long as it's done in-network): 1/

--Abdominal aortic aneurysm screening
--Alcohol misuse screening and counseling
--Aspirin use to prevent cardiovascular disease and colorectal cancer =
--Blood pressure screening
--Cholesterol screening
--Colorectal cancer screening for adults 50 to 75
--Depression screening

"Many pages of the official Ontario website show both a strong anti-fat stance and a heavy reliance on positivist claims and measures." (90)
BMI is touted as a direct measure of health. Dangers of yo-yo dieting are downplayed.
