Watch "The mathematics of weight loss | Ruben Meerman | TEDxQUT on YouTube

I was confusing this video with a similarly titled video that I saw years ago that claimed that the mathematics of weight loss was just calories out versus calories in.  Although technically true, weight loss is more complicated, with certain foods like sugar being worse than others.  Sugar actually stimulates appetite.   In addition, our gut flora send signals to our brain to stimulate our appetite for specific foods.  Those bacteria get hungry, and different bacteria prefer different types of nutrients.   Eating healthy foods adjusts your gut bacteria to that diet.

This is where probiotics might be helpful.




In addition, I just read about "obesogens", which at first sounded like a joke to me, which are chemicals in the environment that promote obesity.  https://www.ehn.org/chemicals-in-everyday-products-are-spurring-obesity-warns-a-new-review-2657191067.html

In terms of the chemistry of metabolism, this video is scientifically interesting.  However, it isn't really news that we lose mass as we breathe out carbon dioxide.

Study reveals some brain changes, even in mild COVID-19 | CIDRAP

The study authors noted that the imaging differences between the two groups were modest, at about 2% of average baseline values. The typical annual loss of gray matter each year due to aging, the researchers said, is 0.2% to 0.3%.

Cognitive tests identified differences between COVID-19 survivors and controls, including a significant increase in the time taken to complete Trails A (numeric; 7.8%) and B (alphanumeric; 12.2%) of the Trail Making Test in COVID-19 participants. These results held true when excluding the 15 hospitalized patients (Trail A, 6.5%; Trail B, 12.5%).

"The infected participants also showed on average larger cognitive decline between the two timepoints," the study authors wrote. "Importantly, these imaging and cognitive longitudinal effects were still seen after excluding the 15 cases who had been hospitalised."

Not all COVID survivors have brain changes

In addition to the modest COVID-19 effect, the study authors noted that the statistics represent an average effect, meaning that not every COVID-19 survivor will experience brain changes.

Opinion | What I wish I’d known when I was 19 and had sex reassignment surgery

I may well have transitioned even after waiting a few years. If I hadn't transitioned, I likely would have suffered from the world in other ways. In other words, I'm still working out how much regret to feel, but I'm comfortable with the ambiguity.

What advice would I pass on to young people seeking transition? Learning to fit in your body is a common struggle. Fad diets, body-shaping clothing and cosmetic surgery are all signs that countless millions of people at some point have a hard time accepting their own reflection. The prospect of sex can be intimidating. But sex is essential in healthy relationships. Give it a chance before permanently altering your body.

Most of all, slow down. You may yet decide to make the change. But if you explore the world by inhabiting your body as it is, perhaps you'll find that you love it more than you thought possible.
