Persistent Metabolic Adaptation

Sunday 10/6

Straight to the point. My BMI is back in the overweight range. I was hoping for a random uptick with a gradual return to my 173-175 range but it has not happened. I now fluctuate between 177 and 178. Another pound or two and my skinny jeans won’t fit anymore. So the research geek in me took over. I wanted to know why I’m gaining weight after years of keeping my number down. Lack of enough exercise was an obvious reason. But I also felt my metabolism changed (again) so down the rabbit hole I went. The deeper I went the dots starting connecting.

I recall reading somewhere that successful weight loss maintainers changed their diets multiple times in their lifetimes. I found this to be true in my case. Remember The Biggest Loser television show? I found this fascinating study Persistent metabolic adaptation 6 years after “The Biggest Loser” competition https://doi.org/10.1002/oby.21538. Fascinating because the participants with greater long-term weight loss also had greater ongoing metabolic slowing. It appears my metabolism is slowing down not just from age but also from the fact I’ve maintained my weight loss for a long time.

And if this wasn’t bad enough I stumbled upon Metabolic adaptation is associated with a greater increase in appetite following weight loss: a longitudinal studyhttps://doi.org/10.1016/j.ajcnut.2023.10.010. Lose weight. Appetite increases!

The universe opened up her secrets to me. I need to change my diet (again).

Take Home Lesson

Long-term weight loss requires perpetual behavioral adaptation to offset persistent metabolic adaptation.

In plain English, I have to eat less or I’m screwed. Because I already know I’m in the one third category.

About 10 percent of older people living in their own homes do not eat enough and one-third of people over the age of 65 eat too much. More than half of older people in hospitals or nursing homes have malnutrition (poor nutrition or diet). – https://www.healthinaging.org/a-z-topic/nutrition/basic-facts
