Treating obesity: One size does not fit all

Analyzing data from more than 2,400 obese patients who underwent bariatric weight-loss surgery, researchers identified at least four different patient subgroups that diverge significantly in eating behaviors and rate of diabetes, as well as weight loss in three years after surgery.

Daily Weighing may be Key to Losing Weight

Researchers identified several categories of self-weighing adults, from those that weighed themselves daily or almost daily to adults who never used at-home scales.

They found that people who never weighed themselves or only weighed once a week did not lose weight in the following year. Those that weighed themselves six to seven times a week had a significant weight loss (1.7 percent) in 12 months.

Yes, I weigh myself almost every day.

Yes it’s been over 40 years since I lost 200 pounds.

Yes!

No consistent evidence of a disproportionately low resting energy expenditure in long-term successful weight-loss maintainers

Conclusions

We found no consistent evidence of a significantly lower REE than predicted in a sample of long-term WLMs based on predictive equations developed from NCs and OCs as well as 3 standard predictive equations. Results suggest that sustained weight loss may not always result in a substantial, disproportionately low REE.

I feel so much better now.

 

Early-life obesity impacts children’s learning and memory

A new study by Brown University epidemiologists found that children on the threshold of obesity or overweight in the first two years of life had lower perceptual reasoning and working memory scores than lean children when tested at ages five and eight. The study also indicated that IQ scores may be lower for higher-weight children.

“Excess early-life adiposity was associated with lower IQ, perceptual reasoning and working memory scores at school-age,” Li said.

The authors pointed out that the sample size of their study was limited and that further studies should be conducted to confirm their findings. Future work could also investigate the impact of early-life weight status on school performance, attention-deficit/hyperactivity disorder diagnoses and special education use.

If these study results hold up in future studies then I’ll know just what the hell happened to me.

 

To Weigh or Not to Weigh

The National Weight Control Registry has published several studies on the habits of those who have successfully achieved and maintained significant weight loss over 10 years (4, 5, 6, 7). Their findings are based on the tracking of over 10,000 individuals through detailed questionnaires and annual follow-up surveys designed to identify behavioral and psychological characteristics and strategies used to maintain weight loss. 75% weigh themselves at least once a week.

Here’s a short literature review on weighing habits in the processes of losing weight and maintaining weight loss.  Read the source article here.

I completed my annual National Weight Control Registry survey this morning.

For the first time in a very long time I reported a weight loss since the last follow up.

When I tell people I’ve lost 200 pounds they are always surprised and ask how I did it.

Well, you’ll just have to buy the book when I finish writing it.

Binge-eating mice reveal obesity clues

For example, when offered chocolate for just one hour per day, the animals will compulsively ‘binge’, consuming as much chocolate in one hour as they would over a whole day if it was continually available. They also showed inflexible behaviours, similar to those seen in addiction, choosing to wait for chocolate while ignoring freely available standard chow. Yet, at the same time, the chocolate did not seem to satiate hunger as well as regular food.

The team found that animals on the high fat or chocolate diet also changed their daily routines. They were more likely to eat during the daytime — mice are usually nocturnal and feed at night — and they ate shorter more frequent ‘snacks’ rather than larger, longer-spaced meals.

We had friends over for dinner on Saturday.  While at the store shopping for provisions I saw some gelato on sale for 99 cents.

$0.99!  The only flavor on sale was chocolate.  I bought some.

The next night I had to have some chocolate gelato.  Because it was there!

The mice have proven what I already know.
