More About Obestatin

Yesterday, I had every intention of staying on track. Here is what I ate:

no fat yogurt, 2 points
2% milk, 3
hard boiled egg, 2
orange, 1
baby carrots, 0
Weight Watchers frozen lunch, 5
granola bar, 3

Going into dinner, I had 15 points left. I planned to eat a small potato, 1 point, and broccoli/cauliflower--0 points-- and I planned to have 6 oz of left over turkey for 6 points. That would still leave me with plenty of points for another piece of fruit or popcorn if I needed it.

My dh was grilling kielbasa. Normally, that's not a food I crave. My daughter and I had a doctor's appointment yesterday and we came in at about 5:30. I could smell the kielbasa cooking and my mouth started watering. Dinner was ready and suddenly I wasn't going to take the couple of minutes to get the turkey out and nuke it. I sat down and had like 20 points worth of kielbasa! And I wasn't even really thinking about it or savoring it, either! :(

I need this suppressant thingy...yesterday!

Appetite-Suppressing Hormone Discovered
By Ed Edelson, HealthDay Reporter

(HealthDay News) -- There's a new entry in the field of weight-controlling hormones, a finding of potential importance to the millions of Americans trying to lose weight without giving up their zest for eating.

The Stanford University researchers who discovered it have named it obestatin. It acts to suppress appetite, and its commercial possibilities are noted by sponsorship of the research by the pharmaceutical company Johnson & Johnson.

Obestatin joins leptin, melanocortin and ghrelin, hormones identified in the last few years as acting on appetite and weight. So far, work with those molecules has not produced the hoped-for cure for obesity.

The obestatin discovery comes with a couple of twists. One is that it's produced by the same gene that produces ghrelin, which acts to suppress appetite. Another is that major credit for the discovery is given to Charles Darwin's theory of evolution.

The principles of evolution led to identification of obestatin, said Aaron Hsueh, a professor of obstetrics and gynecology at Stanford, in whose laboratory the work was done. He also credited the information gathered by the Human Genome Project, which produced a complete human gene map.

Hsueh and his colleges used human genome data to study small-peptide hormones, which are active throughout the body. Specifically, they looked at the receptors for those hormones -- the cellular molecules to which the hormones are attached when they go into action. There are about 300 such receptors, of which 100 had no known hormone partner.

The search for missing hormones was narrowed by focusing on receptors that have been around for hundreds of millions of years and are found in many species. One of those receptors is for ghrelin. Further studies showed that ghrelin actually had another protein tacked on to it -- obestatin.

When the researchers injected obestatin into rats, "to our surprise, we found that treatment with it suppresses food intake," Hsueh said. And so, he added, "it could have potential as an appetite-suppressing drug, by injection. Or it might be possible to deliver by nasal spray. It also allows us to screen for new drugs that might suppress appetite."

The study findings appear in the Nov. 11 issue of the journal Science.

But Matthias Tschop, associate professor of psychiatry at the University of Cincinnati, and co-author of an editorial in the journal on obestatin, is sounding a note of caution.

"The effect of obestatin on body weight seems to be relatively limited," Tschop said. "Also, it might cause some sort of illness or nausea that causes a decrease in food intake."

The effect of obsestatin was discovered in research with rodents, Tschop noted. "The most obvious question is, does obestatin work in obese animals?" he said.

And the business of weight regulation is complicated, Tschop added. "There are many other players involved," he said. "And obestatin may have many other functions. For example, it could regulate physical activity."

But with all those caveats taken into consideration, the discovery of obestatin is "a step in the right direction," Tschop said.

Anti-Ghrelin

This is what I need...if it works! Since finding my daughter's encouraging notes, I've been forcing myself to stay on the path and actually managed to lose 3 pounds! My daughters and I joined a gym (with a pool, a must because of my ankle) on Friday and are looking forward to getting some exercise. The biggest drawback is that it's 20 miles away...but this is something I must do. I just wish I didn't feel half starved most of the day. How much was I really eating?

This has been my typical day since I last posted:

6 oz. non fat yogurt
1 cup 2% milk for my coffee during the day
10 baby carrots
1 orange
1 apple
1 Weight Watcher or Healthy Choice lunch, usually 250 calories or about 5 points
6 oz of protein for dinner
vegetables
no-fat popcorn, 1 bag

All that adds up to my allowable 31 points per day. I get 35 points extra per week and believe me, I do use them up.

I drink water to the point it makes me sick instead of filling me up.

How do they do it on Survivor?

Encouragement

My 17 year old daughter left me messages of encouragement on each page of my food diary, how thoughtful and sweet! And it strengthens my resolve not to give up because she is along for the ride now too.

My darling husband (dh) TB found an online article about binging from the APA. At first I felt very discouraged, thinking how hard a battle I've been fighting only to suddenly binge thoughtlessly and without control. The article does help me understand why binging happens and it's not totally hopeless--as long as I keep away from the junk and don't "diet" (deprive myself).

Here is what I have to figure out: how to combat hunger pangs after I've had normal sized portions of stuff. Example: the night before last, I had eaten up to my points except for having an apple. I had that as my snack.

It wasn't long, though, before I suddenly felt ravenous. I craved my old enemy, cheese, and it so happened (unfortunately) I had some in the house. Well, I'll just have an ounce, I said to myself. I sat back down to watch TV after having the cheese and I was just filled with this overwhelming desire to get "just one more ounce". Well, I ate about half the block (4 oz) of cheese before I stopped myself.

So how do I deal with that?

Stumbling Badly

I seem to be having a lot of trouble getting my mind around this Weight Watchers program. I have to admit the last time I joined, with Michele and Linda way back when, I had the same problem -- an attitude about the program. Is it because I've tried Weight Watchers so many times? I tried to tell myself to follow the program and get to maintenance (which I've never done before) but for the last 3 or 4 weeks, all I've done is gain weight. So now I'm checking into other programs. One is Curves and the other is Global Fit. Curves would be great, it's very convenient but I'm not sure how my ankle would hold up. Global Fit gyms have pools--but they're not women only. Have to visit each place and ask questions!
