New Weight Loss Maintenance Study Findings
3FC won't let me post the link, but if you google 'biological changes thwart weight loss efforts study finds' it should come up on the NY Times. this was JUST published too.
My question to those of you who have been maintaining for more than a year: Do you agree wtih the findings? How is your appetite? Are you always hungry? Do you find that yoru appetite or level of hunger has changed since the weight loss? If so, how? I have maintained a 30lb weight loss for almost 6 years now and have also been maintaining a 50lb weight loss for almost a year now. My appetite? I could eat all day long. Heck, I always have something in my mouth!! I can eat until I'm sick and I will want to continue eating. The only way that helps me maintain is to: Keep a detailed tracksheet of my activity, and what I eat every day. I have been very lucky to be able to eat anywhere from 1,800 to 2,200 cals/day for the last few months without gaining anything (at least not yet), but that is because I train hard. My motto is: if I want I eat I have to move....Right now I'm trying to lean down as I want to race a marathon next summer, so I have about 10lbs I want to lose. I know that by creating 250/300 cal/day defecit, I will reach my goal in late April, but its **** already on 1,700 cals/day nevermind anything lower. My body does like 125lbs though. A week or so before TOM I end up at 130 and then I go right back to 125...but I digress. I guess, we're like a bunch of recovering addicts. Always having to be on our toes and the likelyhood of us maintaining our losses has everything to do with us not being 'normal' like the rest of 'them'. Also, for those of you who have made it to the end of my post, another worthwhile blog to check out is "justmaintaining.com" She has some very interesting posts about the whole 'just maintaining' bit and she's a big sicence nerd, which I always like. good work ladies. keep it up! :) |
IMO, here is the key thing they gloss over (quote from NYTimes):

It's good information to have, but I'm not sure it's really all that valuable or even applicable. As for me personally, I am coming up on 6 years of maintenance next month. I don't think I'm any hungrier or less hungry now than I was when I was fat. I still struggle with my weight but it is more because I am an emotional eater and I love dessert than because my body is actually hungry. |
I believe that once you have been obese and lost weight (I'm not talking about 10 lb, much more significant than that) you will always have to be vigilant about maintaining it. It's not so much about hunger, IMO. Show me the obese person who got that way only eating when she was hungry? I didn't really know what hunger felt like, I ate so much for other reasons myself!
It's about what a fine line it is. You will gain weight overeating just a little teeny bit if you continue to do it over a sustained time. People who keep the weight off are vigilant about it and stay involved in the process. It doesn't keep itself off, that's for sure. |
While I think this study is a step in the right direction, I really wish they would look at participants who lost weight over longer periods of times through much smaller calorie deficits and exercise.
My average weight loss has been between 2-4lbs/month and I'm certainly not eating very lower calorie either (I haven't estimated recently but somewhere between 1400-1800 calories/day). I have to say that I feel full and if I don't feel full something's wrong with my diet. If I start feeling hungry all of a sudden I really look at my diet and change something (usually it's because I'm eating too many carbs and forget to combine them with protein or not eating my snacks regularly). I also started seeing a nutritionist and that helped a lot. Granted, I'm not at maintenance yet but I have been at this well over a year now and hunger just isn't an issue for me at the moment. Also, I've always had it in the back of my head that as long as I reach a healthy BMI I can always stop if I feel that I have to eat too little to maintain my weight. That's the next thing about having a range of weights to think about. ;) I definitely am interested in the leptin levels research but so far they just aren't doing it on slow losers who are doing lots of physical activity. I've also heard that things like DHA and multivitamins can help with leptin levels but I'm not sure how true that is. ETA: I would also like to know... how long were these participants overweight? were they exercising at all? what were their ages? how did they gain the weight in the first place? There are just too many variables left... |

And yeah, I experience "eat impulses" throughout the day. :devil: |
This is going to sound harsh and uneducated, but I find all these "studies" as just an excuse for people to throw hands up and say oh it's too hard to maintain, I'll just give up. As a wise maintainer once said, maintenance is hard, being fat is hard, choose your hard.
Am I hungrier? At first yeah, then I went through a stretch when I was significantly less hungry, now I'm hungry again. IMO, maintenance is work and it can be as hard or as easy as you choose to make it. How you reach that level of acceptance and balance is a personal journey we all have to take to figure out, much like the rock bottom we had to reach to decide to lose weight in the first place. I guess my point is I just find very little value in these "studies" because they're typically all flawed and really who cares what they found, I'm not going to stop working my a$$ off to maintain my loss because someone says my hormones or biology has changed and it's going to be hard. Sorry, I'm in a mood today:) |

Hope your mood has improved. Yeah, I take these studies with a shaker of salt. They just make me more proud of what I have achieved - and more determined to prove the naysayers wrong. ETA: Wow - ncuneo, I just noticed that you started at 268 lbs - way to go! :carrot: |

Certainly, someone could interpret the studies in such a way that maintenance is impossible but that is not the fault of the scientists doing these studies. Just like scientists who show a correlation between BMI (or waist size or waist to hip ratio etc) and health are not to be blamed for others insecurities when they hear that information. Most of it is how the media "sells" the results to the public. If these things bother you, don't read them. However, there is indeed value in better understanding the human body and how it responds to weight loss. Even if these studies do have quite a few flaws (as I mentioned above), they are a step in the right direction. If we can understand WHY maintenance is so hard we can also try help those who have lost weight keep it off. I agree that just because we know something is hard we shouldn't throw up our hands and give up but,+ on the other hand, it's important to know that it IS hard so that we're aware of what we're getting into. Telling maintainers that they just need to deal with the hard, unfortunately, isn't working otherwise we wouldn't have the poor maintenance statistics. |
It's a flawed study in that it subjects people to very low calorie levels and then observes that they want to eat more. Oh, really? Did we need a new study to tell us that? Look up the Minnesota starvation experiment--it found out all the same things.
Any time I read that researchers are trying to find "the cause," and that maybe a drug or a supplement might be the answer, I wonder who is funding the study. I suspect a profit motive. "Just take this pill for the rest of your life..." I'm just saying! There are many many studies out there on leptin, and at least one of them has shown that levels of leptin in the blood aren't any different in obese individuals than in non-obese individuals, which means supplementation isn't the answer. We all would like that magic pill, but it looks like the basic message is going to be the same for a long time: to lose weight and keep it off, one needs to watch one's food intake in some way. Jay |

Thank you nads84 and RedPanda both for pointing me to this. |

*Although it is true that leptin levels are higher in obese individuals. Quote:
Now, like I said before there are many unanswered questions here: - what about weight loss through diet AND exercise? - does time at the highest weight affect leptin levels? - does speed of weight loss affect leptin levels? - how much does genetic play a role here (are some people more leptin resistant than others?) They have found that leptin levels can also be associated to sleep and anxiety/depression so there are other factors involved here too. But to ignore the results all together? I have to admit I just don't get that at all. We seem to have stumbled onto a link between difficulty maintaining weight loss and leptin resistance, why in the world would you ignore that? :?: Nobody is telling you that you have to take a drug. NOBODY. But if it can help someone who would otherwise be prone to gaining back the weight (come on the statistics are something like 80% of the people regain the weight!) then I'm all for it. We're not talking about a magic pill here. We're talking about people who have already lost weight in a healthy manner and they're still struggling. There's something wrong when the stats are this bad. Now certainly this isn't going to cure your emotional problems and if that is the reason you gained weight in the first place that is something else. But it is HARD to be hungry all the time. If you could take that part away? Well, I just don't understand why you'd ignore that. |
I think I'll wait for the 5-year, double-blind study that actually provides something other than hypotheses or guesses. In the meantime, I'll deal with the situation as best I can.

And isn't that what we're all doing? God only knows if this will be figured out in 5 or 50 years. Waiting around for a cure is silly. Instead we deal with what we have for the time being. :shrug: |
Re the use of leptin to help weight-reduced individuals to keep the weight off, there's a rather depressing article about it here:
