Can you guys comment on this TEDTalk? It's a short lecture by neuroscientist, Sandra Aamodt (University of Rochester, School of Medicine) on why it's extremely difficult to maintain weight loss:

It is discouraging to know that most of us who do lose weight can't keep it off long-term. I'm one of those people who lost a lot in the past and gained all of it back plus 40lb more (total of about 90lbs). I still hate myself for letting that happen. My sad story isn't unique at all unfortunately. If you talk to people who struggle with weight, pretty much all of them have gone up and down. I've only met a few people in my life who have maintained long term and don't struggle with food/exercise anymore. I admire those people and want to be like that. Even though I have lost a good amount of weight (again), I still have all the emotional hang ups about food, eating, body image, and exercise. I don't know how to work through it.

Erm that's depressing.
Please can some people who have lost weight and successfully kept it off please reassure me!0 -
She didn't even touch upon the speed in which you lose weight because that has a huge effect on hormone levels that effect hunger. She also didn't touch on body fat overshooting that occurs when someone finishes a diet. Adaptive thermogenesis is determined by the size of the energy gap you create with your calorie intake vs your calorie burn. An abrupt and large calorie deficit held for a long period of time will slow your metabolism, and binges along the way will slow fat loss, but not prevent your metabolism from continuing to slow. When you lose weight, especially when you lose weight fast, leptin levels change and hunger increases. When you get to your goal weight and start eating at maintenance, those leptin levels are still making you hungry and you have the tendency to over eat. This is when people usually gain the weight back, except the leptin levels take a while to get back to their pre-diet levels, so people often shoot past their original weight and gain even more fat. If you lose weight the proper way, you can absolutely keep the weight off. Don't get discouraged. The absolute best way to lose weight is to eat the maximum amount of calories a day that you can that has you still losing weight, aka lose weight very slowly. Your metabolism will slow, but not at the same speed at which it would if you had a large calorie deficit. If you stop losing weight, you just lower your calorie intake slightly and continue. If you do this instead of using a large calorie deficit, then your metabolic capacity will be higher when you reach your goal weight, then you should reverse diet until you reach maintenance so that you can have adaptive thermogenesis work in your favor as you increase calorie intake.0

I lost ~35kg about 5 years ago and have maintained that loss with no problems :-). Am back now to lose those last few kgs to get to my ideal racing weight :-), it can be done. I do think you have to be as mindful about how you eat/exercise when maintaining as you were when losing though (or I did anyway).0

The study she based her talk on is at motivatedandfit.com/wp-content/uploads/2010/03/Diets_dont_work.pdf
The lady isn't really a published scientist, she's a "science writer" - like Gary Taubes.

struggle with exercise? That's an interesting observation...
I didn't have an obesity problem when I regularly did judo or ice hockey. It was only after I quit ice hockey that I became obese for the first time.
Humans are not meant to be sedentary... so it can't really be any surprise that many people who are not physically active are going to be in a lifelong struggle against obesity. We live in an environment that makes it very easy to become obese, in that we can get food without exerting ourselves at all and get it in near enough unlimited supplies.
If you give apes in zoos an unlimited amount of food and don't make them exert themselves to get it, they become obese too. So yes it will be a lifelong struggle for many people in our society against obesity, because we've basically done the equivalent to ourselves of what zookeepers are advised not to do for apes, and made it too easy for ourselves to get food. There are many ways to get around this, such as taking up recreational activities that we can get sufficiently involved in to be able to burn the equivalent amount of calories our palaeolithic ancestors burned in acquiring food while viewing it as fun and recreation, not as a chore. We can organise our shopping, food storage and eating schedules so we don't end up mindlessly consuming way too many calories. There are all kinds of things we can do, one crazy idea that would probably work is for all office computers to be run on a dynamo whereby it takes 30 mins of exercise machine effort to power each worker's computer for the day. I'm sure there are many other ways around this. But the fact is that we've made for ourselves a civilisation where life is basically too cushy for the wealthier classes within it (looking at it on a worldwide level where wealthy = having readily obtainable food - even most poor people in the west can get enough food to regularly overeat) and so we get fat. Surprise surprise!
So this thing of long term maintenance being hard.... well avoiding becoming fat is hard in our society... it's not a problem of maintenance.... it's a problem of avoiding obesity altogether, i.e. avoiding becoming obese for the first time and avoiding becoming obese again after losing the fat from the previous time(s) you became obese.... the environment, habits and lifestyle that got people obese the first time will get them obese again if they don't change it..... you can't rely on willpower to see someone through for their whole entire life.... we have to change our environment, lifestyle and habits. We need to do the same thing that zookeepers do when they put more things in the apes enclosure for them to climb on and hide their food.... only the human equivalent, i.e. find ways to make ourselves want (or even better, need) to be physically active and find ways to make ourselves limit food intake to the amount of food we need to be healthy (physically and mentally healthy) that are going to be able to easily stick for life. Sometimes it can take a while and some trial and error to find how to do this in a way that works for you, but it is pretty much the only way to do this while also keeping mental health intact.0 -
I lost 40 pounds in a year and maintained for two years. Recently lost another 5-10.
I lost the weight slowly and not all at once. I would take a break after 15-20 pounds to maintain/plateau before I kept going.
Obviously this is a slow route but it's worked for me.0
