What causes failure?

Human nature. Honestly.

We evolved over thousands of years to maximize survival. We seek out calorie dense food to pack on the pounds so that we can survive the long winter months and times of famine when food used to be scarce.

Unfortunately, we live in an age where calorie dense food is easy to find and afford. Famine doesn't exist... at least not in 1st world countries.

Add emotional and social eating to this problem... and... many of us (30% of the USA, at least) tend toward fatness.

It is relatively easy to be careful and diligent for a short period of time... but it is very hard to be diligent over a life-time. And for those of us who have an evolutionary advantage during times of famine >.> and.... well... its really easy to slip up, give in, stop counting (who wants to count calories forever????) and fall back on old habits and behaviors.

I think Acogg hit it right on the head. People think they are done. It's a life time change. You have to enjoy the new portions, food and exercise. I know I was lazy and didn't take into consideration how much I was eating. That's how I ended up at 317. I didn't eat really bad, although it wasn't good either. When I get lazy and don't watch portions, I usually blow it. But I've learned too that I pick myself up at that point and start over. I now know what works and when I'm lazy. I can' afford to be lazy any more.

Yep. I've been on maintenance since May of 2012 and in some ways, it's harder to maintain than to lose. It was exciting to lose weight and get all the compliments but I have to find new ways to keep my head in the game.

I'm not a yo-yoer by any means but I did lose once before and gained much of it back. Not all, but a lot of it. It's because when I hit my goal I thought I could quit tracking my food and I slacked off on exercise. I don't track as meticulously as I used to and will take entire days off from tracking but I'm always conscious of about how many calories I've had each day.

no discipline.

Lack of time, no strength training program, only "kind of" wanting it. Not wanting it as bad as going out, drinking, having cheat days... etc

In my case I didn't lose ALL the weight and then gain it back, but I did gain back quite a lot of what I had lost (over 20 pounds) (my ticker used to read 59 pounds lost :sad: ) due to illness. I was rendered basically immobile. I had zero appetite for over a month and barely ate, which was followed by medication that made me suddenly RAVENOUS. I've never been so out of control hungry in my life. The combo (being completely lethargic and not hungry, followed by extreme appetite) had a huge impact on my weight. I'm sure my metabolism has slowed to a crawl during my sickness, and then was assaulted by a ****load of calories.

Stuff happens.

It's hard to keep up with new days-old/weeks-old/months-old habits when trying to change years and years of bad habits.

Life happens. It's not a failure unless you stop trying.

Hi Jaycie and good question.

IMHO taking your eye off the ball and going back to bad habits can cause failure.

It is so, so easy to fall back into a bad routine.

I wasn't sure where to post this question, so I figure I would ask those that are trying to maintain. Lately I have seen several people posting things like "Back to MFP again". I've seen a lot of people on here talking about how they lost weight and then gained some or all of it back so they are back on MFP. Why do people fail? Right now I have the drive in me to lose weight. Once it is lost, I don't want it back. What makes maintaining hard? What can I do to prepare myself better?

I think it's not planning for lifelong maintenance that leads to falling off the wagon. It's great to reach all the target numbers but pointless if this doesn't become a sustainable way of living.

complacency.

losing focus

stop following the path that got you where you wanted to be
