Amen to what everyone has said here...
I think I can say after all these years - it's a matter of RETRAINING your thought processes (aka lifestyle changes) and getting out of the Diet Mindset (where the thought is "I'll eat like this for X amount of weeks or months, then stop when i get to goal").
Regarding "eating normally" - whether you will never be able to 'eat normally' again and so on. What DOES 'eating normally' MEAN anyway? I think the definition of "normal eating" has really been skewed big time since 1950 or so (after WWII, when convenience foods/fast food restaurants came into being combined with a more sedentary lifestyle as labor-saving devices were invented and introduced, and existing ones improved...not to mention the advent of television and people moving to the suburbs and away from established downtown areas within walking distance, which forced the population to rely on their vehicles to drive to work or to shop...). "Normal Eating" in the US now anyway, seems to mean lots of fast food, relatively few fresh fruits or vegetables, HUGE portions (I have an old cookbook from the late 1940's with a chapter titled "Cooking for Two" meant obviously for the newlywed wife with no children - the portion sizes are MINISCULE and would probably be considered "Cooking for One with No Leftovers" today!).
When I was growing up, McDonald's was considered an occasional treat - when I was 7 or so, a McDonald's meal would consist of a regular hamburger, half an order of fries (there was only ONE size back then...the one in the white paper bag) and half a chocolate shake (also only one size back then) and that was enough for me and my sibs. I don't spend a lot of time at McD's these days, but it seems like every time I pass by one, I see kids around the same age I was - 6 to 9 years old - dining on MUCH larger portions - we're talking a Value Meal with a Big Mac and large fries and a shake
is this "normal" nowadays? Where the "Mighty Kids Meal" isn't considered enough food for a first grader??
Personally, I think the way I strive to eat now is NORMAL. Maybe if I was living in 1910, or even 1920, I would probably not even worry about eating too much, because I would be burning megacalories just doing my daily chores (especially if I was one of the majority of Americans living on a farm and/or with little or no electricity or indoor plumbing):
Fetching water from a well or a nearby spring (using a handpump or having to carry bucket after bucket of water back and forth).
Running a coal or wood stove
Blacking the stove
Using a broom and carpet sweeper to clean the floors, and washing them on hands and knees (keep in mind that in the areas where there was a coal or wood stove, the floor and surrounding walls would be extremely grimy and filthy by today's standards...)
Doing laundry BY HAND or using a 'crank' washing machine (there weren't any dryers back then). Remember that most articles of clothing were very HEAVY - if you've ever seen dresses from that time, imagine how heavy they would be to lift them wet out of the wash water...and hang up to dry...then ironing with very heavy irons which had to be heated on the stove...
Baking bread from scratch (including kneading)
Beating eggwhites by hand
and so on...
So to partially make up for not having to do all that stuff, I exercise every day at the gym. I might be a sicko, but I really enjoy it and look forward to my workouts!
The essential thing is to start out with something you enjoy and can do, then go from there and challenge yourself. Mix it up a bit, you know?
Anyways...as usual I'm probably rambling here but it really comes down to 'practice makes perfect'. Sure it's tough starting a new eating plan and exercise regimen...but practice practice practice...make it SECOND nature and eventually you'll find you don't even need to think about it. Do I have something 'bad' once in awhile...sure! But it's just a matter of balancing out my eating for the rest of the day to make up for it along with probably one of THE most important elements of weight loss and maintenance - PORTION CONTROL...something that needs to be especially practiced. You're not always going to have a measuring cup or scales on hand (especially if you're in a restaurant or traveling or so on) so it's essential to learn how to eyeball your portions, so you know what a serving of chicken or rice or whatever REALLY looks like.
just my two cents for now!
