No, they shouldn't be allowed on planes to begin with.

is moby dick a whale?

More or less, though to be honest I was not eating very healthy even when working out, I just burned a hell of a lot more than I took in.

Now I only eat when hungry and once I stop being hungry I stop, I don't wait until I get the "full" feeling.

See, I can't do that.  Luckily I just started watching what I ate, counted my calories, and lost like 30 pounds.

I just set a calorie budget, stopped drinking non-diet sodas, stopping eating fast food except every once and a while, and I was fine to eat until I was full.

An old boss of mine did something like this. As I recall, the rules were pretty simple:

1. As soon as you feel hungry, eat something. Don't wait until you're REALLY hungry.
2. As soon as you no longer feel hungry, stop eating. Do not keep going until you are 'full'.
3. Avoid fried foods when you can. It's not the end of the world to eat them once in a while, but avoid them when practical.
4. Avoid getting more than 1/3 of your calories from fat. Again, it's not the end of the world to do so once in a while, but avoid it when practical.

He called this 'grazing', because Rules 1 and 2 pretty much precluded the possibility of meals as we tend to think of them: it was more like a long series of snacks throughout the day. This makes it impractical for some school, job, or family scenarios. But he was in a situation where he could do it, and he dropped weight like a stone. Like an effing STONE, I tell you. Several of my co-workers tried it when they saw what it did for him, and it worked well for them too. Apparently this works by speeding up your metabolism.

Canned cherries were his favorite snack. Something about lots of energy in a small package.

Point #1 is a terrible idea.

The best thing you can do is just stick to a schedule.  Whatever that schedule whether it's the 6 meals a day thing or 3 meals and a snack just stick to it.  If you just eat whenever you're hungry you're going to mess with your metabolism and that's just never a good idea. 

It confuses your body so that it doesn't know when your next meal will be so it just starts storing food.  If your body knows when the next meal is, it knows how quickly to process food and energy.

If you're feeling hungry and it's not meal time yet just wait 15 minutes.  If you can't wait 15 minutes either drink a glass of water or chew a stick of gum.  Don't just eat because you're feeling hungry.

Oh, and I doubt he dropped weight like a stone because he followed all those rules, he lost so much weight because of point #3.  If a guy just stops drinking soda or going to fast food places he'll lose at least 10 pounds from that alone.

If people really want to lose weight, it's pretty simple:

1. Don't skip breakfast or any other meal.  Just make sure you don't skip breakfast.
2. Eat meals at regular times.
3. Set a calorie budget for the day and stick to it.
4. Stop drinking sodas (though having a diet soda a day is fine)

When I did that, the weight flew off and it was simple.  The calorie counting takes care of all that keep eating until you're not hungry nonsense *and* somewhat manages what you eat.  If you're trying to lose weight your budget doesn't allow for a lot of extra stuff.

When I did this my breakfast was generally a cup of cofee and a cereal bar which was 93 calories, lunch was usually a lean cuisine which ranged from 250-400 calories, and then dinner was generally about 1000 calories.  During the day I would have a 100-200 calories snack and I might have another in the evening if I had the calories left over.

I followed that and the weight just flew right off of me.
