From my recent experience with the issue. Besides eating not just one but two pints of ice cream in the same day on a regular basis, but also finishing one but two bags of potatoe chips and sometimes even going for the cookie dough. thats at my worse which yeah, I need to come to terms and resolve that for myself soon.
So I think really what works and has been progressively working for me is.
One, know when your meal is over. Most people don't really have a proper established consideration that once they have eaten a proper meal, it is in fact time to wait till their next one rather than snacking through out the day to get their sugar and or carb rate.
Second would be. Learn to eat your proper portion that you set for yourself. If you have decided one or two bowls of your meal. Be able to accomplish it, and stay in that consistency in keeping your proper portions. Some people like me have to make sure that once we have eaten a decent generous bowl or even two, and say one dessert of some sort. Thats it. The meal is over. there is no more looking in the fridge.
So learn to moderate and eat proper portions of what can be considered a generous portion for one if you feel that is right for you. But more importantly begin learning to sustain and regulate saying no to excess.
I have to learn to eat only one or maximum two bowls of a meal, and so eat it with grace, appreciation, and a bit more slowly, because thats also why a lot of times we don't enjoy our meals.
that and know that desserts and sugar only taste good when its once in a while.
Theres also the major cut down of salt that when you do this for lets say a week. You go back to eating at a restaurant and most of the food you eat can be too salty.
