When I grew up I was in an abusive home. They told me all my adult life I only got spankings that I deserved. I swore I would be a different type of parent.
So when my daughter was born I didn't discipline her at all. I let her do whatever because any time I got frustrated with how she was acting I remembered what it was like growing up and getting the hell beat out of me with belts, switches, and any utensil that my mom was cooking with.
So by swearing I was going to do opposite of what my parents did to me I hurt my daughter and myself. Now I do give swats to my grand kids that I am raising and have given swats to a few good friends kids with their approval but that is for serious offenses.
One thing I always point out to people here on mamapedia is that if you deny your kids (or yourself) stuff then they are going to want it all the time when they are an adult.
I didn't get much candy as a child so when I grew up and was a full time college student I ate a candy bar 3 times per day and stayed busy. I never stopped to cook or eat a full meal. I was so skinny that I thought life was good.
So depriving people of something isn't the way to go nor is stuffing them with something all the time too.
So I suggest that you check out some cookbooks at your local library that has recipes with foods that your family likes to eat, that you can incorporate into your menu. SO that YOU can have a healthier diet but also have indulgence foods once in a while. You can have a slender piece of cake, a spender piece of pie, etc....you don't have to eat cake for 3 meals per day.
Your mom has decided she's an adult and has the ability to choose her lifestyle. It is CERTAINLY NOT something I would eat for 3 meals nowadays. I know better for my own body.
I think that you have "some" good ideas but truthfully it sounds like you're on the edge of a serious eating disorder like Anorexia or Bulimia since you sound like you think that food in general is harming you.
It might help to visit with a good friend about this, one that will tell you if you are fat or if you're just slightly plump or a normal body weight that is acceptable. I think that a friend would care enough about you to tell you if they think your food choices are good, okay, or really strict. Sometimes it's that over correction, restriction, that makes it all too hard.
One thing that I do now, instead of eating 3 candy bars per day for meals, is to freeze some candy like Jr. Mints. When I want something sweet I grab a small handful (5-8) and eat them 1-2 at a time. They are super chewy so they last a long time and I get the impression I ate a LOT more of them.
Keep normal sugared gum on hand. Chewing indicates to the stomach that food is coming to it empties and that signals the digestive system to do it's job. That gets your system going. I chew gum when I have an urge to eat and eat and eat. It keeps my mouth busy, tastes good, is sweet, and it doesn't hurt anything.
When my sister quite smoking she gained about 30 pounds. She's just under 5' tall and her normal weight is just over 100 pounds. So when she weighed in at 130+ she couldn't stand to be in her own skin. So she started sucking on hard candy, spearmint/peppermints, all sorts of hard candy in different flavors. She could have a piece of candy in her mouth all day and never go over 100 calories. If you don't chew it then you'll have that flavor for a long time.
