Obese because of my DAD!

I think it is awesome that you are making this change in your life, but I think there's only so much you can blame on others, and I'm talking from my own experience.
It might be true to some point when you are just a kid, but when you are all grown up, you have to take charge. It's not like they are force feeding us cupcakes are they?
And believe me, it is a big relief when you take the power away from others. My bro used to eat pizzas, burgers, ice cream, you name it in front of me all the time - that's how I learned to exercise my WILLPOWER. Just focus on your goal. For example, I asked myself, "Is eating pizza is going to help me get there? No way!!"
Keep you eyes on the price

Holding a grudge is like eating poison and expecting the other person to die.

If you keep blaming your dad, you will do yourself a disservice by not owning all the accountability, imo. Our parents definitely influence our actions in ways we don't even realize, but we shouldn't just be out to prove them wrong. That takes all the fun out of it.

When I was growing up (i'm the same age i will be a high school senior this year), my family was never health-conscious when it came to food. I'd eat fast food all day, or at home have high calorie frozen meals or zebra cakes donuts etc. No one taught me to eat well or encouraged me to eat the right things because they were eating the same things as well. Of course, as I grew older and dealt with emotional changes, I began indulging more in these foods. My weight has always been up and down, but now it is at its highest. My dad still continues to eat fast food/high caloric processed foods for every meal, but now my mom eats healthy (all vegetables, turkey/chicken, and fruits) and she dropped from 170 to 112. She inspires me, but the decisions I make are still on my terms and even though my eating environment is different and my fridge is healthy at home, when I go out I have made mistakes where I didn't use any willpower. Lately that hasn't happened though! You can do this though, for yourself of course but it will also be nice as you're reaching your goals you'll be proving your dad wrong as well because you are strong enough to make a change!

I'm sorry to hear that your dad has NOT been helpful as far as your health and fitness goes....I too had someone in my life that was always negative towards my weight and eating! it was my stepdad (at the time) and he would always call me fat and lazy... but after I became an adult...and had lost over 100lbs I talked to him about it....and although I can't change the past, I did get an apology and a little closure along with it!

once you get to your goal...I would recommend that you have a serious talk with your dad about how negative he has been towards your health...you will feel a ton better afterwards

My mum first put me on a diet when I was 6 . They continued from there , my weight went up n down like a yo yo .my child hood was pretty crazy and I emotionaly ate through it . I hit my highest weight of 150 when I was 16. =(. I decided I had to loose it , so I did. And I to use to blame my parents , my mum especialy . But as I got older , IV now have a kid of my own , I realise that our parents do ,say ,feed ,treat there children the best way they now how. And there is a point where you have to forgive all the hurt they have caused and take resonaibilty for your own life , and create it the way you want it. Because if you don't deal with the emotional side of your weight problem then you will never truely be free. Buy the book women food and god. It helped me alot

Has anyone else have problems with parents and their weight?

A thousand times yes, but with my mom more than my dad. I was always a chubby kid, and my weight yo-yoed quite a bit all throughout my adolescence. I ended up developing some eating disorder issues and struggled with bulimia in high school because of my anxious personality and my mother making me a nervous wreck. When I got to college, I lost 65 pounds in the first 6 months of my freshman year, basically by not eating (seriously, there were times I only ate on weekends). I came home at Thanksgiving with 35 pounds off and my mother said, "Great start!!"

Needless to say, I've gained all of that weight back and more - I managed to keep it off for a few years, but it's back now, plus a few pounds.

The reasons I share this are twofold: 1) If you feel like you have anything close to an eating disorder (this includes compulsive overeating), talking to someone can really help, and 2) I had some heartfelt discussions in the last couple of years with my mom, and it has really helped her (and me) to be less judgmental and more encouraging.

Best of luck on your weight loss journey and in getting things figured out with your dad. You can do it!! And this community is awesomely supportive

You say you're not holding a grudge but then you say you'll forgive him one day, just not now... so which is it?

You're young and I realize that today's society likes to play the blame game. You aren't being force fed or chained to a couch so you cannot exercise... so there needs to be some personal responsibility.

I have worked with students that come from abusive households... it isn't acceptable for them to turn into abusers themselves and say "my parents made me do it." Personal responsibility has to come into play and myself, like countless others here, have dealt with the cards we were handed but chose a healthier and more productive path. Live in the past or move forward and I hope you choose the latter. Best of luck.
