Fat Shaming, Witch Hunts, and White Knights
A long, but very worth your while read. And although harsh, it is the truth. The take away message is that in the end it all comes down to daily choices and priorities. What exactly you deem most important in your life is what you will do.
Being unhealthy is a choice. Carrying extra unhealthy fat is a choice. Everyday you decide what you eat and what you do. Every.single.day. You decide if you want to eat shitty food more than lose fat or be healthy. It really is as simple as that. It may be harder for some people to lose fat than others, but it is possible for everyone (there are a few medical exceptions to this, but very, very few).
I can assure you that if you are overweight or obese, you didn't get that way overnight. Therefore you won't get fit overnight either. That being said, you can make changes and be successful, but it will be hard and it will require sacrifice. The difference is just how bad you want it.
"There are people who've "tried everything" but the difference between those who don't succeed and those who do is persistence. Not everyone gets it right the first time."
Eventually you will succeed if you just stay the course.
I meet people all the time who tell me just this- they have "tried everything". Unfortunately when it doesn't "work" right away they give up and move on. Almost every diet plan on earth that results in a caloric deficit will work if you hang with it. Just because you aren't instantly lean doesn't mean it isn't working. You didn't get fat overnight- you won't get thin overnight either. It will require work from you. I learned long ago that I cannot intrinsically motivate people. You have all the tools already, you just have to decide how bad you want it. Unfortunately I can't do that part for you. That's up to you.
