I think we all experience self doubts like this. For many of us, being overweight was a shield (protective barrier) against the outside world. It's a barrier that keeps people away. And that's the problem. When we put up barriers like that, it does isolate us from everyone else. How many of us felt lonely when we were overweight ?
I know it's going to be hard, it was hard for me. But you have to be brave and come out of your comfort zone. Don't worry about the "what ifs". If you worry about the what ifs, life is going to pass you by.
Will men notice you once you've lost weight ? Yes, you will get more attention. Some of it will be good and some of it will be less so. However, you can't worry about that. As the old song goes,"accentuate the positive and eliminate the negative". Think about all the POSITIVE things that will happen as you lose weight.
You're going to feel less joint pain. You're going to have more energy. You're going to have a stronger immune system. You're going to decrease your risk for heart disease, diabetes, osteoporosis and maybe even cancer. You're going to live a longer more productive life.
As I tell all new members,"Don't look at good health or weight loss with an all or nothing mentality". If the only healthy thing you did for yourself today was drink 8 glasses of water, that's still a step in the right direction. So, don't worry about that pint of ice cream, put it behind you. Eating it doesn't make you a bad person or an unhealthy one. Even ice cream can be a part of a healthy lifestyle.
