Welcome! You came to the right place, 3FC is GREAT for accountability.
I love to hear that you're ready to start again in a healthy way--! There are a lot of ladies here with a lot of different approaches, and some of them are bound to fit your weightloss style.
In terms of being "good" at weightloss... well. I think it's a struggle for everyone, or there wouldn't be super-populated online forums dedicated to people reaching out to each other for support. We're all in the same boat-- working long and hard towards a goal, and helping to keep each other in check! Definitely know you're not alone!
I'm not exactly a shining example of weight loss in my current state, but in the past I lost 40 lbs through strict calorie-counting. I ate 1200-1400 calories a day, and the weight melted off with very little exercise, or deference to the KIND of calories I was putting into my body.
Unfortunately, it wasn't sustainable. I wasn't able to eat 1200 calories for the rest of my life, and I wasn't able to avoid junk food for the rest of my life. Add to that that I'm an unfortunately black & white kinda girl when it comes to my eating habits, and I'm either "on" (eating obsessively healthily and feeling incredibly high and mighty when I turn down offered junk food), or "off" (Binging. And eating whatever my little heart desires).
This time around, (which only started a couple of weeks back) I'm working hard to put together a more sustainable plan. Exercise, no limitations, just checks and balances.
I'm taking hard-as-**** spin classes 2-4 times a week, going out of my way to add in extra walks, and am consistently trying to keep my eating balanced. I will eat something unhealthy for dinner, then balance it out the next morning with a healthy breakfast, a walk, and a healthy lunch. I'm adding in vegetables I don't normally like in an attempt to develop a taste for them and have been eating more lean meats and fresh fruit.
The weight is going, too. It's slow, but it's consistent, and I feel comfortable with the plan I'm using to make it happen!
Good luck to you (and you, Pyrrhic!), and remember-- only healthy approaches will keep weight off in the long-run!
