Scared.....

Take you time and loose slowly set small goals and not the full goal at once. And just ty and enjoy it because if you enjoy it you will continue on the journey. I am 53 and had around 30 Kg to much weight sofar i have lost half of it in around 3 months. But have also starting to feel fitter and more healthy even if i eat fast food when in a hurry just smaller portion and not so oft. It is all Cal in and Cal out. Sure the nutrions are important but at a first stage loose the weight then start looking harder on the small stuff.
Good luck and feel free to add me as friend

You can do it! Don't look at it like "100 pounds". Here is an example of a few ways that are more manageable:
- 10 pounds to reach my next milestone
- 20 more pounds and I will be the weight I was when I went to [...] and had a good time
- 10 more minutes and I will be able to brisk walk a full 30 minutes
- 3 low calorie foods I've never tried to reach my goal for new foods to try this month
- 1000 more steps to beat my previous record
- 2 more pounds to lose the weight of my cat
- .... etc

Even if you stumble along the way, there is always a tomorrow and it doesn't undo all the work you've done. Failure is scary, but did you know you are already a winner by losing the weight once before? Obese and overweight people who manage to lose at least 10% of their starting weight are better off when it comes to future health issues, even if they regain it. So you've already done yourself good, now it's time to attempt to do good once more.

If you look at how much you have to lose that can be pretty daunting. Set yourself small goals. Make small changes that you know you can stick to. If you go in full tilt you can find it too much and give up. Setting small goals and reaching them can be hugely rewarding and keep your motivation high. You did the right thing joining this site.

Well starving is not a great strategy. Just cut your calories as much as you need to lose weight but eat enough to avoid hunger. This way over the long term makes it easier to sustain without binges and falling off the wagon. Its good to avoid hunger. So i recommend keeping your meals close together. Three meals with snacks to fill in any long gaps between meals but preferably nothing after dinner works well for me. You should not leave the table feeling hungry but you don't want to feel full either. Just eat to satiety. And eat healthy food. make sure you enjoy the food you eat otherwise you may not reach your goal. If you enjoy the process, there's not much that can ruin your efforts.
