Welcome to Spark People !! I'm going to give you one piece of advice I give to all new members and it's this,"Don't look at good health or weight loss with an all or nothing mentality". If the only healthy thing you did for yourself was drink 8 glasses of water, that's still a step in the right direction.
Start with some simple changes first so that you don't feel overwhelmed. Example, if you're not eating 6-9 servings of fresh fruit and veggies, set a goal to eat 2-3 servings each day for one week. If you're drinking 8 glasses of water, set a goal to drink 2-4 glasses each day for one week. If you're not exercising, don't try to do an hour a day, set a goal to take a 30 minute walk each day for one week. Once you've achieved these goals, then you set new ones.
And that's how good health starts. It's not "all or nothing". It starts with a few simple changes because one small change CAN change your life !
You are not too old to make a difference or a change, you have to believe that. But, you have to be practical too. This isn't the Biggest Loser. Those types of weekly losses are just not typical. While a safe weekly weight loss would be 1-2 pounds per week, there will be weeks you don't lose. There may even be weeks you gain ! And that doesn't mean you're doing anything wrong.
You have to start slowly. Take baby steps literally and figuratively. If you feel stressed out and don't know what to do, post on the forums. The Spark Community will support you.
But you have to be ready to do things that might take you out of your comfort zone. You might have to get up early in the morning to take a walk. You might have to spend more time in the grocery store making better selections. It's going to be a lot of work, but you have to tell yourself that you ARE worth all the effort !!
There is a lot to learn. That's why you need to start slowly. Start here. www.sparkpeople.com/resource/motivation_ar
