"How do I stay motivated?" seems to be a common question for those of us trying to lose weight. We start out with lots of enthusiasm, make some progress, and then slowly start slipping back into old patterns. I think that is the point where the vast majority of people give up, instead of really digging in for the long-term battle. I've done that before... you may have, too... but this time I am determined that things will be different!
Visualize what it will be like to reach your goal. Thinner, stronger, enjoying the things that you want to do but are presently difficult or impossible.
Put a photo of yourself at your heaviest weight where you can see it, along with pictures of people and activities that inspire you.
Reward yourself for accomplishments -- but not with food!
Make exercise part of your daily routine, even if only for 10 or 15 minutes.
Be realistic in setting goals -- but don't make them so easy that you feel you can let them slide.
Keep your goals in the front of your mind, ALL the time.
Look on being hungry as a good thing -- it means you aren't overeating.
Plan in advance what you will eat each day, and do your best to stick to it. Honestly and accurately keep track of everything you eat each day; stay within your allotted calorie range. Use your allotted calories for healthy and nutritious foods, not "junk." To paraphrase Jimmy Buffet, treat your body like a temple, not a tent!
If you can't remove all the snacks and goodies from your home (i.e., if you don't live alone), at least put them out of sight.
