If you are looking for a diet that will work for you, try your local library. There are so many diets out there these days that it is difficult to know what will work for you. Instead of spending your money on book after book that you can't use, head to the library and check out a variety of different diets. Once you find something that works for you, you can go ahead and purchase the books.
Weighing yourself regularly, but not too often, is a good way to monitor and encourage weight loss. Do a weight "check in" once a week. This helps you know where you are at, and allows you to set goals for the next week, month, etc. Weighing in more than this might be discouraging since weight can fluctuate a few pounds from day to day, even if you are sticking to your diet.
Losing weight is a personal journey that you have to go on alone. Follow the above tips to help navigate and guide you on that journey. Use the tips as a map to get to the weight goals you've set for yourself and don't give up. Keep going forward and you'll get where you want your weight to be.
