If you want a more accurate number, you will have to first calculate yourlean body mass, and then choose the body fat percentage that you want to reach in your weight loss program.
The process is explained in my weight loss tracker section. This is where you can read about the process of accurately calculating your ideal weight.
Once you calculate your ideal weight, the best way to create it, is by designing your own weekly weight loss chart, and then taking action toward your goal.
While moving toward creating your ideal weight, in the section on interpreting your weekly weight loss chart, you will find different steps that you can take to adjust your approach during your weight loss program.
This entire site is built around the idea that by using a moderate approach in your daily nutrition habits and in your exercise program, you can create the body of your dreams.
