I think the reason that there are so many plans out there is because there are so many eating lifestyles that work for individuals.
You've done your research, you know what plans are out there, now you just need to fit the plan that works with the needs of your body.
How do you figure that out? I figured it out with an online calorie counter that tracks carbs/proteins/fats as well as exercise.
Contrary to what some people believe, calories are not just calories. What your calories are comprised of is just as important.
I looked at the weeks I lost and examined where my calories were coming from. No carb/no fat made me hold onto weight like a 6 year old with a fire truck on christmas morning. So add more carbs and fats... but the right kinds. Nuts, whole wheat bread, oatmeal, olive oil. It took some tinkering, a lot of tinkering. I do well with higher protein, too, but the types of proteins... beans and fish contribute to a loss more than chicken or steak. I thought about when I had energy and when I dragged around feeling hungry and how that affected my emotional health and my desire to be active.
You know your body, and if you don't, it's definitely time to get to know it. Once you are armed with that information, you can plug into one of these plans. Or not. It's ok to create your own plan... the Serval's Perfect Eating Lifestyle Plan (SPELP for short

).
