There is no sense in repeating failed solutions. Unfortunately in trying to lose weight, the tendency is to rely on just what didn't work in the past. Another food plan. Another diet. Another weight loss failure.
Previously unsuccessful attempts mean that you have to be more creative. Don't even try to put a square peg in a round hole again.
Use your creativity to ask yourself some essential questions.
Am I ready to get on a food plan right now? Do I have the skills it takes to work my food plan and stay on it? Do I have the emotional wherewithal to diet? Do I have the right social support? Can I monitor myself well enough? Can I prevent myself from jumping to premature conclusions? Can I adjust my thinking and my efforts to fit what I'm discovering about myself as I diet?
Then, be guided by your answers and formulate the best plan for weight loss that you can. The creativity is in making a plan that really fits you.
