I do this when I want to lose weight. It?s very simple and might work for you.
1). Make a chart, date across the bottom weight on the vertical. Draw a line on the chart starting with your current weight and dropping 1 lb per week.
2). Every morning weigh yourself and put a dot on the chart.
3). If the dot is above the line, only fruits and vegetables for you that day. If the dot is below the line, eat and do whatever you want.
