Dinner starving causing Yo-yo effect

    

      Obesity is increasing much death rate today. It kills many people by many severe diseases such as diabetes, high blood pressure, heart attack etc. There is high percentage overweight people and some are in the weight loss program. They lose their weight by the different ways such as eating low fat more protein, exercise. Some diet course have to pay for its programs. Certainly there are the wrong ways to lose weight and I focus on the dinner starving method. By this, people who try to lose weight only eat breakfast and lunch in a day. They don’t eat dinner because they believe that the dinner is the last meal of the day. They have no many activities after the last meal so the energy will not be used. Then the energy from dinner will store in form of fat and make them fat.

    "Yo-yo dieting or yo-yo effect, also known as weight cycling, is a term coined by Kelly D. Brownell at Yale University, in reference to the cyclical loss and gain of weight, resembling the up-down motion of a yo-yo. In this process, the dieter is initially successful in the pursuit of weight loss but is unsuccessful in maintaining the loss long-term and begins to gain the weight back. The dieter then seeks to lose the regained weight, and the cycle begins again."[1] I will prove this theory by myself by the following methods.

Methods

• Participant, age 17 person with moderately active activity (exercise 3-5 times per week)
• Starving dinner for 7 days
• Observe weight and record the results day by day (before bed time) 
• Back to eat dinner in the next week and observe the results
