Yo-Yo Weight Gain and Weight Loss is a condition where a person will impose strict diet plans and then successfully loses some weight but is unable to sustain that weight loss for any extended period.

Once normal eating habits are resumed and the weight previously lost is regained, the cycle of yo-yo dieting begins again. And just like a pendulum that swings back and forth, the cycle never ends.

Adding another dimension to this situation is that after many cycles and the loss of muscle mass it becomes increasingly more difficult to even accomplish the slightest weight loss. The solution is a change in lifestyle, a change in eating habits that can be successfully maintained – together with some regular physical activities.
