Hitting The Dreaded Plateau
Every person who has ever tried to change their body through diet and exercise, and actually stuck with the program has hit the dreaded plateau. The plateau comes when the amount of changes you see or the weight that you lose begins to decline when compared with earlier measurements. This can cause motivation to decline as well, but there are other things that can help keep you motivated through this portion of the process.
Calorie Intake 
Think about what you did when you first started your weight loss routine. You dropped calories, cut out specific foods and drinks, and began using weight machines instead of the couch for relaxation time. All of those changes done at once or close together changed the way your body functioned. You probably dropped weight right away. However, your metabolism eventually became used to the situation and started slowing down to conserve the reduced number of calories it was getting. To get off the plateau, you just have to change things up again.
You don't necessarily have to change the amount of calories you consume, but you should probably take a look at the food you’re eating. You stopped drinking soda and your body responded, but now it may be time to stop with the cheeseburgers or change the kind of bread you eat with them.
Exercise Program
At first, exercising was hard. Now, you can do it faster, and with less effort. Try adding some new workouts or replacing ones that
aren't challenging you anymore. Any kind of activity is better than none, so your body dropped pounds once you sarted moving around more. Now, you can start targeting specific areas that you want to tone up. For example, maybe you used a rowing machine to work your arms and core. Now it's time to do some strength training on the legs with a leg press.
Just keep in mind that the plateau is only temporary. More than that. It's a sign that your body has responded and settled into a routine. The plateau is only a sign that you need to take what you have done and learned and hone that to be more specific.
