Article: As you begin playing ping pong, record when each player scores a point. Essentially, you score a point by keeping the ball in play longer than your opponent.  If your opponent fails to hit a ping pong ball that you served or hit last, you get one point for the game.  Remember, in ping pong you have to hit your ball so it bounces off your end of the table, and then off your opponent's end of the table. If your opponent misses the ball, but the ball does not bounce on his or her side of the table, you do not get a point. You can also lose points in ping pong. Make sure to record when you lose a point. Under the following conditions, you would subtract one point from your total score.  If you miss the ball, you'll lose a point. If you hit the ball into the net and it falls back onto your side of the table, you'll lose a point. If you hit the ball too hard, and it falls off the table, you lose a point. You cannot hit the ball before it bounces off of your side of the table. If you do so, you'll lose a point. If your ball bounces twice on your side of the table, you'll lose a point. If you accidentally move the table during play, you'll lose a point. Each time you or your opponent misses the ball, you will have to serve the ball again. In ping pong, service changes every two points.  For example, you serve the ball to begin a game. You score one point, after your opponent fails to hit the ball. It would be your responsibility to serve again. Then, your opponent scores a point on you. Once again, you serve the ball. You have reached two total points in the game, one for you and one for your opponent. The next time a point is scored, it's your opponent's turn to serve. He or she will keep serving until another two points are scored. Then, it's your turn again.

To determine what your healthy goal weight should be, use the body mass index (BMI), which can be used to predict risk for chronic diseases. BMI is a person's weight in kilograms (kg) divided by the square of the person's height in meters (m). Identify the weight you would like to be in kilograms and then divide that by your height in meters to see if it is healthy. You can also use a BMI calculator, such as the one on the NIH’s website: https://www.nhlbi.nih.gov/health/educational/lose_wt/BMI/bmicalc.htm Increase or decrease that goal weight so that it fits within the BMI range considered healthy:  A BMI below 18.5 is considered underweight. A BMI of 18.5-24.9 is a normal or healthy weight. A BMI of 25-29.9 is considered overweight, while a BMI greater than 30 is considered obese. Along with finding a healthy weight, also realize what is realistic. If you are 100 lb away from your healthy body weight with only a month before summer, consider setting a smaller, more attainable goal. The more calories you cut back, the more weight you will lose; however, it is important that you do not eat less than your Basal Metabolic Rate, the amount of calories your body needs to function effectively when at rest. This number can be calculated using an online BMR calculator. In general, don't aim to lose more than one to two pounds per week. A loss of one to two pounds per week is a healthy rate at which to lose weight; any more than this could be too drastic a change and may signify that your body is not getting what it needs. To do this, try to eat 250 fewer calories per day and burn an extra 250 calories a day. This ratio will create enough of a calorie deficit that you should lose one pound per week. During the summertime, you are surrounded by opportunities to eat, whether it’s at a barbecue, pool party, ice cream party, or summer luau. However, if you want to lose weight over the summer, it's important that you cut back on the number of calories you eat. As a general rule, weight loss occurs when you burn more calories than you consume.  To help figure out how many calories you normally eat each day, track your food for a day by writing down the number of calories in everything you eat and drink. Calories are listed on the back of food labels. For foods that do not have labels, you can find information about the caloric value of certain foods online through the USDA Food Database.  Pay attention to the number of servings you eat and multiply this by the number of calories per serving. For example, if you ate 30 chips and a serving size is 15 chips, you need to multiply the number of calories by two since you ate two servings. Once you have figured out how many calories you normally eat, cut down this number by 500-1000 calories per day to lose weight. In this log, record what you eat and the type and duration of exercise you're doing every day. This is a simple yet very powerful tool to keep yourself accountable. The log will help you track your progress and see whether you are keeping to your healthy diet and exercise regimen.  This is a wonderful way to hold yourself accountable and stay on track. There are many apps for smart phones that have capabilities to track food intake, energy expenditure, water intake and more! Often, we tend to overlook the snacking we do between meals and instead think our diet is not working. Studies have shown that most people underestimate how much they eat by 25 percent.  In addition, many of us think we get more exercise and burn more calories than we do. Use the log to identify how many calories your exercise—whether it be a run on the treadmill or a spin on the bike—is burning. If you use cardio machines at a gym, the number of calories is usually digitally calculated and displayed. Make sure to put in your particulars, such as weight and age, to achieve an accurate count. There are also online charts that can help tell you how many calories a half hour or an hour of a given exercise burns. You might also discover useful information about your daily habits and a reality check about how many calories you actually consume and burn off through exercise. Once you know your habits and patterns better, you can begin to address problem behaviors that are hindering your progress. Find a partner—whether that be a spouse, friend, or family member—who wants to join you during outdoor activities, hit the gym with you, or join your healthy eating plan. Having social support will make it easier to lose weight because the other person will also keep you accountable and be a sounding board for any obstacles and struggles you face along the way. If you cannot find a friend or partner to help you with your weight loss journey, utilizing the services of a personal trainer or registered dietitian will keep you accountable and help you stay active and eat healthy. A trainer can also be a huge support system. Think outside of the box for your support system! Always consult your physician before beginning any type of weight loss and/or exercise program. You should also consult your physician throughout your weight loss program and keep him updated of any changes or symptoms you may be experiencing, such as constipation thanks to your new diet plan or lethargy due to not getting enough food. In addition, you should also talk to your doctor if you are eating well, tracking your calories and watching what you eat, exercising, and are still not losing weight. This could be indicative of a more serious underlying medical condition, such as a thyroid problem.
