Weight Loss: Diet vs. Exercise
The two major players in the weight-loss battle are diet and exercise. But can the battle be won using only one of these tools? Many people opt for the easier route, which they believe is dieting. But when you consider how poor the statistics are for long-term weight loss through diets, you need to consider a combination of both. Normally, only about 5% of dieters are successful in keeping weight off, and weight cycling is very common. Usually one-third of weight lost is regained within one year and almost all is regained within three to five years.
How Weight Loss Works
The mechanism of weight loss is simple. It is encompassed in a concept called energy balance. When you burn more calories than you consume, you lose weight. Therefore, to lose weight you need to burn more calories and/or consume fewer calories. The combination of both of these methods is the best way to lose weight and improve your health.
How the Pros Do It
Members of the National Weight Control Registry are people who have lost weight and kept it off successfully for a minimum of one year. Of these people, 89% use a combination of diet and exercise, although 10% have had success using diet alone and 1% used exercise alone. However, research shows that the combination of exercise and diet is more effective than diet alone. Furthermore, while diet alone helps you lose weight, it is exercise that improves your physical fitness.
Getting Started
Combining diet and exercise can be tricky when you’re trying to cut calories. It is important to make sure that you eat enough so that you have energy to get through your workout, but not so much that you tilt your energy balance back to the weight-gain side.
While guidelines suggest 1 to 2 pounds of weight loss a week, you should set a goal that is both realistic and manageable for your lifestyle and fitness level. Overly aggressive goals often lead to attrition and failure.
Your diet should consist of low-fat food choices and a modest reduction in the total number of calories. Without overwhelming yourself with odd foods and food labels, try simply reduce your food portions by about 10 to 15%. Try to be consistent across the week, instead of dieting more strictly on certain days of the week.
With exercise and activity, people who successfully maintained weight loss exercised an average of an hour or more per day. Longer-duration exercise is usually needed to lose weight and prevent weight re-gain. However, this may be too much for you to begin with, so start small and gradually progress the duration of your activity by 10% each week. For example, increase the duration of your walks from 20 minutes during week one to 22 minutes the following week.
Staying Motivated
Changing your diet and exercise habits involves lifestyle modifications, but maintaining these lifestyle changes can be the real challenge. Many people can lose weight, but only a few can maintain that weight loss. Much of this is due to the fact that the lifestyle modifications made to lose weight need to be permanent. It is normal to regain a few pounds after your initial weight loss. The key is to not get discouraged and stay motivated. The smaller the amount of weight that you regain, the easier it is to lose again, permanently. So frequent monitoring of your weight is necessary to catch yourself when you start to regain weight. Keep in mind that the longer you keep weight off, the easier it becomes. For weight loss to be sustainable, it must be a slow process of 1 to 2 pounds of weight loss per week. Stay focused and goal-oriented and know that successful weight loss is possible!

Ten Fun Fitness Summer Activities for Kids
Summer is here and children need to stay active, healthy and busy during their break from school.Parents need to encourage their children to warm up properly and use dynamic stretches that mimic their sport activity. Parents should tell children never to play through any type of pain or make winning the reason for playing any sport. Let them choose the activity and keep the focus on having fun.
To keep kids moving, the American Council on Exercise suggests 10 fun fitness summer activities.1. Soccer—This highly active game involving both agility and teamwork has grown increasingly popular in the U.S. in recent years. To keep kids injury free, be sure they are geared up in appropriate protective equipment, such as shin guards. Soccer players should also wear shoes with cleats or ribbed soles to prevent slipping.
2. Martial arts—With a variety of forms to choose from, martial arts are a great way to get kids involved in a sport that incorporates strength, coordination and mental discipline. Proper training and equipment to prevent injury are a must.
3. Bike riding—Bicycle riding is a fun activity for the whole family. Experts suggest that children ride on sidewalks and paths until they are at least 10 years old, show good riding skills and are able to follow the rules of the road. Helmets, of course, are a necessity for both children and adults.
4. Swimming—Nothing beats splashing around a pool with friends, and swimming offers the benefits of a full-body workout for both young and old. The American Academy of Pediatrics recommends swimming lessons for children ages four and up, although classes are available for babies and toddlers as well.
5. Basketball—Whether it’s a round of HORSE, a game of one-on-one or a full-court competition, basketball is ideal for developing hand-eye coordination and teamwork. Encourage children under the age of seven to use a smaller foam or rubber ball, and lower the height of the basket if possible.
8. Board sports—Whether snowboarding in the winter, surfing in the summer or skateboarding year-round, kids love to be on the board. Injury risk, however, is higher for these sports. For both snowboarding and skateboarding, kids should wear helmets to prevent head injuries, and surfers or boogie-boarders should always be accompanied by an adult.
9. Jumping rope—Jumping rope is still a favorite on most playgrounds. Whether alone or in a group, jumping rope challenges both coordination and stamina.
10. Ice skating/inline skating—Ice skating, inline skating and hockey can be both fun and safe, as long as appropriate protective gear such as a helmet, wrist guards and knee pads are worn. Hockey players should wear a helmet with foam lining and a full facemask; a mouth guard; pads for shoulders, knees, elbows and shins; and gloves.

Weight Loss Plateaus and Pitfalls
It’s kind of like running into a wall—that feeling you get when, after a few months on a weight-loss program, you suddenly stop seeing results.
This is called hitting a plateau and it is not uncommon. In fact, unless you continually update your program to reflect the changes your body has already experienced, you can almost be guaranteed to plateau at some point along your journey toward reaching your goal weight.Weight-loss Woes
The first thing you should do upon hitting a plateau is try to determine the cause. Could you be eating more calories than you think? Research shows that most people under-report the number of calories they eat—it’s not that they’re lying; they just don’t know how to make an accurate assessment of how much they’re eating. And even if you’re eating fewer calories than before you lost the weight, you could be eating just enough to maintain your current weight at your current activity level.
Unfortunately, people’s bodies adjust their metabolism to resist weight change. This means that you burn fewer calories when you start consuming fewer calories. So, while a diet of 1,800 calories per day helped you lose a certain amount of weight, if you’ve hit a plateau, it could be that 1,800 calories is the exact amount you need to stay at your current weight.
Exercise Your Options
This leaves you with two options: Lower your caloric intake further or increase the amount of time you spend being physically active.
The first option is less desirable because you may not be able to get sufficient nutrients from a diet that is very low in calories (e.g., below 1,200 kcal in women and 1,500 kcal in men) and it is difficult to stick with it for very long. It is much better to moderately reduce calories to a level that you can sustain when you reach your goal weight.
The same is true for exercise. Trying to exercise for several hours per day to burn more calories is a good way to set yourself up for failure. Not only does this type of regimen require an enormous time commitment, it is hard on the body, making you more susceptible to injury and overuse syndromes.
Instead, aim for 30 minutes of moderate activity most of the days of the week and, as you become more fit, gradually increase the intensity and duration of your exercise sessions. Choose activities that you find enjoyable, whether that be in-line skating, step classes or even mall walking. The most effective exercise is the one you will do consistently.
Another means for getting you off the plateau is strength training, which has been shown to be very effective in helping people manage their weight because the added muscle helps to offset the metabolism-lowering effect of dieting and losing weight. Muscle is much more metabolically active than fat; therefore, the more muscle you can add, the higher your metabolism will be.
To help balance the intake with the expenditure, a good rule of thumb is to multiply your goal weight by 10 calories per pound, and add more calories according to how active you are. For example, if your goal weight is 145 pounds, then multiple it by 10 to reach 1,450 kcal as a baseline, adding calories as needed to account for increased activity. Check out the ACE Fit Fact titled “Calories Burners: Activities That Turn Up the Heat” to estimate the caloric demand of your workout. Again, be realistic. Don’t attempt too much in an effort to burn more calories.
Get Off the Plateau
If you’ve stopped losing weight, the key to getting off the plateau is to vary your program. The human body is an amazing piece of machinery, capable of adapting to just about any circumstance or stimulus. By shaking things up a bit and varying your program by introducing some new elements, you’ll likely find yourself off the plateau and back on the road to progress in no time.Additional Resources

Managing Cholesterol with Exercise
High cholesterol, known as hypercholesterolemia, is a major risk factor for cardiovascular disease. In the United States, more than 105 million people (that’s almost 50% of adults over age 20) suffer from elevated cholesterol. Individuals who are sedentary, overweight or obese, consume a diet high in saturated fat, have a family history of high cholesterol and/or are middle-aged or older are at particularly high risk of hypercholesterolemia and subsequent cardiovascular complications. The good news is that cholesterol levels can be improved with a little TLC; that is, therapeutic lifestyle changes.
Lifestyle Changes Are the First Step to Decreasing Cholesterol Levels
In fact, the National Cholesterol Education Program (NCEP) recommends that all individuals with an LDL cholesterol (low-density lipoprotein—this is the “bad” cholesterol) >100 mg/dL implement TLC to reduce cholesterol levels. Some of these individuals also will begin cholesterol-lowering medications if target LDL is not met after six weeks of the lifestyle changes. Refer to the accompanying table for NCEP cholesterol guidelines.TLC consists of heart-healthy nutritional choices, weight reduction and increased physical activity. Specifically, the TLC diet is low in saturated fat (<7% of total calories) and cholesterol (<200 mg). It contains up to 10% of total calories from polyunsaturated fats and up to 20% from monounsaturated fats. Together, the fat comprises 25 to 35% of total calories. Carbohydrates comprise 50 to 60% of total calories, and protein is 15% of total calories. Fiber recommendation is 20 to 30 grams per day. And importantly, the TLC diet emphasizes weight management or weight reduction when necessary through caloric balance such that calories in (from food) equals (or is less than) calories out (from exercise plus basic functions of living, such as energy required to digest food, etc.). This nutritional plan leads to decreased LDL cholesterol and increased HDL (high-density lipoprotein—the “good” cholesterol). Regular physical activity helps to increase HDL cholesterol, reduce VLDL (very-low density lipoproteins—a form of “bad” cholesterol), and in some cases decrease LDL cholesterol. Furthermore, physical activity reduces blood pressure, improves insulin sensitivity, and favorably influences cardiovascular function.
Improve Cholesterol With Exercise
When beginning an exercise program to improve your cholesterol levels:- Make an appointment with your physician to establish your overall cardiovascular health status. Your physician may want to perform more blood tests and/or a graded exercise test with an ECG (treadmill stress test) to determine your risk for cardiovascular disease.
- Aim to be physically active for at least 30 minutes on most, if not all, days of the week. Better yet, once you have integrated physical activity into your daily life, try to increase activity to at least one hour per day. Many research studies have shown that it is the duration of exercise—and not the intensity of exercise or the amount of improvement in fitness level—that is important for the improvement of cholesterol levels.
- Choose moderate-intensity exercises such as walking, swimming, walk-jogging or cycling. When exercising at a “moderate” intensity, you should break a sweat and feel slightly winded but still be able to talk. High-intensity exercise does not offer any increased benefit in improving cholesterol levels. Engage in weight-lifting or resistance-training exercises at least two days per week to maintain muscle mass. Adults ages 50+ who do not perform regular resistance-training exercises lose about 1/4 pound of muscle mass per year. Less muscle mass means decreased metabolism. And decreased metabolism leads to weight gain.

Alcohol Eats Away at Muscle Mass
If increasing muscle mass is one of your goals, then think twice before you go out for a night of heavy drinking. Consuming alcohol in large quantities has a direct effect on your metabolism, causing fat to be stored instead of being utilized as an energy source. Alcohol contains seven “empty” calories per gram, meaning that these calories don’t provide you with any of the essential nutrients you need to build that muscle mass you desire.
Effects of Excessive Alcohol Consumption on Your Body
- Muscles—Reduces blood flow to the muscles, causing weakness and deterioration
- Hormones—Reduces testosterone in your blood and increases conversion of testosterone to estrogen, causing increased fat depositing and fluid retention
- Liver—Creates imbalances that can cause hypoglycemia (low blood sugar), fatty liver and hyperlipidemia (build-up of fats in the bloodstream)
- Brain—Cuts off the supply of oxygen to the brain, resulting in a “blackout” caused by a lack of oxygen supply to the brain that can kill tens of thousands of brain cells
Effects of Excessive Alcohol Consumption on Physical Performance
Alcohol is a known depressant that suppresses the brain’s ability to function. Even though you may feel a “high” after several cocktails, the truth is that your reaction time, accuracy, balance, hand-eye coordination and endurance all decrease dramatically. Furthermore, the after-effects of a night of excessive drinking can be detrimental to your fitness goals. Alcohol is a diuretic that may result in dehydration. This dehydration is known to decrease physical performance, so that previous night of drinking will continue to affect you the following day.Alcohol and Sleep
Alcohol consumption can cause sleep disorders by disrupting the sequence and duration of sleep states and by altering total sleep time and the time required to fall asleep. It is popularly believed that a drink before bedtime can help a person fall asleep. However, alcohol’s affect on sleep patterns results in increased fatigue and physical stress to the body. Therefore, alcohol consumption indirectly affects a person’s strength-training ability due to increased fatigue and a lack of healthy reparative sleep.Alcohol and Nutrition
Alcohol inhibits the breakdown of nutrients into usable substances by decreasing the secretion of digestive enzymes from the pancreas. Regular alcohol consumption also impairs nutrient absorption by damaging the cells lining the stomach and intestines and disabling transport of some nutrients into the blood. In addition, nutritional deficiencies themselves may lead to further absorption problems. For example, folate deficiency alters the cells lining the small intestine, which in turn impairs the absorption of water and nutrients, including glucose, sodium and additional folate. Such interference of nutrient breakdown and absorption may impair the physical performance and recovery required to build and maintain muscle mass.Putting on the Pounds
Many people under the influence experience “drunk munchies” that can result in the consumption of several hundred extra calories for the day. A study examining how alcohol affects caloric intake found that subjects who drank wine with their lunch consumed an additional 200 calories and did not compensate for those calories by cutting back at dinner.Safe in Moderation
Now that you know some of the negative effects of excessive alcohol consumption, you might be scared to have that glass of wine with dinner. Don’t be. When alcohol is consumed in moderation (no more than one drink per day for women and no more than two drinks per day for men), it has been shown to have some positive effects:Increased HDL cholesterol (“good” cholesterol) within one to two weeks
Reduced stress levels
Reduced insulin sensitivity
The Take-home Message
In conclusion, if you want to increase muscle mass, decrease fat or improve general health, make sure alcohol is only consumed in moderation. Next time you are asked to go out socially, be the designated driver. Not only will your friends appreciate it and be much safer, but you will be one step closer to your fitness goals.Additional Resources
