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.
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.
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.
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.

Interval Training
Lack of time is the number one reason people give for not exercising. And lack of results once they do start exercising isn’t far behind. Interval training is a great solution for both of these common problems.
Interval training involves alternating short bursts of intense activity with what is called active recovery, which is typically a less-intense form of the original activity.
The Swedes came up with a term for this type of training: Fartlek, which means speed play. Not only is it an efficient training method, Fartlek training can help you avoid injuries that often accompany non-stop, repetitive activity, and provides the opportunity to increase your intensity without burning yourself out in a matter of minutes.
Unlike traditional interval training, Fartlek training does not involve specifically or accurately measured intervals. Instead, intervals are based on the needs and perceptions of the participant. In other words, how you feel determines the length and speed of each interval.
Interval training utilizes the body’s two energy-producing systems: the aerobic and the anaerobic. The aerobic system is the one that allows you to walk or run for several miles and uses oxygen to convert carbohydrates from various sources throughout the body into energy.
The anaerobic system, on the other hand, draws energy from carbohydrates stored in the muscles (in the form of glycogen) for short bursts of activity such as sprinting, jumping or lifting heavy objects. This system does not require oxygen, nor does it provide enough energy for more than the briefest of activities. And its by-product, lactic acid, is responsible for that achy, burning sensation in your muscles that you feel after running up several flights of stairs, for example.
Interval training allows you to enjoy the benefits of anaerobic activities without having to endure those burning muscles. In its most basic form, interval or Fartlek training might involve walking for two minutes, running for two, and alternating this pattern throughout the duration of a workout.
The intensity (or lack thereof) of each interval is up to how you feel and what you are trying to achieve. The same is true for the length of each interval. For example, if it is your habit to walk two miles per day in 30 minutes, you can easily increase the intensity of your walk (as well as up its calorie-burning potential) by picking up the pace every few minutes and then returning to your usual speed.
A great trick is to tell yourself that you’ll run a particular distance, from the blue car to the green house on the corner, for example, and then walk from the green house to the next telephone pole.
When you first start Fartlek training, each interval can be a negotiation with yourself depending on how strong or energetic you happen to feel during that particular workout. This helps to break up the boredom and drudgery that often comes from doing the same thing day after day.
Despite its simplicity, it also is possible to take a very scientific approach to interval training, timing both the work and recovery intervals according to specific goals. Keep the four variables listed in the box to the left in mind when designing an interval-training program.

Exercise to Boost Your Job Performance
How would you like to feel more energized at work — to sharpen your brain and enhance your ability to concentrate, learn, and think creatively? Not only would you feel better physically, but you’d be more motivated — and at the top of your game, career-wise. Sound good?
Exciting new research shows the remarkable effect of moderate-to-vigorous exercise on brain structure and function. A brisk walk during a morning break or a cardio class at lunchtime balances neurotransmitters and other chemicals in the brain — substances responsible for influencing brain activity related to mood, attention, learning, motivation, and arousal. That’s why you’re likely to feel calmer, yet more alert — and better able to focus — after exercise.
Exercise also helps the brain — and body — cope better with stress. That’s good news for people who work in high-pressure environments.
According to author and Harvard psychiatry professor Dr. John Ratey, another influence on the way the brain works is brain-derived neurotrophic factor, or BDNF. This substance boosts brain cell (neuron) growth and strengthens cell-to-cell connections, essentially changing brain structure. It even protects neurons against age-related changes that can lead to cell death and dementia.
Stronger, healthier, better-connected, bigger brain cells equals increased learning capacity. And here’s the big discovery — exercise floods the brain with BDNF, providing the infrastructure it needs to absorb information, process, remember, and use it.
Ratey points out that even though exercise boosts BDNF, more is needed to optimize brain function. Ideally, exercise should be paired with or precede complex motor or cognitive tasks — to build neurons and give them something to do. So activities like figure skating, rock-climbing, or soccer fit the bill — as do running, brisk walking, or swimming followed by reviewing data reports, participating in a Web conference, or repairing a vehicle. The key is to keep finding ways to challenge your body and your brain.
Trying to learn difficult material while on the stair climber is futile — because blood flow shifts away from the part of the brain responsible for critical thinking. But when you’re done working out, brain blood flow — enriched with higher levels of BDNF — returns to normal. According to Ratey, this is the optimal time for focusing on tasks that require serious brain power.
Many modern workplaces are increasingly sedentary, increasing worker risk of inactivity-related injuries and illness. While excessive sitting has been shown to impart risks that are independent of exercise level, an active lifestyle clearly cuts down on sitting time and results in both physical and mental benefits:
One study showed that a supervised, pre-planting season exercise program among reforestation workers reduced injury rates from 22% to less than 5% — and increased productivity.
A daily supervised 10-minute stretching program among assembly-line workers showed significant improvement in joint flexibility, fatigue, anger, depression, and overall mood.
A nine--month study of 80 executives showed that exercisers experienced a 22% increase in fitness and a 70% improvement in ability to make complex decisions compared to sedentary peers.
A study of railroad workers showed that 75% of employees reported improvement in on-the-job concentration and overall productivity.
In addition to increasing the ability to focus, think clearly, and learn more effectively, regular exercise improves mood, relieves anxiety and depression, enhances energy, and promotes self-efficacy. When you feel great and believe in yourself, your mindset at work is bound to be optimistic, and that bodes well for job performance — and career growth. When you stay physically active, you’re taking care of your body and your brain — reducing health risks and increasing your capacity for learning, motivation, and sharp thinking.
The nature of work in today’s marketplace often involves juggling multiple roles, heavy workloads, and the ability to think on one’s feet. Athletes train for peak performance — and research points to plenty of good reasons for workers in other fields to follow suit.
