Body for Life is a popular 12-week diet and exercise program. It was created by Bill Phillips, a former competitive bodybuilding and the founder of EAS, a manufacturer of nutritional supplements. It has been popularised by a bestselling book of the same name. The first annual Body for Life competition was held in 1997.
None of the principles behind Body for Life are original or unique to it. Body for Life makes use of principles that have been widely known in bodybuilding circles for many years. Its innovation lies in the way it has been packaged and marketing. It is the first such program to attract widespread interest from ordinary individuals since Angelo Siciliano. It has inspired numerous imitations, and supports an extensive ancillary industry of gyms, nutritionists and personal trainers.
"It?s hard not to like the way Phillips guides a dieter through the difficult process of shaping up. He commiserates over potential fitness and weight-loss pitfalls like a good buddy might. And he?s extremely adept at delivering lingo that is motivational. But with an everyday exercise regimen and a rigid diet plan, you?re likely to be in for some major work with this plan."–Maureen Callahan (Health Magazine)
The Body for Life diet consists of six meals a day, each of which consists of a portion of a lean protein-rich food, a portion of an unrefined carbohydrate-rich food and a portion of a vegetable. The vegetable is included for its dietary fiber and vitamin content, and to help bulk out the meal. A portion should be approximately the same size as the person's hand, either open or clenched into a fist. The meals should be spaced about every three hours.
The diet should be supplemented with a tablespoon per day of safflower, flaxseed, sesame or canola vegetable oil, perhaps in a salad dressing, to provide necessary Omega-3 fatty acid and Omega-6 fatty acid essential fatty acids. A popular alternative is a small handful of walnuts or almonds. At least 10 cups of water should be drunk throughout the day.
One day a week, typically Sunday, is considered a "free day," on which any foods can be eaten. This is considered an important "breathing space," both psychology and physically.
At several points in the book, Phillips unsubtly promotes EAS nutritional supplements. This attitude has attracted widespread criticism. The program does not rely on EAS products: in fact, any brand can be used. It is also possible to follow the program without taking any nutritional supplements.
The diet program relies on three key principles:
This is considered crucial. Its benefits include:
One reason that diets can fail is that weighing food and counting calories can become just too much of a hassle. Estimating portion sizes by comparing them to the size of your hand is quite simple, potentially reducing mistakes and making it harder to cheat. The diet also adjusts naturally to the size of a person's frame, without the need for complex calculations.
Carbohydrates provide the main energy source for the body, but three to four hours after eating there is little glucose left in the bloodstream, which can lead to symptoms of hypoglycaemia, including a slowing down of the body's metabolism. Frequent but small meals prevent this from happening, and also increase the metabolism slightly by keeping the body geared towards digestion. The overall insulin challenge is reduced, thereby reducing the risk of reactive hypoglycaemia and the risk of triggering diabetes mellitus.
The human body adapts itself to changes in nutritional intake. If the calorie intake is reduced, the body responds by slowing down its metabolism, and by catabolism muscle in preference to fat. This reduces the metabolism long-term. When the diet comes to an end and normal calorie intake is restored, the individual starts to gain weight even faster than before. This is known as yo-yo dieting. Diets that focus exclusively on calorie reduction often fail in this way.
With these concerns in mind, Body for Life addresses energy expenditure (i.e. exercise) in addition to energy input. For best results, Body for Life holds that this exercise should include weight training to build skeletal muscle and increase the metabolism over the long term. This also helps to maximise the energy expenditure and Adipose tissue loss from aerobic exercise.
Body for Life's exercise program is more complicated than its diet program. It suggests exercising six days a week, normally Monday to Saturday, and alternating between weight training and aerobic exercise. The seventh day, usually Sunday, is a rest day. Weight training sessions alternate between exercises for the upper body and exercises for the lower body. This allows the exercised muscles enough time to recover fully before the next training session.
Each fortnight follows the same pattern:
Monday | Tuesday | Wednesday | Thursday | Friday | Saturday | Sunday | |
Week 1 | Upper-body Weight Training |
Aerobic Exercise |
Lower-body Weight Training |
Aerobic Exercise |
Upper-body Weight Training |
Aerobic Exercise |
Rest |
Week 2 | Lower-body Weight Training |
Aerobic Exercise |
Upper-body Weight Training |
Aerobic Exercise |
Lower-body Weight Training |
Aerobic Exercise |
Rest |
Body for Life uses Gunnar Borg's Rating of Perceived Exertion for assessing the intensity of exercise based on how hard you feel you are working. It uses the variant developed by the American College of Sports Medicine, which uses a scale of 0 to 10:
These levels accommodate differences in Physical fitness. An unfit individual may require a level 10 effort to walk briskly uphill, whereas for a competitive Athletics this may only be a level 3 effort. Over the course of the 12-week Body for Life program an individual would get noticeably fitter, so their intensity scale needs to be adjusted over time. This is considered normal.
Body for Life uses a "wave" pattern, periodically building up from level 5 to level 9 or 10 during an exercise session. This allows the mucles to warm up, and gives the body a chance to build up to a "high point" of maximal exertion. Brief but intense exercise provides maximum stimulus for the body to build strength and endurance, but without the risk of overtraining.
Exercises for upper-body muscle groups include:
Exercises for lower-body muscle groups include:
Most of these exercise can be performed using either dumbbells, a barbell, a Smith machine, a cable machine with adjustable pulleys or a specially-designed apparatus. Two exercises should be chosen for each muscle group. Five sets of the first exercise are performed, and then one set of the second. Weights for each set should be chosen so that the specified number of repetitions can be achieved at the specified level of intensity. For example:
Chosen Exercise |
Chosen Weight |
Specified Repetitions |
Specified Intensity |
|
Set 1 | Leg Press | 100 kg | 12 | 5 |
Set 2 | Leg Press | 120 kg | 10 | 6 |
Set 3 | Leg Press | 140 kg | 8 | 7 |
Set 4 | Leg Press | 160 kg | 6 | 8 |
Set 5 | Leg Press | 140 kg | 12 | 9 |
Set 6 | Leg Extension | 50 kg | 12 | 10 |
Weight training sessions proceed at a brisk pace, with one minute of rest between the first four sets for a muscle group, and no rest between the final two sets. The cadence for each repetition should be one second to lift the weight (while Breath deeply), one second holding it at the top, two seconds to lower the weight (while inhaling deeply) and then one second pausing before the next repetition. Each session should be completed within about 45 minutes.
Most forms of aerobic exercise are suitable. Common choices include walking or running (perhaps on a treadmill), cycling, swimming, or the use of a rowing machine or cross-trainer. However, exercise classes are generally not suitable, unless they are specifically designed to suit Body for Life.
Aerobic exercise sessions are limited to 20 minutes duration. They compensate for this by following the same "wave" pattern of steadily increasing intensity as the weight training sessions. During the first five-minute period the intensity should be gradually increased from 5 to 9. The second, third and fourth five-minute periods repeat this pattern, except that the last period should finish at an intensity of 10.
Aerobic exercise is more effective for fat loss when done first thing in the morning, because it raises the metabolism for the remainder of the day, and because the body draws more heavily on its fat stores after fasting overnight.
