You’ve probably read numerous articles on dieting for a bodybuilding
competition. Too many of these articles use unconventional techniques with no
scientific basis. This is a solid explanation of basic fundamentals for
effectively dieting your body fat down in preparation for a contest. It's
scientifically based and it's specific for contest preparation.
You need an accurate assessment of your body composition. Have your body fat
percentage measured at a health club, a local university (by the exercise
physiology department), or a local hospital. You should aim for a body fat
percentage between 2-4% by contest time; so you must determine how much fat you
have to lose. For example, a bodybuilder weighs 200 pounds with 10% body fat, so
he has 20 pounds of fat (200 x .10). To get down to 2% body fat, he would need
to lose 16 pounds of fat.
You must have a basic understanding of nutrition. Here is a quick run down of the most important things you need to know in order to make a pre contest diet. A pre contest diet is very restrictive and potentially unhealthy. Therefore, the diet should be done in the shortest time possible. In fact, your off season body fat should not exceed 8-10%. If your body fat is within this range it should take 12-16 weeks to get it down to 2-4% body fat, which is usually the body fat of a bodybuilder on the day of the contest.
Number of Calories Per Day
In order to find out how many
calories you need in a day you must use a precise measurement. This is done by
using the same method registered dietitians use, the Harris Benedict
Equation. To make this equation easier:
We now have to figure out how many grams of protein, carbohydrate, and fat to
eat in each meal by dividing the calories among the macro nutrients, i.e.
protein, carbohydrates, and fats. The following distribution is for pre contest
dieting only. These percentages should not be followed for more than 16 weeks at
a time:
| Protein | 40-45% |
| Carbohydrates | 45-50% |
| Fat* | 10-15% |
Let us assume that the person dieting needs 216 calories per meal, 40%
protein, 50% carbohydrate, and 10% fat. The following formulas would be used:
| MACRO NUTRIENT |
TOTAL CALORIES PER MEAL |
x | % | = | CALORIES* |
| Protein | 216 |
x | .40 | = | 86 |
| Carbohydrate | 216 |
x | .50 | = | 108 |
| Fat | 216 |
x | .10 | = | 22 |
| MACRO NUTRIENT |
CALORIES PER GRAM |
| Protein | 4 |
| Carbohydrate | 4 |
| Fat | 9 |
| MACRO NUTRIENT |

Now you know the exact number of grams of protein, carbohydrates, and fat that should be eaten at each meal.
Okay, now you know the grams for each macronutrient for each meal, but you need to know what the best foods are for losing body fat. Listed below are the best sources of each macronutrient excluding fat because it is in lean meats and protein powders you are eating.
Combine any three, one from each column, and you have a pre-contest meal. Portion size will depend on the amount of grams you are permitted at each meal.
| PROTEIN | CARBOHYDRATE | FIBER |
| Turkey Breast | Oatmeal | Broccoli |
| Designer Protein Powder | Rice | Kale |
| Chicken Breast | Whole Wheat Bread | Spinach |
| Tuna | Baked Potato | Bell Peppers |
| Sole or Flounder | Rice Cake | Cauliflower |
| Red Snapper | Grits | Brocco-flower |
| Perch | Cream of Wheat | Green Leafy Lettuce |
| Halibut | Farina | Romaine Lettuce |
| Egg Whites | Pasta | Collard Greens |
It is very important to monitor your progress accurately. Track your
weight with a scale, your measurements with a tape measure, and your body fat
percentage with skinfold calipers or another accurate body-fat measure. Of
course the most accurate measure is the mirror. If you are looking defined
you will know it. However, always get another critical opinion that will tell
you the truth regardless of how cruel it is… for me it is my brother.
Even if you are doing everything right, your body doesn't always respond like you want it to. This is the purpose for continually monitoring your progress. If you are not losing body-fat as quickly as you'd like add aerobic exercise to your routine doing 20 minutes per workout separate from your weight training. Initially do the aerobic exercise 2-3 times per week; if your body-fat still has not decreased increase the aerobics to 4-5 times per week. As a natural bodybuilder your body is prone to catabolism which can result from extended aerobic work-outs and lead to loss of hard earned muscle.
On the other hand, you may lose weight too rapidly which can accompany muscle loss. In this case you would slightly increase your protein and carbohydrate intake. Any alterations should be done in small increments and recorded carefully.
Every pre-contest diet is a learning experience. In order to learn from each experience you must accurately record every detail; what you eat, how you train, your body weight, your body composition, your measurements, and how you feel.
If this process seems a little complex, it is! Dieting is a science and each body has slightly different laws by which they function. However, we are all alike in how we gain and lose body-fat. It is merely a question of how much or how little we need to obtain the desired result.
