Pre contest dieting is about burning off body fat, retaining muscle, and displaying the physique to the competitor’s best advantage. Most competitors seem to start anywhere from 8 to 2 6 weeks in advance to get ready for a show. However, contest prep is a very individual process and really depends on how much fat needs to be burned and the speed of the competitor’s metabolism that results in the speed of fat loss. For example, a person needing to shed 20 pounds of fat will need la longer time for dieting than a person who only needs to shed 10 pounds of fat. Other factors involved are speed of the metabolism and levels of various fat burning hormones that can be affected by age, insulin sensitivity issues, and a variety of other factors. In other words, fat loss is never a linear process where you simply plug in a start weight and ending weight and travel a straight-line distance between points. Fat loss is just not that simple and in many contest preps there are unforeseen speed bumps to overcome. The keys to successful contest preparation are consistency and determination along with a positive mental outlook. Don’t get discouraged or panic and then crash diet. The fat loss will come.
If you are embarking on a contest diet for the first time, be aware of what is referred to as the metabolic shift phenomenon. This is when a diet is started and the individual loses 3-5 pounds the first week, and then nothing. This can go on for weeks or months. This is just your body acclimating to using insulin and other hormones to shed fat and not to store it. The metabolic shift is when the body decides it needs to start using stored fat as energy, and insulin and other hormones become more efficient at building or retaining muscle. If during this phase it is easy to continue to cut calories or add activity in an effort to speed things up, or to get discouraged a quit. This is where perseverance becomes key, as long as you do not reduce calories too much your body will eventually shift into gear and results will follow. If you remain patient and focus on consistency, strength improvements or small body changes and not the scale you will get through this initial hurdle.
Competition Body Fat Percentages
The fat that surrounds the spinal cord, heart, and vital organs is called essential fat and is necessary to sustain life. The lowest body fat percentage a person can have is their amount of essential fat. Essential fat is approximately 2 – 3% of total body weight for males, and ranges between 7 -10% for females. The difference in levels between genders is due to reproductive and hormonal factors. It is not likely for a competitor to reach the lowest possible body fat percentages though. If competitors can get within a couple percent of the lowest possible levels, they will display unbelievable definition. Most amateur regional level competitors don’t even get that low.
Figure and bikini competitors can come in at a wide variety of body fat percentages, largely depending on where and how their body holds fat, as well as the desired look of the competing organization. But generally speaking, body fat levels range from 8-15% for them, not nearly as low as female bodybuilders must go to show adequate definition. Most male bodybuilders will need to attain a lower single digit percentage to do well, but again what one body looks like at 7% may be totally different from another.
When it comes to body fat percentages it is best for the new competitor to disregard the numbers and just diet to the lowest body fat percentage they can attain. Go by the mirror and what your eyes tell you and not a mathematical reading because that may not be “your” best look.
How Long to Diet to Get Ready for a Show?
So, is there a way to know roughly how long someone will need to diet to get ready for a show? Well, here is one solid method, but it will not be accurate for everyone and will require some tweaks. First you need to determine your current body fat percentage, not just your body weight. There are a variety of ways to go about finding your fat levels. Many gyms offer body fat testing, and you can also get an inexpensive set of calipers with instructions from various online resources. Calipers (skin fold measurements), bioelectrical impedance (painless electrical current through the body) and near infrared reactance (light absorption and reflection) are the most common methods for obtaining body fat estimates and are available at most health clubs. The commercial sets, such as Accumeasure, use a plastic caliper with a one site measurement and chart to estimate your fat percentage. No matter what system you use the bottom line is that you will arrive at a percentage number and that percentage will give you the data you need to get a rough idea about how much fat you have. A rough idea because all methods of fat testing have errors built into them, and no test is perfect or “exact” and the error may be 3 -8% depending so use the numbers as a guideline or a start point. From there some simple math will get you the data you need to formulate your game plan. Here’s how it works:
In this example, the competitor is a female weighing 152 lbs. She has set a goal to be at 11% body fat for her competition. Say her test yields 18.6% body fat. 18.6% of 152 lbs. is: 0.186 x 152 lbs. = 28.27 lbs., so she currently has about 28.25 lbs. of body fat on her frame. A bodyweight of 152 lbs. – 28.25 lbs. = 123.75 lbs. of lean bodyweight (muscle, water, bones etc.). Using algebra, (who said that stuff would never get used in the real world?) to find to her goal of 11% body fat:
123.75 lbs./ x = 100% – 11%, or simply 0.89, 123.75 = 0.89x, 123.75/0.89 = x, 139 = x, so about 139 lbs. would be about the target 11% body fat. As a check, weight of 139 – lean bodyweight of 123.75=15.25 lbs. of fat, and 15.25/139=10.97% or 11% rounded).
28.25 lbs. of fat now – 15.25 lbs. of target fat = 12.75 lbs. to lose. Now that 12.75 pounds may be enough and produce the ideal look we are after or she may have to lose another few pounds to get to the goal “look”, but the data at least provides a guide. Now losing 1 -2 lbs. per week is a common rate of weight loss to shed body fat while maintaining muscle mass. Losing weight too quickly can come at the expense of losing muscle tissue. Figure on about 1.5 lbs. lost per week for this example. It would take 12.75 lbs./1.5 lbs. = 8.5 weeks of dieting to reach the target body fat level from this starting point. BUT remember, this is never a linear path! There will be obstacles, weeks of perfect dieting that yield less than the 1.5 pounds we seek or even no loss. This is when consistency and patience come in because we do not want to starve and risk a metabolic collapse. It’s common to have weeks of little fat loss, but as long as the progression is down the diet is still a success. So, what do we do to be ready for this? Try adding 25 % more time that factored in. So, the 8.5 weeks becomes 10.5 or round up to 11. And factor in a week to peak (we will cover that in a bit), and you have 12 weeks to be safe.
Note: When dieting, competitors should weigh themselves first thing in the morning each time. Water weight can vary several pounds throughout the day. By recording weights at the same time of day, like first thing upon waking after about 8 hours of fasting, ensures more accurate weight readings when monitoring weight loss from one week to the next.
When you start the diet another key piece of information is what your starting caloric intake is. To find that out simply record everything you eat for a week and weigh yourself every day. If you’re essentially the same weight from day 1 to day 7 then all you need to do is add up how many calories, you have eaten daily over the week and that is your caloric starting point. So, let’s say this same female tracked every morsel of food and put it into one of the many online or downloadable apps such as “Fit Day” and her result was 2,400 calories a day. This would be her base caloric level. Any reduction would result in a deficit and that deficit is what triggers fat loss. A good start would be about a 10% reduction along with an increase in activity, not a huge jump, just an increase. If you start by cutting calories in half and adding 70 minutes of cardio and another 60 minutes of weight training a day you will lose a lot of weight quickly but after 7 -10 days your body will release catabolic hormones that burn lean tissue (muscle) and other hormones that blunt fat loss. So, all the weight lost after that point is at the expense of muscle, not fat, which is why crash diets don’t work for bodybuilding. Why does this happen? 20 million years of evolution. The human body is designed to survive a famine and muscle is not good in starvation mode, so it’s burned first, before fat. So, a 10 -15% starting reduction is good to start the process.
Once you decide to begin your dieting for a contest, it becomes more important to know your food intake. You have to be a calorie and macronutrient counter at this point, at least until you gain plenty of experience with dieting down. To determine the breakdown of foods, you can use the online applications or go to a local bookstore and pick up a nutrition or food guide that lists the amount of carbs, protein, fats, sugars, sodium, etc. in foods. Begin dieting by eliminating all the junk food, excess sugars, and foods high in fat from your diet, and piece together your meals using a source of lean protein, a source of complex carbohydrates, and vegetables for fiber and vitamins and minerals. Also pick up a food scale and measuring cups. I do not know how many times I have seen people “guesstimate” 6 oz. only to have them weigh an item and see it is more like 9 oz. When you weigh and measure everything it is easy to cut more calories by simply cutting an ounce here or ¼ cup there.
There is no best ratio of carbs/proteins/fats as it differs greatly from individual to individual. A good place to start would be 50% carbohydrates, 30% proteins and 20% fats, but again this can vary widely based on insulin sensitivity, testosterone levels, muscle mass, etc. Many people do fine with these ratios, others feel they must take in a lower amount of carbs when dieting for a contest. Your body type, metabolism, and number of fat cells in your body (which is hereditary) can affect what works best for you. I suggest doing some research on the subject before you start but understand that a lot of what is talked about on many bodybuilding chat rooms is based on PED using competitors and will not be effect for natural athletes. And avoid some of the hype surrounding the “next great” fat loss trend. Any diet that recommends extremes is likely flawed.
You should be eating frequent meals (4-6), but the portions will become a little smaller the closer to the contest you get. As an example, say your normal food intake averages 3,500 calories per day. When you start dieting, you should maintain that number but use a stricter (cleaner) diet. In many cases simply cleaning the diet will result in some initial fat losses so don’t be too quick on the trigger when it comes to cutting calories. Counting calories serves as a gauge for where to go next. If after the first week you do not experience any weight loss, you should then cut your calories back 10 -15%. After another week you can gauge your progress and take it from there. For example, if you lose 5 pounds in a week, you should add some calories back to your daily diet. Ideally you should try to lose 1 -2 pounds per week. Much more than that would probably be at the expense of muscle, not the fat you want to get rid of. Continue adjusting your calories (or exercise amounts) as needed to continue to lose 1-2 pounds per week up until the week before your show. And remember, there will be bumps in the road so do not make massive cuts or by the end of the diet you will be down to too little calorie intake.
