The Truth About Carbohydrates

Carbohydrates are misunderstood and needlessly made confusing by so many self assuming experts. Carbohydrates are often viewed as the enemy and consuming them is a fate worse the death! Well not that bad, but why are so many people scared of Carbs?

It comes down to understanding. Understanding carbohydrates can be confusing because there are many different ways to categorize carbohydrates and (systems used to measure carbs). Here in lies the problem. So my solution is to give you a schooling in carbs, lets begin.

The eight main different types of carbohydrate are (with examples):

  • Low G.I Carbs (Sweet Potato)
  • Hi G.I (White potato)
  • Fibrous Carbs (Green Vegetables)
  • Starchy Carbs (Rice, Potato)
  • Refined Carbs (Processed sugar, white sugar or Soft Drink)
  • Natural Carbs (Fruit, Fructose)
  • Simple Carbs/Sugars (Glucose, Lollies)
  • Complex Carbs (broken down into 2 categories, fibrous and starchy)

Carbohydrates are broken down into sugars.

Types of Simple Carbohydrates (sugars) are:

-Monosaccharides:

  • Glucose (blood Sugar)
  • Fructose (fruit Sugar)
  • Galactose (found in Milk, makes up half the sugar Lactose)

-Disaccharides:

  • Sucrose (table sugar)
  • Lactose (dairy sugar)
  • Maltose (malt sugar)

From the list of eight carbohydrates (above), it’s easy to understand why some people can get confused. To add to these terms, the labels ‘good carbs’ and ‘bad carbs’ are often given to different types of carbohydrates

What exactly are Carbohydrates?

Carbohydrates are the body’s primary and premium fuel source. As carbohydrates digest they turn into glycogen. An excessive carbohydrate intake will result in “storage” in fat cells.

Exercise burns muscle glycogen and if the muscle stores of glycogen are not replaced the body’s system just slows down, lethargy sets in and this is not a desired state if you are concern with getting stronger and building muscle.

Severely depleted carbohydrate stores will ultimately result in a reduction of the body’s protein stores and lean tissue mass, obviously not the intent of any trainer.

So it’s a catch 22, we don’t want to consume so many carbohydrates that they are stored as fat and we don’t want to consume too little carbohydrates so that our glycogen supply causes muscle wastage and no energy during workouts thereby making building muscle and getting stronger nearly impossible.

SIMPLE CARBOHYDRATES

Simple carbohydrates have a ‘simple’ molecular structure which allows them to be digested very quickly, producing a rapid rise in blood sugar.

Simple carbohydrates can be both natural (good) or refined (bad).  Natural simple carbohydrates include fruit (fructose) and Lactose (found in dairy products). People can have problems digesting Lactose (Lactose intolerant). The term Hi GI carbs is often (but not always) another way of talking about simple carbohydrates.

Avoiding all simple carbs in natural foods (such as fruit) is not necessary but it is highly advisable to avoid simple-refined carbohydrates namely any products that contain white processed sugar. These are poison.

COMPLEX CARBOHYDRATES (Polysaccharides)

Complex Carbohydrates are made from thousands of sugar molecules linked together in long chains. As a result, these chains take longer to break down and digest compared with simple carbohydrates. The term Low GI is often used to describe complex carbohydrate digestion. There are two categories of complex carbohydrates:

  • Starchy Carbs
  • Fibrous Carbs

Starchy Carbohydrate sources:

Oats or Oatmeal

White Rice

Basmati or brown rice

White potato

Sweet potato

Rice cakes (make sure its 100% brown puffed rice and not maize or corn)

NOTE: Starchy carbs are higher in calories than fibrous carbs.

Fibrous Carbohydrate sources:

Broccoli

Lettuce

Cauliflower

Zucchini

Tomatoes

Asparagus

Green Beans

Squash

Cucumber

Spinach

*Most Green Vegetables fit into this category

REFINED CARBOHYDRATES- THE BAD CARBOHYDRATE

(AKA Refined sugar, Processed carbs or Bad carbs)

Refined carbohydrates are complex carbohydrates (starches) that have been highly processed to remove the bran, hull, fiber and most of the nutrient from the grain. In essence, refined carbohydrates are complex carbohydrates that are changed into simple carbohydrates with high concentrations of sugar. They are “empty calories”- Empty in a sense that they are nutritionally void but at the same time they are loaded with ‘bad’ calories.

Sucrose (white table sugar) is a perfect example of an empty calorie. It has no vitamins, no minerals, and no proteins, just calories. It does nothing positive for the body. A brief study of my clients food diaries show that they will consciously restrict wholefood carbohydrates such as sweet potato, bread and pasta in the belief that they are eating “low carb” yet their diets include foods such as soft drinks, donuts and ice cream not realising that these foods are much worse.

A pet peeve of mine is when people restrict their carb intake but then eat chocolate and or drink soft drinks or sugar laden energy drinks. These are carbs! Not just that, they are bad carbs! People will cut things like bread, potato and paste, only to mess it up by eating things that are ten times worse.

Manufactures promote and market refined carbohydrate products as ‘fat-free’ or ‘low G.I”, this over hyped marketing leads to confusion as to what nutrients the product actually contains. For what ever reason people don’t understand that these products are full of bad carbs. A great example of this is Milo (in Australia), it’s classified as “low GI” but the sugar content is through the roof. The marketing of this product has made people actually think its low in sugar and a great source of energy.

For a strange reason, be it misinformation, cleaver marketing or just plain stupidity, people don’t necessarily see these foods as ‘carbs’ per-say. Reality is they are the worst type of carbohydrate- Refined carbohydrate. To an extent, people want to be sold ‘sweet things’ because they enjoy them.

Refined carbohydrate products have a very long shelf life. Big businesses dealing in food sales prefer a product that does not expire as there is never any loss from over production. From a business stand point refined carbohydrates are a ‘hot product’, from a health stand point they are poison. Marketing of these products over time has seemed to confuse the masses of people to the point where people don’t know what’s in the food they eat or drink. It’s a common practise for manufactures to add vitamins and minerals to a refined product to give the impression that its healthy.

Restrictions on carbohydrate may cause cravings. Consuming refined carbohydrates cause Insulin to shoot up, this leads to more cravings! There is a hormonal reason why people crave foods. To counter-act unwanted hormone reactions, pre-planning a correct carbohydrate intake must take place so cravings can be stoped dead in their tracks (or limited).

The body is a smart system, if you restrict carbohydrates you deplete muscle glycogen and energy so the body does what it’s designed to do, it sends out signal in the form of cravings so you can quickly replenish its stores. Cravings signals want to be satiated and fast! Without a plan in place you find yourself searching the house for chocolate or ice cream (which obviously impacts fat loss goals in a negative way.)

Being more sensible about carbohydrate selection and timing will stabilise blood sugar and fight off cravings. Again, it comes back to sensible planning.

NOTE: If one is to be successful in pursuit of their health and fitness goals, clear distinctions must be made between unnecessary cravings, genuine cravings and discipline. Unnecessary craving characteristics are:

  • Eating out of boredom,
  • Eating out of emotion,
  • Eating because it’s a special occasions or event
  • ‘The other person effect’, e.g someone else is having ice-cream so you want it too.
  • Lasts about 15 minutes

Cravings like these usually only last about 15 minutes. If you can wait 15 minutes and the cravings gone, it was an unnecessary craving

On the other hand genuine cravings are satiated by good food and will not go away after 15 minutes. The cravings (or hunger) will sit calmly in your stomach until you can eat.

Still uncertain about what refined carbs are?

Any uncertainty about food containing refined carbs, always check the ingredients list. Refined Carbohydrates are not always listed on nutrition fact panels as sugar. Be on the look out for products that carry any of the following ingredients:

  • Fructose corn Syrup
  • Corn syrup
  • Rice syrup
  • Sucrose
  • Glucose syrup
  • Invert sugar

These are different varieties of the refined carbs. If one of these is a main ingredient in a food then it should be avoided.

LOW CARB?

To decrease body fat, carbs are often the first macro nutrient to be restricted, next to saturated fats. A low carb strategy undeniably works to shed body fat. However, fibrous carbs should always be included in any nutritional plan.

Low Carb plans require Starchy Carbs to be reduced and optimally placed in the diet. This is important to understand as many people will restrict fibrous carbs which is often unnecessary. It must be understood before we proceed, there is a major deference between Fibrous Carbs (green vegetables) and Starchy Carbs. It may sound like I am repeating myself (I want to make it clear), don’t restrict Fibrous Carbs.

Fibrous Carbs contain very few calories and are loaded with vitamins and minerals and have much less impact on Insulin. Starchy carbs are higher in calories and have a greater impact on Insulin, thus why they need t be controlled.

For the majority of people, there are optimal times for starchy carb intake, they are:

  • Breakfast
  • Before training
  • After training

Depending upon your goal, a trainer may need to choose from simple and complex carbs at these times. Trainers wanting to lose weight will gain benefits from sticking to a simple approach and keeping all carbs sources at the above outlined times to complex sources.

Trainers who are leaner, and are wanting to gain more weight (in general) will gain benefits from including both simple and complex carbs at these times. They may also want to include a malto-dextrin or glucose drink during training sessions or a post workout supplement such as Surge for enhanced muscle recovery. In introducing pre, post or during workout shakes it’s recommended that the trainers’ body-fat does not exceed 15%. Leaner trainers have a better Insulin response therefore can merit the consumption of glucose around training.

The three times of the day as outlined above are not absolutes. However they are a great starting place. Sometimes in extreme phases of dieting (such as before a bodybuilding show) carbs may have to be cut from one or more of these times. For most of you who just want to get in great shape, consume a starchy carb source at all times as outlined above to get bigger, stronger and leaner.

When on low carbs, be on low carbs, don’t mess it up by eating spoons of sugar. Sugar is often the critical error in most people’s diet.

CARBOHYDRATE TO SUGAR RATIO

I designed the term “Carb to Sugar ratio’ when working with clients to help explain and simplify quality carb sources versus empty carb sources (using food labels). You may even use it to distinguish a complex and a simple carbohydrate.

What is the Carb source made up of? Using the food label, check the ‘Carbohydrate to Sugar ratio.’ Below is an example of rice cakes per 100 grams is given:

Rice Cake:

Total Carbs 77g
-Sugar Less than 1g

Compare this with Marshmallows per 100 grams

Marshmallow

Total Carbs 83.3g
-Sugar 64.8g

This is an example of a very bad carbohydrate source. Over half of this product is sugar. It is recommended that you back up this ratio test with checking the ingredients. In the case above (the marshmallow) glucose syrup was found on the ingredients list which of course is a refined carb/sugar.

When using this method, there are exclusions to be aware of. For example, glucose powder will read 100% sugar on the label, however after training it may have its use for the RIGHT PERSON. Fruit is also another exemption of this tool as it contains natural sugars. Remember to check ingredients for refined sugar when using this tool.

As a general rule, try to keep sugar as low as possible when looking at carbohydrate and sugar ratios, particular when containing refined sugar.

How To Survive… And Thrive On a Diet!

There is an inherent problem with all calorie-deficit diets. They are catabolic. Thats right, take as many anti-catabolic supplements as you like but if you are in calorie deficit… you are in a catabolic state.

Tricking The Body

However, there are many little ways to trick the body so that most of the catabolism is confined to fat tissue and muscle tissue is preserved. In this article, I will give tips how to stay out of muscle catabolism (breakdown) and in fat catabolism.

First off, let’s talk about what kind of diet you should be on. There have been many diet fads in the past few years, with ketogenic diets becoming more and more popular among bodybuilders… and for good reason, they work very well for fat loss.

However, if you have an extended period of time to lose fat and would like to preserve as much muscle as possible I suggest another alternative. To start off this discussion, let’s use, for example, a person who weighs 170 lbs and who’s daily calorie maintenance level is 2500.

To lose one pound of fat per week (a rough estimate of optimal fat loss) they should be eating 2000 calories per day (-500 calories below maintenance).

The Hardcore Bodybuilders

Now, if this person is a hard-training bodybuilder (which I assume is most of my audience) they will probably want around 1.3g protein per pound bodyweight since they will be in calorie deficit and in need of more protein to preserve muscle mass.

That would put their protein count at 220 grams per day (880 kcals from protein). Now we’ll move on to fat intake. The basal fat level for any kind of diet should consist of 20% of calories from fat as a minimum to ensure proper hormonal function among other things (skin tone, nails, etc).

That means they’ll need about 45g of fat (roughly 400 kcals) from fat. Now here is where I differ from people who advocate keto diets for bodybuilders. Having established the basal level for protein and fat we now have appox. 720 kcals left to work with.

People who are advocates of keto diets would suggest that you make most of these 720 kcals come from fats, so that your carbohydrates are kept low enough to allow you to go into ketogenesis. However, I suggest taking these extra calories and adding them towards the carbohydrate count, in this particular person’s case this amounts to about 180g of carbs per day.

Why Carbs?

Why carbs instead of fat? Well there are a couple of reasons… the main reason being that carbs are more protein-sparing than fats. Indeed, glycolysis (breakdown of glucose to manufacture ATP) is much more efficient than fat oxidation. Now I’m sure your asking what I mean by protein sparing.

When the body is in calorie deficit it may actually oxidize amino acids from protein you eat to make ATP, it may even oxidize the muscle tissue itself for energy.

Since carbs are more protein sparing than fats it only makes sense that if our goal is muscle preservation during dieting that we should not neglect carbohydrates. Now before I continue lets take another look at this individual…

  • Weight     170 lbs
  • Maintenance daily caloric intake     2500 kcals
  • Diet calorie intake     2000 kcals
  • Protein     220g
  • Carbs     180g
  • Fat     45g

*Keys to maintaining muscle while on a lowered calorie diet*

Timing Of Carbohydrate Intake

The times when carbohydrates should be consumed are the times at which the body is under the greatest stress and is in the most danger of muscle catabolism. These times are in the morning after awakening, workouts, and cardio sessions.

The optimum way work this diet would be to do your lifting session about an hour after breakfast. If you can in fact do this then here is how I would ration your carbohydrate intake: 40% of daily carbs pre-workout, 45% of daily carbs with post workout meal, 10% with 3rd meal and the other 5% should come from vegetables sources the rest of the day such as salads, broccoli, etc. Rationing your carbohydrates this way does several things.

  • Repletes your glycogen stores, thus giving you more energy for your workout.
  • Causes insulin to be released (from breakfast meal) during training which will blunt the release of other catabolic hormones. The post workout carbs will help replete glycogen stores and jump start your recovery by releasing more insulin.
  • The carbs will be very protein sparing, thus helping prevent muscle catabolism while your body is under stress.

During these high carb meals, you should try to keep your fat intake as low as possible as it will interfere with the release of insulin and will add unneeded calories to these meals. The bulk of your fat intake should be spread evenly over your low carbohydrate meals.

Protein

Protein intake should be even throughout the day although there would probably be a slight advantage to consuming a bit more protein post workout and before your retire for the night.

Now let’s discuss the type of carbs you will want to consume. Pre-workout focus on consuming medium to slow digesting carbohydrates such as oatmeal and bran cereal. Try to stay away from fructose at all times. Your post workout meal should actually be 2 meals, 1 meal immediately after your workout (a liquid meal preferably) and another meal 45 minutes later.

For the individual in question, their first meal post workout a shake containing a blend of proteins (egg, whey, and casein) along with about 20g dextrose and 25g maltodextrin would be an optimal mix. These carbs are absorbed quickly and will cause a quick and large rise in insulin. 45 minutes later, however, this insulin spike will begin to actually crash.

This is where they will want to consume another 35g of slow digesting carbs in order to stabilize their insulin levels and give their body slow digesting carbs to continue to aid in the recovery process. Once again, oatmeal, oat bran, bran cereal are all good choices. I would also suggest a small protein source such as a small (3.5 oz) chicken breast.
