Carbohydrates!

Probably the trickiest macronutrient in my opinion to get a hold on for conditioning. Too many carbohydrates in your daily diet can easily contribute to fat cells, but too little carbohydrates in your diet will make you feel like ripping someone’s head off and limit your muscle building capability! I know people who have to eat less than 150g carbs/day to not put on fat and then there’s people like me who can eat up to 500g carbs/day without contributing to fat cells. It all comes down to your current conditioning, body type, and how much daily physical activity you get.

Carbohydrates are your fuel. Your body is genetically programmed to recognize carbohydrates as its main source of energy. Carbs are stored throughout the body, primarily in your liver, blood, and skeletal muscle. During exercise, we burn stored carbs in our muscle tissue which are then replaced by either stored carbs in your liver or “free” carbs floating in the blood.

Here’s where it gets tricky. If your blood sugar (carb) levels get too high and your muscle and liver carb capacities are fulfilled, where do you think those blood sugars get sent? Right to fat cells! So your carbohydrate needs will depend on your carbohydrate capacity (amount your body can store in the liver and skeletal muscle) and how much daily physical activity you do. There’s 2 ways to increase your carb needs and they both go hand and hand:

1. Increase your total capacity– one of the major benefits and adaptations that takes place from regularly engaging in resistance training is your body naturally increases it’s macronutrient capacities, primarily carbohydrates. The more you workout, the more your body will adapt to better handle that stress which means increasing it’s fuel (carbs) capacity.

2. Increase your total workload– Most of the time during exercise our bodies will tap into various fuel sources. You’ve probably heard that working out at a lower intensity will allow your body to use stored calories (fat) for fuel and working out at a higher intensity will burn more carbohydrates for fuel….and there is some truth to that; however, your body is never just burning carbohydrates or just burning fat for fuel. Rather, it’s more complex than that and usually a combination of the two depending on the intensity and type of exercise you’re doing. The bottom line is the best way to increase your carb capacity and workload is to do a combination of higher intensity training (such as cross training or vigorous cardio) and lower intensity training (such as resistance training or low/slow cardio). Both have their benefits for increasing your carb capacity and should be done regularly, but the combo will depend on your fitness goals. It’s pretty simple…the more you workout, the more carbohydrates you can eat.

The next tricky part with carbs is the amount, timing, and type. I could spend days writing about these topics, so I’m going to try to keep it simple.

Amount– we discussed above how your carb capacity is determined and how to increase it. In general, I suggest an active person to make at least 40% of their total calories carbohydrates (the USDA recommends 45-65%) . Carbohydrates have 4 calories/gram, so if you’re on a 2,000 calorie diet then you would start off eating roughly 200g carbs/day and then adjust up or down according to your weight goals/fluctuations, energy levels, and activity level.

Timing- there’s two times of the day when carbohydrates are crucial, even if you’re on a low-carb diet. Your first meal after you’ve slept and fasted for hopefully 6-8 hours and then immediately post-workout. Everyone should consume carbohydrates during these times as your carb stores are depleted during these times. As your physical activity decreases, so should your carbohydrate intake. I workout in the morning, so I have a first meal of complex and simple carbohydrates and then a meal with simple carbs right after my workout. Then for the rest of the day I start reducing and switching to more complex carbohydrates until dinner where I have very little (mainly vegetable sources of carbs).

Type- as to keep it simple we’ll just say there’s primarily two types of carbohydrates- simple and complex, even though with all the food items available today most are a combo of the two. Simple carbs (such as sugary beverages, cereals, breads, white rice, white potatos, etc…) will digest and absorb into your blood stream more quickly as opposed to complex carbs (fibrous carbs, brown rice, whole oats, sweet potatoes, etc…) which will digest and release into the blood stream more slowly. So, if you’re in a fasted or depleted state (like right when you wake up or right after vigorous exercise) it would make more sense to ingest simple carbs during that time to get your stores back up quickly and spare your muscle tissue from potential atrophy. Complex carbs should be utilized to keep a steady digestion of carbs into the blood stream to minimize insulin spikes when your liver and muscle capacities are already high.

Everyone’s needs and body is different, so trial and error is the only way to figure out your carbohydrate needs; however, I always recommend starting off with 40% carbohydrates of your total calories/day and adjusting accordingly. Keep the simple carbs for only post-workout and some at breakfast and then stick with more complex carbohydrates as you become less active.
