Earn your carbs!
Carbohydrate is not an essential nutrient like fat or protein, and most of us eat far too much of it. The body only has so much storage space for carbohydrate. Once the liver and muscles are full... the excess is very easily converted into body fat. The average American walking around today is consuming way too many carbohydrates for their activity level. Usually by at least 200%.
How much is too much? Think about this... An elite level bodybuilder will consume around 300g of carbohydrate on a training day... and a competitive marathon runner will consume in the ballpark of 400g - 600g (based on 50% caloric intake from carbohydrate).
Are you either of the above? The answer is probably no... therefore your carbohydrate requirements are drastically less than the intakes mentioned... because your anaerobic energy requirements are far lower. After you’ve had a typical American breakfast of cereal, milk, orange juice, and maybe some sugar and milk in your coffee... you’ve already blown over the 100g mark! Which is about what you need over the course of the entire day assuming you are training at a moderate intensity.
Cycle your carbohydrate intake. Simply put, this can be interpreted as to eat higher carbohydrate on workout days and lower on days of rest. A good rule of thumb will be an intake of 100-150g on work days, 20-50g on rest days.
Just an idea of the carbohydrate value of typical American staples per serving. And let’s be honest... how many times do you actually follow the recommended ½ cup or 8fl oz?
1 cup Frosted Flakes - 36g
1 cup Oatmeal - 54g
8oz Milk - 12g
8 oz Juice - 27g
large apples/oranges - 32g
banana - 30g
So... keep an eye on that carbohydrate count. It is very easy to eat too much when consuming a standard American diet. Your carbohydrate intake should always mirror your activity level.
Manage your insulin
Insulin is responsible for delivering nutrients into muscle and fat cells. When it is elevated, the body is in a process of nutrient storage, and fat burning can be inhibited by over 50%. Obviously this is not what we want when trying to accomplish our goal of body fat reduction since we have too much in storage already, and the goal is to get rid of the excess.
Before going further, realize that insulin is not inherently a bad thing. It is a very important hormone that regulates muscle growth and proper partitioning of nutrients into specific cells. If you are trying to increase performance or build muscle... taking advantage of high insulin levels to jam pack muscles full of carbohydrate and amino acids can be a very good thing... more on that later on.
So how do we manage insulin to meet our goals?
● Avoid foods that have a large impact on insulin levels (especially pre workout). This includes all sugars, simple carbohydrates, beans, white potatoes, wheat products, dairy, and baked goods. Certain foods spike insulin more effectively than others. Carbohydrate in general is very effective because blood sugar must be stored immediately or it becomes a toxin to your body. Lean proteins and eggs will also stimulate an insulin release... but when consumed by themselves, the rise in blood sugar is minimal and the insulin is being used to store amino acids in the muscles instead of excess sugar into fat cells.
● Consume the majority of your carbohydrate in the post workout window. In the hours following exercise, nutrients are much more effectively stored in the muscle tissue and far less likely to be stored as fat. Attempt to get at least 75% of your carbohydrate requirements in AFTER exercise. Not before.
● Eat less frequently. That's right. Stick to two or three meals each day. Take advantage of the time between meals to utilize stored energy and achieve proper blood sugar regulation. It should not be a problem for a metabolically healthy individual to go many hours without eating... and is in fact a more natural rhythm than constantly propping up blood sugars with many small meals. If this is a problem for you, choose small, low carbohydrate snacks between eating until you can comfortably fast between meals. Eating many small meals per day to ‘stoke the metabolism’ has no scientific basis and is a recipe for disaster. No you will not ‘go into starvation mode’ (1) (2)
● Take advantage of insulin when you need to. On a workout day - try and keep the fat lower after your activity. When fat is consumed with a meal that causes a large insulin spike (with carbs for instance) it can be stored very easily as body fat. This is not usually a problem on a rest day, because the majority of kcals should be coming from proteins and fats if you are properly cycling carbohydrates as is recommended.
Mind your energy balance
The strategies mentioned here are meant to help optimize results. If you are eating more than you need... you will not lose weight. Period. Calories are still calories... and they DO count. To lose body fat effectively, you must be on a caloric deficit. Track your calories and build an understanding of what macro nutrients different foods contain. When eating on a normal schedule it is much easier to track food intake. It is also more conducive to good food choices. You can eat real meals! Attempting to maintain a neurotic stream of perfectly balanced rabbit snacks is a recipe for failure. We are trying to improve quality of life, not mechanize it into something unrecognizable. Whatever the number of meals you choose to have... make sure that they are in line with the energy recommendations you have set with your trainer or your own calculations.
