CARBS, FATS AND PROTEIN….
These are the 3 nutrients in food we need to be concerned with as athletes. And there are a certain amount of each that should be consumed per day, dependant upon goals.
CARBS
Carbohydrates are the bodies “fuel” that it uses whenever physical activity is performed. From breathing and walking around to full contact Thai Boxing or benching some heavy iron; it all uses different amounts of carbs and if there are not enough carbs to fuel the exercise, your body will cannibalise your own muscles for fuel. Bad times, however it’s not as simple as “eat carbs” as there are 2 types of carbohydrate…
COMPLEX CARBS
These are the carbs we want to eat. They’re “slow” burning and so provide a longer lasting and more steady input of fuel for the body. Such carbs are found in Brown Rich, Wholemeal Pastas and Potatos
SIMPLE CARBS
These are basically sugars and are quickly passed into the blood stream. At times this can be beneficial (immediately after exercise) but if your body doesn’t use this energy quickly, any excess will be removed from your blood stream by the hormone; insulin, and because the body will not waste energy, it will be stored as bodyfat. And thats bad. Very bad. Simple carbs are found in chocolate bars, cakes and sodas, etc…
SEPERATING THE CARBS
Look on a food package; it’ll have “carbs” in the table of nutrients, and underneath it’ll have “of which sugars” basically if you subtract the “sugars” from “carbs” you’ll have the total amount of complex carbs in the food
PROTEIN
Protein are the “building blocks” of the body and are used in the construction and maintenance of muscle tissue, tendons, skin cells and much more. Protein is also believed to have fat metabolising properties. One important fact about protein, however, is that the body is incapable of storing protein for later use (unlike fats and carbs) and within a few hours of consumption; the protein will be flushed out of the body, thereby requiring a constant input of protein. A lack of protein will result in muscular atrophy and a loss in size and strength.
FATS
Fats do NOT necessarily make you fat. Infact, if you are trying to lose bodyfat and resort to cutting out fats from your diet; it can have a detrimental effect on your efforts! Fats are used by the body for lubricating joints, helping transport fat soluble vitamins around the body and also in growth and repair. They are also produce more energy than carbohydrate, though they are not as quickly accessed.
HOW MUCH!?
Ok, so now you know what they do…how much of each nutrient should you eat per day?
It is generally accepted that, in order to maintain your current muscle mass, you need to consume 1g of protein per lb of bodyweight. So long as you keep adequate protein coming into your body, you will maintain your muscle and burn bodyfat with exercise.
Each of the 3 main nutrients contain calories. Carbohydrate and Protein contain, essentially, 4 cals per g of carb or protein. Fats contain 9 cals per g.
For our examples, we’ll use a fictional 175lb person. First, we’ll look at nutrient levels for fat loss, then for lean muscle gain (as athletes don’t require bulk muscle; it looks great on the beach, but doesn’t do much for you in the ring or on the pitch)
FAT LOSS: (based on 1.5g carb and protein per lb bodyfat and 10% of your calorie intake coming by way of fats)
Protein: 260
Carbs: 260
Fat: 30
Cals: 2350
LEAN MASS GAIN
based on 1.5g protein, 2g carbs and 20% total calories coming from fats)
Protein: 260g
Carbs: 350g
Fat: 85g
Cals: 3500
