PROTEIN/CARBS?
BY CHRIS ACETO
Carbohydrates and protein have been misunderstood for years. Here are
the top
10 myths that plague your diet — and your physique
Sports nutrition is full of half-baked truths that often keep us from figuring
out just how to eat to maximise muscle gains or fat loss or both. One reason
for the confusion is that what people have been doing all along often conflicts
with what the latest research recommends. Here, m&f tackles the 10 biggest
carbohydrate and protein myths and untangles the misinformation that might
be holding you back from shaping your next 10 pounds of lean mass. Read, apply
and
enjoy your new muscle.
(Carb Myths)
CARB MYTH #1
CARBOHYDRATES MAKE YOU FAT
The real culprit is excess calories. Calories, the fuel derived from all three
macronutrients — carbohydrates, protein and dietary fat — increase
the body’s ability to manufacture bodyfat. Carbs have had a bum rap because
research shows that lower-carbohydrate diets are effective for obese individuals,
who are extremely overweight and seldom exercise. For the individual trying
to build metabolically active
muscle tissue, carbs are a must-have. They fuel the body for exercise, help
drive protein into muscles for growth and prevent the breakdown of hard-earned
muscle
mass. In addition, weight-training individuals store a disproportionate amount
of their carbohydrate intake within muscles, called muscle glycogen. Only after
glycogen stores are full will carbs seriously impact on bodyfat stores.
MYTH BUSTER: How many carbs you should eat depends on your metabolism and how
hard you train, but a good starting point is about 2 grams per pound of bodyweight
per day.
CARB MYTH #2:
EATING CARBS AT NIGHT MAKES YOU FAT
Many dieters restrict their carb intake at night, limiting themselves to protein
powder, poultry, fish and vegetables sometime after 5 p.m. The belief is that
carbs eaten at night will unequivocally be stored as bodyfat, which is generally
true, as insulin sensitivity decreases at night. But here’s the problem:
if you train after work at 7 p.m. and finish by 9, you must eat carbohydrates
in your post-training meal to kick-start the muscle-building process. If you
avoid carbohydrates you’ll fail to support the growth process and, worse,
it could increase your cortisol, a hormone that can lower testosterone levels
and chew away muscle mass, causing a drop in your metabolic rate. That’s
the biggest concern, because when the metabolic rate declines, the body becomes
really good at storing bodyfat.
MYTH BUSTER: Consume 50 grams of carbohydrates (in addition to protein) to
kick-start the rebuilding process in the meal following your workout. If you
don’t
gain bodyfat from eating that much, boost it to 70–80 grams.
CARB MYTH #3
CARBS DON’T BUILD MUSCLE
Carbohydrates directly support muscle-building by fuelling muscles, helping
them to remain anabolic. Energy-starved muscles quickly fall out of an anabolic
state
and fail to grow. Carbs also create a special hormonal environment that plays
a critical role in growth — they initiate the release of insulin, which
increases protein uptake by muscles. Insulin also helps muscles take in testosterone,
the body’s chief muscle-building hormone.
MYTH BUSTER: Besides eating enough carbs for the day, eat an adequate portion
in your post-training meal, anywhere from 70–100 grams for growth and
repair.
CARB MYTH #4
YOU HAVE TO EAT LOW-GLYCAEMIC CARBS TO GET RIPPED
The glycaemic index is a tool that rates carbohydrates based on the speed at
which they digest. In theory, faster-digesting carbs are more efficient at
stimulating the fat-storing process. However, combining high-protein foods
with fast-digesting
carbs or fibre-rich vegetables such as broccoli, cauliflower, spinach, mushrooms
and green beans skews the index rating. For example, rice cakes — which
are digested very fast — digest markedly slower when combined with sliced
turkey, reduced-fat cheese or peanut butter, and even more slowly if you add
a small portion of vegetables. Combinations like this change the index rating
on carbs, relegating the glycaemic rating idea to mythical status.
MYTH BUSTER: The best meals for building mass and shedding fat come from combining
different foods — starchy carbs, protein and vegetables — along
with the small amounts of fat naturally occurring in protein foods.
CARB MYTH #5
MUSCLES HAVE TO BE FULLY CARB-LOADED FOR MAXIMUM MUSCLE GROWTH
Muscle glycogen — the collection of stored carbohydrates within muscles — provides
fuel for hard training and supports recovery, but glycogen reserves don’t
have to be topped off to maximise growth. You can run a car flat-out on half
a tank of petrol, and you can train like Mr. O on less than “full” glycogen
stores. Other factors play a large role in the muscle-building process, such
as protein intake and meal timing: Eat 5–7 times a day to maximise nutrient
uptake and absorption.
MYTH BUSTER: Eat a moderate-carbohydrate snack, about 30–40 grams of
carbs with 20 grams of protein, an hour before training. A small bowl of oats
with
protein powder mixed in is a favourite.
(Protein Myths)
PROTEIN MYTH #1
THE SKY’S THE LIMIT
Muscleheads continue to eat more and more protein yet often miss the mark in
understanding what causes growth. Sure, protein is a must, but higher-protein
diets are sometimes scant in carbohydrates. For muscle-building, you’re
better off eating more carbohydrates than protein because the two nutrients
work synergistically, upgrading the ability to drive aminos into muscles and
resulting
in growth.
MYTH BUSTER: Start with a minimum of 2 grams of carbohydrate and 1 gram of
protein per pound of bodyweight per day (see Protein Myth #3 for exceptions).
PROTEIN MYTH #2
ALL PROTEIN IS THE SAME
Nope, some proteins digest faster than others. Whey protein, egg whites and
some fish rapidly reach the bloodstream while casein protein, red meat, poultry
and
whole eggs are slower. Faster-digesting proteins are best in the morning to
reverse the overnight fast when the body sometimes falls out of a growth state.
They’re
also best before and after training, when the body needs immediate sources
of protein to help prevent muscle breakdown. At other times of day, slower-digesting
proteins do just fine.
MYTH BUSTER: Have your whey protein shakes early in the day and after a workout,
and save casein for later in the day.
PROTEIN MYTH #3
1 GRAM PER POUND OF BODYWEIGHT RULES THE DAY
We’re told the body needs a gram of protein per pound of bodyweight daily.
Guess what? Though fairly accurate, that number is an estimate. When calories
drop, such as when you eat drastically less fat or reduce carbs to shed bodyfat,
you’ll need more protein, upward of 1.5 grams per pound, to keep from burning
muscle tissue for energy. Training intensity, frequency and duration play a role,
too. The harder you train and the more muscle damage you incur, the more protein
you need to rebuild those damaged fibres. If you train six days a week, you’ll
need more protein than if you trained just four times, and if your workouts
are longer in duration, you might need to bump your protein above the 1-gram
benchmark.
MYTH BUSTER: Many who complain of inferior muscle recovery might just need
more protein — between 1.2 grams and 1.5 grams per pound of bodyweight
daily.
PROTEIN MYTH #4
YOU NEED PROTEIN SUPPLEMENTS TO GROW
Though fairly economical and extremely convenient, protein powders don’t
have to be part of a muscle-building diet. Muscle-building can be achieved with
real food. Just ask three-time Arnold Classic champion Jay Cutler: when he started
out, he couldn’t afford supplements, so he consumed up to 50 egg whites
a day and a couple of pounds of chicken, compliments of the farm he lived on
as a 19-year-old. In the next two years, eating nothing but egg whites, chicken,
oatmeal, pasta and potatoes, Jay gained an amazing 50 pounds of mass. Powders
are good, but growth still boils down to eating sufficient protein, carbohydrates
and calories to repair and fuel the body.
MYTH BUSTER: For convenience, many trainees find that alternating a solid meal
with a protein shake is an ideal way to eat up to seven times a day.
PROTEIN MYTH #5
PROTEIN CAN’T MAKE YOU FAT
Excess anything — protein, carbohydrates or dietary fat — can make
you fat. If you require 2,600 calories daily, meet that requirement yet still
eat a chicken meal and a protein shake above that amount, the excess protein
will be sent to the liver, converted to glucose and eventually make its way to
fat stores. Though protein seems to be a little less efficient at making bodyfat
than dietary fat and carbohydrates, don’t fall into the trap of believing
protein is exempt from making and storing bodyfat.
MYTH BUSTER: Don’t just count protein and carbs throughout the day; count
all calories to ensure you won’t exceed your daily calorific requirements.
