Should we focus on high intensity cardio or strength training to burn fat? Is exercising first thing in the morning really better than squeezing in an exercise session at another time during the day? Find out the truth behind some of the most popular fat burning claims.
The afflux of health and fitness related information coming
our way on a regular basis can sometimes seem like a double edge
sword: on the one hand it gives us extra tools and tips to tweak
our behaviors and increase our motivation, while on the other hand
it heightens the confusion as a lot of contradictory information
comes our way.
Fortunately, half truths and misinterpretations are eventually
exposed and we can get a better grasp as to what the best options
we have to reach our objectives as planned. Fat burning is perhaps
one of the most controversial subjects as new theories constantly
emerge and we are left trying to discern between facts and fiction.
Let's examine some of the long-held theories and see the truth
behind them:
Exercising in the morning burns more fat
The theory is that at night the body uses carbohydrates and by the
morning the only fuel left is fat and therefore, the body burns
more fat if the exercise session is done in the morning. Turns out,
however, that early birds might not have all the benefits
proclaimed.
However, carbohydrates are stored in the liver as well as muscles
and while the glycogen stored in the liver is used by the body, the
glycogen (the form in which carbohydrates are stored) from the
muscles can only be utilized by muscles, so the theory doesn't hold
much water. Forget exercising on empty stomach too: the effects are
marginal at best and the strategy might even work against you as
you might not be able to push yourself as hard and you will
diminish calorie burn too.
Longer lower intensity workouts burn more fat than medium and
high intensity ones
It is indeed true that lower intensity exercises rely primarily on
fat as fuel, however, for the claim to be true the workout would
have to extend to several hours. Also, while the percentage of fat
burned might be higher, the total calorie burn will eventually be
lower and thus, the amount of fat shed will also be lower, so,
unfortunately, replacing challenging workouts might not be all that
beneficial.
Strength training/Cardio is better for burning fat
After cardio has taken the weight loss spotlight for the number of
calories burned, strength training proponents have argued that
weight training is better as it enables you to burn fat long after
the workout is over. While neither of these theories are inherently
wrong, it's important to understand that they work best together.
Focusing exclusively on cardio will result in muscle loss as pounds
melt, while focusing solely on strength training will delay weight
loss progress. Furthermore, new studies suggests that doing both in
the same exercise session will enable you to eat less.
A calorie is a calorie
Sounds logical enough, doesn't it? As a measure of energy, a
calorie is indeed a calorie. However, from a metabolic standpoint,
the food source really does matter as the body processes the foods
differently. Our bodies crave macronutrients not calories, so
focusing on clean eating is of utmost importance when it comes to
accelerating metabolism. Focusing on nutrient dense foods will have
a much more beneficial effect on metabolism than simply cutting
calories.
