Understanding the theory of adaptation (see previous article,
Adaptation I) will give you the tools to evaluate your diet and
daily routine. If you have any question about whether something
is good for you, always examine both the immediate
effects and the adaptation effects equally. This
article will look at various examples of adaptation and
practical advice based on this important theory.
Walking Is walking for a long time a good way of losing
weight? Look at it this way: the direct effect is that calories
are burnt over that period, and you will by using your fat
stores for fuel because it is aerobic exercise. So that’s a
positive: you’re burning calories, and as long as you don’t eat
too much food, you’re losing weight. But what will be the
adaptation? You’re telling your body that you will need
to walk for a long amount of time to find food. So, how will
your body adapt to make you a better walker? Expending energy
faster? Burning fat easily? NO WAY. If you need to walk through
the savanna for a long time, you want your body to conserve
as much energy (fat) as possible and retain as much water as
possible. This is the opposite of your goal, you will not
lose weight in the long-term, so it is not an optimal solution.
Sprinting
What about high-intensity exercise? The immediate effect is to
burn calories in your blood, but there isn’t enough time to
start burning fat. Your muscles may burn with lactic acid, and
you can’t keep it up for very long. That isn’t too good, because
you won’t burn as many calories as you did walking. But is the
adaptation going in the correct direction? Your body will try to
make you a better runner by making calories available to you
at a moment’s notice to fuel your run (burning fat faster), and
will try to get rid of the fat that is slowing you down.
This is a great adaptation.
The best advice regarding exercise for weight loss in accordance
with adaptation is this: warm up by doing a fast walk for 10-15
minutes, so that your body goes into a fat-burning mode. Then,
turn up the intensity as high as you can and speed through the
next 10-15 minutes. This can be running, climbing stairs,
bicycling or whatever activity you like. I recommend a
stationary bike because the risk of falling or hurting
your joints is minimized. If you do this before breakfast,
you’re also training your body to use stored energy (fat)
instead of energy from food in your stomach.
If You Could Be an Animal…
If your physique could resemble an animal’s, which animal would
you choose? Try to ignore symbolism, and just pick an animal
whose body composition you’d like to approach. Many men would
choose a lion and many women would choose a gazelle. These
animals have adapted to get the bodies they have, and their
adaptation, like yours, is based on how they behave day to day.
So how do these animals behave? We can’t compare their
diets, because a gazelle is a herbivore, a lion is a carnivore,
and humans are omnivores. However, we can look at their exercise
needs.
A lion, to get food, has to sprint for up to 5 minutes
until it grabs its prey, which is usually pretty big. When it
does, it wrestles with it for up to 10 minutes, flexing
all its muscles and changing positions, putting all its force
against the other animal that is resisting with all its might.
This builds muscular strength and size and eliminates body fat.
A gazelle spends a lot of time eating, but each mouthful is
tiny. It takes a long time to eat, and never gorges. When
the grass all around it is bare, it bounces off to another place
to find food or water. The gazelle is highly alert because it is
vulnerable to attack, and often twitches or fidgets to
make sure it can escape quickly. When it is attacked, it runs
(bounces) incredibly fast for up to 20 minutes until it is
safely out of danger. This activity makes it long and slender as
an adaptation to its environment.
Don’t be a house cat. Many cats are overweight because
their environment doesn’t challenge them to run to catch food
(or avoid being caught), and sleep or lie around for 18 hours a
day. If you have a desk-job, and then watch TV on the couch,
that is exactly what you are doing.
Three Squares
Should you eat only three meals a day and avoid snacking to lose
weight? Well, you will be consuming fewer calories, so that’s a
plus. However, the bigger effect is this: your body will
think food is rare and that you may starve. If you go 5 or 6
hours between meals, or if you skip breakfast and go 16 hours or
so without food, what else could your body possibly conclude?
Your brain can’t tell your cells “don’t worry, we’re trying to
lose weight,” because your intentions don’t mean anything to
your organs. Your organs react and adapt to the stimuli
presented to them. So they think that you’re in the
desert. How do you survive in the desert? Like a camel:
Conserve as much food in your body as possible (fat), slow your
metabolism to prolong your life (so you’ll feel tired a lot),
and retain as much water as possible.
What about the opposite? What if you eat small portions every
two hours and drink water all the time? Your body will think
that you’re in a place where there is food whenever you need it,
like a jungle full of fruit trees and other easily furnished
food to eat. What is the reaction? Hooray! Better to speed up
the metabolism, so that the stomach is finished digesting the
previous meal before the next one comes; no need to store fat
that is just leeching circulation and water; and get rid of any
excess water in the system, because fresh water is constantly
coming in. This is in line with your weight loss goals, so this
is the route to take.
Calories: Eat less or burn more?
The final effect of your body’s great adaptation potential is
the question of which is more effective: eating fewer calories
or burning more calories with exercise? Let’s look at these two
propositions in terms of adaptation.
If you first remove a significant number of calories from your
diet, you will feel less energetic (because calories are
energy), therefore, you won’t feel like exercising, and you
won’t be able to exercise for as long. On the other hand, if you
start exercising more each day, it will make you hungrier
(because your body knows it’s not getting enough calories to
support this new activity), but as long as you try to keep your
eating habits the same and pay attention to satiety by eating
foods that make you feel full, you’ll feel great, your endurance
will improve and your overall health will keep getting better.
At that point, if you reduce the calories in your diet, then you
will be able to cope with slightly less energy, because your
body will already be more efficient at using that energy to fuel
your exercise.
A Summary
To conclude, in terms of exercise: warm up to get the
circulation going with a fast walk for about 20 minutes, then do
a high intensity activity for about 10 minutes. The best to do
that is before breakfast. In terms of diet: try to reduce your
calories overall, but divide them among small meals all day.
Never eat a big meal, but snack every hour or two on something
healthy. Also, drink as much water as you possibly can all day.
These practices are optimized for your body’s natural reactions,
so that you will be training your body to lose weight. And
whenever you hear diet advice, try to look past the immediate
effects and look at it from the perspective of Adaptation.
