Weight loss programs often have big claims. Understand the "science" behind weight loss, and you'll zero in on the achievable ones.
The key is to try not to simply accept or reject the the "claim" but to see which kind of program is scientifically more viable -- and therefore capable of living up to its claim. To understand weight gain and weight loss thus, we need to understand that the body actually has a three-sided energy equation ...
... there is ENERGY INPUT (what we eat), ENERGY OUTPUT (what we use in activity) and ENERGY STORED (fat layer in the body is solidified stored energy).
The first error most people make is to consider only energy input and output in their theories of weight loss programs... so they simply try to either eat less or exercise more to affect their weight. Whereas, it's very important to shine some light on the third side to this energy equation -- and that is "energy stored"!
What happens in the body of someone fat, overweight and not fit? Too much input for all the wrong reasons, too less output through a less active lifestyle, and too much storage therefore (i.e. excess fat build up).
Now let's look at one important scientific factor that is not visible in this equation but most drastically affects all weight loss programs ... the psychology of the mind!
Very many people believe that the mind makes the body crave food and hate exercise! But the mind does not thus directly affect the input and output of energy ... it's very important to understand this.
The mind actually affects the the third item -- the "storage issues" of energy. A mind that subliminally perceives the outer environment we live in as difficult, hostile, threatening etc. sends signals to the body that fat stores must be fortified in case of sudden or future crisis needs. And an obedient body responds!
It automatically adjusts its behavior -- by creating a craving for energy input and creating a loathing for energy output. This is why our behavior seems involuntary, out of control. And this is why our weight loss programs seem unsustainable.
Now, just listen to this piece of logic and your doubts about how to lose weight fast will evaporate ... the right weight loss programs are ones that will help the mind send the right signals to the body! That's the secret.
That's why diets and pills don't work ... they can't change the mind's view of life. But exercise is one thing that can really alter our mind's threat perception and change it to an attitude of assertiveness.
How? When we set a physically challenging goal, when day after day we do physically what it takes, and against all odds, we reinforce to our mind its ability to conquer the environment. A strong dose of action taken on as a daily challenge, has a mind-strengthening quality, more than just a body-strengthening quality!
Even among exercises to take up, it's best to choose one that is itself non-threatening and natural -- for if the mind sees the exercise itself as too strenuous or threatening, the purpose is defeated. That's why the world of the long-term fit people is so full of those who have chosen walking -- the ultimate natural and non-threatening exercise, among all weight loss programs.
