Only by fitness you will not lose weight efficiently, you have to watch your food intake, too. I'll show you why.
I’ve run over a video from Vox that answered a big concern of mine, and I guess, your’s, too: “Why having sports don’t make me lose that much weight?” Ok, it does a little, but not in a dramatic sense.
Well, it turns out, what you eat is equally important!
Here are some takeaways:
Physical activity (any movement that you do) only account for 10%-30% of your daily energy expenditure. The resting metabolism (that keeps your basic functions) and food breakdown has the most part.
That’s why when we exercise we feel a little more hungrier. Pay attention to not eat more than before your fitness life.
Also, when you have a fitness class in the morning, you are lazier in the rest of the day: elevator not the stairs, desk, not walks, snd so on.
The researchers found out that also when you slim down, the resting metabolism also slows down to conserve energy. But you eat the same, so you pick up weight again.
Other researchers studied a tribe in Tanzania that has all-day physical activity and they found out that they consume the same amount of energy as their peers at a desk in US. But they are slim. Because they don’t “overeat”!
Food companies (McDonalds, Coca-Cola) in the western culture present their products in subs with fitness like “if you do physical activity you can eat/drink whatever you want”. From us, of course!
So, it’s not impossible to lose weight by fitness, it’s just harder. We have to keep an eye on what we eat, also.
