You need to know what fitness is first. Fitness has two functions: increasing muscle and reducing fat. It drives the muscles of the body through exercise, making people's metabolic function more vigorous. And what is the easy fat constitution? Simply put, digestion is so good that everything you eat will become a very nutritious substance. The two have nothing in common. Do you want to make your digestive system poor through fitness? It's hard, isn't it? Unless you keep exercising and eat poorly, it may be effective.
In fact, many of us have improved our stomachs and digestive systems because of fitness, and it is easier to gain weight by eating. This is normal. You can ask anyone who works out, especially girls who were thin before. After fitness, the weight is basically more than ten kilograms. Why? It is because fitness has improved their physique and absorption, their demand for food is more than before, and their digestive ability is stronger than before. Isn't this a fattening physique?
I'm like this myself. I have been wandering around 90 pounds before, and I like to eat a lot of snacks! But my stomach is not good, and I always can't digest it, so I don't gain much weight. But after fitness, I don't feel indigestion at all, and I have gained ten pounds. So do many of my friends who work out.
So you can't change your obese constitution through fitness. You can only make your figure look thinner, slimmer, or better. If you change your physique, find another way. But in fact, we really don't need to care too much about weight. It's actually good if fitness can make you thinner, isn't it?
