But when I think about it, having the kind of body that easily puts on weight was perhaps a blessing in disguise. In other words, if I don’t want to gain weight I have to work out hard every day, watch what I eat, and cut down on indulgences. Life can be tough, but as long as you don’t stint on the effort, your metabolism will greatly improve with these habits, and you’ll end up much healthier, not to mention stronger.
