If you want to successfully complete your 4-year weight loss plan, you must make it a part of your life. You can think for yourself: for a young man, four years is not a tiny time number. The university curriculum is much more relaxed than that of middle school, so you will have a lot of time to realize your wishes.
I suggest you get into the habit of "walking" after meals. But this habit is not simple. After going to college, find a route with a round-trip distance of 3000 meters near your college, your familiar environment and your favorite environment. Take a walk more than three times a week. I'm afraid the weight loss figure after four years is much more ideal than what you asked for.
Your request is as simple as that! My answer is the same.
Tip: The lines around your home are for winter and summer vacations.
