How far would the human body need to go to lose 15-20 pounds

Diet has the biggest role in losing weight, then the exercising.

Explanation:

A person should be eating healthy in order to lose weight. Calorie deficit plays a very important role. Let's say your intake is 1800 kcal per day, to start losing weight, with appropriate exercise, it should be at least 1200 kcal. And it's not always how much you eat, but what you eat.

Everybody forgets how much calories regular drinks and alcoholic drinks contain.

Running is really helpful when it comes to losing weight. Walking the dog, going shopping or simply fast walking are also good variations, so you won't get bored of only doing one activity and your body won't get used to the mechanics of those activities. Swimming and cycling is also great.

When it comes to losing weight, it's approximately 2 lb a moth. A person will lose more weight in the first months of dieting and exercising, and less and less in the following months, unless they drop the calorie intake and upper their exercise routine.

The weight losing ratio with pounds through jogging must be 1 pound/ week.

Explanation:

Jogging involves the burning of calories. As, we know that 3,500 calories is equal to 1 pound of weight. In order to meet the goal of losing 20 pounds one needs to lose 1 pound per week.

That means 3,500 calories must be burnt in a week with regular jogging. So, if one burns 1 pound a week then it will take a time span of 140 days to lose a maximum of 20 pounds.
