Answer:
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.
