I am hobby jogger, who has lost 175 pounds. I love to run, about 60 miles per week. I love the long run, usually four or five 20+ mile long runs during marathon built up. I usually run every day with two workouts per week. I love marathon training, a slow 4 hour PR. Though I love to run and I have lost a ton of weight, I personally think running is only 1/10th of weight loss process. It is mostly nutrition manipulation. Before I started losing weight, I drank a case of Coke a day and ate a lot pizza and junk food. Now, I live a low carb high fat diet, and hardly carb load for any run. My only point is that running is a small part. I could easily biked, lifted weights, golfed or any hobby to help me lose weight. I just love to run, to talk about running, and be around runners, even if I am the slowest of all. You can run to help lose weight, but you will need to control your carb intake and insulin spikes. I like to utilize time restriction eating patterns, so I am not always eating, too. I usually eat between 11AM and 6PM.
