Is it possible to slim down without dieting if i jog almost everyday for an hour? if so, how?

Regular exercise: can turn fat into muscle. You may not loose a lot of weight but you will be more trim and muscular. Peace and good health. Overall health can improve also.

Possible: But not that probable. There's a saying that goes, "You can't outrun a bad diet." 70-90% of weight loss is done through diet modification. Think about it this way: How long does it take to burn 100 calories? About 10 minutes. How long does it take to gain 100 calories? About 1 second. Hope this helps!
