This is what is happening to me. I started running, almost daily, for about an average of 45 minutes per run, on very hilly terrain. So, plenty of exercise, and a reduced calorie diet (about 1200 - 1500 per day, that doesn't leave me feeling hungry at all). I HAD been feeling a little bit down about things because I"d been working so hard, actually enjoying it, but had only lost about one kilogram (2.2 pounds? I think?) in the whole MONTH that I had been faithfully following my diet and exercise plan. That was, until, I started trying on some dresses that I hadn't worn in a while, and some shorts, because I had gotten too big for them and they FIT! Loosely! So, valuable lesson for me here - I've only lost about one kilo but I guess it comes down to how I'm feeling (great) and how my clothes are fitting. The journey will continue, and the fitter and healthier I get, the weight will come down naturally as my body adjusts to its new routine.
Actually I think my problem was that I was eating much more than I should after my workout.
The thing is that you think you can eat more because you were working out but I overestimated the calories I was losing.
One thing that I'm confused about is that when we work out vigorously doesn't that suck up the nutrients and puts a lot of stress on our body? Therefore, don't we need to take in more nutrients to help replenish our body?
