I've never understood when people say pleasure factor when they refer to giving in to cravings that keep them unhealthy, overweight, and miserable. Sounds more like pain factor to me. When the pain of being overweight and out of shape gets to be too much you'll find a way to get over your issues with sweating and heaving.
To me the pain of eating cupcakes and chips is unbearable. I hate myself afterwards so I rarely indugle. Exercise is pleasure (it's actually unfreakinbelievably awesome!!) if you find a way to reframe it in your mind. And sweating is another way your body detoxes. Most people could use more sweating and more heaving too. Heaving is a great way to verbally dissipate stress which means no urges to supress it with food.
