I started doing some bodyweight exercises, and have noticed my strength increasing quite a bit (newbie gains). Before wfpb, I would do literally hours of cardio each day to try to maintain my weight while eating all of the fatty stuff I used to enjoy. But that wasn't sustainable, and I'd eventually stop hitting the treadmill each day, then stop going to the gym at all, and my weight would bounce right back. I had previously focused on cardio so much because it was the best for burning calories, while resistance training doesn't burn nearly as many, but now I feel like I can incorporate a lot more resistance training and it's not a burden on my schedule.
I feel fantastic, have much better mental clarity, don't get drowsy at work at 2pm. My resting heart rate is much lower. It's pretty surreal how much of a difference it has made in such a short time.
i'd imagine that the oil could be completely omitted and the result would still be great, especially so if you subbed the heavy cream for coconut cream instead of soy milk (but i also often use soy milk to add creaminess to recipes and find it works great, if you are willing to reduce it a bit more).
