losing weight isnt rocket science, dont eat sh*t food, go to the gym and do at least 30 mins cardio 3 - 4 times a week. Do that and you'll shed pounds in no time.
Ill add fruit and vegetable purees to the cake batter,and I wont be using sugar.
To each their own but I'm just not seeing why you would want to only eat chocolate cake and brownies made out of all these ingredients. I can't imagine vegetable puree added into a cake would be good at all.
Even if normal sweets were healthy for me I couldn't possibly eat them all day.
Having a protein cake/brownie as a snack or in between meals I can definitely understand, but as your entire diet?
