I still have some of it in my house, but over the past year I’ve cut down majorly, by refusing to snack during the day, and tracking my calories each day. Just being aware of what I ate made a huge difference. Also, instead of ice cream, I buy TruFru dark chocolate raspberries and just have a few each night. I’ve lost about 50 pounds since last January through diet and exercise.
I’m not sure any of those are full diet replacements though. They serve as a good breakfast or lunch, but I don’t think it’s recommended you replace all meals with them. At least not in more ideal circumstances.
So yeah, with a 1500 calorie deficit diet, that’s about a 3rd of what you eat for the day, so like 33%. That’s a pretty big chunk, and easily allows you to snack on occasion and still hit your deficit. I’d say it’s pretty helpful, but diet is still absolutely necessary for any results.
