Ice cream is one of my weaknesses- especially when it is hot outside, I like to have something that is cold, sweet and creamy.
I have started buying flavored Greek yogurt to substitute. It's not the same, and still has sugar, but has much more protein less fat than your typical ice cream. And, it is close enough for me to satisfy my craving. I really like Chobani's key lime yogurt, and Dannon's Light and Fit Cheesecake ice creams.
For the past few months, I have tried not to buy ice cream from the grocery store, so I only ever get it when we go out to eat. It was hard at first, but over time, it has been getting easier.
