Suggest Diet Plan Free From Sugar And Carb

Hello, I have been instructed to eat only sugar free and carb free foods. I need to know what fruits would be acceptable. I love pineapple and straw berries but not sure if I can have that. I am using a juicer for vegies etc but not sure on the fruits. Can you help? I assume lean beef, chicken and cod are good foods to eat, right? Thx Please delete this question. I found the information I need on a web site.
