Makes me lol when idiots talk about how bad bananas, carrots, apples and potatoes are. Read on facebook yesterday the comment that fruit is just sugar on a stick.
Makes me wonder what the mental state of the person who wrote that is...
Some peeps on this forum are eating to gain muscle and strength while others are eating to lose fat while others are eating to improve athletic performance. Each of these groups of people will have different calorie goals, and macros breakdowns to achieve their goals.
So work out their diet goals then eat foods that help you get to your goals. As long as the majority of your food choices are healthy a bit of junk every now and then isn't going to make any difference.
