What do calories from fat meando they make people fat more than regular calories

whats the difference between a calorie and a fat calorie how much fat calories is ok to eat in a day thanks for your help

In my opinion, when you see fat from calories and fat fom carbs on a bag of chips for example, it means the amount of total calories that is supplied from both fat and carbs. What you should watch out for is the percentage and the ratio; if there's a high percentage and ratio of fat calories when you compare it to the carb calories and total calories, that will be considered as a unhealthy bag of chips
