Why is it important to eat the recommended amount of lipids when trying to lose weight?

Can eat less: Fats are the most calorie dense of type of food: 9 calories per gram compared with 4 calories per gram of protein and 4 cal/g of carbs. So eating less fat allows you to eat more and still keep your total calorie count low which is needed to lose wt. But some fat, especially monounsaturated and polyunsaturated fat is good on a diet because it's filling and lasts longer. Balance is good.
