On the contrary, good quality carbohydrates contain lots of nutrients and fiber if consumed moderately,if not exceed you will not get fat. By contrast will help you lose weight. If you regulate the amount of carbohydrates you eat but especially those who have to eat, what you get is a good to a bad, definitely.
On the other hand any malnutrition that will make you overeat fat, whether it is healthy or not. If you eat healthy carbohydrates and eat in the right amounts will benefit you in the process of weight loss and obviously not get fat.
Two Should avoid fat at all costs?
The human body needs three macronutrients to function properly. These three macronutrients are protein, carbohydrates and fats. But like the previous answer, there are fats that are harmful and there are fats that favor us. Fats you should avoid at all costs are saturated and hydrogenated, and the latter treated as poison. Instead yes you should consume unsaturated fats and monounsaturated fats are the good fats. Fat is essential for many body functions, including omega 3 helps eliminate fat and thinning so do not stop eating. Good sources of fat are olive oil, canola oil, coconut oil, seeds and nuts
