The answer to this question is yes and no. As We discussed in the previous blog on carbohydrates, eating too many calories, more than what you burn will make you fat. No matter what the food is.
Fats however do yield a greater calorific value of 9 kcal/gram, as opposed to the 4 kcal/gram for protein and carbs, so it is a good idea to keep consumption at a moderate level in order to avoid excessive calories.
Fats are not your enemy, they are an essential part of your diet.
They are are a great energy source and they slow down you digestion to keep you fuller for longer (important if you're on a calorie restricted diet).
They also play a role in hormone production and brain function.
So, in your quest to lose fat, what is important is that you reduce your overall calories, and yes some of those calories can come from fat, but I would never put a client on a very low fat diet, for the above reasons.
