Try not to consume more than 70-80% of your daily calories from fats on a keto diet, but it’s not the end of the world if you go over one day - just make sure you get straight back on it the next day.
You should be focusing on good, healthy fats anyway - it's saturated fats that you need to steer totally clear of.
In fact, lots of people end up not eating enough fats at first, because so many diets condition us to avoid fats. Many keto newbies turn to protein first for filling power, but it’s important to get that balance right!
Remember that avocados, fish, cheese, dark chocolate and coconut oil are all keto-friendly sources of good fats.
