Is it bad to take in too many healthy fats if I am trying to lose weight?

Too much of anything can be bad for you. Try to keep your fat intake around 50g a day.

Yes, it can be. Too much of anything is bad for a weight loss plan. Weight loss depends on creating an energy deficit. In order to lose weight you must burn more calories than you consume. Healthy fats are also known as unsaturated fatty acids. We see these on nutrient labels as poly- and mono-unsaturated fatty acids and find them in nuts, safflower oil, an flaxseed. These compounds help to increase our HDL, or healthy cholesterol, which works to carry plaque away from the arteries. However, too many of these types of fat will likely result in an energy (calorie) surplus in the body which will lead to the weight and fat mass gain.

Weight loss comes down to calories in versus calories out.  Your diet can be high in fat as long as your total calories are less than what you are expending or using throughout the day.  Since a gram of fat is 9 calories vs. 4 calories per gram in carbohydrate or protein, the volume of food you consume may be less when eating high fat than eating a diet plentiful in lower calorie vegetables and lean protein.

However, let's not forget health! A healthy diet may allow for up to 40% fat (mostly from healthy fats) which leaves room for fruit, vegetables, beans, and lean protein.  A recent study confirmed a diet higher in naturally occuring fiber in whole grains (3 serving a day is recommended) , fruit and vegetables reduces risk of cardiovasular disease.

Yes. As with other foods, if you are eating too much fat, regardless of the kind, and are not expending a similar number of calories, you're risking weight problems and all of the related health complications. The more fat we eat, even if it is healthy, adds fat to our bodies which adds inflammation, which causes us chronic disease that decrease our enjoyment in life, and increases hospital bills.  So make sure to match your calorie intake (whether it’s from healthy fat or not) with a comparable amount of exercise.

Yes, it can be bad to take in too many healthy fats when trying to lose weight if they cause you to eat more calories than what you are burning each day. For optimal weight loss results you must ensure the amount of calories you take in through your diet are less than the amount of calories you burn through activity, and that you are taking in a balance of healthy fats, carbohydrates – consisting of fruits, vegetables, and whole-grains – and lean protein. 

Well you don't want your fat intake too high as well all need the good fat in our diet.  Bottom line as long as we burn more calories than we take in you will lose weight.  However you want to keep a healthy diet as well and not have your intake of fat too high because this can cause other health problems.
