What are the best sources of fats?

Whether or not fats are bad for weight loss depends on the quality and quantity of the fats you’re eating.


Now that you know the quantity of fats that you need, it’s important to understand where the best quality sources come from.


Processing food isn’t inherently bad but in general, the less processing a food has been through the more chance it has of sustaining its nutrient density. Nutrients which are key for helping you to feel full and keep your weight under control.


It’s also important to remember that foods are not inherently “good” or “bad”, there are just better quality foods which we should aim to eat more of and “poorer” quality foods which we should aim to eat less of when trying to lose weight.

A diet missing poor quality fats is not a healthy diet. These foods taste really good and are there to be enjoyed.


Can we live without them? Absolutely.


Do we have to? No.

If, however, you are able to make up 80% of your diet from good quality food, however, then you can get away with eating treats and still losing weight. So long as your calorie intake is low enough.


At first, this can be hard because these foods typically taste great and you will crave them.


Amazingly though, our taste is plastic (meaning our cravings can change) and responds to the foods we eat regularly.


Understanding your nutrition requirements based on your goals and individual barriers is a key part of achieving sustainable weight loss, just like our clients below.
