Consuming fats allows you to fulfil your daily caloric needs with it. So consuming fats will replace the carbs you’ll no longer be eating and will help you feel full and never hungry.
So if your goal is weight loss, you don’t need massive amounts of fat, as some of it should come from your own body stores. Remember you are encouraging your body burn fat for energy and not insulin.
If you’re not hungry all the time then you don’t need to meet your fat macro, however, it’s best if you aim to meet your protein macro consistently each day for the best results..
