The amount of fat truly depends on your unique biochemistry, so will look different for everybody! Also, it's important to keep in mind that adding fats to your diet supports weight loss without an excess/surplus of carbohydrates and protein. While there really is no magic macronutrient breakdown that will work for everybody, you can consider the following as a baseline, and then adjust as needed:
Breakfast: 50 to 60% fat, 25% fiber, 25% protein
Dinner: 40- to 50% fat, 30-35% fibe,r 25% protein
Breakfast: 60 to 75% fat, 20% fiber, 5% protein
Dinner: 40 to 50% fat, 30 to 35% fiber, 5 to 15% protein
NOTE: Fiber means plant-based foods. In the morning that means non-starchy vegetables, avocado, nuts, seeds etc. and in the evening that includes fruit, starches, legumes and whole grains in addition to the non-starchy options.
