If you are looking for a simple keto recipe made with a few common ingredients, try sea bass baked with homemade pesto. Unlike fatty fish such as salmon, sea bass is naturally low in fat and high in protein. Using homemade pesto and ghee not only enhances the flavour but also adds healthy fats that make this meal suitable for a ketogenic diet.

I changed the way I ate in 2011, when I was diagnosed with Hashimoto’s, an autoimmune disease that affects the thyroid. I had no energy, and I found it more and more difficult to maintain a healthy weight.

That’s when I decided to quit sugar, grains, and processed foods, and to start following a whole-foods-based ketogenic approach to food.

Great recipe. However, there seems to be a mistake? Ingredients say 4 tablespoons but the method only refers to 2 tablespoons of pesto.

Thank you! Oh that is for each sea bass fillet so it is a total of 4 😊

Please help me this information to loss weight.. Thank you[quote][/quote]
