I’m fasting for three days a week for the whole of this month. It’s not for everyone, I know, and it’s important to talk to your doctor first, but the benefits are well researched and include improved digestion and immune function, and lowered blood pressure. When we fast, the body goes into ketosis, which breaks down fat for energy, and to stay in ketosis afterwards it helps to reduce carbs and increase protein, which is where today’s low-carb, zero-waste recipe comes in.
