The blood test looks at standard blood parameters, this includes liver function, thyroid, glucose, inflammation markers, cholesterol, red and white blood cells, etc. This can therefore provide a great tool to track progress. I often see inflammation markers reduce, glucose regulation improve, cholesterol levels lower. Note: It is not a blood test that looks at “food allergy”
I have helped numerous clients succeed in significant weight loss journeys that involve losses of over 20-30 kg in body fat over the space of 1-2 years or more. I actually find such longer term journeys more rewarding as they allow me to teach my clients about the impact of nutrition and lifestyle habits on their physiology. This not only helps them, but also helps those closest to them as well.
