Kelly worked in the medical field for Fortune 500 companies like J&J, Stryker, and Hologic. She eventually moved into personalized medicine, offering tumor gene mapping and molecular subtyping to oncologists.

With her extensive background in cancer and genetics research, Kelly returned to study for a postgraduate degree in nutrition, becoming a certified functional nutritionist.

Instead, it’s about balancing macronutrients in every meal to help you feel satisfied, curb cravings, and promote optimal health. The Fab Four is a simple way to ensure that your meals contain the right balance of nutrients.

The Fab Four: Protein, Fat, Fiber, and Greens
The Fab Four is a concept that Kelly developed to help people make healthier food choices without feeling deprived or hungry. It involves including four essential macronutrients in every meal: protein, fat, fiber, and greens.

By including these essential nutrients found in her Fab Four, you can ensure that you are getting the right balance of macronutrients to support optimal health.

The Link Between Blood Sugar Regulation, Cancer Prevention, and Weight Loss

Kelly emphasizes the importance of maintaining stable blood sugar levels for overall health and well-being. She explains that when blood sugar levels spike, insulin is released, which can lead to inflammation and an increased risk of chronic diseases like cancer.

Therefore, regulating blood sugar levels is crucial for maintaining good health. One effective way to do this is by consuming a diet low in processed sugars and high in fiber-rich fruits, vegetables, and whole grains.

Additionally, engaging in regular physical activity can help improve insulin sensitivity and promote healthy blood sugar levels.

In some cases, medication may be necessary to manage blood sugar levels, but lifestyle changes should always be the first line of defense against chronic diseases related to blood sugar dysregulation.
