In this segment, the speaker explains that elevated insulin levels associated with insulin resistance increase the likelihood of developing breast cancer, experiencing recurrence, and metastasizing. Blood‑sugar and insulin spikes—caused by foods that raise glucose quickly—are linked to higher cancer risk. Consequently, the speaker emphasizes that stabilising blood sugar and insulin is the most important preventive strategy. The practical recommendation is to structure every meal with a good source of protein, healthy fat, and plenty of fiber, which together blunt post‑meal glucose and insulin rises, thereby potentially reducing breast‑cancer risk and progression.

In terms of breast cancer, we know that when insulin is higher in the face of insulin resistance, then we are more likely to get breast cancer, we are more likely to get a recurrence, and we're more likely for that cancer to spread to other aspects of our body, to metastasize. We know that anything we do that causes spikes in our blood sugar and insulin and triggers this whole process of insulin resistance, where our body's insulin isn't working as well and we're making more and more of it, has been associated with more cancer. So anything we can to balance our blood sugar and balance our insulin is like kind of my number one. So at every meal, right, we— I know you talk about this all the time, right? You have a good source of protein, a good source of healthy fat, and lots of healthy fiber. And that just helps slow the, the rise in blood sugar and the rise in insulin. And that is probably like the number one thing we can do.
