Has Gundry ever explained why he thinks APOE4 carriers love cheese so much while doing intermittent fasting

Understanding APOE4 and Its Impact on Fat Preferences

As the founder of CFP Weight Loss and author of The Plant Paradox, I've spent years helping patients navigate genetic factors like the APOE4 gene variant. This allele, present in about 25% of the population, evolved to help our ancestors survive famines by efficiently storing and utilizing fats. Dr. Steven Gundry has explained in his lectures and books that APOE4 carriers process dietary fats differently, often showing a strong preference for saturated fats found in cheese, butter, and coconut oil. This isn't random—it's a survival mechanism that makes high-fat foods particularly satisfying for these individuals.

Gundry's Explanation: Evolutionary Cravings and Lectin Sensitivity

Dr. Gundry specifically addresses why APOE4 carriers seem to "love cheese so much" during intermittent fasting. He points out that the gene enhances LDL cholesterol transport but also heightens sensitivity to plant toxins called lectins. Cheese, being low in lectins and high in casein and conjugated linoleic acid, becomes a go-to comfort food. In fasting windows, the body of an APOE4 carrier may signal intense cravings for quick energy from fats rather than carbs, as their metabolism favors ketone production from dairy fats. Gundry notes this in his discussions on genetic polymorphisms, linking it to why many in their 40s and 50s with hormonal shifts report cheese as their "kryptonite" during time-restricted eating.

How This Affects Weight Loss in Midlife

For our typical 45-54 audience managing diabetes, blood pressure, and joint pain, this craving pattern can derail progress. Failed diets often stem from ignoring these genetic signals. In my program, we teach that APOE4 carriers may need 60-70% of calories from healthy fats during initial fasting adaptation, but sourced from lectin-free options like olive oil, avocados, and approved cheeses in moderation. This prevents the blood sugar spikes that exacerbate insulin resistance common in perimenopause. Gundry recommends breaking fasts with a small amount of full-fat cheese paired with olives to satisfy the genetic pull without triggering inflammation or overeating.

Practical Strategies to Manage Cheese Cravings

Start with a 12:12 intermittent fasting window and gradually extend while tracking cravings in a journal. Replace standard cheese with goat or sheep varieties, which are lower in problematic proteins. Incorporate my "Gundry-inspired" swaps: macadamia nuts or coconut yogurt during fasting edges. For joint pain, add omega-3s from approved fish to reduce inflammation that amplifies cravings. Most clients see a 5-8 pound loss in the first month by aligning with their genetics rather than fighting them. This approach respects insurance limitations and busy schedules—no complicated meal plans required. Understanding your APOE4 status through simple genetic testing can transform how you approach weight loss, turning what feels like failure into targeted success.
