Depending upon which version of the KetoFLEX 12/3 meal kit you’ve selected (pescatarian or flexitarian, with or without high polyphenol olive oil) your kit will have slightly different components. 

Ten meals: Every kit will have five lunches and five dinners (that you can eat at any time during your eating window), each marked Day, 1, 2, 3, 4 & 5. It’s best to eat the meals on schedule, as they have been paired to contain the optimal daily macronutrients. Follow instructions on the back of each box; do not microwave in containers.  On Saturday and Sunday, do your best to mimic the meals you’ve eaten throughout the week. Cooking is a wonderful creative expression and can be joyful and fun.   

Extra Leafy Greens:  All kits will have extra leafy greens. Add these to your lunches or dinners as desired. Research shows that leafy greens reduce the rate of cognitive decline. 

Half-Dozen Hard-Boiled Pastured Eggs: Choline is vital for brain health and pastured eggs are an excellent source. If you’re still transitioning to two meals per day, feel free to enjoy a hard-boiled egg as a snack. If you are already adapted to two meals a day, add an egg or two to your afternoon salad for a heartier meal.

Two 8oz. bottles of high polyphenol extra virgin olive oil (EVOO): Add up to four tablespoons or more to each meal. All dressings and sauces have been specially curated to complement the taste of this quality EVOO. Research shows that high polyphenol EVOO reduces accumulation of beta-amyloid and can improve cognition. (Note: Those who’ve not opted to include EVOO should supply their own.) 

Fermented Food: This is not included in your kit but is an important part of promoting a healthy microbiome, which in turn can support brain health. Be sure to include a tablespoon or more of fermented vegetables with live active cultures every day.

The vast majority of people will experience no ill effects on KetoFLEX 12/3 and many report cognitive clarity, increased energy, and overall optimized health. However, depending upon your current state of health and genetics, there are several adverse side effects that may affect you. Fortunately, most are easy to rectify with the strategies below. 

Keto-Flu   As you switch your fuel source towards a fat-burning state, you may experience symptoms of fatigue, headache, brain fog, cramps, or light headedness. Fat-burning can lead to dehydration unless you are adequately hydrating with clean filtered water throughout the day. The vegetables and fruits that are included in the diet will supply the electrolytes you need. Feel free to season your food with high quality sea salt to support your hydration status.   

Digestive Upset   Because the KetoFLEX 12/3 nutrition plan is a significant departure from the typical Western diet, which is full of processed (pre-digested) food, that requires your digestive system to work a bit harder. The additional fiber and extra fat can both be problematic depending upon your current state of GI health. Using bitter herbs, unfiltered apple cider vinegar, organic lemon juice or peel as seasonings can be helpful. Additionally, consider digestive enzymes and acid supplementation as needed.         

Weight Loss   Some people are nervous about adding extra dietary fat, even EVOO, which can inadvertently lead to consuming too few calories. Increasing healthy fat, including high polyphenol EVOO, avocados, nuts and seeds with non-starchy vegetables can ensure adequate calories. If you find yourself losing too much weight, discontinue the long daily fast until you’ve achieved your optimal weight.
