While these five methods are the most well-known in terms of integrating periods of fasting into your eating schedule, there are many other similar philosophies based on meal timing. For those who prefer a more fluid, less rigid method, there’s also the concept of eating intuitively. Primal Diet proponent Mark Sisson is a supporter of the Eat WHEN (When Hunger Ensues Naturally) method, where dieters simply eat whenever their bodies ask them to. However, some believe this can also lead to overeating or overconsumption of calories, since our bodies’ hunger-induced choices may be more caloric than otherwise.
Stable blood sugar levels are vital to the success of any diet. This is because when glucose levels plummet, it leads to intense hunger, which almost always results in binge eating. Stable blood sugar levels help eliminate headaches, lack of focus, poor memory, and brain fog as well. Interestingly, these are common complaints among those who follow high carbohydrate diets, as opposed to diets that are rich in fat and protein.
Fill your plate with plenty of healthy fats, such as coconut oil, avocados, olive oil, ghee and grass-fed butter as well as moderate amounts of protein foods like grass-fed meat, free-range poultry, fatty fish and eggs. Non-starchy vegetables, fresh herbs, nuts, seeds and healthy beverages like water, bone broth and green tea can all be enjoyed as well.
That said, I have heard that women may find a wider window of eating to be more favorable when doing daily intermittent fasting. While men will typically fast for 16 hours and then eat for 8 hours, women may find better results by eating for 10 hours and fasting for 14 hours. The best advice I can give anyone, not just women, is to experiment and see what works best for you. Your body will give you signals. Follow what your body responds favorably to.
The biggest concern most people have is that Intermittent Fasting will lead to lower energy, focus, and the “holy crap I am hungry” feeling during the fasting period and ruin them. People are concerned that they will spend all morning being miserable because they haven’t consumed any food, and thus will be miserable at work and ineffective at whatever task it is they are working on.
Conversely, a 2013 study completed by researchers at Washington University School of Medicine, presented the exact opposite, showing increased reactions in receptors on the tongue, when participants were given artificial sweeteners. Their study concluded that if the receptors are capable of detecting sweetness, even though calories aren’t present, a hormonal response (insulin release) is likely.
I’ll share some of my experiences, now doing heavy strength training for 3 years in a fasted state: For my first “fasted” workout or two after starting an IF protocol, it was very weird to not eat before training. However, after a few sessions, I learned that my body could certainly function (and even thrive) during my training sessions despite not eating a pre-workout meal.
Instead of going 18 hours without food, brew Bulletproof Coffee beans in the morning, and blend it with a nice big hunk of grass-fed butter and Brain Octane Oil for breakfast with no carbs or protein. If you use mold-tested Bulletproof Coffee beans, you have a satisfying, low-toxin coffee that doesn’t cause adrenal stress the way most coffee does, and it tastes like a creamy latte.

What better way to nourish your bones and joints than by consuming more of the nutrients already found within them, including hyaluronic acid, glucosamine, chondroitin, calcium, and magnesium. Bone broth contains all of these nutrients, plus several amino acids that support joint mobility and healthy inflammatory response like glycine proline. It’s for these reasons that bone broth is becoming a go-to drink among athletes.


Another program called the 5:2 Fast Diet involves eating 5 days a week and fasting for the other 2 days, when women can get no more than 500 calories and men no more than 600. That’s a quarter of the amount you likely eat on the days when you don’t fast. Whether you eat those calories in one sitting or spread them across micro-meals throughout the day is up to you.
