At Mountain Trek, we hear a lot of guests say they’re “intermittent fasting.” To some, this means skipping breakfast; to others, this means eating just dinner. Which is right? Which is wrong? Mountain Trek also practices intermittent fasting (IF) and has developed a specific method over the past 20 years proven to help guests ignite their metabolism. Here, our Registered Holistic Nutritionist, Jenn Keirstead, gives us the scoop on Mountain Trek’s approach to IF:
What is Intermittent Fasting?
Intermittent Fasting has become the latest health fad that allegedly assists with weight loss. It has even ranked as the “trendiest” weight loss search of 2019. The dietary term is used to describe the cycle between periods of fasting and eating.
Experts say: it’s not all hype. In fact, many agree that the diet can be helpful in boosting longevity, maintaining blood sugar levels, and reaching a healthy weight.
Not surprisingly, given the popularity, several different types or methods of IF have been established. Explained below, are a few of the most popular methods:
Time-restricted eating: Fast for 16+ hours each day
This method involves fasting every day 16+ hours and restricting your daily “eating window” to 8 hours. For example, if you finish your last meal at 8 p.m. and don’t eat until noon the next day, you’re technically fasting for 16 hours.
The 5:2 diet: Fast for 2 days per week
For one to two nonconsecutive days per week, you consume just water plus 500 calories, (200 of which are protein), either in one meal or spread out over the day. The other five or six days a week, you can eat whatever you want, whenever you want.
Alternate-day fasting: Fast every other day
For the first 24 hours, you consume just water plus 500 calories, (200 of which are protein), either in one meal or spread out over the day. For the second 24 hours, you can eat whatever you want, whenever you want. Repeat the cycle every two days.
After reading about a trend, I always like to ask myself: is this diet restrictive in any way, and is it sustainable long term? These are always good points to ponder before you find yourself in yet another diet + binge cycle.
Also, a word of caution from Dr. Frank Hu, chair of the department of nutrition at the Harvard School of Public Health. Hu explains: “It’s human nature for people to want to reward themselves after doing very hard work, such as exercise or fasting for a long period of time; so there is a danger of indulging in unhealthy dietary habits on non-fasting days. In addition, there’s a strong biological push to overeat following fasting periods. Your appetite hormones and hunger center in your brain go into overdrive when you are deprived of food. He also comments, “Part of the fascination with IF arises from research with animals showing that fasting may reduce cancer risk and slow aging. One hypothesis is that fasting can activate cellular mechanisms that help boost immune function and reduce inflammation associated with chronic disease.”
How to do Intermittent Fasting correctly
Here at Mountain Trek, we too have our opinions about the structured fasting and eating cycles. Program Director, Kirkland Shave, describes our version as a, “12 on, 12 off.” He explains how, “The Mountain Trek program, where we take a 12-hour break without food (glucose) at night, aids in deeper sleep, less calorie storage, less LDL cholesterol production, and lowering the potential for Insulin Resistance (precursor to type 2 diabetes).” We also believe that fasting is beneficial in supporting the anti-inflammatory response of cellular autophagy (self-eating). According to Priya Khorana, PhD, in nutrition education from Columbia University, this is the body’s way of, “Cleaning out damaged cells, in order to regenerate newer, healthier cells.” Autophagy occurs when sleeping—another reason to fast at night.
The idea of eating during the day makes sense to us. This is because you’re eating when your body and brain are most active. This way you consume your calories when your body needs them the most. You are literally fueling your metabolic engine as it needs energy, rather than operating on a full tank all the time. When done correctly, with proper portions and timing, this means your engine will be running as clean and efficient as possible. No build-up, no excess.
We support a daily 12-hour fast, for our reasons above—we’ve just restructured the guidelines, to encourage a more healthful, sustainable, and practical approach.
Break your fast first thing in the morning
Let’s begin by “breaking the fast.” Once you’re up and ready to roll, consider breaking your fast with food. Real food first please, not coffee! Ideally, this happens within 30 minutes of rising.
There are options here. If you’re the exercise-before-work type, you can grab a quick snack consisting of a fruit/veggie, with a protein. Some examples include: apple + seeds, carrots + nut butter, or a 5 oz smoothie made from frozen berries, spinach, banana + hemp hearts. This amount of nutrition is enough to boost your anabolic metabolism by supporting the steroids that stimulate protein synthesis, muscle growth, and insulin production.
You can also break your fast with actual breakfast. Fantastic examples include: a veggie omelette with sprouted, whole grain bread, or a bowl of oatmeal with berries and seeds.
Eat every 3-4 hours for 12 hours
We suggest that you continue on throughout your day with both lunch and dinner, including 1 snack in between each meal. This means you’re eating every 3 – 4 hours during the waking hours, which will continue to support blood sugar levels, leaving you more satiated and energized.
If you intend to adhere to the 12 hour fasting window, dinner is required to be an earlier meal. This may take the most planning. To enjoy dinner at a more reasonable hour, you may want to try batch cooking on the weekends, a crock-pot meal, or one of the many convenient, health-supporting Apps, in which you can pre-order food right to your door. Do whatever it takes to make having an earlier dinner easier!
Fast for 12 hours overnight
That brings you to your “12 hour nighttime break without food.” This might feel challenging at first, as many of us are accustomed to late-night eating and snacking. Many people find themselves mindlessly eating late at night, even when they aren’t hungry.
Something to consider is that nighttime eating may be the result of an overly restricted daytime food intake, leading to ravenous hunger at night. You may find that more consistent eating throughout the day helps curb the out-of-control feeling around food in the evening—ideally you will leave at least 3-4 hours to digest before going to sleep. Speaking of sleep you may notice your sleep improves, as you’ll get to truly rest, instead of digest. Learn more about our sleep program.
Another bonus of IF and eating dinner earlier: after 12 hours food-free, you’re actually hungry when you wake up! This helps make the breaking-the-fast upon rising a breeze.
