When the female body senses it’s headed towards famine, it will increase the production of the hunger hormones, ghrelin and leptin, which signal the body that you’re hungry and need to eat (2). Additionally, if there’s not enough food for you to survive, your body is going to shut down the system that would allow you to create another human. This is the body’s natural way of protecting a potential pregnancy, even if you’re not actually pregnant or trying to conceive.
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.
How It Works: Warriors-in-training can expect to fast for about 20 hours every day and eat one large meal every night. What you eat and when you eat it within that large meal is also key to this method. The philosophy here is based on feeding the body the nutrients it needs in sync with circadian rhythms and that our species are “nocturnal eaters, inherently programmed for night eating.”
Hi Thea, That’s wonderful that IF has worked for you. Diets, and particularly fasting, can be very triggering for others with a history of an eating disorder. People who have been in remission can relapse. For more about what concerns and problems others have had, there is alot of information out there, and for starters I recommend this thorough article from Psychology Today: https://www.psychologytoday.com/us/blog/hunger-artist/201411/the-fast-diet-fast-route-disordered-eating

Every diet plan that has ever produced results is, at its heart, a strategy for lowering calorie intake. All-fat, no-fat, reduced-carbs, gluten-free, paleo… they may all take different approaches to weight loss, but they all have the same result. By limiting food intake, or even just limiting food options, these diets reduce our calorie consumption. And when calorie intake drops below calorie burn, that’s when we start to drop the pounds.
Cons: Even though there is flexibility in when you eat, Leangains has pretty specific guidelines for what to eat, especially in relation to when you’re working out. The strict nutrition plan and scheduling meals perfectly around workouts can make the program a bit tougher to adhere to. (You can learn more about the specifics — as well as when to time these meals — directly from Leangains here and here.)
One potential disadvantage of this schedule is that because you typically cut out a meal or two out of your day, it becomes more difficult to get the same number of calories in during the week. Put simply, it's tough to teach yourself to eat bigger meals on a consistent basis. The result is that many people who try this style of intermittent fasting end up losing weight. That can be a good thing or a bad thing, depending on your goals.

Now if you're not used to drinking your coffee black, don't despair. There are some no-sugar options that can help lighten and sweeten your morning cup of joe. If you're like me and can't fathom the idea of drinking black coffee, consider adding a few splashes of unsweetened almond or coconut milk. Cutting out the sugar can be especially hard for some people, but there are sugar-free substitutes on the market, such as stevia, erythritol, or xylitol, that can serve as a great alternative. Another modification you can make in your coffee during IF is to consume bulletproof coffee. Simply by adding high-quality grass-fed butter and MCT oil, you may find yourself having a much easier time abstaining from food.
No cravings. Fat doesn’t spike your blood sugar levels. In fact, a keto diet is so effective at stabilizing blood sugar that it got type II diabetics off their medication entirely, according to a recent study.[15] If you pair a keto diet with fasting, your blood sugar will stay stable and low (but not too low) all day. Say goodbye to the cravings, fatigue, and mood swings that make high-carb fasting so difficult.
Before the Nobel Prize was awarded to Yoshinori Ohsumi, other researchers were making groundbreaking discoveries about autophagy. In 2009, an article was published in Cell Metabolism entitled Autophagy Is Required to Maintain Muscle Mass. In this article, researchers described how deactivating an important autophagy gene resulted in a profound loss in muscle mass and strength.
One thing to consider about bone broth that sets it apart from plant foods: Even if you do eat a variety of plants that contain collagen-boosting nutrients, if you have a weakened digestive system, you may not fully absorb them. On the other hand, the collagen in bone broth is incredibly easy to absorb, even for those with compromised digestive systems.
Also, be aware that when you exercise, your body directly burns away glycogen (a form of glucose stored in the muscles). Fasting depletes these stores, which can mean less available energy for the muscles to use when they need it. This can lead to extreme fatigue and decreased performance. The best fasting tips for athletes are to precede each workout with a low-calorie protein shake designed to deliver creatine, BCAAs, beta-alanine, and other amino acids directly to the muscles as they work them, and then to follow each workout with a whey-protein supplement to replenish depleted nutrient stores in order to speed up the recovery process. These workout supplements won’t add much to your overall calorie count, and will help ensure that your intermittent fasting schedule and your workout regimen aren’t getting in each other’s way.
Hi Tade, there are benefits and pitfall in training in a fasted state. Though fasted training may push your workout routine to the next level, always listen to your body to make sure it’s not suffering. If you’re used to high-intensity workouts, fasted training might not be for you. For more info, you can check out this link: https://perfectketo.com/fasted-training/

There are MUCH bigger fish to fry with regards to getting healthy than a few calories here and there during a fast. 80% adherence that you stick with for a year is better than 100% adherence that you abandon after a month because it was too restrictive. If you’re trying to get to a minimum bodyfat percentage, you’ll need to be more strict – until then, however, do what allows you to stay compliant!
Surprisingly, since I've started intermittent fasting I've increased muscle mass (up 10 pounds from 205 to 215), decreased body fat (down 3% from 14% to 11%), increased explosiveness (set a personal best with a clean and jerk of 253 pounds a few months back), and decreased the amount of time I've spent training (down from 7.5 hours per week to 2.5 hours per week).
Fat loss. Keto and intermittent fasting are a one-two punch for losing weight. Fasting and keto both spontaneously increase fat loss, even when people don’t intentionally restrict their calories.[18][19] When you pair intermittent fasting and keto together, you become a fat-burning machine. The weight comes off quickly, and because keto also suppresses ghrelin, you don’t get nearly as much of the hunger and feelings of deprivation that usually accompany weight loss.
Hunger suppression. A ketogenic diet suppresses hunger, too.[16] On a keto diet, your liver turns fat into little bundles of energy called ketones, which it then sends through your bloodstream for your cells to use as fuel. Ketones suppress ghrelin, your body’s main hunger hormone.[17] High ghrelin makes you hungry. On keto, your ghrelin stays low, even when you don’t have food in your system. In other words, you can go longer without eating and you won’t get hungry. Fasting becomes significantly easier on keto so you can fast for longer windows to reap all the benefits.

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.
