So, what exactly is a relaxed approach to intermittent fasting? Again, since there’s little research done on intermittent fasting, we’re dealing with a bit of a gray area. The opinions also tend to vary depending on which site you visit, or which health expert you ask. From what we’ve found, the general guidelines to brief intermittent fasting for women are:
Black coffee won't break your fast or take you out of ketosis. In fact, according to a report published in the Journal of Basic and Clinical Physiology and Pharmacology in 2017, caffeine may even increase your metabolism, which will help promote weight loss. Black coffee also helps curb your appetite, which can make getting through your morning fast much more manageable.
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.
Following what Greg lays out for us, we should wait a couple of hours and stave off our cup of jolt, kick-starter for at least a couple of hours after getting up. Instead, we should have some hydrating water. That’s a hard one, let’s be truthful. Real hard, especially for coffee lovers, but I suppose there is a reason for this. I think this has something to do with cortisol levels. This really helps when, or if you get hunger pains and then have a cup of wakey juice or two or three or four cups. This almost always alleviates the hunger, so this is why it’s so powerful.
Intermittent fasting (specifically the 5:2 diet) became popular in the UK in 2012[14][15][16] after the BBC2 television Horizon documentary Eat, Fast and Live Longer.[17] Via sales of best-selling books, it became widely practiced.[18][19] In the United States, intermittent fasting has become a trend among Silicon Valley companies.[20] According to NHS Choices as of 2012, people considering the 5:2 diet should first consult a physician, as fasting can sometimes be unsafe.[18][21] A news item in the Canadian Medical Association Journal expressed concern that promotional material for the diet showed people eating high-calorie food, such as hamburgers and chips, and that this could encourage binge eating since the implication was that "if you fast two days a week, you can devour as much junk as your gullet can swallow during the remaining five days".[22]
I was very curious about this, so I asked the opinion of metabolic expert Dr. Deborah Wexler, Director of the Massachusetts General Hospital Diabetes Center and associate professor at Harvard Medical School. Here is what she told me. “There is evidence to suggest that the circadian rhythm fasting approach, where meals are restricted to an eight to 10-hour period of the daytime, is effective,” she confirmed, though generally she recommends that people “use an eating approach that works for them and is sustainable to them.”

Diluting a small amount of apple cider vinegar in 8 ounces of water won't break your fast. In fact, it might actually be a really good idea. According to a study published in the Journal of Medicinal Food in 2018, apple cider vinegar can lead to positive metabolic changes that help promote weight loss. Drinking apple cider vinegar every day may also reduce total cholesterol, triglycerides and LDL or "bad cholesterol" levels.


Pros: While 24 hours may seem like a long time to go without food, the good news is that this program is flexible. You don’t have to go all-or-nothing at the beginning. Go as long as you can without food the first day and gradually increase fasting phase over time to help your body adjust. Pilon suggests starting the fast when you are busy, and on a day where you have no eating obligations (like a work lunch or happy hour).
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.
Reheating coffee breaks down the components, resulting in a bitter taste. With no cream or sugar to balance the flavoring, black coffee will more immediately taste bitter when reheated. If you find you must reheat your black coffee, absolutely do not use the microwave. Reheating coffee this way will break down the aromas and cause your coffee to taste stale instantly.
What and when you eat during the feeding window also depends on when you work out. On days you exercise, carbs are more important than fat. On rest days, fat intake should be higher. Protein consumption should be fairly high every day, though it will vary based on goals, gender, age, body fat and activity levels. Regardless of your specific program, whole, unprocessed foods should make up the majority of your calorie intake. However, when there isn’t time for a meal, a protein shake or meal replacement bar is acceptable (in moderation).
Intermittent fasting isn't a regimen built around limiting calories (although it's likely that your calorie intake will be restricted naturally since you're going a period of time without eating), but it can promote weight loss in a big way. Fasting gives your metabolism an overhaul. It works on the same principles as a ketogenic diet. By restricting food (and carbohydrates), you'll switch your body from burning glucose for energy to burning stored body fat.

Many people achieve the best results by starting the ketogenic diet first and then beginning intermittent fasting several weeks later. Although this is a bit different from the classic approach to the keto-intermittent fasting diet, it works better for some individuals. This is because intermittent fasting, as previously mentioned, should be a natural process, during which you should not feel deprived and hungry.


Even though you are skipping breakfast, it's still important to stay hydrated. Make sure to still drink enough water. You can also have herbal tea. The catechins in tea have been shown to enhance the benefits of fasting by helping to further decrease the hunger hormone ghrelin, so you can make it until lunch and not feel deprived. Since you’ve increased your fasting period an extra four hours, you need to make sure your first meal (at noon) has enough healthy fats. The burger in the 8-to-6 window plan will work well, and you can add more fats in with your dressing or top with an avocado!
Is intermittent fasting safe? Remember that you’re only supposed to fast for twelve to sixteen hours and not for days at a time. You’ve still got plenty of time to enjoy a satisfying and healthy diet. Of course, some older women may need to eat frequently because of metabolic disorders or the instructions on prescriptions. In that case, you should discuss your eating habits with your medical provider before making any changes.
That’s what I suggest you do when you start fasting. It should happen naturally, and you shouldn’t have to force it. If you’re still a sugar burner instead of a fat burner, it’s going to be much harder…so if you’re serious about trying out this whole fasting thing, I suggest slowly transitioning to a high-fat low-carb diet. You can read about the benefits here.
In addition, the refined sugar found in most beverages digests quickly, spiking both your blood sugar and your insulin levels. It's also highly addictive. Your body doesn't just want more, it needs more. In fact, according to a review published in Current Opinion in Clinical Nutrition and Metabolic Care in 2013, sugar and sweetened beverages and foods induce reward and craving responses in the brain that are comparable to the responses triggered by addictive drugs, which continue the cycle.

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.

I just started fasting two days ago, in order to lose weight. I ended up fasting for 16 hours, and after breaking the fast I just had a salad (approx 1000 calories) and started fasting again after 4 hours. It’s been 13 hours already and I’m not hungry at all. Is it okay if I start alternate day fasting as a beginner? As i really don’t feel dizzy at all.

How It Works: Not completely satisfied with the IF diets listed above? This method takes the best parts of Eat Stop Eat, The Warrior Diet and Leangains, and combines it all into one plan. You also get one cheat day each week (yay!) — followed by a 36-hour fast (which may be not-so-yay for some). After that, the remainder of the seven-day cycle is split up between the different fasting protocols.
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).
Alternate-day fasting. Go back and forth between feasting days and fasting days. Eat like a king or queen one day, then eat nothing the next. This will probably be the most challenging fasting option for most people. If you try it, make sure you’re eating a ton on your feast days, otherwise you’ll fall into a major calorie deficit and you’ll likely feel miserable.
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
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!
