Intermittent fasting is a diet that has helped many people lose weight and maintain overall health. There are many variations of the fasting diet, but the 18/6 intermittent fasting seems to have a fan following among all. It involves skipping meals for 18 hours and then eating only during a 6-hour window.
What is 18/6 Intermittent Fasting?
18/6 is a fasting plan gives an eating window of 6 hours, and you fast for 18 hours at a stretch in a day. There is no restriction on what you should eat in the eating window, as long as you are consuming it in the eating window.
18/6 Intermittent fasting means 6 hours feeding and 18 hours fasting in a given day
You can execute an 18-hour fast schedule every day or a couple of times per week. It’s entirely up to you how often you want to repeat this cycle.
It’s easy to implement 18/6 fasting because it doesn’t require you to adjust your eating habits. It allows you to fast in a more flexible way than other fasting or diet regimes.
Sometimes this is referred to as 18:6 Fasting and even “.18/.6” Fasting as well, fyi.
How to Follow 18/6 Intermittent Fasting?
It depends on the time of day you are most comfortable not eating. Some people cannot skip the morning breakfast, so they choose the 6-hour eating slot that includes breakfast and lunch.
Others who wake up late or prefer their dinner can just have lunch and dinner. Depending on your comfort, you can set your 18/6 intermittent fasting meal plan.
So, there isn’t a hard and fast rule on when you should or should not eat. You can customize the plan according to what works best for you. Even though an 18-hour fast in a day might sound crude, it is not that tough to follow since most of the fasting window is covered in the sleeping time.
So, It is better to add a good sleep of seven hours to your routine to avoid hunger cravings. Also, you should try eating foods that make you feel fuller and not bloated. Foods like fresh fruits, fiber-rich veggies, curd, buttermilk, low-fat milk, fish, and lean meat are believed to help avoid bloating.
18/6 Healthy Fat Foods

It is important to pay attention to what you eat during eating time, and what is your eating pattern. You should have a diet rich in essential vitamins and minerals. Eating protein, legumes, fruits, vegetables, olive oil, dairy, etc., which are rich in healthy fats, minerals, fiber, complex carbohydrates, and vitamins, is important to maintain a balanced diet.
You can have water, unsweetened and milk-free coffee or tea, or water even during fasting. Some people who aren’t strict in fasting also have low-calorie food items or beverages such as coffee creamers and artificial sweeteners. However, these can induce hunger and make fasting tougher.

Controls Diabetes

The fasting window stops glucose production as there is no food in the body. Also, the pancreas does not need to produce more insulin to make the glucose reach the body cells, which is the primary reason behind insulin resistance. Thus, diabetes is automatically controlled while following an intermittent fasting regime.Also helps balance blood sugar levels and Insulin levels.
Aids Cognition and Cerebrovascular System
Intermittent fasting is known to have effects on the brain and cognitive functions. It induces cellular adaptations in neurons, by increasing stress resistance, neurogenesis, and synaptic plasticity. Still, more research is needed to recommend intermittent fasting for cerebrovascular issues in regular clinical practice.
Prevents Cardio-metabolic Disease

Pushes Metabolic Activity
Due to the longer fasting time, the body might go into a state of ketosis. The released ketones will shift the body’s energy requirements from glucose, from the food we consume to stored fat cells. It automatically boosts metabolism and further strengthens the immune system.
However, the excess of ketones in diabetic patients can be fatal as these can lead to diabetic ketoacidosis (DKA). So, people with diabetes are strictly advised to follow intermittent fasting under their doctor’s observation.
Cons of Intermittent Fasting schedule 18/6
Weakness and fatigue
Due to a restricted eating duration, some people might not be able to complete their nutrition requirements and end up feeling tired all the time.
These symptoms might occur in the initial phases of fasting and might reduce after the person gets into a routine.
Bloating (temporary)
If you try to binge eat during your 6-hour eating period, your digestion might get haywire. Some people experience bloating due to over-eating. Some people may eat more in the eating window due to time restrictions and end up bloated or gaining weight.
Constant hunger
Hunger during 18:6 Intermittent Fasting
While some people report improved digestion and feeling less hungry with intermittent fasting, some practitioners observed the reverse. They felt constant hunger and it was challenging to sustain the fast.
Difficulty in coordinating medication
It might be difficult to coordinate medications that cannot be taken on an empty stomach. Consulting a doctor is crucial before taking on a strict fasting plan such as 18/6.
Affects reproductive health
Some animal studies and human studies show intermittent fasting negatively affects the reproductive system due to poor nutrition, however this data is flawed. The highlighting effects of the study were loss of body weight, blood glucose, menstrual cyclicity, and estradiol hormone. Therefore it’s especially important to pay attention to what you are eating while doing fasting. If you eat a healthy diet full of nutritious foods and fulfill your protein and calorie needs, your reproductive health will not be altered, so this is actually false in reality.
Insufficient nutrition
You might have to struggle with insufficient vitamins and minerals in your body due to the limited eating time. You can try to cover this by eating healthy foods to the best possible to meet this nutrient gap.
Conclusion
I personally love 18/6 fasting, its a nice long range where you get amazing autophagy and benefits, more so than 14/10 or 16/8. I will start my feeding at 11am usually, then end at around 5pm with my last meal. But if you feel it is too long, don’t worry! 14 or 16 hours is also beneficial. Again with fasting, the longer you can sustain it the better it can be, within reason of course.
