Intermittent Fasting: How to Best Use it for Fat Loss (5 Things You Need to Know)

Intermittent Fasting: How to Best Use it for Fat Loss (5 Things You Need to Know)

At first glance, intermittent fasting for weight loss (and more importantly “fat loss”) seems pretty counter intuitive. The idea of skipping breakfast, consuming zero calories for several hours on end and then feasting within a designated time period goes against much of what’s typically believed to be optimal for fat loss and muscle retention. However, the truth is, intermittent fasting comes with several benefits that makes losing weight much easier to do. And when done properly, intermittent fasting can be a great tool to help you lose fat faster and for good – all without sacrificing tons of muscle mass in the process. In this video I’ll not only go through the various intermittent fasting benefits, but I’ll show you exactly how to do intermittent fasting to see the best results. We’ll cover how to begin fasting, the types of meals you should be eating, what an intermittent fasting diet looks like, whether you should train fasted or not, and so on. Give it a watch for the ultimate intermittent fasting guide! Cheers!

at first glance intermittent fasting seems pretty counterintuitive when it comes to improving body composition the idea of skipping breakfast consuming zero calories for several hours on end and then feasting within a designated time period goes against much of what's typically believed to be optimal for fat loss and muscle retention however the truth is when done properly intermittent fasting can be a great tool to help you lose fat faster and for good all without sacrificing tons of muscle mass in the process and in this video i'll show you exactly how to do so by taking a look at the following points but before we get into that it's important that you first understand that intermittent fasting is by no means anything magical when it comes to fat loss in fact the largest systematic review covering 40 studies on the topic found that when calories are equated although intermittent fasting may provide various physiological and psychological health benefits it does not provide any direct benefit for increased fat loss or muscle gain when compared to traditional dieting simply meaning that at the end of the day the calorie deficit is what ultimately produces fat loss when fasting rather than the act of fasting itself however the great thing about fasting and why i personally implement it for fat loss and recommend that you at least try it is that it makes sticking to your calorie deficit much easier to do not only does research show that it suppresses your appetite better than traditional dieting but by ingesting all of your calories within a shorter time period you're able to incorporate larger more satisfying meals that help you stay full despite being in a calorie deficit therefore likely leading to better adherence and more fat loss for you in the long run so with that being said let's start with how long you should fast for although there's several different types of fasting if your main goal is to draw body fat while minimizing muscle loss i'd recommend sticking to the 16 8 protocol popularized by martin burkhand this simply involves fasting for 16 hours and then eating within an 8 hour feeding window for example only eating between 12 to 8 pm and fasting outside of these hours it's as simple as skipping breakfast but if you struggle with this you can gradually build up to 16 hours of fasting over time and or gradually increase the number of days you fast for per week the time of day of your fasting and feeding windows are of little significance the key though is to be consistent with when they take place because it's emphasized in this 2009 paper on circadian rhythms this will best enable your body to adapt by suppressing your hunger hormone during the time of your fast it does often take around two to three weeks for your body to adapt but trust me it will become much easier over time also worth noting is that at least in rats research shows that females may have slightly more adverse reactions to fasting than men meaning that it's a good idea for females to start with a 14 10 protocol for example and then build up to the 16-8 over time when you feel you're ready now as for what exactly to consume during your fasting and feeding windows it's actually quite simple during the fasting period you don't ingest any calories or anything that spikes your insulin i would however suggest drinking a lot of water as well as black coffee green tea and or sparkling water while staying busy in order to help suppress your appetite during this time as for calorie-free natural and artificial sweeteners a 2010 literature review found that most calorie-free sweeteners don't have an appreciable effect on insulin and are therefore fine to have during your fasting period if you enjoy in your coffee or tea for example as for your feeding window the actual foods you should be eating are no different than the foods you should be eating with any fat loss diet a good rule of thumb is to stick to eighty percent of your foods coming from whole unprocessed sources with the remaining twenty percent being foods considered not as healthy so to speak a good example of this with various meal ideas is my science-based diet for fat loss video which i'll link in the description box down below now for exactly how much to eat during your feeding window as i mentioned before there's no strong evidence that intermittent fasting will help you lose fat without also being in a calorie deficit therefore i'd suggest taking the advice from this 2014 paper by eric helms and colleagues and simply multiplying your body weight in pounds by 13. this will provide you with roughly the amount of calories you need to ingest daily in order to be in a calorie deficit such that you're able to lose around a pound a week and in addition to this your protein intake will also be vital to maintain your muscle mass as you lean down so amunet intake roughly 0.73 to 1 gram of protein per pound of body weight would be ideal and in agreement with the literature so for example a pound individual utilizing intermittent fasting should place a priority on hitting these two main goals during their feeding window as for the optimal number of meals to eat during your feeding window i think the best and most convenient option is to stick with three protein rich meals this not only enables you to have larger more satisfying meals as your dieting but is shown in this 2010 paper by lady and colleagues that compared ingesting three large meals versus six smaller meals throughout the day three meals seems to be the better option for hunger control although this will likely vary individually in addition contrary to popular belief as shown in this paper from the journal of nutrition when compared to eating more frequently a lower meal frequency doesn't cause a reduction in your metabolism as it's your total calorie content and composition of your meals that governs this rather than the actual frequency at which you eat do note however that research indicates that there may be a slight advantage to spacing out protein over four meals rather than three in terms of maximizing protein synthesis meaning that if your main goal is instead to build muscle fasting may actually be sub-optimal for this reason but this is likely of little significance if you're still consuming adequate protein with your three meals which is the more crucial factor regardless though experiment with it and stick to a meal frequency that best suits your lifestyle now as for when to train although there are various potential benefits to facet training and various benefits to training in a fed state the best option for you will ultimately depend on your schedule and also what enables you to perform the best in your workout but in either case there are a few things to keep in mind in the event that you have to wait train fasted in the morning as shown in this 2014 paper from helms and colleagues this is where the timing of your post-workout meal becomes of greater importance in order to minimize any potential muscle breakdown meaning that you want to time your first meal such that you're able to ingest it shortly after your workout and it should ideally be rich in protein and carbs but if you're unable to do this based on your schedule and feeding window a good alternative is to simply ingest essential amino acids during your workout and or a whey protein shake afterwards although this will technically spike your insulin and break your fast you still get the benefit of pushing your calories later on in the day which is ultimately what makes fasting such a powerful tool for fat loss whereas in the event that you train within your feeding window for example after work you'd want to time it such that you're able to get in a meal or two with adequate protein and carbs before your workout and have a meal sometime post-workout as well although the timing now is not as important as it was with fasted training but again experiment with it and see what works best for you and what you'll be most consistent with so to conclude the video here are the main points just again keep in mind that fasting is nothing magical in terms of fat loss but for many it does make sticking to a calorie deficit that much easier to do which is why it can be such a powerful tool for fat loss
