This is a really good questions, because many people believe that fasting is the same as starving yourself, or withholding something (in this case, food). With intermittent fasting, it’s very common to go 18-20, sometimes 24 hours without eating. Science has even shown remarkable health benefits for fasts longer than 24 hours, too. But, this only account for the amount of time you’re eating (or not eating) – not that amount of calories you’re consuming. Let’s assume you normally consume 2,000 calories in a day, spread over 5 times of eating – which averages roughly 400 calories per feed. We’re not saying, that by eating only twice per day, you now only consume 800 calories. What we’re saying, is that you consume that same 2,000 calories but in two big meals. We have a few articles related to this concept that go into more detail, but all we’re doing here is reducing your feeding window – not reducing calories.
