How to get lean? The process of getting lean and how to lose fat is actually very simple. It's not easy, but getting a lean body is 100% something anyone can do. If you follow my 3-part plan on how to get lean — from my fat loss diet and fat loss training training, as well as the crucial steps I took to prevent fat regain — I guarantee you’ll get lean fast and, more importantly, maintain your ‘shredded body’ for good.

The reality is your body naturally resists getting too lean. It’s why dropping below even just to 12-15% body fat can start making you feel terrible and why most people who get that lean struggle to stay there. So if you are just starting out or don't have much dieting experience, aim for around 15-20%. And if you’re more experienced or have less fat to lose, aim for 12-15%. Those levels of leanness are still impressive and look fantastic, especially if you’ve built muscle along the way. A recent study found that a more aggressive approach early on in the diet led to better fat loss results. So, how exactly did I apply this to get lean? Well, typically, during a diet, I’d eat around 2,300 calories. This time, however, the very first week of my diet, I ate just 1,200 calories a day. Now I HIGHLY recommend against this. I did this for an article to see how much belly fat I could lose in just 1 week. But, for the next 4 weeks after that, I still went aggressive. Eating just 1,900 calories a day. Surprisingly, it was easier than expected. Until things started going downhill in the fifth week. But, because I had started with such a steep deficit in the beginning, I was able to increase my daily calories by 300 to continue slowly losing fat without ever feeling like my diet was becoming unsustainable However, regardless of whether you start out more aggressive or not when it comes to how to get lean, you’re going to have to eat fewer calories, and continue doing so for several weeks. Here’s exactly what I did to make my diet easy and enjoyable. Let’s start with the most important macronutrient. Protein. Eat enough protein every meal. As a simple guide, open your hand. The protein portion in each meal should be at least the size of your palm. But now, let’s talk about the big one when it comes to getting lean. Cutting calories. You don’t have to eliminate carbs or fats entirely. Instead, it’s about modifying how much of them you eat. Tip: here’s how I made weekends work for me: a science-backed strategy called planned hedonic deviation (a fancy term for "treat meal”).
