Going keto to get lean and enhance workout performance is one of the hottest trends in fitness. Despite its current popularity, high fat/very low carbohydrate diets have been around for centuries and there are decades of science supporting their efficacy and safety. I’m going to show you how to put a ketogenic diet to work for you so that you can take the brakes off your body’s fat burning potential.
Ketogenic diets get their name from a group of unique compounds called ketone bodies, commonly just called ketones. Ketones are a metabolic by-product that your body creates when it is burning fat (either stored body fat or dietary fat) at very high rate. This generally only happens during long intense exercise, or when carbohydrates are severely restricted, because the presence of the hormone insulin (which is released by your body when you eat carbs) squashes fat burning and ketone production.
When you remove carbs from your diet and increase the amount of fat you are eating, your body produces so many ketones that their level in your blood increases – you are then considered to be in a ketogenic or fat-adapted state. Your body has adapted to using fat (and ketones) as primary fuel sources and not carbs/sugar.
Many people believe that this metabolic switching is the key to unlocking high performance and fat burning. However, not everyone is convinced of this. There are many diet plans that work, and ketogenic diets work very well. You just need to see if they work well for you.
One of the biggest myths about ketogenic diets is that they are bad diets if you need to perform at a high level. This is flat out untrue. I once added 80lbs to my deadlift over a 4.5 month timespan while on a ketogenic diet – no issues with performance. As your body adapts to using fat as a primary fuel source, your performance in the gym might be hindered slightly. But this is only temporary (and most of the effects can generally be overcome with a little caffeine) while your body builds the cellular machinery it needs to be a dedicated fat burning machine.
As with any diet plan, there are guidelines around how much and what types of carbohydrate, fat, and protein you can eat. Here is a breakdown of each with all the info you need to get started.
Carbs are your enemy. When on a ketogenic diet, you need to severely limit the amount of carbohydrates that you are eating to ~30g per day or less to keep insulin levels really low – allowing your body to readily access, liberate, and burn fat as its primary fuel source. If you are going to count anything on a ketogenic diet – count carbs.
Your new go to carb sources will be fibrous vegetables (and some fruit) like these:
When done right, 60-70% of the calories in your diet will come from fat (yes, that’s a lot of fat!). Your body will quickly learn to thrive on it. Your body was actually built to thrive on fat, and removing carbs from your diet frees your body from these metabolic constraints and allows you to tap into near limitless amounts of energy (via stored body fat and the fat you eat). Eat a variety of fats and try not to overdo one type. Be careful when eating nuts as they contain carbs. Walnut and Macadamia nuts are the preferred nuts, as they are low carb and high fat.
Here are some other fats to include:
