On a Keto diet, you consume 55 to 75 percent of your calories from fat, 15 to 35 percent from protein, and less than 10 percent from carbohydrates. Because of this, carbs are arguably the most optional macro. These aren’t functions you want to miss out on.Ĭarbs provide a vital form of energy called glucose, but in the absence of carbs (such as Keto or fasting situations), your body can make its own glucose via gluconeogenesis. They’re both “preferred” energy sources.īesides providing energy, dietary fat also helps you build cell membranes and absorb fat-soluble vitamins like A, D, E and K. Amino acids (the building blocks of protein) are needed to build muscle, synthesize hormones, heal wounds, promote neurological function, and much more.īut protein isn’t so great for making ATP, and that’s where carbs and fats come in. Of all the macros, you could argue that protein is the most critical. Micronutrients, predictably enough, are required in micro amounts. Why are they called macros? Because carbs, protein, and fat are required in large (or “macro” amounts) to keep your body humming. (In case you were wondering, alcohol has 7 calories per gram).The different macros have different caloric densities. But unless you count social lubrication, it has no important functions. ![]() In your body, calories are converted to usable energy as ATP, which in turn powers all your cells. The three primary macronutrients-carbohydrates, protein, and fat-provide the calories needed to fuel your body.Ĭalories, by the way, are a form of stored energy. There’s more confusion, however, when calibrating fat and protein macros. Missing the mark here will generally (though not always) derail your Keto diet. Most people know that keeping carbs low is the number one rule of Keto. What happens if you go over your Keto macros? That depends on the macronutrient. The basic idea is to keep fat high, protein moderate, and carbs low to enter the fat-burning state called ketosis. These are the big ones, but they're definitely not the only ones.If you’ve tried the Keto diet, you’re probably familiar with counting macros. A few include sucrose, fructose, corn syrup, lactose, barley malt, dextrose, rice syrup, maltose, agave, molasses, cane juice, fruit juice, honey, and malt syrup. When you buy something, see how many carbohydrates are listed in the nutrition facts, but just as importantly, look at the ingredient list to see if you can see any different names for sugars. It's what drives their profits! So, you need to be your own best advocate and become an expert at reading food labels. When only 5 percent of your calories are coming from carbohydrates, there's no room for error! That means you have to watch out for the hidden sugars that are in processed foods.įood companies have become professionals at hiding carbohydrates in foods. Stick with it, follow the diet to the letter, and give this plan a fighting chance before you bail. Some headaches and fatigue may be inevitable along the way. Other people need months. That means following strict macros with no cheating-no beer, no crackers, no sugar. Most people need 3-4 weeks of strict ketogenic dieting to reach peak fat-burning adaptation. Now you're asking your body to completely switch metabolisms and start using fat for energy instead of carbs.Īs Parker Hyde pointed out in the article, " Ketogenic Diet: Your Complete Meal Plan and Supplement Guide," becoming fat-adapted is a process of weeks, not just days. Getting Impatient with Adaptationīefore you jump into keto, you have to understand something: You've been running on carbohydrates your entire life. ![]() Here are the five keto mistakes you need to avoid to prevent the most prominent side effects of the ketogenic diet, like headaches, dizziness, fatigue, constipation, and nausea. And surprisingly, the culprit isn't always just "eating too many carbs." ![]() The truth is that keto is like any other diet: It can safely be done right, but it can also be done dead wrong.
