The ketogenic diet helps activate a metabolic pathway known as ketosis, which enables the body to use fat as energy. Glucose is our primary source of energy and takes priority over ketones, which are created through the conversion of fatty acids. Glucose is stored in the body as glycogen and is replenished through the consumption of carbohydrates.
The goal of the ketogenic diet is simple–deplete your stored glycogen so your body has no choice but to burn fat.
The restrictive nature of the keto diet helps suppress the consumption of processed, non-satiating foods such as breads and desserts. This is achieved by primarily consuming fats and proteins, which are highly satiating and inefficient at restoring glycogen.
In and of itself, the keto diet does not cause weight loss–instead it helps suppress appetite while maintaining a favorable state where stored fatty acids can roam freely from fat cells and be converted into energy.
A notable downside to the ketogenic diet is the elimination of many whole fruits and vegetables. For this reason, the ketogenic diet’s long-term viability is questionable. The diet has undoubtedly helped many achieve dramatic body transformations and success stories speak volumes as to who the diet is really for–those who have lost control of their weight and appetite and need clear and strict guidelines to follow.
Your plan after the ketogenic diet matters just as much as your decision to begin. Falling into old habits of eating junk food will quickly bring you back to where you started. Healthy eating is a lifelong endeavor, and it doesn’t end if you decide to take a break from the keto diet.
Let’s Talk Carbs
Counting carbs is absolutely critical to your success on the ketogenic diet. Always read nutrition labels and don’t take risks on foods without them. You must become an expert at detecting foods that contain sugars, starches, and grains as ingredients.
How many carbs should you consume in a day? Although you’ll find many sources suggesting that 5-10% of your daily calories, keep the number simple. 20 grams of net carbs is a limit that generalizes well to the population.
Your key performance metric is net carbs. Why “net” carbs? Because fiber is a carbohydrate that doesn’t count towards your daily limit. This enables you to add a short list of vegetables to your diet without concern for exceeding your daily limit.
