The ketogenic (keto) diet has surged in popularity as a dietary approach for weight loss. The before and after photos floating around social media may have piqued your interest. Here's what you need to know about the keto diet and what kind of results you can realistically expect in two weeks.
What is the Keto Diet?
The keto diet is a high-fat, low-carb dietary approach. It requires a significant shift in macronutrient intake, typically consisting of:
- Fat: 55% to 60% of daily calories
- Protein: 30% to 35% of daily calories
- Carbs: 5% to 10% of daily calories
For someone consuming a 2,000-calorie diet, this translates to a mere 25 to 50 grams of carbohydrates per day.
How Does Keto Work?
Normally, the body uses glucose derived from carbohydrates as its primary energy source. These carbs are stored in the muscles and liver as glycogen. When carbohydrate intake is drastically limited, the body depletes these glycogen stores, usually within a few days.
Following this depletion, the body enters a metabolic state called ketosis. During ketosis, the body begins to break down dietary and stored fat into ketone bodies, which then serve as the primary fuel source. This shift from using glucose to ketones is referred to as metabolic switching.

Initial Weight Loss: Water Weight
Many people experience rapid weight loss when they first start the keto diet. Some research suggests that people may lose up to 10 pounds in 2 weeks or less after starting the keto diet, while anecdotal reports suggest that it’s possible to lose even more. However, this initial weight loss is primarily due to water loss, not fat loss.
Glycogen, when stored in the body, binds to water at a ratio of approximately 3 grams of water per 1 gram of glycogen. As the body burns through its glycogen stores on a low-carb diet, this bound water is released and excreted through urine and sweat. This explains why people often experience increased urination and thirst when starting keto.
Long-Term Weight Loss: Fat Loss
Once the body enters ketosis, it starts utilizing stored fat for energy. The rate of fat loss depends primarily on maintaining a calorie deficit, where you burn more calories than you consume. A safe and sustainable rate of weight loss is generally considered to be between 1 to 2 pounds per week.
