Keto Weight Loss: Why Aren't The Pounds Dropping?

The ketogenic, or keto, diet is a low-carb, high-fat, and moderate-protein diet that has gained popularity for its ability to induce weight loss. While the keto diet can be effective for some, it is not a guarantee that everyone will see results. Here are some reasons why you might not be losing weight on a keto diet:

1. Not Achieving Ketosis: Ketosis is a metabolic state where the body uses ketones, derived from fat breakdown, as its primary fuel source instead of glucose. To achieve ketosis, one must drastically reduce their carbohydrate intake, typically to 20-50 grams per day.

2. Eating Too Many Calories: Even on a keto diet, it is possible to consume more calories than you burn. This can lead to weight gain or prevent weight loss.

3. Poor Diet Quality: The keto diet should consist of nutritious, whole foods. Relying on processed, non-nutritious foods can slow weight loss and introduce inflammatory compounds to the body.

4. Hormonal Imbalance: Underlying hormonal issues, such as PCOS, diabetes, or hypothyroidism, can affect metabolism and make weight loss more challenging.

5. Lack of Other Lifestyle Changes: Factors like insufficient sleep, unmanaged stress, physical inactivity, alcohol consumption, and smoking can hinder weight loss, even while following a keto diet.

6. Snacking and Constant Eating: Snacking too often between meals can disrupt the metabolic process that produces ketones and burns fat.

7. Eating Too Much Protein: On a keto diet, most calories should come from fat. If protein makes up more than 35% of your diet, it can disrupt ketosis as excess protein can be converted into sugar.

Eating too many carbs

It can be challenging to cut out carbs, especially when adjusting to the keto diet for the first time. However, it is crucial to decrease carb intake to the recommended range to reach and maintain ketosis. To help reach your intake goals, consider tracking your macronutrients using an app or calculator. This will help you determine how many servings of carbs you can have per day based on your calorie needs.

On the keto diet, some acceptable carbs include nuts and dairy, which are high-fat and nutrient-dense foods. However, eating too many of these foods can prevent you from achieving and maintaining ketosis. Sugar alcohols, such as maltitol, can also affect blood sugar levels and potentially prevent ketosis. Therefore, it is important to be mindful of your consumption of these acceptable carbs and track your intake to ensure you stay within the recommended range.

Additionally, it is worth noting that not all fats are created equal. While the keto diet includes high-fat foods, it is important to choose healthier sources of fat, such as olive oil, avocados, and nuts. These foods provide essential nutrients and can help promote weight loss when consumed in moderation as part of a balanced keto diet.

Consuming too many calories

Even when following a keto diet, it is still possible to overeat and thus not lose weight. This is because, on a keto diet, most of the calories consumed come from fat, and fat has 9 calories per gram, whereas carbohydrates and protein only have 4 calories per gram. Therefore, eating significantly more fat than you are used to can result in an excess of calories.

To lose weight, you need to eat fewer calories than you burn, creating a continuous negative energy balance. This is known as a calorie deficit. You can track your calorie intake by using fitness trackers to ensure your overall consumption is within the ideal range for weight loss.

It is important to note that the keto diet is not the only way to lose weight, and there are other dietary approaches that can be more balanced and sustainable in the long term.

Eating too much protein

Protein is a building block of life and a necessary component of any diet. It is crucial for healthy brain function, skin, bone and muscle health, building muscle mass, and recovering after workouts. However, some people on the keto diet worry about eating too much protein and reducing their ketones.

Gluconeogenesis

The idea that too much protein can kick you out of ketosis stems from the process of gluconeogenesis. This is when your body makes glucose from non-carbohydrate sources, such as protein. The fear is that if your body can use protein to make glucose, then eating too much protein will increase your glucose levels and reduce ketosis.

However, gluconeogenesis is a necessary process that happens regardless of your protein intake because certain tissues in your body rely exclusively on glucose. These include red blood cells, the renal medulla (the innermost part of your kidney), and your testes. So, when you are not consuming carbs that are easily converted to glucose, your body uses this method to produce the glucose that these tissues need.

Insulin

Alanine

Research also suggests that the amino acid alanine may be antiketogenic, meaning it suppresses ketone production.

Insulin Deficiency

Those with insulin deficiency, such as diabetics, may be kicked out of ketosis by eating too much protein. The more insulin-sensitive you are, the less likely your insulin is to increase after eating a protein-rich meal.

The best way to find your ideal protein intake is to test your personal tolerance. You can do this by calculating your keto macros manually or using a keto calculator. Then, gradually increase your protein intake and check your ketone levels. Did they drop below 0.5 mmol/L? If so, then this is above your upper limit for remaining in ketosis.

A common recommendation for losing weight or gaining muscle is to aim for between 0.73 and 1 gram of protein per pound of body weight. Individuals who are highly active, heavy exercisers, lifting weights, at an advanced age, or recovering from an illness or injury will benefit from a higher protein intake.

Not exercising enough

Exercise is an important part of staying healthy and managing your weight. It stimulates the body's metabolism and burns calories. Exercise may be especially important if you're on a keto diet, as the high-fat foods you eat are calorically dense. Burning calories through exercise can help you reach your desired weight.

To lose weight, you need to create a calorie deficit, which can be achieved by reducing your calorie intake, increasing your physical activity, or both. If you switch to a keto diet and don't watch your calorie intake, you're unlikely to lose weight.

If you're new to working out, creating a workout schedule and sticking to it is the best way to bolster a healthy exercise habit. Set a goal of three to four days a week and choose a time that's most convenient for your schedule. Keep yourself motivated by preparing your gym bag in advance or laying out your exercise clothes before bed.

Low-intensity, steady-state exercises like jogging, cycling, yoga, and rowing are least affected by the keto diet, so consider incorporating them into your workout routine.

Poor diet quality

A diet that is high in processed, non-nutritious foods can slow down weight loss as the body is not getting the vitamins and minerals it needs to function optimally. This can lead to a slower metabolism, which is crucial for burning fat and losing weight.

To support weight loss on the keto diet, it is recommended to choose healthy fats like avocados, nuts, seeds, and oils, along with lean protein sources like seafood and poultry. It is also important to include non-starchy vegetables like leafy greens, peppers, and squash to ensure adequate antioxidant intake.

The keto diet is also notoriously low in fiber due to the elimination of fruits and whole grains. Fiber is crucial for proper digestion and the absorption of nutrients. Therefore, a lack of fiber in the diet can further contribute to poor diet quality and impact weight loss negatively.
