Is Keto Right for You?

The ketogenic diet is a high-fat diet with severely restricted carbohydrate intake (less than 50g per day!). That means breads, grains, and even fruits and vegetables are off the table - a big shift in most people’s lifestyles, and a whole lot of sacrifice. Restrictive diets like keto can often lead to yo-yo dieting or weight cycling, which is associated with many health risks.

The traditional keto diet is restrictive and often results in common side effects such as:

Keto Flu

(headaches, upset stomach, fatigue, and/or dizzy spells)


since you are cutting back on a lot of high-fiber grains, fruits and vegetables

Vitamin and mineral deficiencies

since you are removing entire food groups

The Answer: The best eating plan for you is the one that you can sustain.

Why cut carbs?

Cutting carbohydrates naturally tends to lead to weight loss, because carbohydrates cause blood sugar to rise, resulting in insulin production. Higher insulin levels equate to more fat storage, leading to weight gain. By eating a lower carb diet, less insulin is produced, and therefore, less fat is stored.

But, how low should you go?

As a science driven program, the bistroMD team looks to research to determine what works for various health conditions, genders, ages and other factors. In fact, research shows that moderate carb diets are just as effective as ultra low carb diets, such as the ketogenic diet, while being more sustainable without all the struggle and sacrifice. Keep in mind, for those with diabetes, are pregnant, heavily active, or for members with chronic diseases and on medications, we recommend always discussing with your doctor first before making any extreme dietary changes.

See the Research

In a randomized clinical trial, researchers found that a group of women who followed a moderate carb diet of 15-25% carbs reduced body fat and waist circumference over 12 weeks similarly to another group of women who followed a ketogenic diet of 5% carbs. However, to no surprise the women who followed the moderate carb diet found it easier to stick to!2

In a 6 month study with type 2 diabetics, researchers found that a 20% carbohydrate diet resulted in a decrease in A1C after 3 months and maintained after 6 months. They also decreased weight, waist circumference, and total fat mass. The study concluded that reducing carb intake to 10-25% appears to be an effective and safe nutritional approach with respect to cardiovascular risk fats and hypoglycemia.3
