With the Keto diet being very popular right now, you may be thinking about trying it yourself. Is it the right diet for you?
Before deciding, what exactly is a keto diet? The diet is characterized by a dramatic reduction in carbohydrates and a LARGE increase in fat intake. A classic keto diet is 87% to 90% fat, with the other 10%-13% being a combination of protein and carbs. Without carbs (the body’s typical go-to fuel) the body goes into ketosis, in which the liver breaks down fat for energy. Most people try the keto diet to lose weight and/or improve blood glucose/sugar control. There is evidence that this diet works for those purposes. However the bulk of evidence for the effectiveness of the keto diet is for people who have drug resistant epilepsy.
The question becomes can you stick with a diet plan that eliminates bread, pasta, rice, beans, corn and other starchy vegetables, fruit, milk and sugar? Fats (0 carbs) should make up the bulk of your diet; recommended fats are olive oil, flaxseed oil, avocado oil, butter, coconut oil, cheese and animal fats. Note that the American Heart Association recently warned that coconut oil is loaded with saturated fat and may raise LDL/bad cholesterol. A keto diet can be followed without the use of coconut oil. Also allowed are small-moderate amounts of protein such as fish, eggs, seafood, poultry and meat. Small amounts of low-carb vegetables are allowed as well, leafy greens, broccoli, cauliflower, Brussels sprouts, cabbage, cucumber, celery, tomatoes, peppers, zucchini and herbs. While there is no calorie counting involved, carbs need to be carefully tracked to maintain the state of ketosis.
In my weight loss counseling experience, a significant decrease in a macronutrient group (carbs, fat and protein) is very difficult for most people to follow long term. And, numerous studies show that what’s most important for long-term weight loss success is adherence. Generally, for most people trying to lose weight I don’t recommend diets that are very high or low in specific macronutrient groups. There are easier more balanced approaches to weight loss. Plenty of evidence supports that having a more balanced diet plan, while decreasing calories can help you lose weight.
There are some people who prefer and can adhere to a very restrictive diet long term and for a small percentage of people the keto diet may be a good choice.
Side effects are possible following a keto diet, such as the “keto flu”- fuzzy thinking, nausea, fatigue and headaches in the first 4-5 days as your body begins to adjust to your new way of eating. People may also experience hypoglycemia/low blood sugar, dehydration, nutrient deficiencies, kidney stones and GI issues such as constipation. Vitamin and mineral supplementation is recommended. There are pre-made ketogenic specific vitamins available.
