It’s the beginning of a new year and all you hear about is hitting the gym and starting a new diet. You think, this is it, this time it will stick, and I will lose weight and feel great. Maybe you’ll try the Paleo diet, the Keto diet, Weight Watchers, etc. Nowadays it’s pretty hard to not hear about these fad diets and how “good” they are for our health. This week we will briefly explain one of the most common diets out there right now and discuss what it means regarding your health.
The Keto Diet: If you haven’t heard anything about the keto diet you might be living under a rock. It almost feels like most people we talk to have tried going “keto” or know someone currently on the diet. What we know: the original purpose of the ketogenic diet is for the treatment and prevention of seizures in epileptic children. There are no long-term studies out there to look at the effects of the keto diet for adults on our health. Personally, I know a surgeon who was on the keto diet for six months and he ended up stopping it because of the adverse effects it had on his cardiovascular blood markers. This is just one example. The keto diet is so restrictive, and it forces the body into a state it does not want to be in. The body prefers to run off glucose and when it doesn’t get food sources of it (carbohydrates) it is forced to convert fat to glucose. Sounds good right? I mean I’m burning fat, right? With this diet, we have LIMITED carbohydrates (< 50 grams/day). If we think about the keto diet with common sense, where are we going to get our heart protective whole grains? Where are we going to get our fiber rich, cancer fighting fruits? In short, we won’t. One of the most common complaints of the keto diet is fatigue and constipation. Fatigue, because the body is in a state of ketosis (breaking down fats for fuel), and constipation because we are simply not getting enough fiber. We know that fiber is heart protective, so one can only imagine what the long-term risks of the keto diet has on our heart without enough fiber. Any time you cut out a major food group (i.e. carbohydrates from fruits and grains) it is not sustainable. So, if you’re looking to drop a few pounds by cutting out carbs, what is your long-term goal? Are you planning on doing this for the rest of your life till the day you die? If not, a restrictive diet like the keto diet is not the answer.
Unfortunately, people often want “quick fixes” well if you’re talking weight loss and a better quality of life through nutrition, you will not find a quick fix. The best thing you can do for your health is to eat a diet rich in whole foods, lean sources of protein, with plenty fruits and vegetables. Adopting this life style will lead to more energy, potential weight loss, decreased blood pressure, better control of blood sugar, and an overall increase in your well- being. So, when your buddy at the gym says, “You have to do the keto diet if you want to lose weight”, tell them thanks for their opinion, but I think I’ll stick to my whole foods and balanced plate. As always, if you ever have any nutritional concerns or questions, seek out a Registered Dietitian for evidenced based answers.
Cheers to the New Year!
