26 Mar Is Keto Diet fad or Healthy?
What is a keto diet?
Keto diet is planned in such a way that it will be low in carbohydrate and higher in protein and fat. Due to lack of enough carbohydrates in the diet, body is forced to utilize fat as energy source by generating ketones This process is called as ketosis. Once ketosis process starts, most of the cells use ketone bodies to generate energy until there is enough carbohydrates in the diet again. This shift, from using circulating glucose to breaking down stored fat as a source of energy results in weight-loss . Ketosis is highly individualized process, and some people need a more restricted diet to start producing enough ketones than others. In addition to other adverse effects, keto diet may cause tiredness in the beginning. It may also lead to bad breath, nausea, vomiting, constipation, and sleep problems.
Is keto diet healthy?
There is an evidence showing that a keto diet reduces seizures in children, sometimes as effectively as medication. However, there are no human studies to support recommending ketosis to treat any other health conditions other than epilepsy.
Weight loss is the primary reason many people opt for the keto diet. Previous research shows good evidence of a faster weight loss when patients go on a keto or very low carbohydrate diet compared to participants on a more traditional low-fat diet, or even a Mediterranean diet. However, that difference in weight loss seems to disappear over time.
A keto diet also has been shown to improve blood sugar control for patients with type 2 diabetes, at least in the short term. There is even more controversy when we consider the effect on cholesterol levels. A few studies show some patients have increase in cholesterol levels in the beginning, only to see cholesterol fall a few months later. However, there is no long-term research analyzing its effects over time on diabetes and high cholesterol.
Key takeaways – keto diet review
A ketogenic diet could be an interesting alternative to treat epilepsy. But, even it causes faster weight-loss, it may not last for longer time. Keto diet can be heavy on red meat and other fatty, processed, and salty foods that are notoriously unhealthy. We also do not know much about its long-term effects, probably because it’s so hard to follow diet for longer time. It is also important to remember all the fad diet that causes rapid weight loss and weight gains are associated with increased mortality. Instead of going after next diet trend that you could follow only for few weeks to months (that includes a keto diet too), try to embrace change that is sustainable over the long term. A balanced, unprocessed diet, rich in very colorful fruits and vegetables, whole grains, nuts, seeds, and lots of water seems better choice for a long, healthier life.
