Those issues can be part of what's known as the “keto flu,” Warren says. Other side effects of the keto diet, all of which are tied to carb withdrawal, can include lightheadedness, nausea, mental fog, cramps, and headaches, in addition to tiredness. Luckily, the keto flu doesn't usually last more than a week—which is coincidentally about when people start to see the number on the scale go down, says Warren.
This diet plan focuses on foods that are sources of protein and fat, which will help to keep you feeling full which may help you eat less overall. However, the keto diet is not a license to eat as much bacon and cheese as you want. It is even more critical to make good choices while on this diet because following a strict keto diet could result in vitamin and mineral deficiencies. And while the diet does eliminate many processed and ‘junk’ foods, it also limits many fruits, vegetables, and other important fiber-rich carbohydrate foods, which provide many health benefits.
The main advantage of the low-carb diet is that it causes you to want to eat less. Even without counting calories most overweight people eat far fewer calories on low carb. Sugar and starch may increase your hunger, while avoiding them may decrease your appetite to an adequate level. If your body wants to have an appropriate number of calories you don’t need to bother counting them. Thus: Calories count, but you don’t need to count them.
There is research that supports the ketogenic diet for diabetes management, while other research seems to recommend opposing dietary treatments like a plant-based diet. Research from 2017 confirms that people with diabetes who followed a plant-based diet experienced significant improvements in blood sugars and A1c, cardiovascular disease risk factors, gut bacteria that is responsible for insulin sensitivity, and inflammatory markers like c-reactive protein.
The benefits above are the most common ones. But there are others that are potentially even more surprising and – at least for some people – life changing. Did you know that a keto diet can help treat high blood pressure, may result in less acne, may help control migraine, might help with certain mental health issues and could have a few other potential benefits?
