Severe carb limits can cause your body to break down fat into ketones for energy. This is called ketosis. Ketosis can cause side effects such as bad breath, headache, fatigue and weakness.
A person on the keto diet should limit their carb intake to up to 50 g a day. A person generally replaces high carb foods with fatty foods, such as eggs, dairy products, and fresh meat and fish. Wheat products and some fruits, vegetables, beans, and legumes can be high in carbs, so checking food labels is key.
Carbohydrate tolerance varies among individuals. Some people may need to limit themselves to no more than 30 grams of total carbohydrates per day to remain in nutritional ketosis and maintain its benefits; while others may be able to consume more.
Most ketogenic diet guidelines recommend limiting your total carbohydrate intake to 15-30 grams or 5%-10% of your total calorie intake a day. Eating more than 50 grams of carbs may disrupt ketosis. With keto diets, however, carb restrictions vary from person to person.
Even if you're trying to lose weight, your body needs enough calories and energy to function. If you're not eating enough, your metabolism could slow down because your body doesn't have the necessary energy to maintain it.
Your body may go into ketosis after just 12 hours of not eating, which many people do overnight before they "break fast" with a morning meal.
People in ketosis may experience a variety of side effects and symptoms, including headaches, stomach upset, and changes to their sleep and energy levels. For a more accurate way of determining ketosis, people can check the levels of ketones in their blood, breath, or urine.
For the human body to turn fat into ketones, it needs plenty of water, as this process doesn't just occur in the digestive tract—the body's stores of fat are also converted to ketones, providing an extra energy boost between meals. Water is an essential tool for getting the most out of your keto diet.
If potato chips are one of your favorite foods, here's a bit of unfortunate news: All forms of potatoes, including chips, are off-limits on keto.
According to a recent survey of doctors by Readers Digest, dieters shouldn't stay on the high-fat, low-carb Keto diet for longer than six months, although one local dietitian said adults shouldn't be on the diet at all.
While some people have success staying on keto for an extended period of time, “the long-term research is limited,” says Jill Gulotta, RDN, who's based in White Plains, New York. Gulotta recommends staying on keto for six months max before reintroducing more carbs to your diet.
On the keto diet, you are allowed to have no more than 50 grams of net carbs per day – and the fewer, the better!
Although caffeine doesn't stop ketosis, the bitter taste of coffee, or other caffeinated beverages like matcha lattes, causes people to add sugar to them. This will mean you stop ketosis and will contribute to your net carbs for the day.
Frequent Urination – very common
You will find yourself urinating more often as you start a keto diet. This happens because your body uses up its glycogen (stored glucose aka carbohydrates). Glycogen holds water in your body, which is why you release water by urinating.
It is entirely possible to include cheat meals on your keto diet and still lose weight. But how drastically and how often you have a keto diet cheat is certainly going to affect your progress in the long run, and you might end up undoing a lot of hard work if you aren't careful.
While it is OK to cheat once in a while on special occasions, you shouldn't cheat once a week on keto. Simply because one cheat day can kick you out of ketosis for up to 3 days. Hence, you would limit the results drastically by cheating once a week on keto.
The diet is also very restrictive that even the sugar in mouthwash and toothpaste can throw your body out of ketosis and affect your results. The bottom line is, health experts advise talking with your doctor if you want to give the ketogenic diet a try.
