America has a new (old) fad diet. Have you heard of it?
The keto diet (short for ketogenic) is a high-fat, adequate-protein, low-carbohydrate diet. It is essentially the Atkins diet of the 2000s, but it dates back to the 1920s, when it was used to treat children with epilepsy.
The goal of a keto diet is to get at least 70 percent of your calories from fat, no more than 25 percent of calories from protein and only 5 to 10 percent from carbohydrates. For most people, that means restricting your carbohydrate intake to below 50 grams a day.
If you’re a breakfast taco fan like me, two tacos will put you at your daily carbohydrate limit, and don’t even think of putting potatoes in there! Half a cup of roasted potatoes will send you over the 50-gram limit. To further put that number of carbs into perspective, the following contain about 15 grams of carbohydrates: one slice of bread, 1/3 cup of rice, one cup of milk, 15 grapes, half of a large banana and a 12-ounce Bud Light (beers with higher alcohol will most certainly contain much more than 15 grams).
