2019 most controversial: Don’t believe the keto hype

You cannot live on steak and avocados alone, says Jillian Michaels, in this divisive video.

  • Big Think's most controversial video of 2019 stirs the pot of the keto diet debate with fitness and nutrition expert Jillian Michaels, who asks: Are keto diet advocates selling people a false—or at least a selective—message?
  • The keto diet increases fat and protein intake while dramatically reducing carbohydrate intake to about 20 grams a day or about 80 calories worth of carbs out of what could be anywhere from a 1600 to 2500 calorie diet per day. That throws your body into a state of emergency called ketosis, which burns fat fast.
  • Michaels' main critique of the keto diet is that there is zero calorie restriction, it cuts out nutrients and digestive enzymes from fruits, and that it's high in animal fats and animal proteins, which negatively impacts telomeres, oxidative stress, and may increase inflammation. Michaels stands by the effects of regular exercise and what she calls a "commonsense diet": don't eat too much, eat real food and get a range of macronutrients.

3 of the most speculative benefits of the keto diet

Can the keto diet really help people combat acne, cancer and "brain fog"?
