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.
One group of women still seem to benefit from the popular diet.
- Medical professionals and dieters have long noticed differences in the efficacy of the keto diet between the sexes.
- A new study suggests that estrogen plays a role in preventing women from losing weight on the keto diet.
- More research is needed before scientists know exactly how the keto diet's effects vary between the sexes.
Just because the keto diet is an effective weight-loss tool doesn't mean everyone should try it.
- The keto diet might be a fad diet, but it's unique in that involves putting the body into an alternate and natural metabolic state.
- However, the diet likely isn't safe for everyone, particularly when it's implemented poorly.
- Children, pregnant women, breastfeeding women and those at risk for heart disease should understand the risks of the keto diet before experimenting with it.
Eating a doughnut isn't the only way you can go wrong on the keto diet.
- The high-fat, low-carb keto diet involves putting your body into a natural metabolic state called ketosis.
- When done responsibly, the keto diet can yield a wide range of benefits, most notably weight loss.
- Some people have less luck than others on the keto diet because they make a few common mistakes, including failing to drink enough water, eating too many unhealthy fats, and not realizing which foods might kick them out of ketosis.
Can the keto diet really help people combat acne, cancer and "brain fog"?
- The keto diet is generally an effective method for weight loss.
- Still, many of the diet's other supposed health benefits aren't as well supported by the research.
- Claims that the keto diet can help with acne, cancer and mental clarity are speculative, but there's reason to suggest they're worth investigating.
