Celebrity trainer Jillian Michaels is not a fan of the trendy keto diet. The plan calls for eating high fat and low carb meals. Michaels said in a Women's Health video, "I don’t understand. Like, why would anyone think this is a good idea? She continued, "Your cells, your macro molecules, are literally made up of protein, fat, carbohydrates, nucleic acids. When you do not eat one of the three macro nutrients — those three things I just mentioned — you’re starving yourselves.” Michaels said the best diet is a balanced one. She went on to say, "You don’t eat processed sugar, you don’t eat processed grains, and to make a very long story short: avoid the keto diet. Common sense. Balanced diet is key.” What do you think? Do you know someone doing the keto diet? What diet has really worked for you?
