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. ---------------------------------------------------------------------------------- JILLIAN MICHAELS Jillian Michaels is a fitness expert and wellness coach with over 20 years experience and is a New York Times bestselling author of numerous books including Master Your Metabolism, Unlimited: How to Build an Exceptional Life, and her most recent The 6 Keys: Unlock Your Genetic Potential for Ageless Strength, Health, and Beauty.

And the problem is what people will do to try to sell you a false bill of goods is take one study and blow that study out as though it's the entire picture, when of course it isn't. Imagine you have a massive painting but I only showed you this tiny piece of the painting but you had no idea what the hell else was going on over here there, there's no way you could get an accurate read on if this is a sad picture, a happy picture, like there's no way you could know, correct? So when we look at keto here's why we're saying, or not me, but here's where some of the advocates are espousing benefits. Well, what are we doing with keto? We're removing carbohydrates, anything that elevates you got about 20 grams of carbohydrates a day that you're ingesting, which is essentially nothing, it's about 80 calories worth of carbohydrates out of what could be anywhere from a 1600 to 2500 calories a day diet so that's nothing. And it throws your body into a state of emergency that's what ketosis is. And because we don't have any glucose or glycogen, any blood sugar or stored blood sugar, we turn to fat quickly. We produce ketones and the idea is we burn through fat and we lose fat fast. And that is true and you would think that would be a good thing. And in addition, people will say well I reversed my type two diabetes. Of course, your insulin level was through the floor, you're consuming zero carbohydrates so you have no blood sugar so your pancreas is not releasing insulin. And this can also affect conditions like polycystic ovarian syndrome and by virtue of that connection, it can also affect fertility. Fair. Let's give it that. But here's what we're not talking about, there's zero calorie restriction on a ketogenic diet so you have a massive amount of oxidative stress, there's no consideration of timing with regard to food so your autophagy process is totally out of whack In addition to that, it's very high in animal fats and animal proteins. So we're seeing that diets rich in saturated fats are poor for our telomeres oxidative stress, increased inflammation, your nutrient-sensing pathways that are related to the health of your metabolism are overrun with constant food, heavy fats, lots of animal protein and we know it hurts your telomeres and on and on and on. Now, what about the benefits? Is it worth it? Let me tell you, the number one way to sensitize somebody's body, again to insulin, is exercise. I've been doing this a heck of a long time...
