Day 3: I'm tired AF. Like the kind of tired when you're so exhausted you have to use your left arm to lift your right arm. Somehow, I pried myself out of bed to work out only to realize cardio has never been more hardio, so some chill strength training was going to have to do. (I Now Know These 8 Things About Exercising While On the Keto Diet.) Nonetheless, feelings of lethargy were to be expected, says Dr. Axe, who says days 2 and 3 were also the hardest for him the first time he tried keto. "Every body is different," he assures me. "Some people feel better by day 5, others take two weeks."
There’s room for interpretation in the Mediterranean diet, whether you prefer to eat lower carb, lower protein or somewhere in between. The diet focuses on consumption of healthy fats while keeping carbohydrates relatively low and improving a person’s intake of high-quality protein foods. If you refer protein over legumes and grains, you have the option to lose weight in a healthy, no-deprivation-kind-of-way with a high amount of seafood and quality dairy products (that simultaneously provide other benefits like omega-3s and often probiotics).
The point here is that olive oil is not the magic bullet that made populations along the Mediterranean in the 1950s so healthy. Olive oil was simply a bellweather, or marker, for other features of the Mediterranean diet, like plenty of fruits, vegetables, whole grains, and exercise, that actually did make Mediterranean populations healthier than those in the U.S. or Northern Europe, where more fatty animal products were consumed.
A 2013 study conducted by the German Research Center for Food Chemistry indicates that even just smelling EVOO may lead to greater feelings of fullness: when the scent was added to foods via an aromatic extract, it lowered the number of calories consumed by study participants, and improved blood sugar response. Additionally, compared to other oils and fats, when EVOO was added to yogurt, the group that had eaten the yogurt enriched with olive oil showed the largest increases in blood levels of serotonin, a hormone associated with satiety.
Due to the high-quality design and data of the study, it was published in the Journal of American Medicine, one of the most prestigious research journals in the world. The research team stated that “in this study of overweight and obese premenopausal women, those assigned to follow the Atkins diet had more weight loss and more favorable outcomes for metabolic effects at 1 year than women assigned to the Zone, Ornish, or LEARN diets.” 
Consume more beef and high-fat dairy. These keto foods contain high amounts of a fatty acid called Conjugated Linoleic Acid (CLA). CLA has been found to improve fat loss by a variety of different mechanisms. To get as much CLA as possible, source your dairy and beef from 100% grass-fed cows. CLA content is 300-500% higher in beef and dairy from grass-fed cows, compared to grain-fed cows.
"I'll typically have two chocolate peanut butter fat bombs. They save me. Lately, there’s been a keto cheesecake in the fridge and I’ll sneak a bite, but won’t have a whole piece. I try not to go too hard on the snacks anymore. I’m noticing that laying off the almond flours, coconut flours, and baked sweets has helped me feel better overall. If I want a crunch I’m reaching for the pork cracklings."
The keto diet is notorious for delivering a quick initial slim down. That’s because carbs hold on to more water than protein or fat, says Becky Kerkenbush, RD, a clinical dietitian at Watertown Regional Medical Center. So when you stop eating them, all that extra H2O gets released through urination. As a result, the scale might read a few pounds lower, and you may look a bit leaner.
A study of 39 obese adults placed on a ketogenic very low-calorie diet for 8 weeks found a mean loss of 13% of their starting weight and significant reductions in fat mass, insulin levels, blood pressure, and waist and hip circumferences. Their levels of ghrelin did not increase while they were in ketosis, which contributed to a decreased appetite. However during the 2-week period when they came off the diet, ghrelin levels and urges to eat significantly increased. 
I used the keto guide at http://www.ketocookbook.org and I've lost 25 pounds of fat in one month! Since starting the keto diet, there's one thing I can tell you: the longer you follow it, the more benefits you get! It also gets much easier! That's because, once your body is fat adapted for a long period of time, it get's easier to get back into ketosis. You simply need to train your body to do it. Once you've been fat adapted for a few months, you can even add a few carbohydrates back into your diet from time to time. So understand that you aren't saying goodbye to carbs forever, you are just getting smarter about how to use them!
MCTs and saturated fats are good for you in other ways, too: They reduce the risks of low-fat diets, and they’re supportive of your gut environment, especially since they have the capability to combat harmful bacteria, viruses, fungi and parasites. Additionally, MCTs contain antioxidant properties, which is why coconut oil has far-reaching inflammatory benefits that have led it to be used to treat dozens of health problems in folk medicine for centuries.
And monounsaturated fat isn't the only thing olive oil has going for it nutritionally. Some olive oils come with phytonutrients that may offer their own disease protection benefits (still, it's not clear whether most of us can take in enough of these phytonutrients without going overboard on olive oil, says Joyce Nettleton, DSc, RD, researcher and editor of the PUFA Newsletter).
