This was an awesome read, man! Convinced me to go Keto again, as I’ve had great results in the past. I workout 3-4x a week heavy lifting (powerlifter), but my weight has gotten too high for me. 5’8″ 21y/o Male, 223 pounds, but a lot of muscle mass. I’m ready to transition my focus to fat loss, mostly for health and body composition reasons, and the fact that diabetes run in my family and most my relatives have it!! I refuse to be apart of that! So thank you for this awesome read and inspiring article. Awesome job on your progress!!
First, start with a tablespoon and increase the amount over time. Another option is to mix olive oil in a blender with a cup of warm water and the juice of a lemon. It makes it much more palatable and the lemon juice will help with the easier digestion of the oil. Plus, lemon juice has been linked to improved liver function. A healthy liver produces more bile, which in turn is needed for the proper breakdown of fats (and oils) in the small intestine.
Gut health is extremely important for anyone looking to lose weight and increase overall health[*][*]. It is not uncommon for those who shift to a ketogenic diet to have a change in the production of bacteria in their colon (although not necessarily a bad thing – just a change)[*]. To help support this change and increase the healthy bacteria in your gut, try consuming more fermented foods such as sauerkraut, kimchi or kefir and/or supplement with a high-quality probiotic[*][*].
They can also improve your cholesterol profile. In one study, consuming MCT oils helped reduce body fat and triglycerides more than omega 6 vegetable oils. After eight weeks, the experiment showed the MCT oil group lost more weight, body fat, and subcutaneous fat, all while experiencing a 15 percent drop in triglycerides and LDL (the bad) cholesterol.
For example, a 2003 study published in the Journal of Obesity and Related Metabolic Disorders showed that after comparing long-term consumption of MCTs and LCTs on energy expenditure, body composition and fat oxidation in obese women, the MCTs had more significant effects. Substitution of MCTs for LCTs in a targeted energy balance diet proved to offer better prevention of long-term weight gain due to increases in energy expenditure and fat-burning. (2)
One review, published in April 2016 in The American Journal of Medicine, looked at five research trials on overweight and obese people and found that after one year those who followed a Mediterranean diet lost as much as 11 pounds (lbs) more than low-fat eaters. (6) (They lost between 9 and 22 lbs total and kept it off for a year.) But that same study found similar weight loss in other diets, like low-carb diets and the American Diabetes Association diet. The results suggest, the researchers say, that “there is no ideal diet for achieving sustained weight loss in overweight or obese individuals.”
Con: Results can vary depending on how much fluid you drink. By drinking more water, you dilute the concentration of ketones in the urine and thus a lower level of ketones will be detected on the strips. The strips don’t show a precise ketone level. Finally, and most importantly, as you become increasingly keto-adapted and your body reabsorbs ketones from the urine, urine strips may become unreliable, even if you’re in ketosis.
When examining the studies, the researchers noted that, on average, the participants in the VLCKD groups lost about 2 lbs. more of bodyweight compared to the low-fat diet groups.  This difference was statistically significant and described as “moderate”. The researchers also noted greater improvements in triglycerides, blood pressure, and HDL cholesterol in the VLCKD group compared to the low-fat diet group.
The findings below have been limited to research specific to the ketogenic diet: the studies listed contain about 70-80% fat, 10-20% protein, and 5-10% carbohydrate. Diets otherwise termed “low carbohydrate” may not include these specific ratios, allowing higher amounts of protein or carbohydrate. Therefore only diets that specified the terms “ketogenic” or “keto,” or followed the macronutrient ratios listed above were included in this list below. In addition, though extensive research exists on the use of the ketogenic diet for other medical conditions, only studies that examined ketogenic diets specific to obesity or overweight were included in this list. (This paragraph was added to provide additional clarity on 5.7.18.)
HDL cholesterol has long been considered “good” because it is largely responsible for picking up excess cholesterol from tissues, including the artery wall, and bringing it back to the liver for disposal. This process is known as reverse cholesterol transport. It’s easy to remember if you think of HDL as the garbage trucks that help rid the body of garbage (LDL).
People if you stick to what he says you will lose the weight. The first 1.5 weeks are tough. The rest are a lot easier. You get an energy high after the 3rd week. Never have I had so much energy. I am down 27lbs in 7 weeks. I only workout 3 times a week and its only 45 minutes. This whole write-up he did is very thorough and encouraging. I am sure he has help hundreds of people.
A systematic review of 26 short-term intervention trials (varying from 4-12 weeks) evaluated the appetites of overweight and obese individuals on either a very low calorie (~800 calories daily) or ketogenic diet (no calorie restriction but ≤50 gm carbohydrate daily) using a standardized and validated appetite scale. None of the studies compared the two diets with each other; rather, the participants’ appetites were compared at baseline before starting the diet and at the end. Despite losing a significant amount of weight on both diets, participants reported less hunger and a reduced desire to eat compared with baseline measures. The authors noted the lack of increased hunger despite extreme restrictions of both diets, which they theorized were due to changes in appetite hormones such as ghrelin and leptin, ketone bodies, and increased fat and protein intakes. The authors suggested further studies exploring a threshold of ketone levels needed to suppress appetite; in other words, can a higher amount of carbohydrate be eaten with a milder level of ketosis that might still produce a satiating effect? This could allow inclusion of healthful higher carbohydrate foods like whole grains, legumes, and fruit. 
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).
