While I do appreciate the amount of research that went into this article, I need to weigh in here— no pun intended. I am a 44 year old woman who suddenly and inexplicably gained a lot of weight at about age 20 and pretty much (albeit a few bouts of massive dieting and exercising) have remained fat until the age of 42. I had always been thin without having to give my lifestyle much thought before my sudden weight gain — so I have spent the last 20+ years becoming pretty proficient on learning how the body uses fuel. I have had success losing great amounts of weight a few times in my life — twice reducing my calories the “nutritional counseling” way — using the old school and outdated food pyramid and tons of exercise. It took literally having to spend hours and hours at the gym — being miserably hungry all the time — only to achieve slow progress at the scale. Months and months I would spent this way only to gain the weight right back the minute that I let go of the reins. I’m always hearing about “sustainable lifestyle changes” from you nutritionists— an I believe in daily exercise — but that lifestyle was completely unsustainable in the long term which is why so many people are unsuccessful.
I am Keto proponent. I have been through muscle cramps when missing greens while riding my bike for 100 km in 5.5 hours (and I am going on 64!) Getting kale and spinach and parsley is a must, getting the fruit whole is a must. Consumption of “good” fats like coco, olive, avocado oils definitely does not hurt. Consumption of meat – and of organs, yes, organs – is very important. And finally, monitoring the body reaction and measuring ketones and glucose helps; I am doing observations regularly. What about G=4.2 and K=.3 in the morning? It is not ketogenic state per se, but in the morning my muscles do not need much fuel, and my frontal cortex and red blood cells need only minimum glucose. What about G=5.4 and K=3.6 in the third hour of bike ride, with acetone in the breath high and ketone disposal in urine very low? What about post-exercise levels of G=4.4 and K=1.2, with almost no acetone in breath and urine levels going sky-high because the body needs not ketones any more?
Truly Dr. Colbert is also a reputable source for more thorough science and modification of previous Keto extremes. The statements about Keto diets with dairy everyday are not true…I am a 66 year old professional (University trained) and have found medical people often very unknowledgable or partially knowledgeable which may be worse. I ask you Abbey to dig deeper…meet Dr. Colbert-not a quack and more in depth than your overview. Personally I am finding switch to more green’s and low glycemic vegetables and fruits with healthy fats, occasional dairy and healthy protein; a way of life that is helping our whole family. Please watch The Magic Pill…the help for family’s caught in old thinking from poor science (ie. Alex Keys) and with autism etc. and so much modern disease is in itself, motivation to search out more truth.
Eliminating several food groups and the potential for unpleasant symptoms may make compliance difficult. An emphasis on foods high in saturated fat also counters recommendations from the Dietary Guidelines for Americans and the American Heart Association and may have adverse effects on blood LDL cholesterol. However, it is possible to modify the diet to emphasize foods low in saturated fat such as olive oil, avocado, nuts, seeds, and fatty fish.
What kind of fruit is Keto friendly
Since the ideal protein intake is fixed based on your lean mass and activity level and your net carbs intake is specified by you, the only macronutrient that needs adjusting is the fat intake. Your fat intake is used to adjust the calorie intake. The more fat, the more calories. Typically, you adjust fat so that you reach but not exceed your target calories.
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.
