I won’t comment on the diet itself but dietitians do not simply rely on guidelines handed to them, nor on anecdotal cases. This article refers to specific studies all throughout, some that support the diet and others that don’t. The goal of a dietitian is to help clients reach their optimal health while still enjoying a high quality of life. I’m sure Abbey is genuinely happy for those it has helped. That does not mean this diet is best for everyone regardless of their unique circumstances, goals and medical history. Sadly there is not enough high quality research that Keto promotes sustained weight loss in the general population. Maybe there will be in the near future, but right now it would be unethical to recommend such a restrictive diet to the broad audience of a blog. I am truly happy it has worked for some people and I wish them luck on their journey. Thank you Abbey for a great article!
But for evidence of the Keto Diet’s more immediate effects, Noakes brings up South African athlete Bruce Fordyce, 60, who won the country’s biggest ultramarathon, the 56-mile Comrades, a record nine times. He ate high-carb his whole life, eventually putting on weight and becoming insulin resistant. Recently, though, he switched to a high-fat diet—and has regained his former waistline and dramatically improved his marathon times. Little by little, according to Noakes, we’re learning. “This is the single most important health intervention we can make as doctors,” he says. “And as nations.”

keto diet what to eat
Don’t be afraid of a banana. Do be afraid of going over your carbs and calories. The same person that will write a hate comment about banans not being keto will sit and eat 10 handfuls of nuts. Guess what, just because you think nuts are a “keto food” you are eating waaaaaayyyyy more calories than you need and you will not lose weight. Keto is not a miracle diet. The laws of science still apply.
Traditionally, in the sports nutrition field, we talk about the importance of timing carbohydrate and fluid intake on improving sports performance. For some time now, research has been looking at the role of very low carbohydrate diets on sports performance. Trailblazers in keto and sports performance research like Dr. Stephen Phinney have been conducting studies in this area since the 80s. In one of his studies, the glycogen stores of cyclists on a keto diet were not completely depleted and lipid oxidation was increased. Researchers concluded that the body was able to adapt to the lack of carbohydrates and preserve what was needed to use the fat as fuel. However, based on the VO2 max breath test, since the body was attempting to preserve the carbohydrate during the exercise, it appears that the intensity of the exercise was limited. In a more recent study, off-road cyclists following a keto diet experienced small improvements, but still not significant enough to make strong conclusions.

I give you points for not completely bashing the Keto diet but I have to ask you why do you think it is hard to follow? Do you tell vegans that their diet in unsustainable? I know for myself I can go to almost any restaurant and eat a keto meal the same could not be said with vegans. A properly balanced keto diet would require no vitamins or minerals (the reason for Keto “Flu”) the same can not be said for vegans, most vegans have major deficiencies and some vitamins like B12 are near impossible to obtain without supplements.
Total carbs is not a precise indicator of the carb content of a food. When you see “total carbs” on a food label, the number beside it represents the cumulative total of grams of dietary fiber, sugar, and sugar alcohol that are in that food item or beverage. Net carb content, on the other hand, relates to the carb content of the food that is digested at four calories per gram and impacts your ketones levels.
