Following such a diet means you will be replacing carbs with foods rich in fat and protein, and if followed over an extended period of time this may have consequences. An intake of high fat foods is likely to increase your saturated fat intake which current UK government guidelines recommend that we limit to 30g for men and 20g for women. High levels of dietary protein are thought to be an issue if you have an underlying kidney condition. However, most ketogenic diets supply moderate rather than high levels of protein.
Use fat as a lever. We’ve been taught to fear fat, but don’t! Both keto and low carb are high fat diets. Fat is our source of energy as well as satiety. The key to understand, though, is that fat is a lever on a low carb or keto diet. Carbs and protein stay constant, and fat is the one you increase or decrease (push the lever up or down) to gain or lose weight, respectively. So if your goal is weight loss, eat enough fat to be satisfied, but there’s no need to “get your fats in” once you’re satisfied.
Ang mga malaki, malakas na kalamnan ng Crossfit ay nangangailangan ng maraming protina upang mapanatili ang kanilang lakas. Ang protina ay binubuo ng mga bloke ng gusali na tinatawag na amino acids. May tatlong amino acids na partikular na kapaki-pakinabang para sa pagbuo ng kalamnan at lakas. Ang mga ito ay tinatawag na branch-chain amino acids (BCAAs): leucine, isoleucine, at valine.
A study with an intent-to-treat prospective design was published in 1998 by a team from the Johns Hopkins Hospital and followed-up by a report published in 2001. As with most studies of the ketogenic diet, no control group (patients who did not receive the treatment) was used. The study enrolled 150 children. After three months, 83% of them were still on the diet, 26% had experienced a good reduction in seizures, 31% had had an excellent reduction, and 3% were seizure-free.[Note 7] At 12 months, 55% were still on the diet, 23% had a good response, 20% had an excellent response, and 7% were seizure-free. Those who had discontinued the diet by this stage did so because it was ineffective, too restrictive, or due to illness, and most of those who remained were benefiting from it. The percentage of those still on the diet at two, three, and four years was 39%, 20%, and 12%, respectively. During this period, the most common reason for discontinuing the diet was because the children had become seizure-free or significantly better. At four years, 16% of the original 150 children had a good reduction in seizure frequency, 14% had an excellent reduction, and 13% were seizure-free, though these figures include many who were no longer on the diet. Those remaining on the diet after this duration were typically not seizure-free, but had had an excellent response.
