What Is The Minimum Carbohydrate Intake Necessary To Spare Body Protein And Prevent Ketosis?

Dietary Protein Requirements

This is a summary/extract from The Ketogenic Diet by Lyle McDonald. […] too much protein can prevent ketosis as well, disrupting the adaptations which ketogenic dieters seek. Therefore, protein intake must fall within a narrow range: high enough to prevent muscle loss but low enough that ketosis is not disrupted. After much research, it was concluded that a protein intake of 1.5-1.75 grams protein per kilogram of ideal body weight would spare most of the nitrogen loss, especially as ketosis developed and the body’s glucose requirements decreased. Assuming zero carbohydrate intake, during the first 3 weeks of a ketogenic diet a protein intake of ~150 grams per day should be sufficient to achieve nitrogen balance. Therefore, regardless of bodyweight, the minimum amount of protein which should be consumed during the initial three weeks of a ketogenic diet is 150 grams per day. After 3 weeks of ketosis, as little as 50 grams of protein per day should provide enough glucose to achieve nitrogen balance. The consumption of carbohydrate will decrease dietary protein requirements since less glucose will need to be made from protein breakdown. For example, if a person was consuming 125 g Continue reading >>

    When embarking on a ketogenic diet for health or fat loss, finding the optimum protein intake can be very confusing for many beginners. For smooth adaptation in the transition to a ketogenic metabolism I typically guide people using a caloric spread of around 70-80% fat, 15-25% protein, and 5% carbohydrate from green fibrous vegetables – but this ratio varies for every individual and using percentages is confusing and misleading in many cases. ...

    Figuring out how many carbs to eat when you have diabetes can seem confusing. Meal plans created by the American Diabetes Association (ADA) provide about 45% of calories from carbs. This includes 45–60 grams per meal and 10–25 grams per snack, totaling about 135–230 grams of carbs per day. However, a growing number of experts believe people with diabetes should be eating far fewer carbs than this. In fact, many recommend fewer carbs per day ...
