The exact proportions of carbs, fats, and
protein vary from person to person.
Consistency — how much does the gene for
this protein vary from person to person?
Not exact matches
I convinced three key
people — my boss, Professor Alan Fersht
from the Medical Research Council (MRC) Centre for
Protein Engineering in Cambridge, U.K.; the 1997 Nobel Prize in Chemistry winner Sir John Walker
from the MRC Dunn Human Nutrition Unit, also in Cambridge; and Dr. Fergal Hill
from the European Molecular Biology Laboratory in Heidelberg, Germany —
to join our synergistic technologies and
varied expertise.
Since then, evidence has emerged that the crucial human
proteins are HLA antigens,
proteins that appear on the surfaces of cells and
vary from person to person.
It is possible for excess
protein to cause an increase in blood sugar levels, however this potential
varies from one
person to the next, and the blood sugar elevations that do occur in some
people are no match for the big spikes that can be caused by excess carbohydrates (especially refined and high glycemic index carbohydrates — see carbohydrates page).
The exact amount of
protein needed
varies from person to person but for a rough guide 1.5
to 2 grams of
protein for each kilogram that you weigh is the best amount of
protein you should consume if you want
to keep your muscle whilst the fat leaves the building.
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.
A
person's required
protein intake
varies and depends on your sex, height, weight and exercise levels but a normal
protein intake ranges anywhere
from 20
to 50 grams with each meal.
The key is not only
to get adequate
protein, but optimum
protein, as well as all the other nutrients the body needs, which of course will
vary from person to person, and depend upon lifestyle.
Also,
to mention the Atkins diet, in the book I read, the diet begins with a two week very low carb diet [20 grams of carbo perday] in order
to transition the body into a state of nutritional ketosis, using ketones not glucose / insulin for energy generation; however, it is not intended
to be a permanent such state but rather for the dieter
to gradually add in carbs; however, is one added in only up
to the limit, which
varies from person to person, of carbs
to just below the lvel that would transition out of ketosis, then Atkins would work with that in mind and requiring monitoring for blood or urine ketone levels and must needs be high fat,, moderate
protein, and low carbs
