What is the Fat Burning Index ™?
The FAT BURNING INDEX™ is a tool allowing to describe potential influences
of foods on lipolysis - "burning" the body's fat for fuel. We
use the standard "ketogenic ratio" approach to calculate it. The
higher the index, the more body's fat can (potentially) be burnt. To lose
body fat, one should eat foods with Fat Burning Index ™ greater than 1.5.
Only then the body will recognize its own fat as fuel and burn it. We use
this technique to make our dieters lose fat without watching portions and
counting calories, fats, or carbohydrates.
The Fat Burning Index ™ is what
we've done with all-science 'ketogenic ratio' of foods and meals. We
used a scientific formula recognized by clinicians and fitness professionals
- but we adapted it to the needs of a normal, regular person, without serious
diseases (always - always! - consult with your physician before you start any
diet!) and not aiming for a bodybuilding competition.
We also recognize this person's natural tendencies -- to get bored on a
strict diet, to cheat time and time again, to come close to giving up. Our
Fat Burning Index ™ approach allows you to have any food.
"ANY food? So can I eat all I want?"
We promise that as long as you eat
the foods we suggest, you will never count calories. You might want to ask:
"So what's new? This is exactly what all low carb diets promise, don't
Right. But we go much further. We promise that you will not count
carbohydrates, fats, or protein. If you find a single diet, online or
offline, that frees its dieters from that much counting, let us know and
we'll cheerfully refund your money and send you a $20 Amazon.com gift
certificate. Does this sound too good to be true?
You might be doubtful and chances are that mainstream diets are the reason.
Of course you couldn't avoid opinions like the below Q&A posted by Health
Care Reality Check:
Q: Can a person eat unlimited calories, and still lose weight, as long
as they severely restrict carbohydrates?
A: No, she can not. The basis of ketogenic diets, such as the Atkins
Diet, is a severe restriction of carbohydrate calories, which simply causes a
net reduction in total calories. Since carbohydrate calories are limited,
intake of fat usually increases. This high fat diet causes ketosis (increased
blood ketones from fat breakdown), which suppresses hunger, and thus
contributes to caloric restriction. -- Ellen Coleman, RD, MA, MPH
Is this a correct answer?
Let's first discuss whether it's a correct question. Or, rather, is this the
real question so frequently asked by dieters. In my experience, this in fact
sounds a little bit different but this makes ALL the difference. This is what
real dieters ask:
Q: Can low carb dieters eat all they want, and still lose weight as
long as they only eat allowed foods?
A: Yes, they can. The basis of ketogenic diets, such as the Atkins
Diet, is a restriction of carbohydrate-containing foods in favor of fat and
protein containing foods, which causes the state of ketosis resulting in
significant decrease in appetite. Since appetite decreases, most of low carb
dieters consume significantly less calories WITHOUT INTENTIONAL CALORIE
Let's see why and how it happens
Ketosis is a biochemical condition that occurs when the body produces ketones
at a higher rate than glucose's release into the blood.
Ketone bodies provide energy for the body's needs when there is a total food
restriction, carbohydrate restriction, and/or long enough physical effort.
In the beginning of ketosis, ketones provide up to 75% of total energy
requirement, including energy required by the brain. Most dieticians say that
carbohydrate is the only fuel for the nerve cells but it is not true. It's a
preferred fuel, yes, but not the only one. If there are little or no
carbohydrates, all tissues of the body including brain tissue can adapt to
using alternative fuel.
As the body undergoes the process of adaptation to ketosis, the amount of
carbohydrates required reduces. This explains why brain fog and muscle
weakness can occur in the beginning of ketosis but becomes very rare after a
week or two. In fact, it's true that a diet is considered low carb if it
contains less than 100 carb grams a day, but it's only true until the
adaptation to ketosis develops. After it is completed, the carb requirement
is around 40 grams. None of non-clinical low carb diets takes this fact into
After 1-2 weeks, as the process of adaptation to ketosis develops and the
tissues no longer rely on carbohydrates for fuel, they send less signals
requesting the beta-cells in the pancreas to release insulin -- resulting in
decrease of insulin concentration in the blood.
Low insulin level frees its antagonistic fat burning hormones from
suppression resulting in increased levels of glucagon, growth hormone,
catecholamines, and glucocorticoid.
Glucagon is the most important insulin antagonist; it's up to glucagon to
control fatty acids' release from fat stores to be burnt for fuel. So, as
glucagon release increases, insulin goes down. It is thought that to initiate
ketosis, carbohydrate intake should be reduced to less than 30g/day.
However, there's a most important condition grossly overlooked by the authors
of low carb diets. Any food is either ketogenic or glucogenic depending on it
influence on the competition between glucagon and insulin. To make ketosis
possible, a meal should contain at least 1.5 g of fat per every 1 g of
protein plus carbohydrate combined.
Only that or higher of a ratio makes food ketogenic enough to allow eating
without portion and calorie control. Foods with ketogenic indexes below 1
promote insulin release and are essentially anti-ketogenic. Foods with
indexes between 1 and 1.5, though not anti-ketogenic, require calorie control
since their ketogenic properties are not strong enough to significantly
suppress the carbohydrate metabolic pathway and mobilize body fat for fuel
thus causing healthy hunger decrease.
