How Much Can You Trust Calorie Labels?

Quote

How accurate are calorie labels and how much do they tell you about the energy your body gets from food? What’s this keto diet that everyone on YouTube is going on about. And what’s with the idea of measuring how much fat you burn by analysing your breath?

Almond bioavailability is lower, AS ARE calories in foods high in soluble/insoluble fibers like beans (eg do you really absorb all the calories in insoluble fibers that first go through gut bacteria?)

I want a calorie-ometer after I go on my next nut binge.

OMG snack foods WOW, this is another reason to NOT trust non-keto processed foods.. Also, 32% less calories in raw almonds?? YES almonds are healthier than other nuts

Also wtf, I eat raw eggplant all the time, it's not toxic

The food label question is irrelevant for me, as it is for most people here, since virtually nothing I have consumed in the past 11+ years on a mildly CR'd diet has a food label. I literally can't think of a single item that does...

Do you grow your own food?
unless you do it must have a label. To be honest I prefer food labels of even vegetables, they are a good approximation, you could look up on sites like cronometer but that in my opinion is a worse estimation than what you get from the merchants because cronometer is user inputted data.

Lastly food labels found on vegetables (for example), are they worked out as raw or cooked? cooking decreases micro nutrients and also effects nutrient absorption.

Another point is not many actually measure to the gram of their foods and can be off even a 100 calories easily. So many factors play a role.

I agree with you, pwonline.

But it is a problem -- it is hard to really know how many calories you are absorbing.  In fact, it's pretty clear that the number of calories actually absorbed by several different people eating the same diet is different.

One of the tricks that I find useful is:  Measure your morning weight immediately after doing your ablutions, prior to eating anything, every morning -- if you change one item in your diet, this measurement (taken the day before, and the day after you make the change), will give you a hint, how the two foods compare, in calories, for you.

good advice, change small part of your diet at a time.
as cr practitioners our calorie intake estimation is important. I find weight measuring a very good tool. At the end of the day we try to be stay consistent and manage best we can.

I ate two entire packs of keto bread believing that it was 0 net carbs (as advertised). It's Aldi's. It was supposedly 35 calories per 28g slice of "keto bread"

The result.. my BG exploded up to a level it has NEVER EVER seen before.

"modified wheat starch" can mean so many different things and is often a sketch ingredient

Hm,

I already wondered about so precise calories counting in the real life scenarios and finally I overcame my laziness and found this:

Intra- and interindividual variability of resting energy expenditure
in healthy male subjects – biological and methodological variability
of resting energy expenditure

DOI: 10.1079/BJN20051551

It is available via scihub.

Authors did some relatively good quality measurement of resting energy expenditure variability to confirm that for a person there could be several percent variability in a normal, stable lifestyle, w/o heavy excercising, diet changes, deseases, etc.

Also they referred to another study where intrapersonal variability is estimated as around 10%.

Given the BMR value of around 1500kcal for not much active person it seems narrowing to 50-150kcal/day estimates based on published values of different food types should be taken with a big grain of salt. The same 5-15% variability is perhaps a norm for any product in addition to metabolic variability, sugar-rich plant and so on.

My own observations are similar, sometimes I am pretty stable in weight with constant -100kkcal/day in cronometer, sometimes I am gaining weight slowly with zero balance, sometimes I don't with +100. I am learned how to distinguish oscillations caused by slight diet changes where glycogen stores are growing or depleting (and gut microflora is rearranging), so I am not taking into account such transitional changes.

Is so precise (e.g. ~100kcal/day) estimates with cronometer and food labels really working for somebody on a few weeks/months periods?

Most CR veterans stop counting calories after a while, and either eat the same thing every day or go by body weight.

I eat exact same meal everyday.

I eat ~480 grams of raw broccoli and roughly ~480 raw collard greens (spring greens)

Sometimes I go slightly over (500g raw collard greens) and those calories even though are minor still test my OCD.

so I adjust my EVOO consumption, it just fluctuates within a gram of EVOO lol.

but I still force myself to weigh everything, I'm relatively still starting out on CR (around a year so far) so maybe in time I'll relinquish this added responsibility but 

I like to remind my conscious and sub conscious that we must not break this routine no matter what. Like a daily affirmation to my will power and desire to see this experiment (CRON) through till I die LOL

It's good that you are realizing you are suffering some form of fixation,  may be a fully-fledged OCD.

If I can speak freely, none without a fixation would ever worry about 20 grams of collard greens or one gram of EVOO (which is also often within the error of measure of the system).

I agree but isn't it true all CRONNIEs suffer the same issue LOL. The things i've read about taking multiple supplements and long chemical names and constant blood tests. I literally eat whole foods, no supplements except potassium and sodium and spend 1.25 hours eating a day. but I love this community for sharing all the knowledge and experience 🙂
