I don't know if they can. I've never tried it. I now rough estimates of what the calories and macros should be on most things so its easy to spot something not quite right.
Way too complicated. Lol. Not really. Pen and paper, love your dedication but way too much work for me.
^ see D1cko's post - that basically sums it up.
When I hear of people measuring things insanely down to the last gram.. it's seems crazy to me (unless you are striving for competition level bf). What if you run for the train that day and burn an extra 20 calories? Do you need to eat an extra 5g of sweet potato or an extra 7g of white potato? What if you have cold water today instead of room temperature water and you burn an extra 60 calories?
Honestly - the freedom you get when you realise that you don't need to be so retentive about it, it's incredible.
See Pistachio's thread, I've been using his approach (inadvertently) since about March and I've been able to clean bulk 3-4kg just by working at eating consistently the same things rather than accurately measuring every bit eg I can't know exactly what's in the portions of dinner my wife makes, but I know roughly I'm getting about 30g protein, no more than about 10g fats and about a serve of carbs (ie 30-40g). I then just factor that in with the other meals which I prepare and keep consistent.
And yes I know that a bulk is different to a cut, but I'm heading into a short cutting phase and I expect to have similar results.
Just relaxIf you use daily burn you will get huge variances in everything eg apples will vary from 17-30g even for the same size apple.
If you have an iPhone you can download the myfitnesspal app which has an inbuilt barcode reader. Just scan the barcode of whatever you're eating and it should find a match.
The potatoes i currently have, "Woolworth's golden delight brushed potatoes" don't have the nutritional facts mentioned on the sack, but once i scan the barcode it comes up with-
Potatoes- Brushed-(Aust) (Fresh)
serving size - 100g
60 calories
0g fat
11.2g carbs
2.4g protein
you think you know what your eating, But you would ve very supried if you actaully weights and loged it all- unless you ahve done that in the past, Are now eating hte same meals therefore that would be the ONLY way to have a rough estimate at best.
My Fitness Pal allows you to set up your own data base of foods that you regularly eat, for example I made my own shakes, and gave them different names, so when I have a shake with berries, wpi, milk and honey I know what macros I have consumed. did the same for various breakfasts and lunches I have at work.
Not concerned about how complicated it is, just how time consuming it is. At the moment I'm just trying not to get fat until I can start training again, so it would be a decent time to trial it, I guess.
