View Full Version : Question about fitday

It seems when fitday calculates total calories it doesnt just multiply Carbs x 4,it seems to subtract the fiber content. Is fitday calories trust worthy then?

Also does this seem right to yall: I cut up a small Haas avocado into cubes and that comes out to about 1/2 cup or 121 calories and 11 g of fat. Does that seem right for an avocado? I always thought avocados were more calorie/fat dense.

Thanks.

I would go with weight over cups for veggies.

Just continue to track those size avocados the same way each time and you'll be fine. Until of course you can get a more accurate method.

So using volume (cups) is not accurate method?

If for instance you were to weigh an avocado, i presume its after its been peeled and the seed removed?

cups are better for liquids. I just perfer a scale.

yes weigh it peeled and skinned, fitday should be able to account for that.

Im worried that I have been underestimating the avocado now. Is there anywhere I can see a whole avocado, unpeeled, should weigh?

Mr. D

I just weighed them whole, they are 200g. That translates to 7.14 oz.

I wonder what that translates to.

I'm bored so here ya go.

Avocado (http://www.nutritiondata.com/facts-B00001-01c20Tk.html)

Google is your friend.

I was on there at the sametime, however it doesnt tell me what 1 fruit with skin and seeds weighs.

I think ive been grossly underestimating the 1/2 cup cubes and 121 calories.

If this small haas avocado is like 280 calories, what does one of those BIG ones have.

Read the labels on the food you buy, then make your own custom foods for everything you eat.

Getting labels on fresh produce can be tricky sometimes...

You don't count fiber as it isn't digested. I think :scratch:

As for the fruit just weigh it if it's that big of a deal. Otherwise just make sure you are consistent in your approximations. Precision not accuracy ;) In the end it won't make a difference... If you're underestimating them and you start gaining weight continue to input them the same way but just lower your total calories...

As long as you count it the same everytime, it won't matter. If you are actually eating 400 cals in avocado but only measuring it as 150 on fitday, your numbers will be skewed a bit from reality, but your just going to land up adjusting your daily cals anyways. If your daily adds up to 2500 on fitday and your hitting your goals (either gaining or losing) then it doesn't matter if your really eating 2900.

fitday subtracts fiber because fiber cannot be used for energy and therefore is a 'zero net calorie' form of carbs.
also, alcohol is a carb with 7cals per gram instead of four, which can make calories seem 'off' if you go drinking with buddies on a cheat day.

if you really want to be accurate on food, get a good kitchen scale. we got a nice Salton at bed bath and beyond for $50. grams, oz, pounds, kilos, zero's out at the touch of a button, its great.

I got a cheapo $20 electronic scale at Radio Shack - nice and small, accurate in grams and ounces, and portable.

Use the USDA nutrient database (http://www.nal.usda.gov/fnic/foodcomp/search/) to programme in foods you're not sure of.

I did this for avocado and programmed it in.

An ounce of avocado (28g, edible portion) according to the USDA nutrient database is as follows:

Energy 45 kcal
Protein 0.5634g
Total lipid (fat)4.1035g
Carbohydrate 2.39g
Fiber, total dietary 1.9g

Built, could you tell me the model number and manufacturer of that scale, Im trying to see if its still available.

Any of these. (http://www.thesourcecc.com/estore/Category.aspx?language=en-CA&catalog=Online&category=KitchenScales&pagenum=1&sort=1)
I got this one, (http://www.thesourcecc.com/estore/Product.aspx?language=en-CA&catalog=Online&category=KitchenScales&product=6313003) but any will do.

Precision not accuracy


First year chemistry talking.

Fiber cant be absorbed by the human digestive system, thus why it is used to solidify... erm... turds...

Therefore the calories you would have otherwise gained are not counted.

I bought a food scale and I have to say it's the best $30 I've spent in awhile

I just bought a foodscale today from Walmart for 29.99. Hopefully i enjoy it as much as yall.

Mr. D

So i weighed the aforementioned avocades. After they were peeled and seed removed, 88g.

That puts them at 160 cals. So I guess I wasnt too far off.

I bought a Good Cook brand from Walmart for 29.99 and like a lil kid look forward to preparing my meals and using my new little toy. No longer need to use all my measuring cups and the beating of cleaning them.
