The Daily Summary Results Explained

Daily Details

The day's food and exercise in an easy to read format.

I think that these summary rows are mostly self explanatory.

Glycogen is displayed as three values, percentage of maximum calculated capacity, weight in kilograms and kilo calories available. Once you become familiar with glycogen these numbers can be quite informative as glycogen can easily become a "borrowed" weight loss.

The ketones column has n/a as ketosis is not yet supported.


Summary

Summary Row

Did much happen today, probably not, one day is rarely significant?

This summary row shows the weight gain or loss and the energy consumed and expended as well as the changes in glycogen level for the day.

The thing to be aware of is that that glycogen depletion can overstate a weight loss.

Like all summary rows, the value in the Total Body Weight column is the change over the period, the day.

Grand Total Summary Row

Well, have I lost or gained weight?

This summary row totals weight gain or loss and the energy consumed and expended as well as the changes in glycogen level.

The thing to be aware of is that that glycogen depletion can overstate a weight loss.

Like all summary rows, the value in the Total Body Weight column is the change over the period, the whole simulation.


No Imaginary Losses

Glycogen Adjustment Summary Row

No Sneaking Glycogen Depletion Into The Numbers.

This summary row adjusts the values in the Grand Total row so that the glycogen levels are at 100% of the calculated maximum capacity for the body.

This may be useful as glycogen depletion is usually temporary but has a dramatic effect on weight, witness the "success" of the low carb diets such as Atkins.

If you select Set Basic Example Values and remove the food and exercise after 3 days you will you lose 2.11kg, but this row compensates for the glycogen used during this period. Doing this shows that the "real" loss was only 0.56kg.

Like all summary rows, the value in the Total Body Weight column is the change over the period, the whole simulation.


That Doesn't Seem Right

The Calories In The Difference Column And The Total Body Weight Column Seem Wrong

The summary lines are wrong, aren't they, the weight gain and calorie difference don't equate?

They are not, but I can see why you might think so.

Digesting food requires energy, the Thermal Effect of Food and in this simulation this is taken from the Glycogen stores.

So when looking at Protein and Fat eaten the Difference column and the Total body weight column (which is the change in the summary lines) should always come out as the number of calories in a pound of body fat. If no exercise is being performed.

When looking at carbs the energy derived and the cost both affect into the glycogen column, so the energy derived and the cost of the digestion partially cancel out the changes to the total glycogen level.

The calculator also has different digestion costs for converting carb to glycogen and fat, with the conversion to fat being significantly more expensive. This means that once the body's maximum glycogen level is hit some carbs go to glycogen and some to fat with varying costs.
