The Help option displays this page in the unit's web browser, and the About options shows a page containing copyright and other information about the program. The Hacker Diet help button opens the Hacker Diet website in the browser (maeFat is very similar to the Hacker Diet "Eat Watch"). |

- | + | The Settings page allows you to change how the program operates. It must be used initially to enter your height. Before entering your height, you should select centimeter units if that's what you wish to use (rather than inches). You may also select metric units for weight, and the format for displaying the dates. If you select nonjudgemental colors, neutral colors will be used to display the data, otherwise green will be used to indicate weight loss, red will be used for weight gain, and the BMI data will be color coded. The BMI color code is: | |

- | There is | + | There are four "radio box" sets of buttons. The first allows you to set whether your goal is to lose weight or to gain weight. The green/red color coding of weight changes will be set depending upon this setting. The second set of buttons allows you to define the format for printing dates. The |

+ | be done. | ||
- | + | For the least squares fit time interval, you may chose either "Fit Interval" or "Fit After Date". If you chose "Fit Interval", you may then select a window which specifies the time range for the data that will be fit. For example, if you select "Fit Last Month" then the weight log entries for the last 31 days will be used for the least squares fit. If you select "Fit After Date", then you may select a specific date after which all the weight log entries will | |
+ | be used for the least squares fit. To disable least squares fitting, select | ||
+ | "Fit Interval" and "Don't Fit Data". | ||
- | + | There is also a button labeled Start with Data Entry. Selecting that option | |

The Trend Page shows statistical information about your weight data over differing time intervals. Initially, when little data is available, it will show only the values for the entire log history. Eventually data for the last week, fortnight (2 weeks), month (30 days), quarter (91 days) and year will be shown, when enough data is available to calculate those values. | The Trend Page shows statistical information about your weight data over differing time intervals.

The weight values shown on the Trend Page are calculated with these formulae, and the caloric excess/deficit values are calculated using the difference in trend value over the specified interval, with the assumption that one pound of weight change corresponds to 3500 calories. | The weight values shown on the Trend Page are calculated with these formulae, and the caloric excess/deficit values are calculated using the difference in trend value over the specified interval, with the assumption that one pound of weight change corresponds to 3500 calories. | ||

Once you have selected the month and have pushed the View Selected Month button, you will be presented with a page listing all the data entries for that month. The green weight values are the measurements that you have entered. The yellow weight values are trend weights, calculated with one of the formulae shown above. If you press on one of these entries, you will be sent to the Data Entry page, which will be preloaded with the selected day's values, where you may change the values. You may also press the Delete button to remove the entry entirely. | Once you have selected the month and have pushed the View Selected Month button, you will be presented with a page listing all the data entries for that month.
