What the cheat meal allowance means

MacTrac estimates how many cheat meals per week you can get away with while still moving toward your goal weight. It uses your recent meal tracking and your weight trend, not a fixed diet rule.

The idea is simple: measure the thing you actually control (adherence) against the thing you actually want (your weight trend), and let your own data set the tolerance instead of a generic formula. That also means MacTrac works for any diet, not just keto. If you can honestly answer one question per meal, "did this follow the plan?", MacTrac can learn how much slack your plan really gives you.

How the allowance is calculated

MacTrac looks at:

  • Your logged good vs cheat meals
  • Your recent weigh-ins and whether your trend is moving toward your goal at a meaningful pace, not just the right direction
  • Whether your current trend is already beating the built-in target

If your current pattern is already producing steady loss, the allowance should not warn below behavior that is clearly working.

Under allowance

You still have room in the last 7 days. Keep doing more of what is already working.

At allowance

You are at the 7-day line. More good meals now will protect your trend.

Over allowance

You are leaning past the current estimate. Use more good meals to get back on track.

Your weekly cheat meal allowance

Based on your tracked data and goal percentage, you can have 0 "bad" meals in any rolling 7-day window while still reaching your goal weight.

This is a moving estimate, not a promise. As your tracking and trend change, the allowance can change too.

If your weight trend stalls, or slows to a crawl that would not realistically reach your goal, the allowance does not drop all at once. It eases down by one cheat meal per week until it matches what your recent data supports, and recovers as soon as your trend picks back up.

Improving accuracy

The more consistently you track, the more useful the estimate becomes. For best results:

  • Track good meals and cheat meals honestly
  • Record your weight regularly enough to produce a trend
  • Set a realistic goal weight

MacTrac grew out of a real keto experiment: a chaptered mini-book about making keto stick, from food diaries and latte cuts to grocery systems and carb reintroduction.
