When the math isn't working

The most common email to TrakMac support: 'I've been hitting my targets for weeks but my weight isn't doing what it should.' Cutters say it about not losing. Bulkers say it about not gaining. Both are usually right that something's wrong, and usually wrong about what.

In most cases, the targets aren't calibrated quite right for your specific metabolism. The TrakMac math uses Mifflin-St Jeor plus your fitness profile to estimate calorie needs. The estimate is good — about ±200-300 calories accurate for most adults — but every individual has their own variance, and that variance compounds over weeks.

This article walks through the diagnostic and the fix.

First: are you actually hitting your targets?

Before concluding the math is wrong, verify the inputs. Three quick checks:

1. Are you logging consistently? Check your last 4 weeks. If you have more than a few days under 1,000 calories logged, you're either skipping logs or genuinely under-eating. Both produce inaccurate trend data.

2. Are you logging fully? Many people log meals but forget snacks, drinks (especially alcohol — calories add up fast), cooking oils, condiments, sauces, and 'tastes' from cooking. A few hundred uncounted calories per day completely changes the math.

3. Are you under-estimating restaurant meals? Restaurant portions are often 30-40% larger than home portions, and oils/sauces add hidden calories. If a meaningful portion of your eating is restaurants, the estimates may be systematically low.

If any of these check boxes don't pass, fix those before adjusting targets. The fix is logging discipline, not target adjustment.

If logging is genuinely accurate and consistent, move on to target recalibration.

How to adjust the target

For cutting (you want to lose weight, scale isn't moving)

The daily calorie target is too high. Your actual maintenance is lower than the calculator estimated, so what TrakMac thinks is a 400-calorie deficit is actually closer to maintenance.

Adjust:

  1. Lower the daily calorie target by 150-250 calories. Set it manually in Settings → Targets.
  2. Hold for 3-4 weeks. Don't adjust again before then. You need real signal.
  3. Check the 4-week trend. If weight has dropped 1-3 lbs over the period, the target is now correct. If still no movement, lower another 150-200 calories and repeat.
  4. Don't drop below your calorie floor (10 calories per pound of bodyweight is a reasonable floor — for most adults that's 1,500-2,000). Below the floor, metabolic adaptation accelerates and you make the problem worse.

In most cases, one adjustment is enough. The original target was off by 200-300 calories due to individual metabolic variance.

For bulking (you want to gain weight, scale isn't moving)

The daily calorie target is too low. Your actual maintenance is higher than the calculator estimated.

Adjust:

  1. Raise the daily calorie target by 150-250 calories. Set it manually in Settings → Targets.
  2. Hold for 3-4 weeks.
  3. Check the trend. If weight has gained 1-2 lbs over the period, the target is correct. If still no movement, raise another 150-200 calories.
  4. Watch for body composition as you go up. The goal is muscle gain plus modest fat gain, not unconstrained weight gain. If gain is too fast (>1 lb/week sustained for someone past their first year of training), the surplus is too aggressive.

For maintenance (you want to stay the same, scale is moving)

If you're trying to maintain and you're losing weight, the target is too low — raise by 150-200. If you're gaining, the target is too high — lower by 150-200.

Maintenance recalibration matters most after a cut or bulk. Your post-cut or post-bulk maintenance is different from what it was before, and the calculator doesn't always catch the metabolic adaptation. See why maintenance is harder than cutting for context.

Why TrakMac's initial estimate may be off

The Mifflin-St Jeor equation that underpins TrakMac's calorie targets is the most-validated RMR formula in the literature. For 80% of adults, it's accurate within ±10%. For the other 20%, individual variance produces meaningful gaps.

Factors that the formula doesn't fully capture:

Lean body mass beyond what fitness signals predict. Someone who's been training for 10+ years and carries unusually high lean mass for their height/weight burns more calories than the formula predicts.

Naturally high or low NEAT (non-exercise activity thermogenesis). The fidgeter who can't sit still burns 200-400 more daily calories than the equally-trained person who's calm. Genetic.

Thyroid status. Hyper- or hypothyroid conditions shift RMR up or down meaningfully. If you're an outlier in either direction, the formula won't catch it.

Recent extreme weight changes. Post-cut metabolic adaptation can drop maintenance by 5-15% beyond what the formula predicts.

Medications. Some medications (steroids, certain antidepressants, some diabetes medications, GLP-1s) affect metabolism in ways the formula doesn't account for.

None of these are bugs in the math. They're individual variance the math can't capture without personalized blood work and metabolic testing.

How long to give it before adjusting again

A common mistake: adjusting targets every week based on day-to-day weight fluctuations.

Daily weight fluctuates by 2-5 lbs based on sodium, glycogen, fluid balance, GI contents, hormonal cycles. A single weigh-in tells you nothing about your weekly trend.

The right approach:

  • Weigh daily (same time, same conditions — first thing in the morning, after bathroom, before water/food)
  • Track the 7-day rolling average, not single days
  • Wait 3-4 weeks between target adjustments
  • Use the 4-week trend to evaluate, not single weeks

If you adjust every week, you'll chase noise and never know what's actually working. If you wait 4 weeks, you have real signal.

When the issue isn't calorie target at all

A few cases where weight stagnation has a different cause and adjusting calories won't fix it:

Strength training adds muscle while you cut fat. Newer trainees can simultaneously lose fat and gain muscle, especially in the first 1-2 years of training. Scale weight stays flat while body composition changes meaningfully. The fix isn't target adjustment — it's adding measurements (waist, photos, lifts) to track real progress.

You're in a perimenopausal or hormonal shift. Hormonal changes can cause 3-5 pounds of water retention that masks fat loss for weeks. The fix is patience and longer-window evaluation, not target adjustment.

You're chronically under-sleeping. Sleep deprivation impairs both fat loss and muscle gain through hormonal disruption (cortisol, leptin, ghrelin). If you're averaging under 6 hours, sleep is the lever, not calories.

You're severely under-fueled relative to training. The body downregulates metabolism when chronic underfueling persists. The fix here is counterintuitive: eat more for 4-6 weeks, then resume the cut. Sometimes the way out of stalled progress is up first.

You're stressed and over-cortisol. Chronic high stress affects body composition in ways calorie math doesn't capture. The fix is stress management, not more aggressive cutting.

What TrakMac does when you adjust

When you manually override a target in Settings:

  • The new target persists indefinitely until you change it again
  • Your dashboard immediately reflects the new target
  • Your streak math uses the new target's deficit/surplus framing
  • The fitness assessment isn't re-run automatically — your override is your override

If you want TrakMac to recalculate from scratch (e.g., you've gained or lost a lot of weight, or your training has changed substantially), use Settings → Retake fitness assessment. See how to retake the fitness assessment.

The summary

  1. First check that you're logging accurately. The math can't help if the inputs are wrong.
  2. Adjust the daily calorie target by 150-250 in the right direction.
  3. Hold for 3-4 weeks before evaluating or adjusting again.
  4. Use the 4-week trend as your signal, not daily weights.
  5. If stagnation persists across multiple adjustments, consider non-calorie causes (sleep, stress, hormonal, medication).

Most stalled progress is solved by one or two target adjustments and 4-8 weeks of patience. The math is calibrated to your specific metabolism after that, and the trend resumes.
