# Evaluate a 6-Week Weight Loss Plan: 3 Checks for 1–2 lb Weekly Loss

Lily Armstrong · November 11, 2026

> Apply 3 checks before paying for a 6-week weight loss plan: a 6–12 lb rate claim, a weekly-average trend rule, and an all-in cost per expected pound.

Apply these checks before paying, and require the plan to state its all-in cost per expected pound before week 1. A plan that passes the rate and trend checks but hides cost or promises an adult result from a youth review has not met the standard.

## Compare Four Plan Types by Three Checks

Compare plans by the three checks, not by marketing labels: the rate claim must land inside 6–12 lb over six weeks, the trend check must use a weekly-average rule with a pre-set stop or revise trigger, and the cost check must state all-in cost per expected pound before week 1. A plan that passes one or two checks is still a fail.

For an illustrative calculation, add all itemized six-week costs into one all-in total, then divide by both endpoints: all-in total ÷ 6 lb and all-in total ÷ 12 lb. The same total produces a higher cost per pound at 6 lb than at 12 lb, so compare both figures before paying.

Use this worksheet to compare plans on equal terms before week 1. A low upfront fee can mask recurring food, appointment, supplement, or travel expenses that raise the all-in total, while a higher-priced program may include items you would otherwise buy separately. Enter each line item, convert weekly charges to a six-week total, and compute both cost-per-pound figures for every option you are considering.

Treat the money check as a pass-fail gate alongside the other credibility checks: if a provider cannot itemize all-in costs or will not let you calculate cost per expected pound at 6 lb and 12 lb, you do not have enough information to commit. Paying only after you know the cost per expected pound at both endpoints keeps the financial decision aligned with the plan’s promised results.

## Worked Example: Run the Numbers

Illustration only: one adult enrollee chooses a six-week target of 9 lb, which sits inside the 6–12 lb credibility band, records three weigh-ins each week, and receives an all-in cost quote before week 1. Use the plan’s quoted all-in total for any cost-per-pound calculation; no specific price is assumed here.

| Step | Calculation | Result |
| --- | --- | --- |
| Weekly target | 9 lb ÷ 6 weeks | 1.5 lb/week |
| Six-week total check | 1.5 lb/week × 6 weeks | 9 lb |
| Cost per expected pound | quoted all-in total ÷ 9 expected lb | cost per expected pound |

The trend check uses the average of the three weekly weigh-ins, not one day's change. Example weigh-ins of 1.2, 1.6, and 1.4 lb average to (1.2 + 1.6 + 1.4) ÷ 3 = 1.4 lb/week, which stays inside the 1–2 lb/week review band, so the plan continues unchanged. Weigh-ins of 0.6, 0.8, and 0.7 lb average to 0.7 lb/week, which triggers the pre-set stop or revise rule before more money or effort is committed.

The money check is applied to the same 9 expected pounds: divide the quoted all-in total by 9. If two plans both target 9 lb, compare their totals on this basis; the lower value wins only if the plan also passes the target and trend checks.

Winner for this example: the multicomponent plan with weekly average and stop rule, because it is the only candidate that can satisfy all three checks at once. Break-even trigger: stop or revise if the rolling weekly average is below 1 lb/week or above 2 lb/week, or if its cost per expected pound is no longer the lowest among qualifying plans.

This example is an illustration of arithmetic and decision rules, not evidence that any specific program works; the 9 lb target and 1.5 lb/week rate are used only to show how the checks are applied.

## Limits, Stop Rules, and Your 6-Week Audit

A credible six-week plan also states where its own rules stop working. The 1–2 lb/week band is a target for the weekly average, not a promise that any single week lands inside it, which is why the audit needs stop rules for edge cases in addition to a weekly target. This section supplies those limits: the edge-case table and the five if/then decision rules below.

Edge case one is a high baseline water shift. Many adults drop several pounds of water in the first week; when a single week exceeds 2 lb/week, the single-week cap no longer reads cleanly. The plan still holds up only if that spike triggers a 2-week average review, confirming the following two weeks settle back toward 1 lb/week before you continue.

Edge case two is medication or a missing scale. Diuretics and steroids move fluid independent of fat loss, and a standard-deviation trend assumes averaged weights cluster within a predictable range that a minimum and maximum can be calculated around (Wikipedia). When that assumption fails, the SD/trend rule can mislead: switch to clinician-confirmed weights and extend the review window rather than trusting home readings.

Edge case three is pediatric growth charts. WHO's weight-for-length/height standards are z-score charts covering birth to 2 years (WHO); they do not measure adult six-week loss. Reject any plan that substitutes pediatric z-scores for the adult rolling average, and apply the adult trend check instead.
