How to report a concern
Email support@getkalohealth.com with the page URL, the statement or value in question, why it appears incorrect, and any source that may help verify the issue. Please do not include private health information.
How corrections should be handled
- The affected page, source, calculation, and related templates should be checked.
- A safety-sensitive claim should be removed or qualified while it is being checked when leaving it in place could mislead readers.
- A material correction should update the visible content and its modification date.
- The correction note should state what was wrong and what changed without hiding the earlier error.
- If a named review no longer applies after a change, the review attribution should be removed until the new version is reviewed.
Material and minor changes
Material changes include corrected nutrient totals, formulas, source interpretation, medical or safety context, and conclusions that could change a reader's decision. Spelling, formatting, and other minor edits can be fixed without presenting the page as substantively refreshed.

Deficit-size claims corrected in two weight-loss guides
The guide to how many calories a woman should eat to lose weight previously said that a 1,000-calorie daily deficit suits only women with a BMI of 30 or more, that eating 1,000 calories a day triggers muscle loss, gallstones, hair loss, and hormonal disruption, and that 1 pound a week is the rate of fat loss that holds. None of these statements linked a source. We removed them, along with a FAQ answer that repeated them. The section now compares a 1,000-calorie deficit with the deficit sizes and the intake range for women in the 2013 AHA/ACC/TOS adult obesity guideline and the BMI ranges in the 1998 NHLBI guidelines. The guide to staying in a calorie deficit had a table of deficit sizes, weekly losses, and who each size suited that was not tied to a source, and it said a large deficit raises the odds of hunger, fatigue, and rebound eating. We replaced that section with a short sourced summary. It treats weekly loss as arithmetic that tends to overstate results, citing Thomas and colleagues (2013), and links to the deficit-size section of the calorie deficit guide.

1,000-calorie guide: diet category and outcome claims corrected
The 1,000-calorie guide previously said that 1,000 calories a day is classified as a very-low-calorie diet and is below the basal metabolic rate of almost every adult. The guidelines it now cites define a very-low-calorie diet as under 800 calories a day, so the guide shows 1,000 as below the low-calorie diet ranges but above that line, and compares it with resting-energy estimates for five example adults. The guide also said that up to 25% of the weight lost is muscle, that metabolic adaptation lowers calorie burn by 200 to 500 calories, that moderate deficits give 80 to 90% of the same fat loss, and that the first week brings 4 to 8 pounds of water loss. It also gave a 12-week fat-loss comparison, gallstone and side-effect rates, and statements attributed to the National Institutes of Health and the CDC. None of these linked a supporting source, and we removed them. The guide now cites controlled trials of faster and slower weight loss, a review of the "quarter fat-free mass" rule, a gallstone cohort study, and agency pages for each listed risk. A 1992 study of under-reported intake is now described by its published 47% figure, and a 2016 follow-up of "The Biggest Loser" contestants no longer says that most participants regained more weight than they lost. A source labeled as a National Institutes of Health page on very-low-calorie diets linked to a page about prescription weight-loss treatment; we removed it.

Calorie deficit guide: deficit-size claims corrected
The calorie deficit guide previously said that deficits over 1,000 calories a day increase muscle loss, metabolic adaptation, and binge risk, that a 1,000-calorie deficit is generally considered the upper limit and raises the risk of nutrient deficiencies and binge eating, and that research in the International Journal of Obesity consistently shows better long-term outcomes from moderate deficits. None of these statements linked a supporting study, and we removed them. It also presented a 500-calorie daily deficit as producing about 1 pound of fat loss a week. The guide now treats that figure as arithmetic that tends to overstate loss over time, citing Hall and colleagues (2011) and Thomas and colleagues (2013). It cites the deficit sizes in the 1998 NHLBI and 2013 AHA/ACC/TOS adult obesity guidelines, summarizes four controlled studies of faster and slower weight loss with their limits, and shows what a 1,000-calorie deficit leaves to eat at four example maintenance levels.

AI calorie counter accuracy guide rebuilt on checked sources
The AI calorie counter accuracy guide previously gave accuracy percentages by food type and by logging method that were not tied to a source, cited a 2024 paper whose link and DOI we could not resolve, and said food labeling rules allow 20% rounding. We removed those figures and that citation. The guide now reports a 2026 conference abstract, not yet peer reviewed, in which four photo-based apps logged 102 weighed meals about 250 to 345 calories low on average. It attributes the 0.10% to 38.3% error range to the 2023 systematic review that reported it, and it states the label rounding and compliance rules as written in 21 CFR 101.9. It also says plainly that Kalo was not part of that test and has no published validation study.

Citation check completed across all articles
We finished correcting study links in the remaining articles, including guides on alcohol, emotional eating, intermittent fasting, mindful eating, portion sizes, sugar cravings, snacking, grocery budgets, holidays, stress, and clean eating, and fixed several links that an earlier automated pass had accepted because their titles shared generic words. Every PubMed, PMC, and DOI link on the site now points to the work it names. Claims were narrowed to their sources: a 75% emotional-eating figure was removed; the intermittent fasting guide now notes a 12-week trial in which 16:8 eating was no more effective for weight loss than eating throughout the day; sugar-addiction findings are identified as animal research; slow-eating results now describe a single test meal rather than 200 calories a day; tracker accuracy now reflects a study in which no device estimated calories burned within 20% error rather than a 15 to 40% overestimate; and plate-size figures were removed because the evidence is mixed.

Study links and claims corrected in sixteen more articles
We corrected mismatched or unidentifiable study links in 16 more guides, including those on weekend eating, pre- and post-workout nutrition, hydration, eating without counting calories, running, cycling, meal prep, and dietary fat. Several claims were corrected to match their sources: running is now described as linked to more weight loss than walking for the same energy spent (the article previously said the two were similar), weekend eating reflects U.S. survey data of about 115 extra calories per weekend day for adults 19 to 50 rather than 400 to 600, food journaling no longer claims to double weight loss, water-induced thermogenesis now notes its small total effect, and eating before exercise is described as helping longer aerobic sessions rather than resistance training. Unsupported figures, including a 37% thirst-hunger statistic, a 25% calorie reduction, a 25% performance loss from dehydration, and a plate-method result, were removed. We also fixed garbled characters that displayed on the weekend eating guide.

Study links corrected in fourteen more articles
Continuing the citation check, we corrected links in the 20-pound timeline, protein goals, AI calorie counter accuracy, metabolism and aging, travel, calories to lose weight, hidden calories, 1,800-calorie, 1,900-calorie, Cal AI accuracy, night eating, weight fluctuation, calorie deficit, eating out guides. Links now point to the papers they name, labels match the papers they cite, and citations we could not identify were removed. Claims were narrowed to what the sources show: vacation weight gain now reflects a study that measured about 0.7 pounds over a 1- to 3-week trip rather than 1 to 2 pounds per week, a 24% hunger increase is now attributed to two nights of 4-hour sleep in 12 young men rather than one night, the general-health protein figure now states the RDA of 0.8 grams per kilogram instead of 0.8 to 1 gram per pound, and a widely repeated 30 to 50% under-reporting figure now describes the specific group studied. Unsourced muscle-loss, NEAT, and sodium figures were removed.

Mismatched study links corrected in twelve articles
An automated check of every PubMed, PMC, and DOI link found citations whose IDs pointed to unrelated papers, and several labels that named papers we could not find. In the results timeline,scale fluctuation, 30-pound, 50-pound,plateau, monthly weight loss, TDEE,1,000-calorie, 2,000-calorie, and 2,500-calorie guides, we linked the intended papers, relabeled links to the papers they actually cite, and removed citations we could not verify. Claims that went beyond their sources were corrected: fitness trackers are now described by a study finding no device estimated energy burned within 20% error, under-reporting by a study of people who reported not losing weight on low intakes, and menstrual fluid retention by a diary study rather than a fixed pound range. An unsupported muscle-density percentage and unsourced NEAT calorie ranges were removed. The Cal AI alternatives andhow to count calories guides, refreshed the same day, also replaced citations that pointed to unrelated papers. Other affected articles will be corrected and logged here.

Subscription requirement stated accurately
Twelve articles, two calculator result boxes, the homepage FAQ, and the download page described Kalo as free to download with optional in-app purchases. Kalo is free to download, but using the app requires a subscription. We corrected that wording and removed a download-page description that called Kalo the fastest and smartest calorie counter.

Remaining article source-review holds cleared
Following completion of source review, the remaining 12 held articles have been restored as educational content. Each article displays a notice before its body stating that it is for educational purposes only and is not medical advice. No clinical-review credential is claimed. The restored pages also use Kalo's current describe, review, and save workflow in place of retired photo-logging promotion.

1,400-calorie guide restored with corrected sources
The 1,400-calorie guide previously included fixed intake thresholds, linear weight-loss forecasts, and unsupported product claims. The replacement explains individual variation, separates arithmetic from predictions, and links directly to the supporting sources. Its source-review hold has been removed. It is for educational purposes only, is not medical advice, and has not been medically reviewed. The remaining article holds are unchanged.
September 11, 2026
Food-label serving sizes clarified
The food-label guide previously described serving sizes as designed to make numbers look smaller. We corrected this using FDA guidance: serving sizes reflect typical consumption, not personal recommendations. We also replaced unsupported marketing generalizations with linked FDA and USDA explanations, portion calculations, and reviewable food-log examples.
September 9, 2026
Two weight-loss timeline guides corrected
The 20-pound and 30-pound guides previously treated calorie deficits as fixed weight-loss forecasts and included unsupported intake, body-composition, and product claims. We replaced those claims with conditional arithmetic examples, directly linked sources, and individual limitations. Their source-review holds have been removed. These are editorially source-checked educational pages, not clinically reviewed personal plans. The other 13 article holds remain in place.
September 3, 2026
Fifteen articles placed under source review
We marked 15 weight-loss, calorie-target, and AI-tracking articles noindex and withdrew them from Kalo's sitemaps, recommendations, promotional placements, and machine-readable article markup. An audit found unsupported prescriptions or product claims and several citations whose linked studies did not match their labels. The earlier article bodies are withheld until each material claim and reference is corrected. The URLs remain available with a transparent review notice.

Four-food source verification pilot
We reconciled the chicken breast, hard-boiled egg, cooked farmed Atlantic salmon, and cooked quinoa pages with exact USDA FoodData Central records. The salmon page had mixed raw and cooked values and labeled a 178-gram half fillet as a whole fillet. We corrected that preparation and serving mismatch, corrected the other pilot nutrient values, show unavailable trans fat and added sugar as not reported, and calculate vitamin D Daily Value from micrograms instead of treating the source amount as a percent.
September 3, 2026
Food-page provenance and medication claims
We removed unverified FoodData Central record IDs after checking showed that several did not match the displayed food or preparation state. We also removed medication-compatibility ratings and medication-specific FAQs from five prepared-meal pages. At that stage, all food values were labeled as Kalo estimates while record-level and ingredient-level provenance was rebuilt.
September 3, 2026
Product, privacy, and calculator wording
We removed stale rating markup and unsupported quantified product-accuracy and usage claims, replaced absolute privacy summaries with links to the policy, and changed calculator copy so equation-based estimates are not presented as exact or personalized prescriptions.
