A useful number, with its assumptions attached.
Who publishes this
HeyCoach is a WhatsApp nutrition coach published by Massively Parallel Thoughts, LLC. The guides carry the HeyCoach organizational byline. That byline names the publisher, not a clinician or registered dietitian.
We write about calorie targets, food logging, protein and the practical work of keeping a useful record. Every new user gets seven days of Pro free with no card; after that the coach pauses until you subscribe at $4.99 a month or $39.99 a year, and there is no free plan. The website calculators are free to use.
Sources and review
Nutrition articles link to research papers, public-health agencies and other primary sources. Product comparisons use official pricing and feature documentation, with the checked date stated in the article. Worked examples are labeled as examples, not customer results or clinical outcomes.
These pages are not yet reviewed by a registered dietitian. When one reviews a page, a “Reviewed by” line on that page says so.
The calculators explain their formulas and limits. The calorie target uses the same calculation as the WhatsApp coach. The deficit calculator's slowing curve is an educational approximation, not the full NIDDK Body Weight Planner. Historical “ideal weight” and body-fat estimates are presented as references rather than prescriptions.
How comparisons are written
We make HeyCoach, so we have a commercial interest in it. Every comparison says so, describes what the alternatives do well and includes HeyCoach's limits. There is no public head-to-head test of accuracy, retention or weight loss across these apps, so we compare workflow, price and friction instead.
