Weight loss is the category where a generic chatbot does the most damage. The default template wants to close: it quotes calorie targets, promises 30-pound transformations on a timeline, recommends supplements it knows nothing about, and pushes a one-click checkout to anyone who asks. The prospects who get hurt by that conversation are exactly the ones a careful coach would want to slow down for: chronic dieters with restriction-binge cycles, prospects on GLP-1 medications under a clinician's care, postpartum parents in body-image distress, and people who have been failed by every previous program. SleekAI flips the default. The system prompt is configured with explicit refusals on pound-loss timelines, body-fat-percentage targets, calorie or macro prescriptions, supplement recommendations, and any framing of coaching as treatment for obesity or any medical condition.

Goal sorting still works inside that frame. A prospect wanting sustainable habit change, a perimenopausal client navigating hormone-related shifts, an adult wanting general weight loss for joint health, and a postpartum parent rebuilding a relationship with food all need different conversations. The bot reads the goal at a high level, surfaces the right package (habit block, sustainable change, perimenopause-focused), and books the discovery call. No pound-loss promise. No transformation language. No 30-day countdown.

Disordered-eating routing is non-negotiable. Any mention of restriction history, binge episodes, purging, laxative use, compulsive exercise, body-image distress, or active eating-disorder concern is routed to a clinical referral path with NEDA's hotline surfaced. The bot does not run an intake, does not propose a calorie number, and does not push a self-serve checkout. Coaches working in weight loss field these signals constantly, and the bot has to be the first careful filter.

Weight loss is the chatbot conversation with the highest mismatch between marketing default and human need. The default template across the SaaS chatbot space promises pound-loss numbers, quotes calorie targets, recommends supplements, and pushes a one-click checkout to anyone who asks. The prospects most likely to fill the inbox at 10pm on a Sunday are exactly the ones who should not get that conversation: a chronic dieter who has been through every program and has a restriction-binge cycle they have not named yet, a postpartum parent in body-image distress, a perimenopausal client navigating hormone-related shifts, a prospect on a GLP-1 medication whose questions belong to a clinician, and the occasional prospect with undisclosed clinical-level eating disorder.

SleekAI flips the optimisation entirely. The system prompt is configured with explicit refusals on pound-loss timelines, body-fat-percentage targets, supplement recommendations, calorie or macro prescriptions, GLP-1 dosing or side-effect advice, and any framing of coaching as treatment for obesity or any medical condition. The disordered-eating routing is non-negotiable: any signal of restriction history, binge episodes, purging, compulsive exercise, or body-image distress routes to a coach review with NEDA's hotline surfaced (1-800-931-2237 in the US or an equivalent local hotline).

The GLP-1 and bariatric history routing is also non-negotiable: those questions go to the prescribing clinician. Inside that safety frame the bot is genuinely useful for the prospects it can serve. It explains the coach's approach honestly, quotes accurate package pricing, captures the intake in conversation, and hands the qualified prospect to Calendly with flags surfaced for the coach.

Discovery calls end up shorter, more honest, and better matched. Coaches working in weight loss are the ones who most often deal with the consequences of generic chatbots crossing into clinical territory, and a properly configured bot is the difference between a practice that fields the right prospects and a practice that spends Mondays apologising for what a chatbot said on Sunday night.
