Almond mom means: A mother who promotes (or herself follows) an inadequate diet with poor nutritional value and low calories, usually to promote a slender body image.. It is internet-era slang, commonly seen on TikTok, Discord, Reddit or X. There is no real cause for parental concern; it is descriptive vocabulary rather than risky behaviour. If your teen uses it, context will usually make the intent clear. A short, curious question about where they heard it is usually all that is needed to know whether to follow up.
