Conceptual Metaphor
INVADER/POLLUTANT (an external agent that invades the body and corrupts its normal metabolic processes).
Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid direct calque like 'ожироген'. The concept is typically translated descriptively as 'вещество, способствующее ожирению' or 'ожирогенное вещество'.
- Do not confuse with general terms for 'fattening food' (e.g., 'калорийная пища'). An obesogen is a specific disruptor, not just high-calorie.
Common Mistakes
- Pronouncing it as /ɒbˈsɒdʒən/ (incorrect stress and vowel sounds).
- Using it as a general synonym for 'junk food'.
- Misspelling as 'obesogene' or 'obesogin'.

FAQ
Frequently Asked Questions
Yes, it is a legitimate, though highly specialized, scientific term coined in the early 21st century from 'obesity' and the suffix '-gen' (meaning 'producer of').
In the strictest sense, obesogens refer to chemicals that disrupt hormonal pathways. However, in extended use, some experts refer to ultra-processed foods or high-fructose corn syrup as 'obesogenic' due to their metabolic impact.
In British English: /əʊˈbiːsədʒ(ə)n/ (oh-BEE-suh-juhn). In American English: /oʊˈbisədʒən/ (oh-BEE-suh-juhn). The stress is on the second syllable.
Both are formed with the suffix '-gen' (producer). A carcinogen produces cancer. An obesogen produces or promotes obesity. They are both types of harmful agents studied in public health.
