Gros vs. dodu vs. obèse
The French words gros, dodu, and obèse all describe someone or something with excess body fat, but they carry very different tones and implications. Understanding the distinction is crucial because using the wrong word can either sound inappropriately medical, overly affectionate, or unnecessarily rude.
Gros
The word gros is the most common and general term for describing someone who is fat or overweight. While it is the standard translation for fat, it can come across as blunt, impolite, or pejorative when used directly to describe a person's appearance.
Il a un gros ventre depuis qu'il a arrêté le sport.
(He has a fat belly since he stopped exercising.)

(My neighbor's cat is really very fat.)

(She no longer wants to wear this dress because she thinks she looks too fat.)

(It is a fat dog that needs a lot of exercise.)
Le médecin lui a dit qu'il était un peu trop gros pour son âge.
(The doctor told him he was a little too fat for his age.)
Dodu
The term dodu translates to plump, chubby, or fleshy. It is a positive, affectionate, and harmless word used to describe an appealing kind of roundness, typically associated with babies, cute animals, or appetizing food like poultry.

(The baby has very chubby little cheeks that make you want to kiss him.)

(The plump bird was pecking at the seeds fallen on the snow.)
Obèse
The word obèse means obese and is primarily a clinical or medical term. It describes a dangerous or unhealthy level of excess body weight and is used as a factual assessment rather than a casual adjective.

(A large part of the population is considered obese in this country.)

Summary
To summarize, use gros as the standard but potentially blunt word for fat, dodu when talking about endearing, chubby roundness in babies or animals, and obèse when referring to the serious medical condition of obesity.
