AI로 내 체형을 9가지로 바꿔보기!
제미나이에 사진 1장을 넣어 같은 사람을 9단계 체중으로 보여주는 3x3 이미지를 만드는 프롬프트예요. 얼굴은 알아볼 수 있게 유지돼요.
💡 정보는 매일 2~3시간 동안 큐레이팅해서 무료로 공유해드려요.
제미나이(나노바나나 프로)에서 원하시는 사진과 아래 프롬프트를 넣고 제작하시면 됩니다.


Use the uploaded image as the base identity reference.
Create a single 3x3 grid image showing the same person across
9 clearly separated body weight levels.
Both body shape and facial features should change naturally
according to weight, while the person remains clearly recognizable
as the same individual.
IDENTITY RULE (CRITICAL):
All 9 images must depict the SAME PERSON.
Facial identity must remain recognizable at all times.
No face swapping, no cosmetic surgery look, no beautification.
Eyes, nose, mouth shape stay structurally the same.
Facial changes are allowed ONLY as natural weight-related fat changes.
GLOBAL CONSISTENCY:
Same pose, same camera angle, same lighting, same background.
Same outfit style; only the fit changes naturally with body size.
Ultra-realistic DSLR photography.
No stylization, no illustration, no cartoon.
FACIAL TRANSFORMATION RULES:
As weight decreases: face becomes slimmer with reduced cheek fat,
but never skeletal or sick-looking.As weight increases: face becomes progressively fuller,
rounder cheeks, softer jawline, thicker neck.No extreme hollow cheeks, no exaggerated jaw, no grotesque distortion.
Avoid any disease, starvation, or disturbing appearance.
BODY TRANSFORMATION RULES:
Body fat and volume change realistically.
Natural fat distribution (face, neck, abdomen, waist, arms, thighs).
Clothing reacts naturally: loose → fitted → tight → strained.
No warped anatomy or unrealistic proportions.
9 DISTINCT LEVELS (VERY IMPORTANT — NO SKIPPING OR JUMPING):
VERY SLIM (fashion-model thin, healthy):
Low body fat but NOT extreme
Slim face with slight cheek volume remaining
Defined jawline without sharp angles
Narrow neck
Clothing looks loose but clean
THIN (naturally slim):
Slightly fuller face than #1
Soft cheek volume begins
Jawline less sharp
Neck slightly thicker
Clothing fits cleanly, not loose
SLIM:
Balanced slim face
Normal cheek volume
Natural jawline
Clothing fits normally
LEAN / FIT:
Athletic silhouette
Firm facial contours
Stable jaw and neck
Clothing looks fitted
AVERAGE:
Neutral proportions
Average facial fullness
Slightly softer jawline than #4
Standard clothing fit
SLIGHTLY OVERWEIGHT:
Mild belly and waist increase
Face slightly rounder
Softer jawline
Subtle neck thickness
Clothing slightly tight at waist
OVERWEIGHT:
Clear waist and abdomen growth
Thicker arms and thighs
Noticeably rounder face
Early double chin
Clothing visibly tight
SEVERELY OBESE:
Heavy fat accumulation
Wide torso
Very round face
Clear double chin
Thick neck
Clothing stretched and strained
EXTREMELY MORBIDLY OBESE (super-obese):
Massive body volume
Extreme abdomen and torso width
Heavy fat folds
Extremely round, full face
Very thick neck
Unmistakably super-obese appearance
SEPARATION RULE (ANTI-JUMP):
Each level must be clearly different from adjacent levels.
The transition from #1 to #2 must be subtle, not dramatic.
Avoid sudden jumps in body mass between neighboring levels.
Differences must be obvious even at thumbnail size.
OUTPUT & QUALITY:
One single 3x3 grid image.
Ultra-high resolution.
Natural skin texture.
No AI artifacts.
No text, no UI, no watermark.
