Ariana Grande has not given a detailed, step‑by‑step public explanation for “why she is so skinny now,” but she has pushed back on people commenting on her body and has said that her current body is not unhealthy for her. In a 2023 video, she explained that the fuller body many fans compare her to was actually during a time when she was on a lot of antidepressants, drinking, and eating poorly, and that she considers her current state healthier than that period.

What Ariana has said

In that video, she asked people to be more gentle about talking about others’ bodies and emphasized that there are many different “healthy” body shapes. She also said that fans were comparing her current appearance to a time she describes as her “lowest point,” when her habits and mental health were worse, even if she looked “bigger” then.

Other factors and speculation

Some outlets and anonymous “sources” have claimed her thinness is linked to stress, workload, grief, or very strict eating, but those are speculative and not confirmed by her directly. Online discussions also include unverified claims about eating disorders or extreme dieting, but these come from fans and commenters, not from Ariana or medical professionals.

How to think about this (especially at 20)

Bodies naturally change with age, stress, hormones, and lifestyle, especially in the late teens and early 20s, and that is true for celebrities as well. It is also important not to compare your own body to heavily managed celebrity images, because photos, styling, angles, and health histories you cannot see all affect how someone looks.

If you are worried (about her or yourself)

If Ariana’s appearance is making you feel anxious about your own body or food, it can help to:

• Talk to a trusted adult, doctor, or counselor about how you feel.
• Curate your feeds: mute or unfollow pages that constantly pick apart bodies.
• Focus on how your body feels (energy, sleep, mood) rather than just weight or shape.

If you are personally struggling with eating, obsessing over weight, or skipping meals, reaching out to a health professional or an eating‑disorder helpline in your country is a good next step.
