Does protein bar cause acne?

Protein bar may add to breakouts if you eat it often or in large amounts.
One serving brings a high glycemic load (fast sugar, which raises insulin), a lot of dairy (milk hormones) and a little saturated fat or omega-6. It also gives omega-3, which the research links to calmer skin.
Why this score
- Glycemic: 25 g carbs at GI 45 = glycemic load 11.3 (high). Fast sugar raises insulin, and insulin can lift skin oil and clog pores.
- Dairy: 20 g. Milk proteins may act like growth signals; for some people they raise skin oil within a few days.
- Inflammation: 4 g saturated fat and 0.8 g omega-6, a small load.
- Skin Boost: 0.1 g omega-3, which small trials link to fewer inflamed spots (+0.8).

- Fruit and nuts
Not medical advice. This score is for protein bar on its own. What you eat with it changes the result: protein and fat slow the sugar spike, and breakouts usually show up 3 to 7 days after a meal, which is why SpotBite tracks your meals over time rather than judging one food. Diet is one factor among many (hormones, genetics, skincare, stress, sleep).
