The regulations define those claims per reference serving rather than per 100 g, so treat these as a like-for-like comparison between foods, not as a statement about a product label:
- Low calorie — 17 kcal per 100 g (≤ 40)
- Low fat — 0.1 g per 100 g (≤ 3 g)
- Low saturated fat — 0 g per 100 g (≤ 1 g)
- Very low sodium — 16 mg per 100 g (≤ 35 mg)
- Sugar free — 0 g total sugars per 100 g (< 0.5 g)
- Keto-friendly — 3.4 g net carbs per 100 g (≤ 5 g)
