Lost 18 kg over three years while still eating out, by sticking to one rule: 20 g+ protein and 10 g or less fat per meal. Checks every chain’s official data daily.

Two clear groups

Meal items average 590 kcal at Gusto, 555 at Jonathan’s and 595 at Royal Host, versus 436 at Saizeriya and 412 at Denny’s. Under-500-kcal choices make up 64% of Denny’s menu and 57% of Saizeriya’s, but only about 40% at the other three.

Why the low averages

Saizeriya and Denny’s list many small plates, so a two-or-three-dish order lands near the others. Judge by the total — our calculator adds it up.

Salt tells a different story

Average salt per item: Jonathan’s 2.9 g and Gusto 2.3 g versus Denny’s 1.5 g, Royal Host 1.7 g, Saizeriya 1.8 g. Lower calories do not imply lower salt.
