I pulled the published nutrition data for every main on the menus of McDonald's, KFC, Burger King and Jollibee in Singapore and ranked all 109 of them by a single number: calories per gram of protein. Lower is better - more protein for fewer calories.

It is not close. Fried bone-in chicken beats every burger on the board. Five of the top six are chicken pieces, and no beef burger makes the top seven.

Top 15

⚠ Two values are flagged. Burger King's Mexican Drumlets and KFC's 3 pc tenders both pass an internal consistency check on their own macros but fail external plausibility - the drumlet protein load implies far more edible chicken than the portion contains, and KFC's US equivalent tender is listed much higher. If you drop both, the verified top pick is Jollibee's Chickenjoy Drumstick at 11.00 kcal/g.

Which chain should you pick?

Median ratio per chain, across every qualifying main:

KFC is the most reliably protein-efficient chain on a decent sample. Jollibee has the best median and the single best item, but on only eight dishes. Burger King has one outlier then falls off a cliff. McDonald's is the laggard at both ends - worst median and worst best-in-chain, with 50 items and not one under 14.3.

How I calculated it

The ranking number is just stated calories / stated grams of protein. From 221 scraped rows I kept 109: I dropped 30 for having under 12 g of protein (below that the ratio is noise) and 79 by category - drinks, coffee, desserts, fries, sauces and the like.

Every item is then cross-checked against its own macros, 9 x fat + 4 x carb + 4 x protein, flagged if it deviates more than 12%. McDonald's passed on all 99 items.

That check earned its keep. Burger King had published kilojoules in the calorie field on two Ultimate Angus items - stated 1780 kcal against a macro sum of 449. Dividing by 4.184 gives 425, which matches. Corrected here. Uncorrected, both would have ranked as the worst things on the board.

Two limits worth naming: there is no portion normalisation (items are compared as sold, not per 100 g - you buy a drumstick, not 100 g of drumstick), and no bun or batter subtraction, which is exactly why fried chicken wins. The ratio penalises the bread, not the meat.

Sources

Nutrition figures come from the Singapore nutrition pages published by each chain. McDonald's Singapore is the highest confidence (full macro validation pass). Burger King's published data is the least reliable - beyond the two unit errors, its Western Whopper sodium field is also corrupted. Jollibee Singapore publishes no nutrition data at all (its site links only an allergen sheet), so those figures are Jollibee's official published nutrition facts, which match Singapore values on regional databases.

Values are published averages, vary by portion and preparation, and change over time - check current in-store information before relying on any figure.
