Why am I hungry after eating a salad?

Usually because the salad was short on protein and on calories. Leaves are mostly water, so a big bowl of greens with carrots, cucumber and a spoon of dressing is about 140 calories with 6 g of protein, which is a snack. Add your protein line and something with fiber past the leaves, and the same bowl becomes lunch.

A salad looks like a lot of food. The bowl is full, it takes a while to eat and it feels like a meal, but your body is counting calories and protein. Four cups of romaine fill a big bowl and have about 32 calories, fewer than one hard-boiled egg.

Leaves are like kindling, a big pile that burns out fast, and the protein and the beans are the logs that keep the fire going.

The same bowl, fixed in two steps

Graded on the six meters Gyroscope grades a meal on, for a 170 lb person eating 2,000 calories over three meals, with the same leaves in all three. The chicken clears Muscle, but at about 280 calories the bowl is still too light to be lunch, and the bottled Italian is a big share of it. The chickpeas and the oil fix both.

The five usual reasons

1. Short on protein. Leaves have about 1 g a cup. A 2015 review of the protein research found people felt fuller after higher-protein meals and put the helpful amount at about 25 to 30 g a meal or more. They didn’t eat less at the next meal in those short trials, so the effect is modest, but feeling fuller is what you want from lunch.
2. Too small to be lunch. On a 2,000 calorie day, a 150 calorie salad is about a quarter of a meal, and hunger at three is your body asking for the rest.
3. Most of it is dressing. If half the calories are ranch or caesar, the bowl has the calories of a small meal with almost none of the protein or fiber. A side salad with 2 tablespoons of ranch is 78% dressing.
4. No fiber past the leaves. Half a cup of chickpeas adds about 6 g of fiber and 7.5 g of protein for 134 calories. Corn, black beans or quinoa work too.
5. It was a starter. A light salad before dinner isn’t meant to hold you, and it’s doing its job when it doesn’t. In a Penn State trial, a big, light salad eaten first cut the whole lunch by 12%.

The quiz also checks for fat. With no fat on the salad you absorb almost none of the beta-carotene in the vegetables, so keep a tablespoon of oil even when you’re cutting calories.

Bigger bowls do help, when they’re a meal

In a year-long Penn State trial, 97 women with obesity were told to eat less fat, and half of them were also told to eat more water-rich food, mostly fruit and vegetables. Neither group had a calorie target. Of the 71 who finished, the vegetable group ate a greater weight of food, lost 17.4 lb (7.9 kg) against 14.1 lb (6.4 kg), and reported less hunger.

If your bowl has all of this and you’re still hungry by three, the salad probably isn’t the problem. Look at breakfast, sleep and the rest of the day.
