The Claim

In adults with overweight or obesity undergoing caloric restriction, higher protein intake (79 g/day) is associated with greater intake of green vegetables and lower intake of refined grains and added sugars, independent of total energy intake.

Source: Higher protein intake during caloric restriction improves diet quality and attenuates loss of lean body mass

What the research says

Supports is higher

Support is ahead, but a single strong opposing study can change this.

These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.

In plain English

Among adults with overweight or obesity who are reducing calorie intake, those consuming 79 grams of protein per day eat more green vegetables and fewer refined grains and added sugars than those consuming less protein, even when total calorie intake is the same.

See the scientific wording

In adults with overweight or obesity undergoing caloric restriction, higher protein intake (79 g/day) is associated with greater intake of green vegetables and lower intake of refined grains and added sugars, independent of total energy intake.

Why this might work

When protein intake increases, it triggers signals in the gut and brain that reduce hunger and increase fullness, causing the body to prefer foods that are filling without adding many calories, like green vegetables, and to avoid foods that spike blood sugar quickly, like refined grains and sugars.

  1. Study: Higher protein intake during caloric restriction improves diet quality and attenuates loss of lean body mass

    People who ate more protein while dieting also ate more broccoli and spinach and less white bread and candy—even when eating the same number of calories as others. The study found this pattern for real.
