Foods that provide both protein and fiber may help with weight loss.
Eggs are a popular food, particularly for breakfasts, that may help promote weight loss.
In a small study of 21 men, researchers compared the effects of eating eggs or eating a bagel for breakfast on food intake, hunger, and satisfaction.
They also looked at levels of blood sugar, insulin, and ghrelin, which is also known as the hunger hormone.
They found that men who had eaten the egg breakfast ate significantly less at their next meal, and in the following 24 hours, than those who had eaten the bagel breakfast.
Those who had eaten the eggs also reported feeling less hungry and more satisfied 3 hours after breakfast than those who had eaten the bagel.
After breakfast, the egg group also had less of a change in their blood sugar and insulin levels, as well as lower ghrelin levels than the bagel group.
Starting the day with a bowl of oatmeal could also result in a lower number on the scales.
A study involving 47 adults looked at differences in appetite, fullness, and next meal intake after participants ate oatmeal, as opposed to an oat-based ready-to-eat breakfast cereal.
After eating oatmeal, participants felt significantly fuller and less hungry than after eating the cereal. Also, their calorie intake at lunch was lower after eating oatmeal than after eating breakfast cereal.
While both breakfasts contained the same amount of calories, the oatmeal provided more protein, more fiber, and less sugar than the cereal.
The authors concluded that the difference in fiber, specifically a type of soluble fiber called beta-glucan, was probably responsible for the results.
Oatmeal is available for purchase online.
3. Beans, chickpeas, lentils, and peas
As a group, beans, chickpeas, lentils, and peas are known as pulses. They may influence weight loss due to their effect on fullness, as well as their protein and fiber content.
Similarly to oatmeal, pulses contain soluble fiber that may slow down digestion and absorption. Eating protein leads to the release of hormones that signal fullness.
Researchers analyzed studies that had looked at the effect of the consumption of pulses on weight loss.
Weight loss diets that included pulses resulted in significantly greater weight loss than those that did not. Weight maintenance diets that included pulses also resulted in weight loss compared with those that did not.
