2. Weight Loss
One major reason lettuce can be an ideal weight-loss food is its calories. One serving of lettuce contains just 5 calories. Moreover, lettuce helps bridge the micronutrient gap that is otherwise hard to achieve on a low-calorie diet.
Lettuce is also extremely low in fat. Adding one large leaf of Romaine lettuce to your lunch could be a good idea. However, there is no direct research stating that lettuce may help with weight loss.
