Introduction
If during the weight loss process, a daily caloric deficit has already been achieved through proper diet and exercise—meaning more calories are expended than consumed—then, under the premise of controlling total caloric intake, moderate consumption of small lobsters (crayfish) is acceptable. Small lobsters are high in protein and relatively low in fat and carbohydrates, which aligns with dietary recommendations during weight loss.

During weight loss, if you maintain a balanced diet and a certain level of physical activity, you can generally consume crayfish in moderation. However, if improperly prepared, crayfish usually should not be eaten.

If during the weight loss process you have already achieved a daily calorie deficit—burning more calories than you consume—then consuming crayfish in moderation is acceptable under the premise of controlling total calorie intake. Crayfish have relatively high protein content and low levels of fat and carbohydrates, which aligns with the principle of high-protein diets recommended during weight loss.

However, consuming excessive amounts of crayfish during weight loss, or using high-calorie cooking methods such as frying or heavily spiced preparations, may lead to excessive calorie intake, which is detrimental to weight loss. Additionally, if you are personally allergic to crayfish allergic or have gastrointestinal discomfort, you should avoid eating crayfish during weight loss to prevent adverse effects on your health.

The key to weight loss is controlling total calorie intake and maintaining a balanced diet. In daily meals, it is recommended to maintain a balanced dietary structure and diversify food intake, which helps maintain overall health.
