> but they still contain too much starch and it is impossible to use them exclusively to provide enough proteins within a diet of not more than 2000 kcal/day, suitable for a sedentary life style.

Lentils have 26g of protein and 353 calories per 100g, and eggs have 13g of protein and 143 calories per 100g, so the ratio is 13.5 for lentils and 11 for eggs.

Doesn't seem all that different.

Whole eggs, like also most kinds of dairy, have similar amounts of fat and proteins, so indeed they are not much better as sources of proteins than nuts or seeds.

On the other hand, lean meat is almost pure protein, so its ratio of protein vs. energy is 3 to 4 times better than for vegetable sources.

Even with whole eggs, you can get much less calories than with lentils, if they are used to supplement cereal proteins, because they have a significantly better lysine to calories ratio, so when the amount of required lysine is specified you can eat less of them than in the case when their amount would be computed to provide a specified amount of protein.
