Insects generally have a higher food conversion efficiency than more traditional meats. While many insects can have an energy input to protein output ratio of around 4:1, raised livestock has a ratio closer to 54:1 [6]. This is partially due to the fact that feed first needs to be grown for most traditional livestock. Additionally endothermic (warm-blooded) vertebrates need to use a significantly greater amount of energy just to stay warm whereas ectothermic (cold blooded) plants or insects do not. [7] An index which can be used as a measure is the Efficiency of conversion of ingested food to body substance: for example, only 10% of ingested food is converted to body substance by beef cattle, versus 19-31% by silkworms and 44% by German cockroaches. Studies concerning the house cricket (Acheta domesticus) provide further evidence for the efficiency of insects as a food source. When reared at 30°C or more and fed a diet of equal quality to the diet used to rear conventional livestock, crickets showed a food conversion twice as efficient as pigs and broiler chicks, four times that of sheep, and six times higher than steers (oxen) when losses in carcass trim and dressing percentage are counted.[1]

A female cricket can lay from 1,200 to 1,500 eggs in 3 to 4 weeks, while for beef the ratio is four breeding animals for each market animal produced. This gives house crickets a true food conversion efficiency almost 20 times higher than beef.[1] For this reason and because of the essential amino acids content of insects, some people propose the development of entomophagy to provide a major source of protein in human nutrition. Protein production for human consumption would be more effective and consume fewer resources than vertebrate protein. This makes insect meat more ecological than vertebrate meat.
Insects have many attractive qualities for food production besides their high energy efficiency. For example the spatial usage and water requirements are only a fraction of that required to produce the same mass of food with cattle farming. Production of 150g of grasshopper meat requires only very little water, while cattle requires 3290 liters to produce the same amount of beef.
