An elephant, a hippopotamus, a gorilla, a horse, a salmon fish, a chicken, a tiger, a cat, a dog and a very long list of animals regardless of size, shape, weight, foods and natural habitat are all generally fit. If we assume that the BFP or “Body Fat Percentage” is a meaningful measure of being overweight, then accordingly a range in the 20% or below is healthy. Well interestingly those animals easily fit into that range. Furthermore, none of them follow diet plans nor do they suffer a natural food restriction plan. Meaning that they eat as much and as often as they can or want. Even the foods that they eat vary widely from being plants, grains, fish, or meats and they can weigh tons or a few kilos and be huge or slim but in general terms they are fit. Would it not be wonderful if it were the same case for us humans ?
