Sweating is your body’s natural mechanism to keep the temperature under control. Excess sweating, whether under armpits, or sweaty hands and feet can lead to bad body odor. A sudden increase in body odor is usually caused by a pungent underarm odor or a smelly groin area. Proteins in the sweat are broken down by bacteria into foul smelling acids. Deodorants are used to avoid the smell and the public humiliation that comes with it, but many now question whether the chemicals used in deodorants are harmful. If you are wondering how to get rid of body odor, then look no further. Our home remedies will stop body odor naturally without deodorants. No more need to smell.
Contrary to popular belief, the body odor is not produced because of too much bacteria on the skin. The unpleasant smell is a result of the breakdown of proteins into different acids.
Yes bacteria play a part, but it is the concentration of protein in the sweat that is the root cause of body odor. 
The odor occurs after the production of two acids – propionic acid and isovaleric acid.
Propionic acid is formed by the bacteria known as propionibacteria. The acid has a pungent smell similar to that of vinegar.
Isovaleric acid is created by Staphylococcus epidermidis bacteria. This acid is also found in different types of cheese.
The sweat that contains the amino acids is produced by two types of glands found on all over the body.
Eccrine glands are responsible for the formation of sweat that goes to the surface of the skin. This sweat plays an important role in temperature regulation. 
Apocrine glands are the main culprit for the undesirable smell. These are present in eyelids, armpits, breasts, and genital area. Other functions of these glands are the creation of earwax and fat droplets in breast milk. 
A sudden increase in female body odor is more distressing then an increase in male body odor. The causes of a sudden increase in body odour arise from the groin and armpits and are nearly always due to the apocrine glands. This is why they are also called scent glands.
These glands typically go into overdrive for two reasons. The first is stress and anxiety. They are activated when you’re under psychological stress. Your nervous system joins in with a racing heart, sweaty palms and dry mouth.
The second reason for a sudden change in body odour is diet. Certain foods have a high sulphurous content which your body may find hard to expel. Spices, garlic, onion, asparagus and sprouts can lead to excretion of sulphur into your sweat.
Finally, body odour is unique to each individual. Health, age, gender, and diet are some of the factors that may affect the smell.
