Even when we eat very little, inappropriate diet means

that our organs are not able to function properly as they are not able to process and excrete as many toxins as we put into our body.  Obesity, cellulite, degenerative illnesses and damages in the body are caused by inappropriate lifestyle and diet.
Most problems arise from the intestines and unhealthy gastrointestinal microbiota and oversaturation with toxins.  The reason is inappropriate combination of food in meals, improper eating of fruit, eating too much processed and canned food and concentrated proteins of animal origin (meat, milk, eggs), drinking alcohol, smoking and stress.
It can be concluded that nearly all health problems are directly or indirectly associated with inappropriate diet. Being overweight and some symptoms of metabolic disease undoubtedly lead to more serious health issues. One of the most common health problems is diabetes. Healthy life style and  maintaining appropriate body weight may postpone the development of diabetes to later in life or even prevent it. Among others, health issues include unregulated blood fats, high blood pressure, atherosclerosis, obesity. Recently, the emergence of visceral adipose tissue around internal organs has been the subject of numerous research.  It has been found out that this is not only the tissue for storing excessive energy but acts as an organ, interfering with metabolic processes. It releases mediators, called adipokines, which play a role in the process of chronic inflammations, affect satiety, they are connected with the development of insulin resistance and cardiovascular diseases.

An old Latin proverb says: Eat to live, not live to eat.
