Do you wonder why it is that some people can eat whatever they like, and as much as they like, and not become fat, while other people become fat despite not eating a lot and not being lazy? - The explanation is that the people who become fat are vulnerable to salt. For them, eating salt causes them to retain extra bodily fluid and this causes rhem to become fatter and to gain weight.
The groups of people vulnerable to salt are babies and children, people who take or who have taken certain prescribed steroids, including prednisone and prednisolone, or certain other prescribed drugs, women who take or have taken HRT or other oestrogen-containing drugs such as some contraceptive medications, people who take or have taken amitriptyline or other tricyclic antidepressants or some other psychotropic/psychoactive drugs, pregnant mothers, PMT sufferers and people who ate salt as children. These groups need to minimise their salt intake.
Salt Can Cause Obesity
If you fall into one of the vulnerable groups I have listed or if you ate a high salt diet as a child you will be sensitive to salt. People without this problem can eat salty foods without doing a lot of harm to themselves, because their kidneys will excrete the sodium which is excess to their requirements. But for people sensitive to salt, some of the excess sodium, along with the water it attracts, will enter their blood stream and not be excreted. So they carry extra weight - as water - around with them all the time. They also lose more heat from their bodies because the surface area of their body has increased with the added water, and the rate at which a body loses heat is proportional to its surface area. - They therefore need extra calories to do the extra work and to provide the extra heat. - So their appetite increases in order to obtain these extra calories. - So they may very well eat more to satisfy their genuine need for calories. - If what they eat is salty, then the cycle will repeat itself and they are likely to become obese.
To break the cycle and put the process into reverse, all that is necessary for them to do is to eat less salt. And eating extra potassium by way of fresh fruit and vegetables will accelerate the excretion of the sodium and water and speed up the weight loss.
In my opinion, people who remain slim are slim not because they have strong will-power to resist extra calories, but because they have strong-walled healthy veins which can resist the incursion of extra salt water.
