It is not recommended to feed cats too little food for a long time, because cats who are not full for a long time can easily cause physical diseases, the most common of which is fatty liver.

For people, eating too much is easy to get fatty liver, and cats will get fatty liver (hunger) if they eat less.

Fasting, excessive dieting or other rapid weight loss measures can cause a large increase in lipolysis in a short time, consume glutathione (GSH) in the liver, increase malondialdehyde and lipid peroxide in the liver, damage liver cells and lead to fatty liver.

In other words, when cats eat less or are malnourished, the body will break down its own fat and release fatty acids and triglycerides. Some fatty acids enter the blood and eventually flow into the liver; Most of the rest is for muscles.

But some cats, especially fat cats, can't do this. The liver can't process fatty acids, which leads to fatty acids accumulating around liver cells and hinders the normal function of the liver.

Data show that adipose tissue, or fat meat, produces different results in different locations. For example, it seems that a signal will be generated in a fat cat, which will prevent the body from properly using fat as an energy reserve, and at the same time increase insulin resistance and hinder blood sugar metabolism.

The fatter the cat, the higher the chance of getting sick. In particular, cats who are completely on hunger strike should not eat too little. Generally speaking, fat cats are prone to fatty liver if they don't eat for three days. It is estimated that they eat too little in about two weeks.

Therefore, in order to lose weight for a cat, we must not eat too little, but step by step. You can feed 95% of the normal food intake1-3 days, then slowly reduce it to 75% for two weeks, and then feed the normal food intake for two weeks and six months. This is an intermittent calorie restriction (ICR) diet.

At the same time, we should also pay attention to eat less and eat regularly, but the total feeding amount of a day should be determined according to the cat's own situation. In addition, we should exercise more, but the heart is not good and the joints are not good, so it is not easy for elderly cats to exercise too much.
