The latest study from the US has shown that there is a link between high-fat diet and heavy drinking. The researchers claimed that weight gain and heavy drinking are behaviourally linked because both these habits use the same neurocircuitry.
Several studies have proven how even moderate alcohol consumption can be bad for your health. Here is what a high-fat diet could do to your body:

It is bad for your brain: A 2015 study published in the journal Brain, Behaviour, and Immunity says that a high-fat diet can make the active immune cells in our brain to become sedentary. This could lead to and quicken cognitive impairment.

It could steal your sense of smell: A Florida State University study said that a high fat could cause you to lose your sense of smell. This was because foods high in fat were causing major structural and functional changes in the olfactory system, affecting the sense of smell.

Could cause anxiety and depression: A high-fat diet could alter your behaviour, increase anxiety and depression risk and impair memory. This kind of diet could also cause inflammation in the brain which could lead to such mental health concerns.

It could lead to sepsis: A more recent study showed that a high-fat diet could lead to an increase in chronic inflammation and sepsis severity which could lead to shock and organ failure.

It could make the offspring obese: Consumption of high-fat foods during pregnancy could lead to obesity in mothers which could put the offspring at a higher risk for lifelong obesity and related metabolic disorders in the future.

It could worsen the health of the elderly: A 2019 study established that elderly people on a high-fat diet rich in Omega-6 fatty acids could be at risk of developing diabetes and heart failure. The study elaborated how a diet rich in calories could cause a disruption in the gut composition and hence lead to inflammation, one of the major reasons for heart diseases.

It could cause sleep apnea: It was found that men who consumed diets high in fat were likely to experience sleeping problems at night including sleep apnea because they were more likely to feel sleepy during the day. Day time sleepiness was also associated with less energy during the day and more consumption of high-fat food which could again lead to sleep problems at night.
