Pre and Postnatal life 

Events in pregnancy and early life build food relationships. Studies suggest stress and poor maternal nutrition during pregnancy and infancy lead to lifelong opposing effects on the metabolism of food in the body. The metabolic status of the mother during pregnancy influences the brain functioning of the fetus. Early life experience has a major impact on early childhood food experiences.

Tips: Maintain a physically, nutritionally, mentally and emotionally adequate pregnancy and infancy. In case of any kind of stress, take help from the expert and rectify the issue as early as possible. During weaning introduce one food at a time and take guidance from a paediatrician rather than experimenting and following unauthentic viral tips.

Early life experiences

As per reports, initial life stressful memories affect food choices and also cause weight gain in adulthood. Any kind of stress in early life is a concern because it can have programming effects that intensify imbalanced responsiveness and handling of stress in adult life, contributing to mindless eating. Small modest differences in food intake or food choices in early life have lifelong consequences.

During childhood foundation of habits and preferences is made. At this phase, imitative and impulsive behaviour dominates, making children vulnerable to peer pressure. Positive or negative food habits, once made, shape the preferences and future choices of food throughout life.

Tips: Expose children to a variety of tastes including salty, sweet, sour, bitter and tasteless foods. Offer them a variety of food options but only one at a time. Counsel them regarding unhealthy food advertisements, junk foods and their long-term disadvantages. Motivate them not to indulge in distractions, especially virtual while eating. Guide them to enjoy their food and its mouthfeel, interact with them while eating and make their meal time a fun family time rather than a life struggling event.

Emotional indulgence

These have a significant role, mostly influenced by how product information is presented. At the point of purchase, several decision instincts and biases hinder rational decision behaviour. Product endorsement, done by the favourite public figures results in overvaluing the product benefit and false assumptions. This leads to an overestimation of self-control capacity and underestimating of the health risks associated with the choices made.

Tips: Get educated about the real health value of the food item and not get carried away by the marketing gimmicks.

Sensory Characteristics of food

The sight, smell and memory and expectation of food rule dietary choices. Uncontrollable attention is drawn by attractive high-caloric food cues, promoting greater food intake. The sight of appetizing food modulates brain activity in consistent ways. Viewing food items enhances the activation of visually related and reward-linked brain regions.

Tips: Always dig into finding out the nutritious side of food and decide whether it is going to be healthy in long term.

Affordability, availability and accessibility

While searching for food, the presence of many alternatives causes confusion and an inability to take optimal decisions. The pursuit of pleasure is the important driver of food decisions which overrules a balanced need-based mindset. Food selection and intake involve a complex involvement of higher brain functions including memory, learning and evaluation of different options.

Tips: Do not perceive food and its cost as a status symbol. Eat simple, easy to prepare and digest food options. Stop getting affected by unhealthy lucrative food displays and pictures.


It is a feature of modern life. Some people eat less when stressed, but most eat more thus if stress becomes chronic, then eating patterns become a coping strategy.

Tips: Learn to handle stress calmly and peacefully. Never use food as a stress-busting option. Consult an expert and manage stress as the top priority.


This causes an alteration in food intake, and this can result in a vicious circle of weight gain and depression progression.

Tips: Understand symptoms, internal feelings and emotions. Take help from a health guide and get cured in place of suffering ignorantly.

Physiological mechanisms of appetite control

Dietary decisions are regulated by circulating metabolic hormones, including those that signal to the brain about food intake and appetitive behaviours.
