Obesiry factors including small for gestational age SGA status at birth, formula rather than breast feeding in infancy, and early introduction of protein in infant's dietary intake have been reportedly associated with weight gain that can persist later in life 6 — 8. Recently during the EASL conference, academic researchers and industry partners presented novel interventions targeting different gut- liver axis levels that include intestinal content, intestinal microbiome, intestinal mucosa, and peritoneal cavity Dig Dis Sci.

  • Childhood obesity is a multisystem disease with potentially adverse consequences and several complications that require the attention of health professionals.

  • This energy imbalance can cause weight gain, and consequently obesity. Many studies have been conducted to examine whether these foods have contributed to the increase in childhood obesity.

  • In addition to the fact that genetic factors can modulate nutrient storage, nutrients are able to modulate gene expression 9. Indeed, the release of fatty acids by the hydrolysis of white adipose tissue triglyceride stores allows us to face periods of food shortage or increased energy expenses.

1. Introduction

Lifestyle behaviors in children and pathophysiology of pediatric obesity are influenced by many sectors of our society, including the family Figure 1 3 Obesity is related to a clinical spectrum of liver abnormalities such as NAFLD ; the most important cause of liver disease in children — In adolescents, psychological outcomes associated with obesity are multifactorial and have a bidirectional relationship Figure 4.

  • In one case, a leptin-deficient child has been treated by leptin replacement. As stated above, energy storage in the form of fat is an important adaptation for survival.

  • Mealtime structure is important with evidence suggesting that families who eat together consume more healthy foods. Though many studies have shown weight gain with regular consumption of fast food, it is difficult to establish a causal relationship between fast food and obesity.

  • Disordered eating attitudes and behaviors in overweight youth.
