This study aims to determine the relationship of macronutrient intake such as energy, carbohydrates, protein, and fat with the incidence of wasting in toddlers aged 24-59 months in the Pekkabata Health Center working area. This study used a case control approach, with purposive sampling technique, the number of samples used was 130 respondents
where the case sample was 65 respondents and the control sample was 65 respondents. Data collection used a 24-hour food recall questionnaire and anthroometric measurements. Data were analyzed using kruskal wallis test with sig value <0.05. The results showed that there was a relationship between energy intake and undernutrition status in toddlers in the Pekkabata Health Center working area with a significant value of P value = 0.000. There is a relationship between carbohydrate intake and the incidence of malnutrition in toddlers in the Pekkabata Health Center working area with a significance result of P value =
0.011. There is a relationship between protein intake and undernutrition status in children under five years old in the Pekkabata Health Center working area with a significant P value = 0.000. There is a relationship between fat intake and undernutrition status in toddlers.
