Beat the Summer Slump: Hydrate and Protein Up!
15 Jun
Summary
- Heat impacts appetite by slowing digestion and reducing hunger signals.
- Fluid loss increases nutrient demand and electrolytes are vital.
- Prioritize hydration and non-negotiable protein for summer energy.

During the summer months, physiological changes caused by heat affect appetite and digestion. Celebrity nutritionist Pooja Makhija highlights that increased fluid loss quietly raises nutrient demand, particularly for electrolytes. Concurrently, protein needs remain high, and inconsistent intake can lead to persistent fatigue and cravings.
Dr. Misba Begum, a clinical nutritionist, concurs that summer's heat causes the body to prioritize cooling, thereby reducing hunger signals. This, combined with increased sweating, can result in fatigue and a diminished appetite. High temperatures can also influence hormones regulating hunger and digestion.
Ignoring these changes can lead to detrimental consequences, such as substituting nutritious meals with sugary drinks or unhealthy snacks. This can cause fatigue, weakness, and poor concentration. Additionally, it may lead to weight gain and digestive issues. Failing to stay hydrated increases the risk of dehydration and heat-related illnesses.
To manage summer appetite changes, experts recommend consuming light, nutritionally balanced meals like fresh fruits, salads, and home-cooked options. Maintaining adequate hydration with water-rich foods such as watermelon and cucumber is vital. Eating small, healthy meals at regular intervals helps prevent fatigue and overeating, while limiting sugary beverages and fried foods is advised.
