it is possible to lose weight without exercising, although physical activity can significantly aid in the weight loss process. Weight loss primarily relies on creating a calorie deficit, which means consuming fewer calories than your body needs to maintain its current weight. You can achieve this deficit through dietary changes alone, such as reducing portion sizes, choosing nutrient-dense foods, and monitoring calorie intake. However, incorporating regular exercise can enhance weight loss efforts, improve overall health, and increase muscle mass, which in turn boosts metabolism and aids in weight management.
