Weight loss fundamentally boils down to creating a calorie deficit – burning more calories than you consume. While exercise can certainly help with this, it's not the only way. Diet plays a crucial role. Making mindful food choices and controlling portion sizes can significantly contribute to a calorie deficit. Additionally, lifestyle changes like being more active in your daily routine (think walking, using stairs, or standing more) also help. Remember, weight loss is about balance and sustainability, so find a routine that works for you, with or without a structured workout.
