The time it takes to notice improvements on the Paleo diet varies greatly among individuals. Short-term effects, often felt within days to a week, can include increased energy, initial weight loss (primarily water weight), and improved digestion. Over weeks to months, further benefits like continued weight loss, better blood sugar regulation, enhanced mental clarity, and reduced inflammation may become evident. Long-term adherence, spanning months to years, can lead to sustained weight management, improved cardiovascular health, stronger immune function, and overall enhanced physical and mental well-being. However, these timelines are highly individual and depend on factors such as personal health status, diet adherence, metabolism, and lifestyle.
