8 Science-Based Ways to Prevent Weight Gain After 40.

Prioritize Protein Intake  Protein helps preserve muscle mass, which naturally declines with age. Eating lean proteins like chicken, fish, tofu, and beans can boost metabolism and keep you feeling full longer.

Strength Training is Key  Lifting weights or doing resistance exercises helps build muscle, which burns more calories at rest. Aim for at least two strength training sessions per week.

Stay Hydrated  Drinking enough water helps regulate appetite and boosts metabolism. Sometimes, thirst is mistaken for hunger, leading to unnecessary snacking.

Eat More Fiber  High-fiber foods like fruits, vegetables, and whole grains improve digestion and keep you full, reducing overall calorie intake.

Get Quality Sleep  Poor sleep affects hormones that regulate hunger, leading to cravings and overeating. Aim for 7-9 hours of restful sleep each night.

Reduce Stress Levels  Chronic stress triggers cortisol production, which can lead to belly fat accumulation. Try meditation, yoga, or deep breathing exercises to manage stress.

Cut Back on Sugar and Processed Foods  Sugary and highly processed foods contribute to weight gain. Focus on whole, nutrient-dense foods instead.

Stay Active Throughout the Day  Regular movement, like walking, stretching, or even standing more, helps keep metabolism active. Avoid prolonged sitting whenever possible.
