Over 40 fitness nutrition tips are essential for maintaining energy, strength, and progress in your training—especially when your metabolism isn’t what it used to be. If you’ve noticed that fat loss is harder, recovery takes longer, or your motivation fades faster than it did in your 20s, you’re not imagining things.
At Wired Fitness San Diego, we coach adults 40+ on how to adjust their fitness and fuel. What you eat—and when—has a huge impact on how you perform, recover, and feel day to day. Nutrition over 40 isn’t about cutting carbs or following fads. It’s about eating smarter, optimizing hormones, and choosing foods that actually support your body’s changing needs.
Whether you’re just starting your fitness journey or looking to improve your training results, these over 40 fitness nutrition tips can help you reduce inflammation, improve muscle retention, and feel sharper and more consistent. Most importantly, they’re simple, sustainable, and science-based.
Let’s break down the nutrition habits that will help you train harder, recover faster, and live better—without complicated diets or unnecessary restrictions.
