Your Body Changes at 40
In your forties, metabolism slows and hormonal changes begin. You gain weight eating the same amount, recovery drags, and disease risk climbs. But with the right care, midlife can be healthy.
- •Basal metabolic rate: drops about 5% per decade
- •Muscle mass: falls about 1% a year after 30 (sarcopenia)
- •Bone density: drops sharply in women after menopause
- •Recovery time: slower after exercise or drinking
Diet Priorities After 40
- •Enough protein: 1.2g+ per kg of body weight to preserve muscle
- •Calcium and vitamin D: essential for bone health
- •Omega-3: cardiovascular health and brain function
- •Fiber: gut health plus cholesterol control
- •Antioxidant foods: berries, leafy greens, tomatoes
From 40 on, food quality matters more than quantity. Cut processed foods and center your diet on whole foods.
Key Nutrients and Sources
- •Calcium: milk, cheese, fish eaten with bones, tofu
- •Vitamin D: salmon, mackerel, egg yolk, sunlight
- •Magnesium: nuts, spinach, avocado
- •Vitamin B12: meat, fish, dairy (absorption declines with age)

Exercise After 40
Cardio alone isn't enough. Strength training is essential.
- •Strength training: 2–3 times a week, hitting the major muscle groups
- •Cardio: 150 minutes a week for heart health
- •Flexibility work: 10 minutes of stretching daily
- •Balance work: fall prevention (single-leg stands, etc.)
- •Joint-friendly options: swimming, cycling, walking
Screening Checklist
- •Blood pressure, blood sugar, cholesterol: annually
- •Colonoscopy: from age 45, every 5–10 years
- •Gastroscopy: every 2 years
- •Breast cancer screening (women): every 2 years
- •Prostate check (men): from age 50
- •Bone density (women): around menopause
- •Eye exam: annually (presbyopia, glaucoma)
If you're starting a new sport after 40 or feel pain, don't push through — consult a specialist.
