Real talk from a 40-year-old finally getting serious about health + 13 expert nutrition tips for starting your wellness journey in your 40s.
I’ll be honest with you all. I’ve been saying I’d get serious about my health “someday” for about two decades. You know how it goes. Life gets busy, work takes over, and suddenly you’re staring down 41 wondering where the hell your metabolism went.
My journey actually started back in September 2023 after what I’ll diplomatically call “an incident” that made me realize I needed to move my body more than just from my desk to the kitchen for another snack or soda.
I joined the YMCA and started dabbling in fitness classes, but let’s be real: I was dabbling, not diving.
Then came the week of July 4th, 2025. Another “incident” occurred. Hopefully I will find the courage to share what these incidents were some day.
But needless to say, something just clicked as I thought about everything that had transpired over not just the last two years, but yeah – the last two decades.
Maybe it was the realization that my 41st birthday was a month away, or maybe it was finally accepting that my body isn’t going to magically fix itself while I sleep.
So I did what any reasonable person would do: I took 19 fitness classes in one week. Yep, you read that right. NINETEEN. My previous record was 5 classes in an entire week, so this was… ambitious, to put it mildly.
Was I sore? Absolutely. Did I question my sanity? Daily. But something amazing happened – I started craving more movement instead of dreading it.
For my birthday this year, instead of wanting a fancy dinner or spa day, I even told my husband I wanted to get my butt kicked by my instructor Rhonda Goode all day long. (Trust me, this is NOT normal Ashley behavior.)
Why I Asked the Experts About Fitness After 40
While I was busy shocking myself with my newfound fitness enthusiasm, I thought about the fact that exercise is only half the equation. If I’m finally serious about this whole health thing, perhaps I need to get my nutrition game together too.
So like the good little content creator I am, I reached out to 13 nutrition and fitness experts and asked them the question that’s been keeping me up at night: “What’s the best nutrition advice for someone in their 40s who is finally getting serious about their health?”
Their answers were eye-opening, practical, and honestly, a bit overwhelming. But here’s what they had to say…
13 Nutrition Tips for 40-Somethings Starting Their Wellness Journey to Consder
Foundational Nutrition Tips for Your 40s Reset
Foundational Nutrition Tips for Your 40s Health Reset
In your 40s, eat a balanced, whole food diet that supports muscle, hormone balance, and metabolism. Focus on lean proteins, high fiber vegetables, and complex, healthy fats and carbs for long-term energy and fuller feeling.
Hydration becomes more important for the digestive system, for the skin, and for the joints – you should drink at least 2 liters of water a day. Cap off processed foods and sweet admiration sugar, as they can hinder and impact long-term goals of wellness.
Last of all, consistency beats perfection. Develop habits you can keep—like meal prepping, mindful eating, and learning to listen to your body’s hunger decibel levels—that provide a solid direction for lifelong health.

Protein-Rich Diet Fuels Strength in Your 40s
The best nutrition advice for someone in their 40s starting their wellness journey is to sustain a healthy diet rich in protein, fiber, and hydration. During this stage of life, muscle mass starts to decline, metabolism halts, and energy as well as weight can be affected due to hormonal shifts.
Pay particular attention to whole foods: lean proteins (chicken, fish, and legumes), high fiber vegetables, and complex carbohydrates. Ultra-processed foods and extreme diets should be avoided. There is far greater benefit from small, sustainable habits like drinking plenty of water, eating balanced meals, and planning compared to trendy, untested short cuts.
Most importantly, view nutrition as fuel, not punishment. Your 40s should be focused on building strength and fostering longevity, not chasing after quick fixes.

Mediterranean Diet Powers Midlife Fitness Journey
As someone who’s been into biking and fitness for years from my youth to today, I’ve had to switch up my diet quite a few times to suit my body at different ages.
For people in their 40s and over, my primary advice would be to try adopting a Mediterranean-style eating pattern. Whole plant foods, lean proteins like fish and eggs, healthy fats like olive oil and curbing red meat and sugar intake do wonders to lower risks of heart diseases, diabetes and general cognitive decline while maintaining your energy levels.
Prioritize protein intake throughout your daily meals, aiming for at least 0.8-1g of protein per kilogram of body weight. Stick to lean protein sources like fish, chicken, eggs, dairy, tofu and Greek yogurt. This will ensure muscular upkeep and stability while prioritizing your metabolism and resilience to aging.
Eat anti-inflammatory foods like berries, nuts and leafy greens, as these protect against oxidative stress. Ensure you consume about 1000mg of calcium, which you can get from food like dairy and leafy greens, and at least 300-800IU of Vitamin D every day as these would keep your bones and immune system healthy. Omega-3s also aid your heart greatly.

Return to Nature for Optimal Wellness Success
The best nutrition advice I would give to someone in their 40s who is finally getting serious about their health and wellness journey is… GO BACK TO NATURE.
When it comes to food, try to choose foods in their most organic natural states. The less processed foods you consume, the more nutrients you’ll take in.
When it comes to wellness, try to incorporate exercise that exposes you most to nature. Examples of this include: going for a walk outside, getting sun on your face and allowing yourself to sweat/detox.
To me, getting more in touch with nature is the ultimate way to heal, recover and rejuvenate on a wellness journey. Once you take those simple steps, you’ll be happy you started and even more eager to continue on.
Here’s to optimal wellness at any age!

Whole Foods Protect Oral Health in Midlife
At your 40s, what you eat will especially determine your mouth’s condition. Eat whole foods such as vegetables, lean protein, and healthy fats, and floss every day to keep your teeth safe. Processed and sugary foods are not just causative agents of weight gain; these foods are one of the main sources of cavities and gum disease.
When bone density is decreased, your body will need more calcium and vitamin D to support teeth and jawbone health. Leafy greens, milk, and plant milks that are fortified are excellent sources. Good oral hygiene also plays a critical role in a healthy mouth. Drink plenty to allow your body to naturally produce saliva to shield you from cavities and to promote your digestive system to run as well as it can.
Limit food and beverages that are acidic, like wine, citrus fruits, and soda, which gradually wear down enamel. When using or consuming them, spit them out and don’t brush at least 30 minutes afterward so that you won’t continue to wear down your enamel.
Most importantly, accept it as a lifestyle change year after year. Nutrition influences everything about your body, your teeth included. I suggest that you schedule medical and dental wellness visits on a periodic basis so that you can stay in tune and informed.

Balance and Moderation Drive Vibrant Midlife Health
If you are in your 40s, with an emphasis on a balanced diet, the impact could be significant. You can still eat a mix of fruits, veggies, lean proteins and healthy grains without deprivation — just be sure to moderate and keep an eye on your portion sizes. And don’t forget to hydrate, drinking plenty of water all day long. The ability to hear what your body is telling you and then nourish it properly, which is what it truly needs during this phase, are the keys to keeping you healthy and vibrant. Incremental small steps, not giant leaps, and progress not perfection, are the goals to set.

Simplify Diet for Mental and Physical Vitality
In your 40s, health is not about appearance, it’s about the life you desire. Diet is a matter of respect for yourself. Your body fed on good foods has the vitality to be present, nurture others, and navigate the vagaries of contemporary life with greater ease.
Instead of doing a complete overhaul in your diet, begin with simplification. Opt for whole foods. Include sufficient protein. Cut added sugar. These simple steps favor your metabolism, mental acuteness, and emotional stability.
At Manhattan Mental Health Counseling, we observe each day how diet affects mental health. Well-fed clients tend to be more emotionally strong and better prepared to do therapeutic work.
Your health journey should stem from self-trust. Allow food to be a part of taking care of yourself, not controlling yourself.

Strategic Eating Boosts Energy for Active Travelers
Active travelers, who stick to regular meal times during long walks towards fitness, benefit from higher energy levels even during all-day cultural explorations. On our private walking tours in Prague we noted that energetic travelers who enjoyed hearty breakfasts the morning of their excursions and tucked away local power-packed snacks, like traditional pastries and well aged salamis, sustained visit-highs for neighborhood walkabouts that lasted the whole day—and contributed to their overall health plans.
Compared to others who let their health subsist on coffees or tourist-vibe fast bites, they tended to crash in the afternoon when energy waned, impacting their fitness goals and traversing culture agenda had in store for the night.
Today, our guides build in real, local nutrition, while walking, into their itineraries — from family-run bakeries to traditional markets, local spots that understand what it takes to keep wellness-focused travelers energized. “These collaborations give you access to tradition (whether Czech bread recipes, artisanal preserves, or charcuterie), which not only feeds imperative endurance, but becomes a cultural immersion.” Whether you’re learning about Czech bread-making or tasting homemade jam, these experiences are central to the walking adventure, harnessing fitness and cultural exploration.
Before you travel to pedestrian-friendly places, do some research on local food cultures that match your wellness goals as well and encourage you to keep on walking. Interact with trail angels familiar with the physical and nutrition aspects of hiking and learn about local health-conscious gems that will maximize your energy without hijacking your wellness experience. Although traditional, healthy backup snacks should still be used., you should also consider local – many local walking foods, created for long distance walking, in actual fact beat processed varieties in maintaining energy levels for longer and consequently helping boost your snacks while they are at it.

Colorful Plant Foods Transform Midlife Health Daily
The best nutrition advice I would give to someone in their 40s who is prioritizing health is to focus on eating whole plant foods every day. I recommend eating a variety of fruits and vegetables. Aim for a few servings of each daily, gradually increasing to 5-10 servings per day. Try to get a variety of different produce throughout the week to maximize your nutrients and antioxidants. The more colorful the food the better. Include beans or lentils daily. They provide a great source of plant protein and fiber and are healthier than meat and chicken. You can add them to salads or swap them out in your favorite dishes like pasta and stir-fry’s.
Enjoy a handful of nuts or seeds or a spoonful of nut butter. Choose options that are without added sugars and oils. They provide healthy fats, protein, and are satiating. Include a serving of whole grains daily. Options include brown rice, rolled or steel cut oats, quinoa, barley, farro, whole grain bread, and whole grain pasta. Limit added sugars and try to keep below 25g per day to improve metabolic health and prevent excess weight gain. I recommend limiting sodium and try to stay under 1500mg per day to avoid elevated blood pressure. Reduce saturated fats from animal products and processed foods and instead focus on healthy fats from plants like nuts and seeds. Small steady changes can add up to significant health benefits.

Embrace Strategic Imperfection for Wellness Success
The best nutrition advice I would give to someone in their 40s who is finally getting serious about their health and wellness journey? I’d say “bring me your best B game!” Yup, you heard it right. Leave your A game for the office or other areas of your life. When it comes to wellness, forget perfection — it’s not the goal, and it’s often the thing holding you back and sabotaging your efforts. In my Heal Thru Food online community, I coach high-achieving professionals to embrace what I call “strategic imperfection” — an approach that ditches the all-or-nothing mindset and focuses instead on small, consistent wins that add up to real transformation.
Happy to share more if you’re interested. Thanks for your consideration!

Small, Sustainable Steps Lead to Lasting Change
Be patient and focus on small, sustainable changes to get started. I often tell the clients I work with: think of your goal as being at the top of the staircase. In order to get to the top, we need to take one step at a time. When we were younger we may have gotten away with skipping over a few steps, but that doesn’t work as well now as it used too.

Rainbow Foods Build Strength in Your 40s
As a registered nutritionist, I would recommend that people in their 40s consume good food, which can help them have more energy, build muscles, and avoid health problems. Eat nutritious, presumably complete foods to accommodate the evolution of your body.
1. Eat the Reality of Foods
Eat your plate full of highly colorful foods (think all different colors of the rainbow), fill with lean proteins (chicken, fish, beans), whole grains (oats, quinoa) and healthy fats (avocados, nuts, olive oil). The foods are rich in vitamins, minerals, and fiber that make you tough and energetic.
2. Eat More Protein & Healthy Fats
In that case, protein contributes to maintaining muscle, which naturally deteriorates in the course of aging. Add fish, eggs, lentils and nuts. Good fats (such as salmon and seeds) take care of the heart muscles and the brain.
3. Support the Health of Bones
Dairy, as a source of calcium and leafy green vegetables are important sources of calcium since bone density begins to decline. Vitamin D (sunlight, eggs, fatty fish) is also important. Take supplements (as recommended by the physician) when required.
4. Fiber is Your Friend
Fiber (which is in whole grains, fruits and veggies) helps you digest, regulates your blood sugar, and makes you feel full. It also assists in weight control and the suppression of cravings.
5. Limit Processed Foods & Sugars
Reduce consumption of sugary foods and drinks, processed foods and processed drinks. They create health hazards and give rise to inflammation. Instead, go with whole-food snacks such as nuts or fruit.
6. Stay Hydrated
Take lots of water to boost metabolism and energy. Stay away from or minimize alcohol and caffeine which are dehydrators.
7. Eat Mindfully
It is necessary to avoid skipping meals that may trigger overeating. Notice warning signs of hunger, and eat with intention.
8. Nutrition and workout together
Strength exercises allow for the preservation of muscle and metabolism. A healthy lifestyle is also part of living, which is achieved through cardio exercises and proper sleep.
The difference comes in small but frequent differences. To find out more information specific to you, visit a dietitian or a health coach. Why not begin? Tell me, do you want to have an easy meal plan?

Protein and Strength Training Combat Muscle Loss
Dial in your protein and pick up something heavier than a coffee mug. Most people in their 40s lose 1-2 % of lean muscle per year, which slows metabolism and drives insulin resistance. Aim for a minimum of 1.2 grams of protein per kilogram of body-weight daily (spread over three meals) and layer in full-body strength training two to three times a week. The protein supplies the amino acids your muscles need to rebuild and the lifting sends the signal to do it. Together they preserve (or add) calorie-burning muscle, stabilize blood sugar, and protect bones and joints so you head into your 50s with more energy.

It’s Never Too Late to Start (Even When You’re Staring Down 41)
After talking to these experts and living through the most physically challenging (and surprisingly exhilarating) few weeks of my adult life, here’s what I’ve learned:
Perfect is the enemy of good. As Missy Lapine said, bring your “B game” to wellness. I spent years waiting to start because I thought I needed to overhaul everything at once. Turns out, 19 fitness classes in a week might not be sustainable (shocking, I know), but it did break through my mental barriers about what I’m capable of.
Your body is more resilient than you think. I genuinely didn’t believe I could do half of what I’ve accomplished these past few weeks. If you’d told me six months ago that I’d be craving Pilates and asking for more Zumba for my birthday, I’d have checked you for a fever.
Small changes compound. Every expert emphasized this, and they’re right. I didn’t go from couch potato to fitness fanatic overnight (despite that one crazy week). The real progress happened in the 22 months of showing up imperfectly, trying different classes, and slowly building the habit.
Community matters. Finding Rhonda and her classes, having my husband as a workout buddy for aqua aerobics, even having that seasoned Zumba student tell me I should try a different class (bless her heart) – it all contributed to where I am now.
If you’re reading this and you’re in your 40s wondering if it’s too late to start taking your health seriously, let me save you some time: it’s not. Well, at least not yet. But time IS running out friend.
Whether you’re dealing with declining muscle mass, hormonal changes, or just the general wear and tear of life, your body is waiting for you to show up for it.
You don’t need to take 19 classes in a week (though it was exhilarating), but you do need to start somewhere.
Pick one piece of advice from these experts that resonates with you. Maybe it’s adding more protein to your breakfast or taking a 10-minute walk after dinner. Maybe it’s finally signing up for that fitness class you’ve been thinking about for months.
Whatever it is, start there. Don’t wait til 50 because by then, well it might be too late!
What’s your one small step going to be? I’d love to hear about it. Drop me a line or share your story. We’re all figuring this out together.
