16 Celebrity Secrets to a Flat Belly After 40

Hitting 40 often signals a new chapter in your fitness journey. Metabolisms slow, muscle mass can diminish, and abdominal fat is often stubborn to lose. Yet, many celebrities over 40 manage to maintain toned abs and sleek silhouettes. What are their secrets? We consulted celebrity trainers and dietitians to break down the tried-and-true strategies used by 16 Hollywood stars — no fad fixes, just practical, expert-approved tips to flatten your belly and boost your confidence.

Cher: Make Consistency Your Superpower

At 73, Cher embodies vibrant longevity and incredible strength. Her commitment? She works out five days a week — treating each session like an unmissable appointment. “Schedule your workouts as you would a meeting or doctor’s appointment,” says celebrity trainer Tadeo Arnold. As we age, sustaining a regular routine becomes increasingly vital; even if energy dips, making movement non-negotiable helps maintain muscle and keep belly fat at bay.

Cher’s approach to fitness demonstrates that age is just a number.

Gwen Stefani: Harness the Power of TRX

Gwen Stefani, 50, hasn’t just maintained her iconic abs — she’s made them stronger by embracing the TRX suspension trainer. This form of resistance training uses your body weight to sculpt the core, arms, and lower body. According to celebrity trainer Joey Maglara, integrating a total-body training regimen with a TRX sling accelerates belly-fat reduction and promotes balanced muscle tone.

  • TRX exercises increase core engagement and improve muscular balance.
  • Pairing TRX moves with cardio maximizes fat burning, leading to a tighter midsection.

Penelope Cruz: Adopt an Anti-inflammatory Diet

Spanish star Penelope Cruz, 45, follows the anti-inflammatory diet — rich in vegetables, fruits, whole grains, healthy fats, and lean protein, while limiting sugar and refined grains. Managing inflammation is key: according to Maglara, processed sugars and grains fuel systemic inflammation, which sabotages fat loss, specifically in the belly.

  • Swap white bread, crackers, and sugary drinks for leafy greens, berries, quinoa, olive oil, and wild-caught fish.
  • Lowering inflammation allows hormonal pathways for fat loss to function optimally.

Alison Sweeney: Activate Your Core Anywhere

Host Alison Sweeney, 43, swears by portable, simple moves. She relies on an eight-move core routine you can do while sitting, emphasizing that everyday ab engagement is crucial. Celebrity trainer Astrid Swan suggests: “Your core should be working even when you are not working out.” Consciously bracing your abs when standing, lifting groceries, or even opening doors boosts muscular endurance and definition.

  • Practice core engagement anytime, anywhere — even at your desk or in your car.
  • Regular core activation supports posture and back health, reducing injury risk.

Sofia Vergara: Don’t Skip the Weights

At 47, Sofia Vergara prioritizes strength training over spot-toning. Her Instagram is filled with clips of deadlifts, kettlebell swings, and other compound lifts. Swan notes these movements recruit the entire body, forcing your core to stabilize heavy loads, which torches calories and flattens your belly faster than endless crunches.

  • Weight training increases lean muscle, which revs up metabolism around the clock.
  • Deadlifts and kettlebell swings particularly challenge the abdominal wall for stability.

Gwyneth Paltrow: Support Gut Health with Probiotics

Wellness advocate Gwyneth Paltrow, 47, is a noted fan of probiotics and fermented foods like kombucha. As hormone levels shift in your 40s and beyond, digestive issues and bloating become more common. Nutritionist Serena Poon recommends a daily probiotic and increased intake of fermented foods to nurture a healthy microbiome, making it easier to maintain a flat, happy belly.

  • Include probiotic-rich foods: Greek yogurt, kimchi, sauerkraut, kefir.
  • Monitor sugar intake; excess sugar disrupts healthy gut bacteria balance.

Angela Bassett: Embrace High-Intensity Circuits

Angela Bassett is famed for her defined arms and abs, which she credits to high-intensity interval training (HIIT). This style alternates bursts of intense exercise with brief recovery. Trainers suggest HIIT is effective for burning visceral belly fat and boosting cardiovascular health.

  • Include 20-30 minute HIIT sessions, 2-3 times a week.
  • Focus on compound exercises like squats, lunges, push-ups, and mountain climbers.

Halle Berry: Mix Up Your Cardio

Halle Berry, over 50 and still a fitness icon, regularly switches her cardio routine with MMA, boxing, and sprints. Trainers agree: varying cardio exercises keeps your metabolism guessing and prevents fitness plateaus, which is especially important after 40.

  • Alternate between steady-state (long walks, jogging) and interval training (sprints, cycling bursts).
  • Try new modalities like dance classes, swimming, or kickboxing for variety and fun.

Jennifer Lopez: Prioritize Sleep and Stress Reduction

For Jennifer Lopez, looking and feeling her best at 50 goes beyond workouts. Her secret weapon: consistent, quality sleep and mindfulness. Chronic stress and sleep debt increase cortisol levels, which are linked to stubborn abdominal fat.

Explore expert strategies tailored for those over 50 in our guide, 21 Expert-Approved Ways to Lose Weight After 50. These actionable tips can help you tackle weight loss effectively and improve your well-being as you age.
  • Aim for 7-9 hours of quality sleep per night.
  • Incorporate deep breathing, meditation, or yoga to manage stress levels.

Salma Hayek: Never Skip Breakfast

Salma Hayek keeps her metabolism humming by never skipping breakfast and opting for protein-rich, balanced meals to curb cravings throughout the day. Nutritionists highlight that eating a nutritious breakfast can regulate insulin and prevent overeating, aiding in fat loss.

  • Start your morning with eggs, oatmeal, Greek yogurt, or a smoothie with berries and nut butter.
  • Balance carbohydrates with high-quality proteins and healthy fats for satiety.

Sheryl Crow: Go Plant-Based Most Meals

At 57, Sheryl Crow favors a plant-forward approach, focusing her meals on vegetables, beans, and whole grains with occasional lean meats. Dietitians agree: plant-based eating is linked with reduced inflammation and easier weight management.

  • Fill half your plate with vegetables at lunch and dinner.
  • Swap animal proteins for chickpeas, lentils, or tofu a few times a week.

Bethenny Frankel: Mindful Eating and Portion Control

Bethenny Frankel, 48, attributes her flat belly to mindful eating. She focuses on hunger cues, eats without distractions, and enjoys all foods in moderation — no restrictive dieting. Experts confirm that tuning in to your body’s needs and practicing portion control fosters long-term fat loss.

  • Eat slowly and pause between bites to monitor fullness.
  • Use smaller plates and bowls to encourage modest portions without feeling deprived.

Cameron Diaz: Drink More Water

Cameron Diaz, 46, always carries a water bottle and sips throughout the day. Staying hydrated aids digestion, flushes toxins, and can help prevent the “puffy belly” look. Nutritionists recommend drinking water before meals to control appetite and support metabolism.

  • Aim for at least 8 cups (2 liters) of water daily, more with activity or heat.
  • Limit sugary beverages and sodas, which can add empty calories and bloat.

Julianne Moore: Choose Whole Foods, Skip Processed Snacks

For Julianne Moore, 58, the key is sticking to whole, minimally processed foods — loads of veggies, fruits, and simple proteins. She avoids packaged snacks and fast food, helping to stabilize blood sugar and prevent fat storage around the waistline.

  • Keep healthy snacks like sliced vegetables, nuts, and fruit on hand.
  • Read ingredient labels and steer clear of added sugars and artificial additives.

Naomi Watts: Move Every Day

Naomi Watts champions consistency with daily activity, whether formal workouts or leisurely walks. She listens to her body and varies routines, embracing yoga, Pilates, cycling, and hiking.

  • Try to incorporate at least 30 minutes of movement daily, mixing strength, cardio, and flexibility-rich modalities.
  • Remember, movement doesn’t have to mean “exercise” — gardening, dancing, and playing with pets all count!

Sandra Bullock: Focus on Functional Fitness

At 55, Sandra Bullock keeps her core strong with functional fitness — movements that support daily life, such as squats, lunges, chopping motions, and balance work. Trainers say functional training builds the core from every angle and keeps workouts fresh.

  • Incorporate balance and coordination drills like single-leg stands, wood chops, and medicine ball tosses.
  • Functional moves also reduce injury risk and improve posture.
