What should you eat if you have obesity?

According to the World Health Organization, over 890 million adults globally were living with obesity in 2022, underscoring a significant health challenge. A primary aspect of managing this condition is adopting a healthier diet, so what should you eat if you have obesity to achieve and maintain a healthier weight?

Quick Summary

A diet focusing on whole foods like vegetables, fruits, whole grains, and lean protein is key for individuals with obesity. Limiting high-calorie processed foods, saturated fats, and sugary drinks is essential for creating a necessary calorie deficit and supporting weight loss efforts.

Key Points

• Emphasize whole foods: Fill your plate with nutrient-dense options like vegetables, fruits, whole grains, and lean proteins to feel full and support weight loss.

• Limit processed items: Cut back on high-calorie, low-nutrient processed foods, including sugary cereals, cakes, and packaged snacks.

• Stay hydrated with water: Replace sugary drinks and fruit juices with water to reduce calorie intake and help manage appetite.

• Control portions consciously: Use smaller plates and practice mindful eating to become more aware of how much you are consuming.

• Increase fiber intake: Incorporate high-fiber foods such as legumes and whole grains to boost satiety and improve digestion.

• Incorporate lean protein: Add sources like fish, eggs, and beans to meals to promote fullness and maintain muscle mass during weight loss.

The Foundation of a Healthy Diet for Obesity

The cornerstone of any effective weight management plan, particularly for those with obesity, is achieving a sustainable energy balance. This means consuming fewer calories than your body expends. A diet focused on nutrient-dense, low-energy-dense foods is key to feeling full and satisfied while reducing overall calorie intake. This approach not only helps with weight loss but also provides the essential vitamins and minerals your body needs.

Prioritizing Low-Energy-Dense Foods

Low-energy-dense foods contain fewer calories for their volume, helping you feel full without consuming excess energy. These foods are typically high in water and fiber, which take longer to digest. Incorporating them into meals is an excellent strategy for portion control.

Examples of low-energy-dense foods:

• Leafy greens and non-starchy vegetables like broccoli, spinach, and bell peppers
• Whole fruits such as berries, apples, and melons
• High-water-content foods like cucumbers and soups

The Importance of High-Fiber Foods

Dietary fiber, particularly soluble fiber, plays a crucial role in promoting fullness and aiding digestion. It absorbs water in your digestive system, forming a gel that slows down the movement of food, which helps reduce appetite.

Excellent sources of fiber include:

• Legumes (beans, peas, lentils)
• Whole grains (oats, brown rice, quinoa)
• Fruits and vegetables
• Nuts and seeds

Boosting Satiety with Lean Protein

Protein is a vital macronutrient for weight management because it increases the release of the hormone peptide YY, which decreases appetite and promotes feelings of fullness. A high-protein diet can also help preserve muscle mass during weight loss and boost your metabolism.

Good sources of lean protein include:

• Fish (salmon, tuna) and lean meats (chicken, turkey)
• Eggs and low-fat dairy products
• Plant-based proteins like beans, lentils, and tofu

What to Prioritize: Key Food Groups

By focusing on these food groups, individuals can build a balanced diet that supports weight loss and overall health.

Fruits and Vegetables

Aim for at least five portions of a variety of fruits and vegetables every day, as recommended by the World Health Organization. They are low in calories, high in fiber, and packed with vitamins and antioxidants.

• Use vegetables to fill up at least half of your plate.
• Snack on whole fruits instead of processed snacks.
• Opt for whole fruits over fruit juices, which are high in sugar and calories.

Whole Grains and Legumes

Swap refined carbohydrates for whole grains and legumes to increase your fiber intake and feel fuller for longer.

• Choose whole wheat bread and pasta over white varieties.
• Incorporate brown rice, quinoa, and oats into your meals.
• Add beans, lentils, and peas to soups, stews, and salads.

Healthy Fats

While fats are energy-dense, some are essential for health and satiety. The key is to consume them in moderation and choose healthy, unsaturated fats over saturated and trans fats.

• Use plant-based oils like olive or canola oil for cooking.
• Include nuts, seeds, and avocado in small portions.
• Eat oily fish like salmon, which provides omega-3 fatty acids.

Foods and Drinks to Avoid or Limit

Just as important as what to eat is what to cut back on. Limiting or eliminating certain foods can significantly reduce your calorie intake and improve your health markers.

Processed Foods and Refined Carbs

Many convenience foods, packaged snacks, and sweets are high in calories, sugar, and unhealthy fats but low in nutrients. These include items like sugary cereals, cakes, cookies, and white bread.

Sugary Beverages

Sodas, sweetened fruit juices, and energy drinks are major sources of excess calories and added sugars, which contribute to weight gain. Replacing them with water is a simple yet highly effective strategy for weight management.

Unhealthy Fats

Industrially-produced trans fats and excessive saturated fats found in foods like fried items, fatty meats, and many baked goods should be limited. They contribute to high cholesterol levels and heart disease.

Healthy Swaps for Obesity Management

Making small, strategic changes can have a big impact over time. Here is a comparison of healthier alternatives to common food choices:

Unhealthy Choice	Healthy Swap	Benefits of the Swap
White Bread	Whole-grain Bread	Higher in fiber, keeps you fuller longer
Sugary Soda	Water with lemon or herbal tea	Zero calories, better hydration, no added sugar
Fried Chicken	Baked or Grilled Chicken	Significantly lower in fat and calories
Creamy Pasta Sauce	Tomato-based or vegetable purée sauce	Lower in saturated fat and calories, can increase vegetable intake
Milk Chocolate	A small piece of dark chocolate or fresh berries	Higher in antioxidants, less sugar, and can help with cravings
High-sugar Cereal	Oatmeal topped with fruit and nuts	More fiber and protein to promote satiety
French Fries	Boiled or roasted potatoes	Lower energy density and fat content

Optimizing Your Eating Habits

Beyond what you eat, how and when you eat can make a big difference in managing obesity.

• Practice mindful eating: Pay attention to your food and hunger cues. Avoid eating in front of the TV or while distracted.
• Control your portions: Use smaller plates and measure ingredients to help manage calorie intake.
• Don't skip meals: Eating at regular intervals can help regulate energy levels and prevent overeating later in the day.
• Plan ahead: Preparing meals and snacks in advance can prevent impulsive, unhealthy choices.
• Stay hydrated: Drinking plenty of water can help you feel full and avoid confusing thirst with hunger.

Conclusion

Successfully managing obesity through diet is a holistic process that requires making sustainable lifestyle changes, not just following a restrictive short-term plan. By focusing on nutrient-dense foods like fruits, vegetables, whole grains, and lean proteins, and by reducing processed foods, sugary drinks, and unhealthy fats, individuals can work toward a healthier weight and reduce their risk for related conditions like heart disease and type 2 diabetes. Adopting mindful eating practices and focusing on portion control will further support these efforts for long-term health and well-being.
