As the new year approaches, many people resolve to improve their health and fitness. However, instead of turning to diet fads that promise quick results, it's important to focus on a sustainable approach based on basic nutrition principles. Trendy diets, from intermittent fasting to the carnivore diet and “detoxifying” juice cleanses, often sound too good to be true and can be misleading.
The Problem with Fad Diets
Many fad diets promote restrictive eating patterns, cutting out entire food groups or focusing heavily on one type of food. While some may offer temporary benefits, they often lead to feelings of deprivation, nutrient imbalances, or even eating disorders.
Nutrient Deficiency: Many trendy diets limit or eliminate essential nutrients. For example, a keto or carnivore diet may leave people deficient in fiber, vitamins, and minerals typically found in fruits, vegetables, and whole grains.
Sustainability: Fad diets may be difficult to maintain in the long run. The focus on restrictive eating or only allowing a set list of foods can feel unsustainable, leading people to give up and return to their old habits.
Yo-Yo Dieting: Many people experience the “yo-yo” effect-losing weight rapidly but regaining it quickly once the diet is over. These fluctuations can be harmful to metabolism due to the repeated loss of skeletal muscle mass followed by an increase in fat mass.

Mental and Emotional Health: Constant focus on dieting can interfere with a healthy relationship with food. Diet culture often promotes feelings of guilt or shame around eating, which can contribute to anxiety, depression, and even eating disorders in extreme cases.
The Key: Basic Nutrition
In contrast to these fad diets, the most effective and sustainable approach to health is grounded in basic, evidence-based nutrition principles. When you focus on nourishing your body with balanced, whole foods, the results tend to be more consistent and lasting.
Balanced Diet = Better Health: A balanced diet consists of a variety of whole foods from all food groups - including lean proteins, whole grains, fruits, vegetables, and healthy fats. This approach ensures you're getting a wide range of nutrients needed for overall health, including vitamins, minerals, fiber, and antioxidants.
Sustainability: Unlike fad diets that often focus on extreme restriction or elimination, basic nutrition allows for flexibility. It encourages moderation rather than deprivation, helping individuals make lasting, sustainable changes that fit their lifestyle.
Realistic and Enjoyable: Basic nutrition is centered on foods that people genuinely enjoy, making it easier to adhere to. When you enjoy the meals you're eating, you’re far more likely to stick with your healthy eating habits.

Long-Term Results: By focusing on nutrition rather than quick fixes, you're more likely to see lasting changes. The process is slower than fad diets, but it’s also more sustainable.
Practical Tips for a Sustainable Diet
- Eat Whole Foods: Prioritize fresh fruits, vegetables, whole grains, legumes, lean proteins, and healthy fats like avocado, nuts, and olive oil.
- Watch Portion Sizes: While it's important to focus on quality, portion sizes also matter. Aim for balanced portions to avoid overconsuming calorie-dense foods.
- Hydrate: Water is crucial for digestion, energy, and overall wellness.
- Mindful Eating: Pay attention to what you eat, savoring the flavors and textures of your meals.
- Listen to Your Body: Your body knows what it needs.
- Get Active: Healthy eating goes together with regular physical activity.
Setting SMART Goals
Losing weight doesn’t just happen; it requires a plan. The best plan includes SMART goals. According to Rachel Stahl Salzman, MS, RD, CDN, CDCES lecturer in medicine, Division of Endocrinology, Diabetes and Metabolism at Weill Cornell Medicine, SMART goals are not just for exercise and nutrition, but are helpful for creating personalized achievements in professional and personal lives as well.
SMART goals are:
- Specific: Write down exactly how many pounds you want to lose.
- Measurable: Instead of a general goal to eat better, have a specific plan to replace a bag of potato chips with a few carrot sticks, for example.
- Attainable: Losing one or two pounds a week is possible. According to the Centers for Disease Control and Prevention, this slow and steady weight loss is more likely to last.
- Realistic: You have too many responsibilities to exercise three hours a day. Choose your goal accordingly.
- Time-bound: Look at your calendar and determine a deadline for your weight-loss goal. Include small goals along the way for motivation. Once you meet your goal, reach higher and keep moving forward.
The Importance of Support
Losing weight or maintaining a healthy weight takes work. Doing it on your own may lead to giving up when things get tough. Instead, surround yourself with others who have similar goals to push each other toward your individual goals. A few places where you can find support include:
- Home: Having family support your efforts to lead a healthier life makes your journey smoother. Tell your family why you want to lose weight and how they can support you.
- Work: There are likely others at your job who want to lose weight. Connect with them for ongoing encouragement.
- Weill Cornell Medicine: From nutrition experts and physical therapists to our Comprehensive Weight Control Center, Weill Cornell Medicine provides customized support to help you achieve a healthier lifestyle.

By doing this, “you signal to yourself that this is an important undertaking, worthy of your time and effort.”
The Mediterranean Diet: A Lifestyle Choice
The Mediterranean diet is a lifestyle focused on healthy eating, physical activity, and enjoying meals. It is based on food that has been traditionally eaten in countries bordering the Mediterranean Sea and originated from Greek and Roman culture. The main dietary components are fruits, vegetables, whole grains, beans, legumes, seeds, and lean meat with extra virgin olive oil being a key ingredient throughout the diet. Research shows people who follow this lifestyle tend to live longer because of the many nutrients, vitamins, minerals, and omega-three fatty acids it provides.
What to Eat on the Mediterranean Diet
The Mediterranean Diet encourages you to eat plenty of some foods (like whole grains and vegetables) while limiting others. Here are some examples of foods to eat often:
- Lots of vegetables, fruit, beans, lentils and nuts.
- A good amount of whole grains, like whole-wheat bread and brown rice.
- Plenty of extra virgin olive oil (EVOO) as a source of healthy fat.
- A good amount of fish, especially fish rich in omega-3 fatty acids.
- A moderate amount of natural cheese and yogurt.
- Little or no red meat, choosing poultry, fish or beans instead of red meat.
- Little or no sweets, sugary drinks or butter.
- A moderate amount of wine with meals (but if you don’t already drink, don’t start).
Benefits of the Mediterranean Diet
The Mediterranean Diet has many benefits, including:
- Lowering your risk of cardiovascular disease, including a heart attack or stroke.
- Supporting a body weight that’s healthy for you.
- Supporting healthy blood sugar levels, blood pressure and cholesterol.

- Supporting a healthy balance of gut microbiota (bacteria and other microorganisms) in your digestive system.
- Lowering your risk for certain types of cancer.
- Slowing the decline of brain function as you age.
- Helping you live longer.
The Mediterranean Diet has these benefits because it:
- Limits saturated fat and trans fat.

General Tips for Weight Loss
- Set a realistic weight goal and timeline: Ask yourself what weight has felt comfortable for you before and if you can achieve that target without feeling overly deprived.
- Find a meal pattern that includes healthy foods that you enjoy eating: Both the Mediterranean diet and DASH meal plan include whole grains, vegetables, fruits, lean protein, and some dairy products.
- Manage portions of all foods: This allows you to include foods you enjoy in moderation.
- Set a goal of at least 150 minutes of aerobic activity per week: Aerobic exercises increase your breathing and heart rate, such as a brisk walk, bike ride, or swimming. Add in strength exercises two or more days per week. Strength training can increase your metabolism, which helps you burn more calories.
- Keep track of food intake and physical activity: Tracking helps to increase awareness of our eating and physical activity behaviors.
- Meal planning and food preparation: This helps ensure you have healthy meals and snacks available.
- Weight management programs: These programs offer support for your weight management journey. Be wary of programs that promise quick fixes. Long-term weight management is a journey that takes time.
Simple Food Swaps for Weight Loss
- Switch from a bowl of cold, dried cereal to one of hot whole-grain cereal and fruit to take in approximately 100 fewer calories each day. This one simple change to your daily diet could help you drop about 10 pounds in one year.
- Break out of the lettuce-and-tomato box for your salads. All kinds of veggies - and fruit - can go into your salad.
- Potatoes are a great food for helping you lose weight.
- Cocoa can be part of a healthy meal plan for weight loss.
- Fruits are fabulous weight-loss foods because they’re “big” foods, that is, foods that are bulked up by lots of fiber and water.
- Veggie burgers are a much better choice for your waistline and heart than ground meat. Veggie patties have only about half the calories of regular red meat patties and zero heart-hurting saturated fat.
- Four ears of corn has the same number of calories as one medium serving of French fries.
- Cooking up soba (the Japanese word for buckwheat) noodles instead of white-flour noodles is a great way to cut calories. A cup of soba has just 113 calories; a cup of white pasta, about 200.
- Open up a big bag of baby carrots and dip them into your freshly made no-oil-added, no-salt-added hummus.
The Importance of Fiber
Fiber is an important component of a weight loss plan. Over the counter psyllium is a great supplement that not only promotes a healthy microbiome and prevents constipation, but also gives the sensation of satiety (fullness). Psyllium also has secondary benefits such as lowering cholesterol and lowering blood glucose levels, as well as having anti-inflammatory properties. Additionally, some studies suggest decreased levels of colorectal cancer in patients taking psyllium. A natural high-fiber food that has many such associated health benefits is consuming two green kiwis daily.
Avoiding Common Pitfalls
People often overload themselves with goals when it comes to New Year’s resolutions and often get discouraged. Start with looking at your current schedule and activity/eating habits to see what small changes can be tweaked. Some great places to start are by drinking more water and less sugar-sweetened beverages and adding in activity, even if it is just 10 minutes each day.
According to Dr. Sarah Barenbaum, assistant professor of clinical medicine at Weill Cornell Medicine and assistant attending physician at NewYork-Presbyterian Hospital, it’s essential to be patient with the process and with yourself. “Trying to lose a lot of weight rapidly can be discouraging. Think of it as a marathon, not a sprint.”
