The holiday season is here, and Thanksgiving often marks the beginning of celebrations focused on family, food, and gratitude. While it’s a time to enjoy yourself, it can also present challenges if you’re trying to stick with healthy habits. The good news is that you don’t have to choose between enjoying the holiday and maintaining your wellness goals. With a few thoughtful approaches, you can do both!

Stay Active with Family Fun

Thanksgiving traditions don’t have to be confined to the dinner table. Incorporate movement into your holiday plans by organizing family-based activities that get everyone outdoors. A short walk after the big meal can aid digestion and provide a chance to connect in a different setting. You might also consider starting a new tradition, like a family hike or a friendly game of touch football in the backyard. Not only does this add a layer of fun, but it also helps balance out the indulgence of the holiday meal.

Enjoying Food Without Guilt

Thanksgiving is about more than food—it’s about spending time with loved ones and creating lasting memories. The key to balancing enjoyment with health is mindful eating, which lets you savor your favorite dishes guilt-free. Mindful eating encourages you to slow down and truly appreciate each bite. Pay attention to the flavors, textures, and aromas of the food, and listen to your body’s hunger and fullness cues. Take smaller portions to start, and go back for seconds if you’re still hungry. By eating mindfully, you can fully enjoy your meal, indulge in your favorite foods, and still feel good about your choices. Remember, this is a time to celebrate and connect with family, so let food be part of that experience, not something to stress over.

Structuring Your Plate for Balance

One way to enjoy the feast while keeping balance in mind is by being strategic about how you fill your plate. Start by prioritizing vegetables and lean proteins, which help keep you satisfied longer. Roasted vegetables, green beans, and salads are excellent choices alongside turkey or other protein sources. Aim for a colorful plate, with about half filled with veggies, a quarter with protein, and the last quarter reserved for your favorite indulgent foods, like mashed potatoes, stuffing, or that slice of pie you’ve been looking forward to.

Thanksgiving is an opportunity to celebrate family and food, and with a few thoughtful choices, you can make the most of both. By staying active through family-friendly activities and building a balanced plate, you’ll leave the table feeling good—both physically and emotionally. After all, the real focus of the holiday should be on making memories, and that’s something you can’t put on a plate.

In the realm of fitness and nutrition, the term "caloric deficit" often takes center stage. But what exactly does it mean, and why would someone actively pursue it? Let's break it down.

A caloric deficit occurs when you consume fewer calories than your body expends in a day. It's commonly sought after for weight loss purposes, as it forces your body to tap into stored fat for energy, leading to shedding unwanted pounds. For individuals engaging in strength training,
cardio exercises, or participating in endurance events like marathons, maintaining a caloric
deficit might seem like the golden ticket to reaching their fitness goals.

However, here's the catch: while a caloric deficit can indeed lead to weight loss and improved
body composition, it's not sustainable or beneficial in the long term to always remain in this
state.

Why? Because our bodies are incredibly smart and adaptive machines. When faced with a
prolonged caloric deficit, they adjust their metabolism and hormone levels to conserve energy,
making weight loss plateau and potentially causing negative side effects such as fatigue, muscle
loss, and decreased performance in physical activities.

Moreover, for individuals who are already physically active, being in a constant caloric deficit
can hinder recovery and impair muscle growth. Strength training and intense cardio sessions
create a demand for additional calories to repair tissues, replenish glycogen stores, and support
overall recovery. Without an adequate supply of nutrients, the body struggles to repair and
rebuild, leading to stagnation in progress and increased risk of injury.

So, what's the solution? While periodic caloric deficits can be a useful tool for achieving weight
loss goals, it's essential to balance them with periods of maintenance or even surplus calories,
especially for those engaged in rigorous physical activity. Introducing more calories strategically
during times of increased training volume or intensity can support performance, enhance
recovery, and promote overall well-being.

In conclusion, while a caloric deficit has its time and place in a well-rounded fitness regimen, it's
crucial to recognize that it's not sustainable or beneficial for everyone to always remain in this
state. By understanding the importance of balance and periodically integrating more calories
when needed, individuals can optimize their performance, achieve their fitness goals, and
maintain a healthy relationship with food and exercise.

Summer is the perfect time to rejuvenate not only your spirit but also your diet. The warmer months bring an abundance of fresh produce, longer days, and a general sense of renewal, making it an ideal time to experiment with new nutritional habits. Here’s how you can make the most of summer by trying new things in your diet.

1. Explore Local Farmers' Markets – One of the best ways to dive into new nutritional habits is by visiting local farmers' markets. These markets offer a wide variety of fresh, seasonal produce that you might not find in regular grocery stores. Trying out new fruits and vegetables can help you incorporate different nutrients into your diet, enhance your meals with vibrant flavors, and support local agriculture.

• Try something unfamiliar: Pick up a fruit or vegetable you've never tried before, like starfruit, or purple carrots.
• Ask for advice: Farmers are often happy to share cooking tips and recipes for their produce.

2. Incorporate Plant-Based Meals – Summer is a fantastic time to incorporate more plant-based meals into your diet. With an abundance of fresh vegetables and fruits available, creating delicious, plant-based dishes can be easier and satisfying.

• Grilled Veggie Skewers: Combine colorful bell peppers, zucchini, cherry tomatoes, and mushrooms on skewers and grill them for a tasty, nutrient-packed meal.
• Smoothie Bowls: Blend frozen berries, bananas, and spinach with a splash of almond milk, and top with granola, chia seeds, and fresh fruit.

3. Hydrate with Natural Beverages – Staying hydrated is crucial during the hot summer months. Instead of reaching for sugary sodas or artificially flavored drinks, try hydrating with natural beverages.

• Infused Water: Add slices of cucumber, lemon, mint, or berries to a jug of water for a refreshing twist.
• Herbal Iced Teas: Brew herbal teas like hibiscus, peppermint, or chamomile and serve them chilled with a touch of honey or a squeeze of fresh citrus.

4. Experiment with Global Cuisines – Summer is a wonderful time to broaden your culinary horizons by exploring global cuisines. Many cultures emphasize fresh, seasonal ingredients and bold flavors, which can add excitement to your meals.

• Mediterranean Diet: Emphasize fruits, vegetables, whole grains, and healthy fats. Try dishes like Greek salads, hummus, and grilled fish.
• Asian-Inspired Meals: Incorporate stir fry, sushi, and noodle salads with plenty of fresh veggies and lean proteins.

5. Grow Your Own Produce – If you have space, consider starting a small garden. Growing your own herbs, fruits, and vegetables can be incredibly rewarding and ensures you have fresh, organic produce at your fingertips.

• Herb Garden: Even a small windowsill can support a thriving herb garden with basil, parsley, cilantro, and mint.
• Vegetable Patch: Tomatoes, cucumbers, and peppers are relatively easy to grow and do well in summer gardens.

6. Mindful Eating Outdoors – Take advantage of the beautiful weather by enjoying meals outside. Mindful eating, where you focus on the taste, texture, and experience of eating, can enhance your relationship with food and improve digestion.

• Picnics in the Park: Pack a healthy picnic with whole-grain sandwiches, fresh fruit, and vegetable sticks.
• Al Fresco Dining: Set up a dining area on your patio or balcony and enjoy meals with family and friends in the open air.

7. Make Healthy Frozen Treats - Beat the heat with homemade frozen treats that are both delicious and nutritious.

• Fruit Popsicles: Blend fresh fruit with a bit of juice or yogurt, pour into molds, and freeze.
• Frozen Yogurt Bites: Dollop a spoonful of yogurt on a baking sheet, top with berries and a drizzle of honey, and freeze for a quick, healthy snack.

Summer offers a unique opportunity to refresh your diet and embrace new nutritional habits. By exploring local markets, incorporating plant-based meals, hydrating with natural beverages, experimenting with global cuisines, growing your own produce, practicing mindful eating, and indulging in healthy frozen treats, you can enhance your overall health and enjoy the season to its fullest. So, step out of your comfort zone and make this summer a delicious and nutritious adventure!

Knowing the importance of exercise and maintaining a healthy lifestyle is always positive progress to becoming your best self, but getting your family and friends on board with this commitment can be a challenging task. If you want to encourage your loved ones to incorporate exercise into their daily routines, here are some tips and strategies to help you motivate them.

• Lead by example: Setting a positive example is the most powerful way to inspire others. Demonstrate your commitment to a healthy lifestyle by consistently engaging in exercise and making nutritious choices. They may be more inclined to follow suit after seeing your dedication to working on yourself and your lifestyle.
• Make it fun: Other people might see exercise as a chore; however, it can be an enjoyable activity. Encourage your family and friends to participate in activities they genuinely enjoy, whether it's dancing, hiking, playing a sport, or even trying out new fitness classes together. Fun makes fitness sustainable!
• Set realistic goals: Help your loved ones establish achievable fitness goals. Whether it’s running a certain distance, losing a specific amount of weight, or improving overall health, having clear objectives can motivate them to stay on track.
• Create a supportive environment: Foster an environment that encourages exercise. Create a home gym space, stock up on healthy snacks, and incorporate active outings into your social plans. Surrounding your loved ones with opportunities for fitness makes it more likely they'll join in.
• Educate and share information: Share articles, videos, and success stories related to fitness and its benefits. Knowledge can empower your loved ones to make informed decisions about their health. Offer to answer questions and provide guidance when needed.
• Be flexible: Recognize that everyone's fitness journey is unique. Be open to adapting to their preferences and schedules. Encourage them to find a routine that works for them rather than imposing your own.
• Hold each other accountable: Partner up with family and friends for workouts. Exercising together provides motivation because you're less likely to skip a session if someone is counting on you. Consider friendly fitness challenges or competitions to keep things interesting.
• Celebrate achievements and use incentives: Celebrate their milestones, no matter how small. Whether it's completing a week of consistent workouts or reaching a fitness goal, acknowledging their achievements reinforces their commitment. You can use incentives like a post-workout treat, a movie night, or a small reward for reaching specific goals to act as short-term motivators.

It’s important to always remember that the journey toward a healthier lifestyle is personal and unique for everyone. Your role is to provide support, encouragement, and a positive environment. Ultimately, the decision to embrace exercise and a healthier lifestyle lies with your loved ones, but your influence can be a powerful catalyst for positive change. By using these strategies, you can help them take those crucial first steps toward a happier, healthier life.

In today's fast-paced world, where new diet trends and health fads emerge almost daily, it can be challenging to discern what truly benefits our bodies. Amid this whirlwind of ever-changing advice, the key to a healthier life may not lie in exotic superfoods or rigorous diet regimens, but in the consistent practice of nutritional basics.

The Allure of Fads

It's easy to see why diet fads capture our attention. Promising quick results with minimal effort, they offer a seemingly easy solution to our health concerns. From juice cleanses to keto diets, these trends often revolve around drastic changes and exclusions, creating an illusion of instant improvement. However, such approaches can be unsustainable in the long term and may lead to nutritional imbalances.

Consistency in Basics: A Sustainable Approach

The cornerstone of good nutrition lies in consistency and balance. This means regularly consuming a variety of foods that provide the nutrients your body needs. Here are some fundamental practices.

• Balanced Diet: Incorporate a mix of carbohydrates, proteins, and fats in your meals. Carbohydrates found in fruits, vegetables, and whole grains provide energy. Proteins are essential for repair and growth, while healthy fats support brain health and hormone production.
• Hydration: Water is crucial for almost every bodily function. Staying adequately hydrated helps in digestion, nutrient absorption, and even skin health.
• Moderation: Enjoying your favorite foods is part of a healthy lifestyle, but moderation is key. It’s important to balance indulgences with nutrient-rich foods.
• Regular Meals: Skipping meals can lead to overeating later. Regular meals help maintain blood sugar levels and the feeling of fullness, aiding in better energy management and mood regulation.

The Long-Term Perspective

Adopting a consistent approach to the basics of nutrition may not offer the instant gratification that fads promise, but it paves the way for sustainable, long-term health benefits. By focusing on balanced and regular eating, hydration, and moderation, you can nourish your body and mind, keeping them strong and resilient against the allure of quick fixes.

In the end, the true “fad” may be the belief that there is a shortcut to health. True wellness comes from a consistent commitment to the simple, foundational principles of good nutrition.

It’s no secret that our emotions impact what we eat, when we eat, and how much we eat. In fact, sometimes it seems that the strongest cravings hit when our emotional and mental well-being is at its weakest. Emotional eating is a way to, in the short term, relieve or suppress negative feelings, such as sadness, stress, anger/frustration, or boredom. However, emotional eating can also lead people to make poor choices, such as skipping or forgetting meals, consuming fast food frequently, or consuming alcohol or caffeine in excess, all of which may have health consequences, including unintentional weight gain.

To help prevent emotional eating, focus on the following steps.

Identify the difference between emotional hunger and physiological hunger.

Emotional hunger typically comes on suddenly with an urge to resolve the “hunger” quickly, often involves a desire for a specific type of food or food group, and usually results in overeating. In contrast, physiological hunger tends to be more gradual, allows us to stop eating when we are full, and doesn’t typically cause guilt that is experienced with emotional hunger.

Establish a healthy eating routine.

Aim to eat two to three well-rounded meals each day. Meals don’t have to be complicated: the easier and quicker, the better. Try pairing a protein source (chicken, salmon, ground turkey or lean beef, and so on) with various grilled, roasted, or steamed vegetables and seasonings and sauces of your choice for a quick, inexpensive, and easy meal.

Ensure you’re consuming enough of the right foods. Consume plenty of fruits, vegetables, whole grains, lean proteins and low-fat dairy products while limiting your intake of highly processed foods, added sugars, salt/sodium, and alcohol. Talk with a registered dietitian to develop a healthy eating routine that meets your individualized needs while helping manage causes and symptoms of emotional eating.

Manage your overall stress.

There is evidence to suggest that increased cortisol, the hormone released during stress, may result in an increased appetite, leading to overeating and potential weight gain. Rather than turning to food for comfort, be sure to control stress by journaling, exercise, practicing mindfulness/meditation, and/or social support.

The New England Journal of Medicine published a study of adults showing that the average holiday weight gain was .37 kilograms, or just under a pound, and more than half the people in the study stayed within a kilogram, or just over two pounds, of their other weigh-ins. Now that the holidays are over, you can lose that weight and stay healthy during the long colder months. Here are five healthy habits to get started with.

1. Do make a plan to manage your stress level.

A good place to start is finding ways to ease stress and anxiety when they occur, or even before. That may mean doing yoga or meditation, taking a hot bath or shower, listening to music, or even just calling a friend to catch up.  Just 10 minutes of stress relief can help you feel more relaxed and make it less likely that you will turn to food. If you’re having trouble finding time to unwind, mark a daily 10-minute stress break on your calendar and tag it with an alert—then treat it like you would an important appointment and don’t miss it.

2. Don’t skip meals to “save up” for a big dinner.

Some people skip meals to “save up” calories for a big dinner or party, but this approach may backfire and lead to overeating later. Instead, limit your intake to an eight-hour window of time each day. This has been shown to be an effective weight-maintenance strategy. You can even try having a lighter breakfast and lunch at your usual times, making sure they incorporate a lot of vegetables and proteins with minimal carbs. For example, you might have a cup of Greek yogurt for breakfast, a green salad with grilled chicken and light dressing for lunch, and then let yourself enjoy the evening feast.

3. Do eat your foods in a specific order.

It helps to have a plate of salad or vegetables before anything else. These low-calorie and high-fiber foods will help you fill up before you dive into the higher-calorie options. Next, have some type of lean protein. If you are going to have carbs (such as potatoes, chips, rice, pasta, bread, or a sweet dessert), save them for the end of your meal. By then, you’ll be less hungry and the protein you’ve eaten will slow your digestion a bit, so you’ll feel full for longer afterward.

4. Don’t forget that beverages count.

An easy way to cut calories is to avoid drinks like regular soda, juice, coffee drinks with added sugar, and alcoholic beverages. Also, try to aim for six to eight glasses of water per day. If you do decide to drink alcohol, choose spirits mixed with something without added sugar, such as seltzer or diet tonic water, rather than beer, wine, or mixed drinks. Or stick to a drink that has only about 100 calories per serving. Do keep in mind that alcohol can lower inhibitions and make you more likely to indulge, so limit yourself to one or two drinks, and have a glass of water after each one.

5. Do give in to your cravings (somewhat).

Controlling diet and weight is a balancing act. Completely cutting out dessert and sweets is simply unrealistic. This can lead to binging or eating more than you’d like to. If you are really craving your favorite sweet, let yourself have some. Remind yourself that this won’t be your last dessert ever and try to put the fork down after one slice—or a few bites, if you’re satisfied by that.

Did you know studies have shown that the average adult gains 0.88 to 1.98 pounds during the holiday season, starting the last week of November and through the first or second week of January? For many, this doesn’t come as a surprise, especially as we tend to become more sedentary due to the weather changes and often experience an increase in temptation due to frequent holiday gatherings that focus on food, limited edition “holiday” menu items, and more. This holiday season, set yourself up for success by following these dieting “dos” and “donts” during the month of December.

DON’T: Expect your diet to be perfect during the holidays.
DO: Plan and prepare for temptation and offsets.

Let’s be realistic. There are very few, if any, people who have a perfect diet, let alone during the holidays. The holidays are a time of celebration, with food and alcohol often taking center stage at these events. It’s important to expect and prepare for temptation and to have a plan of action for practicing moderation throughout the month. Check out these 10 Simple Ways to Stay Healthy While Celebrating the Holidays for guidance on doing so.

DON’T: Skip meals to make room for your holiday meal (or alcohol).
DO: Eat a balanced diet, no matter the day, and practice portion control.

Many people attempt to skip meals to “save up” calories for heavier meals, desserts, and alcohol; however, this approach often leads to binge eating. Instead of cutting out certain foods or practically starving yourself to make up for a big meal, stick to your normal healthy eating habits or regimen and practice moderation and portion control when consuming foods rich in calories, saturated fat, sodium and sugar.

DON’T: Overdo it with the high-calorie, high-sugar “seasonal” beverages.
DO: Opt for a smaller size or customize your drink to make it healthier for you.

Did you know a grande (16 oz) Peppermint Mocha from Starbucks® contains 440 calories, 54 grams of sugar, and 16 grams of fat? Practice moderation by ordering a tall (8 oz) with only 240 calories, 28 grams of sugar, and 10 grams of fat. Or, try customizing your drink to make it healthier by asking that your drink be made with nonfat or plant-based milk, fewer pumps of sweetener/syrup, or without toppings (such as whipped cream or chocolate shavings), all of which can save up to hundreds of extra calories!

DON’T: Skip out on exercise because it’s cold or snowy.
DO: Opt for indoor exercise!

Don’t have a gym membership? Try a free online exercise video (there are TONS on YouTube) or head to a large indoor space that allows for 10 to 15 minutes of walking, such as a mall or large department store.

DON’T: Give up after one bad day.
DO: Wake up the next day, forgive yourself, and start over.

One bad day doesn’t undo all of the progress you’ve made and won’t prevent you from having success in the future. After a poor day (or two) of eating, don’t give up or put off your goals until the next week. Instead, wake up the next day, show yourself some forgiveness, and make a plan for getting back on track.

As the weather turns colder and we spend more time indoors, viruses will become more active among the population. Healthy eating can help you boost your immunity. Here are five of the top choices for fighting colds and flu with food.

Citrus Fruits

Oranges, clementines, lemons, and grapefruits are all excellent sources of vitamin C, an antioxidant that helps protect immune cells from oxidative stress during the early stages of an immune response. Research has shown that a deficiency of vitamin C can result in impaired immunity and a greater susceptibility to infection.

Fatty Fish

Fatty fish, such as sockeye salmon and rainbow trout, are often great sources of Vitamin D, a nutrient that plays a role in innate and adaptive immune responses. One study found that vitamin D supplementation resulted in a 42% decrease in the incidence of influenza infection, while another study revealed individuals with lower serum vitamin D levels were more likely to self-report recent upper respiratory tract infections when compared to individuals with sufficient vitamin D levels.

Nuts, Seeds, and Plant-based Oils

Nuts, seeds, and plant-based oils are high in vitamin E, an antioxidant that has been shown to enhance immune response and confer protection against several infectious diseases. These foods are also high in omega-3 fatty acids, which may help strengthen your immune cells, although more research is still needed to fully support these claims.

Sweet Potatoes

Sweet potatoes and other red or orange fruits and vegetables are typically high in vitamin A, which plays a crucial role in the maintenance of the human immune system. Vitamin A supplementation has been shown to have a therapeutic effect on diseases transmitted through the respiratory tract, such as pneumonia. For reference, one sweet potato contains 156% of your daily vitamin A requirements.

Oysters

Three ounces of raw oysters provides 291% of your daily zinc needs. Zinc helps the immune system function properly and also has wound-healing properties. Studies have shown that a zinc deficiency is associated with severe immune dysfunction.

***

Eating the preceding types of foods can help you strengthen your immune system against the annual winter onslaught of colds and flu. If you’d like more help planning a healthy diet, schedule a NIFS nutrition coaching session.
