Healthy weight loss plans include eating well, being physically active, and getting enough sleep so you feel your best now and for the long term. Health is about more than a number on the scale, so this weight loss advice looks at the bigger picture.

There are no quick fixes or fad diets that are known to sustain weight loss in the long term. These weight loss plans and fad diets are based on restricting calories or removing specific food groups. Most of the time, it's impossible to follow these plans in the long term, so weight loss is not maintained over time. That's why this article offers sensible nutrition, exercise, and sleep goals, that can be sustained for life. A healthy lifestyle can help you feel your best now while preventing chronic diseases in the future.

Instead of going "on a diet" which you eventually go "off," this sustainable plan includes realistic goals and small changes that can last a lifetime. It also includes a variety of delicious and nutritious foods, as well as exercise that's fun and enjoyable, and tips on healthy sleep.

Setting Realistic Goals

First, decide if weight loss is the right strategy for your health. It's common to have an unrealistic view of what a healthy weight really is. Use this guide to determine what your ideal weight is so you can set an appropriate goal.

If you need to lose weight, aim to lose 1 to 2 pounds per week (or 4 to 8 pounds in 30 days). People who lose weight slowly and gradually are more likely to keep the weight off long term compared to those who lose a lot of weight very quickly.

Set SMART goals that are:

  • Specific
  • Measurable
  • Attainable
  • Relevant
  • Time-bound

A goal such as "I will lose 10 pounds" is not time-bound (no timeline is set) and may not be attainable, since weight fluctuates based on many factors, such as hydration, hormones, medications, food intake, and activity level.

A SMART goal that contributes to weight loss may be: "I will replace my daily can of sugar-containing soda with water for the next 30 days." It's more important to set goals about sustaining a healthy lifestyle than about reaching a target number on a scale. The goal of reducing sugary drinks is more realistic than "I will lose 10 pounds," which is harder to control or achieve.

Creating a Nutrition Plan

Eating well plays an important role in weight loss and maintenance. A winning strategy for weight loss includes both caloric restriction and adequate exercise. While calories are part of weight control, it's too narrow to think that energy-in and energy-out is the only factor to consider in weight loss. These factors are also involved:

  • Hormones
  • Medical conditions
  • Physical activity levels
  • Medications
  • Sleep
  • Genetics
  • Environment
  • Mental health
  • Economics

Your best bet is to work with a health care professional for a personalized weight loss plan. If that is not possible, you can follow the general information in the Dietary Guidelines for Americans about the role of nutrition in weight loss. It recommends a varied diet that includes:

  • Vegetables and fruit
  • Grains (including whole grains)
  • Protein foods
  • Dairy
  • Oils

The amount (portion) of food that you should eat is specific to your current weight and your weight loss goals. Learn more about how to set calorie goals here. Even if you cut back on calories, it is important to eat a variety of foods to get all of the protein, healthy fats, vitamins, and minerals that your body requires. It's also vital to focus on aspects beyond food. Physical activity, hydration, sleep, and other components are all interconnected in your weight loss journey.

Meal Planning

Your body requires nutrients every day so it functions properly. The Dietary Guidelines were designed to ensure that nutrient needs are met with a variety of foods including vegetables, fruit, protein, and grains. You can plan meals using the five food groups in the USDA's My Plate model. When you plan meals, consider these plate proportions:

  • Make half your plate vegetables and fruits.
  • Make a quarter of your plate grains. Choose whole grains at least half of the time.
  • Make a quarter of your plate protein from foods such as poultry, fish, eggs, meat, legumes, nuts and seeds.
  • Have a serving of calcium-rich foods such as milk, soy beverage, or yogurt.

The exact amount of food you will need depends on your goals (see section above). In addition to eating more whole foods like vegetables, you can also cut back on heavily processed foods like fast food, packaged snacks, baked goods, and candy.

A simple meal plan may look like this. You can repeat this 5-day plan 6 times to complete a 30-day plan.

Day 1

  • Breakfast: Plain Greek yogurt with strawberries and low-sugar (3 grams of sugar or less per serving), oat-based granola
  • Snack: Almonds and grapes
  • Lunch: Tuna melt sandwich with cheese and tomatoes on whole grain bread, served with carrots, red peppers, and an apple on the side
  • Snack: Cucumber and hummus
  • Dinner: Chicken with brown rice and stir-fried vegetables.

  • Snack: Cheddar cheese and an apple
  • Lunch: Poke bowl: fish (or tofu) with brown rice, mixed vegetables, seaweed and sesame seeds

Day 3

  • Dinner: Lemon-butter halibut with green beans and potatoes

Physical Activity

Being physically active is associated with weight loss because exercise it burns calories. The CDC suggests 150 minutes per week of physical activity for health benefits. However, this amount may not be enough for weight loss. International guidelines recommend 300 minutes of exercise per week for people trying to lose weight.

Nutrition and exercise are both important factors in weight loss. Studies show that exercise only—without dietary changes — may help with a small amount of weight loss, but is not likely to result in meaningful weight loss. Diet and exercise are both important and should be paired together for the best results.

It's important to choose physical activities that you enjoy so you are more likely to stick to them for the long term. Choose a combination of both aerobic (biking, walking, dancing) and strength-building activities (weight lifting, resistance bands, push-ups) for the best benefits.

As a beginner, start by taking a walk every day and lifting light weights. Walk for longer and do more reps with your weights as the weeks go by. Consider these exercise tips for beginners.

Hydration and Sleep

Other factors that affect weight include hydration and sleep. When it comes to fluid and hydration, many Americans rely on sugar-sweetened beverages. However, excess intake of sweet beverages is linked to weight gain.

Water is a better choice than sweet beverages when trying to manage weight since it contains no calories or sugar. Replacing sugary or calorie-rich beverages with water can help with weight loss. Some studies indicate that drinking water before meals may decrease food intake during meals, which may help eaters feel more satisfied with fewer calories. Staying hydrated is important because studies show that consistently being under-hydrated is associated with increased body weight.

Studies also show a connection between sleep patterns and weight. Poor sleep is linked to increased calorie intake, mostly from snacks that are high in fat and refined carbohydrates. Poor sleep also may affect hormones involved in weight, appetite regulation, and metabolism.

Some evidence suggests that people who sleep less than seven hours per night are more likely to have obesity. If you don't sleep for at least seven hours per night, consider working with a sleep specialist as part of your weight loss program. Here are some tips to help with better sleep.

Tracking Progress

If you set measurable goals, it's easier to track your progress. For example, if your goal was to drink water instead of soda at lunch for 30 days, you can mark each day on a calendar to check your progress.

Some people like to keep a food or exercise journal to monitor progress or use a mobile app to count calories or steps. Make sure to celebrate your successes. If you falter, start again as soon as possible.

One caution for tracking progress: try not to gauge your progress based on a number on the scale. Making lifestyle changes such as improving your eating habits or being more active has so many benefits beyond weight control.

Coping with Challenges

The Dietary Guidelines for Americans recognize that losing weight is not easy and is best achieved with a commitment to lifestyle change over the long term and with the help of medical professionals.  

You will have a better chance of sustaining long-term weight loss if you make slow, steady progress that includes a combination of nutrition, fitness, sleep, and hydration changes.

In order to see real progress, don't make too many changes at once. Build up slowly instead. Perhaps the first 30 days of the journey may have progress such as:

  • In the first week, you drink water instead of a soda at lunch.
  • In the second week, you have water instead of soda and walk 10 minutes per day.
  • In the third week, you continue the first two activities and add weight training twice a week.

Remember, 30 days is just the start of this journey. Maintaining these new habits lifelong is how you will see real progress.
