If you want to lose weight
, know that you’re embarking on a long-term journey with significant health benefits. Instead of going on a drastic fad diet, focus on making small changes to your diet and lifestyle to meet modest weight loss goals at first. Focus on eating whole, healthy foods and getting physically active. Keep track of your progress and update your goals as you start to see some results and within a few months you’ll be well on your way to a healthier, happier you!
This article is based on an interview with our board certified family medicine specialist, Pouya Shafipour. Check out the full interview here.
Steps
-
Use a BMI scale to determine a healthy target weight for your height. Look online for a Body Mass Index (BMI) chart. Find your current height and age in the list or enter them into a form. You’ll see 3 weight ranges labeled “normal” or “healthy,” “overweight,” and “obese.” If your current weight falls within either of the latter 2 categories, look towards the higher end of the “normal” weight category to determine what weight you’d like to reach. [1] X Research source
- If you’re already within the “normal” weight category, weight loss may not be healthy for you. Speak with a doctor before making any changes to your diet or lifestyle. [2]

Board Certified Family Medicine Specialist Expert Interview. 8 May 2020. - Keep in mind that your natural body type will determine how your weight is distributed. Don’t expect to look like another person with the same height and weight; each body is different.
- If you’re already within the “normal” weight category, weight loss may not be healthy for you. Speak with a doctor before making any changes to your diet or lifestyle. [2]

Set small, manageable goals at the start of your weight loss program. Instead of starting off with a highly ambitious or near-impossible weight loss goal like dropping 100 lb (45 kg) by the end of the season, begin with a small goal that you can realistically achieve. In general, most teens can aim to lose 1 to 2 lb (0.45 to 0.91 kg) per week, which will quickly add up over the weeks and months. [3] X Trustworthy Source Mayo Clinic Educational website from one of the world's leading hospitals Go to source
- When you see smaller amounts of weight drop off, you’ll start to feel more motivated to set and achieve new goals as time goes on.
- Don't be disheartened if you don't lose any weight in the first week. Stay positive and stick to your plan and you’ll gradually start to see results.

Keep a food and fitness diary to track your progress. By writing down each item you consume on a daily basis, you’ll instantly become more aware of how quickly the calories can add up. Write a log of everything you eat, every exercise you do, and any weights or body measurements you take. Add up your total calorie intake at the end of each day and note how many calories you burned through exercise. Make note of any diet or lifestyle changes and refer back to the log to observe your progress. [4] X Trustworthy Source Harvard Medical School Harvard Medical School's Educational Site for the Public Go to source
- Try using a website or weight loss app to help record your diet and exercise. Many of these tools automatically estimate the amount of calories consumed or worked off for each line item.
- Analyze the contents of your food diary to see what’s working and what isn’t so you can adapt accordingly. For instance, if you notice that you always have a vending machine snack after swim practice, you can start bringing a piece of fruit along so you have something healthier to eat.
-
Weigh yourself once per week in the morning. Step onto the scale on the same day each week, at the same time. To get the most consistent reading, weigh yourself in the morning before you eat breakfast and after you go to the bathroom. [5] X Trustworthy Source Cleveland Clinic Educational website from one of the world's leading hospitals Go to source Measure around your waist, hips, thighs, and upper arms, too, so you can see where you’ve lost fat. [6] X Research source
- Weighing yourself every single day can lead to weighing scale obsession, or an unhealthy fixation on daily results. Water retention in the body can add as much as five pounds per day, so the scale can also be somewhat misleading.
- Remember that weight loss is an ongoing process. Developing healthy habits and losing weight takes months and years; it won’t happen in a matter of days.
-
Be kind to yourself along your weight loss journey. Emotions and stress can make weight loss feel like an uphill battle. But with a realistic set of small, manageable goals and a system for tracking your ongoing progress, focus on keeping a positive outlook. Celebrate each minor and major success and forgive yourself if you fall short of your goals or slip up from time to time. [7] X Research source
- If you spend a day vegging in front of the TV instead of hitting the gym, don't beat yourself down. If you indulge in a bunch of junk food after a stressful exam, don't worry too much. Just commit to getting back on track tomorrow!
- Clinical nutritionist Tara Coleman suggests starting slow when adding healthier eating habits to your life. “You wouldn’t go into a gym and lift the heaviest thing right away; you’d start with smaller weights and work your way up. The same thing goes for food: start with one small change and then build on that rather than trying to overhaul everything at once.” [8]

Give your body the right number of calories every day. The amount of calories you’ll need to consume on a daily basis depends on your age, sex, height, and on how active your lifestyle is. Teen boys need around 2,800 calories per day while teen girls require 2,200 calories per day. [9] X Trustworthy Source HealthyChildren.org Health information from the American Academy of Pediatrics. Go to source Look online for charts listing caloric intake recommendations or speak with a doctor to determine a target number. Then, as you plan your meals and track your daily intake with your food diary, aim to eat no more than your target number of calories.
- A 14-year-old boy who’s heavily involved in sports might need up to 3,000 calories, whereas his classmate who doesn’t lead a very active lifestyle might need only 2,000. However, a 14-year-old girl with a moderately active lifestyle would need about 2,000 calories per day as well. [10] X Trustworthy Source National Health Service (UK) Public healthcare system of the UK Go to source
- If you do eat too many calories on Monday, don’t restrict your intake on Tuesday. This will only result in an unhealthy cycle of overeating and starving yourself.
-
Cut sugary drinks out of your diet. Avoid drinking soda, sports and energy drinks, fruit juice, and sugary frozen drinks. Instead, stick with water or sugar-free beverages. Instead of drinking fruit juice from concentrate, try making your own fresh fruit juice at home with a juicer. Drink low-fat milk, too, to get some calcium into your diet.

Reduce your portion sizes at each meal. Ask for smaller portions at meal times or dish yourself about 30 to 50% less than you’d normally take. Limit the amount of food on your plate so you’re not tempted to clear your plate. [15] X Research source Try eating on a smaller plate, too.

Fill your diet with whole foods, fresh fruits and veggies, and lean protein. Steer clear of processed snacks, sweet baked goods, and greasy junk foods. Aim to eat 5 servings of fruit and vegetables each day, and try to have them make up half of each meal. Opt for whole-grain bread, rice, and pasta as well as lean proteins like poultry and fish. End your meals with naturally sweet fruits instead of sugary desserts.

- Pick baked, grilled, or steamed proteins over fried or breaded foods.
- Look for “light” or “low-calorie” options on restaurant menus when you go out to eat. This will ensure that you still have a great time and a delicious meal while sticking to your weight loss plan.
- It’s okay to enjoy sweet treats in moderation. You don’t need to cut your favorite pizza joint out of your life or refuse your friend’s birthday cake. Have a slice every once in a while, but stick to just the 1 slice. Skip the soda and swap potato chips for carrots to make your overall meal healthier. [21]

Avoid eating when you’re full or feeling down. During a meal, pay attention to how your stomach feels.
