How to Lose Weight

How to Lose Weight

Every time you pick up your phone or flip on the TV, you see a new diet, workout, or routine that promises to help you drop extra weight. So, how do you know where to start?

Start here! This guide gives you five behaviors that will help you lose weight with (or without) phentermine, plus maintain a healthier weight long-term.

1. Weigh Daily

If you’re chasing a weight-related goal, it’s important to measure and track how much you weigh over time.

Research shows that daily, or at least frequent, weigh-ins are an important habit for weight loss and maintenance ( 1 ). If you’re watching for a pattern it’s important to weigh yourself around the same time each day because the average adult’s weight fluctuates by up to six pounds from morning to night ( 2 ). If you can avoid obsessing over the number on the scale, daily weigh-ins help you stay aware of your weight and its natural swings.

Scales like Withings Body, Body+, and Body Cardio will also track body mass index (BMI), body fat percentage, and even heart health – all synced into an app on your phone.

All of these functionalities make a smart scale an invaluable tool for your weight loss journey, no matter whether you love checking the numbers daily or letting the app do all of the tracking for you.

2. Eat Nutritiously

Once you’ve measured your starting weight and thought about goals, diet is the next step. What you eat is the most important determinant of weight loss and weight maintenance.

Each day eat 500 calories less than normal to lose one pound per week, or 1000 calories less than normal to lose two pounds per week. At its most basic, each pound of fat is equivalent to 3500 calories of energy. That means that eating 500 calories less per day for 7 days forces your body to burn off about one pound of fat for fuel ( 3 ). The fat that’s burned for fuel comes right off your hips, stomach, thighs or wherever you hold fat.

However, it’s not just the quantity that matters. Quality matters, too. Make half your plate full of non-starchy fruits and veggies, one-quarter of lean protein, and one-quarter of whole grains. Use healthy fats to prepare and complement your food ( 4 ).

TIP: It’s deceptively easy to eat a few hundred calories but much harder to burn off those extra calories with exercise. Pay attention to portion sizes.

3. Exercise Regularly

Exercise has many health benefits, including weight loss

Exercise is great for your health, and not just because it burns additional calories. People who exercise regularly have stronger immune systems, more energy, better heart health and less anxiety ( 5 , 6 ).

Experts recommend 150 minutes per week of vigorous exercise – or 300 minutes of moderate exercise – plus two days of strength training ( 7 ). Vigorous exercise includes activities like running, swimming or spinning. Moderate-intensity activities include walking, cycling or using the elliptical trainer.

Do 30-60 minutes per day seem a bit unattainable at the moment? Don’t worry: research shows that short bursts of activity promote health and weight loss as well ( 8 ). In the end, it’s being too sedentary for too long that produces the most negative health consequences, so just standing up to walk around the office each hour is a big step in the right direction ( 9 ).

A watch that tracks and encourages your fitness goals promotes not only weight loss, but also overall health.

4. Reduce Stress

Learning to manage stress helps your body store less fat

You’re putting in the effort to eat right and stay active, so don’t forget about stress management.

Chronic stress has been shown to slow metabolism, increase cravings for salty, high-fat food and cause fat to accumulate around the stomach ( 10 , 11 ). These effects are largely attributable to the build-up of a certain hormone called cortisol, which spikes during periods of stress.

Thankfully, taking just one minute to control your breathing can significantly reduce tension and stress.

Close your eyes and breathe in through your nose for 4 seconds, hold for three seconds, and then exhale slowly for one second. Repeat four times and feel the stress slide away.

Watches that track your heart rate, such as the Steel HR, are also an immense help with this because they monitor your stress and let you know when you most need to take a moment to relax.

5. Consider a Boost

Medications and supplements can help you reach your goals faster

If you’ve tried the lifestyle changes above and still aren’t seeing the weight loss you’re looking for, consider another medication or a supplement to boost weight loss.

Phentermine is one option. It is a prescription-only appetite suppressant that can only be taken for a short period of time, but these pills have helped millions of patients around the world reach their weight loss goals.

While taking phentermine, always take your medication exactly as prescribed and follow doctors’ orders about diet and exercise.

If you aren’t interested in prescription-strength diet pills, consider PhenQ. This all-natural dietary supplement suppresses appetite and boosts energy to help you reach your weight loss goals faster.
