November 8. 2022

Nowadays, you don’t have to rely solely on diets and exercise when trying to lose weight. While both these elements are absolutely necessary to lose the excess pounds, you can also count on medical weight loss supplements; these can do wonders for your body by helping you lose weight quickly or break the weight loss plateau. With a good diet plan and regular exercise, weight loss supplements really make a difference in your weight loss journey.  One of the most common weight loss supplements includes weight loss pills such as phentermine. Our experts from our weight loss clinic in Chicago recommend using phentermine for people with a high Body Mass Index (BMI) or weight-related health problems. As mentioned before, this kind of supplement aids you in losing weight fast. Of course, phentermine cannot make its magic without a healthy lifestyle and changes in your diet. Supplements are here to help you reach your goal, but they can not do it on their own. Losing weight requires your commitment to start eating healthier and avoid the intake of foods that increase your weight and prejudice the effects of weight loss supplements. You should check with a professional about the right meal plan for you and do your best to stick to it. You can start with small changes, like cutting off some foods and taking a 20-minute walk every day. By doing so, you’ll start seeing results fast and take full advantage of weight loss supplements such as phentermine.

What is phentermine?

Phentermine for weight loss is one of the most successful drugs on the market. Phentermine is a stimulant; it works by suppressing your appetite. That way, you’ll have fewer cravings, eat less, and it will be much easier for you to follow a low-calorie diet. This drug also boosts your metabolism, which helps you lose weight fast.

Phentermine weight loss pills are meant for patients with a BMI higher than 30 or those who suffer from weight-related diseases such as diabetes, high blood pressure, or high blood sugar levels. If your BMI is normal, you probably don’t require phentermine; you will likely reach your weight goal by maintaining a healthy diet plan and working out regularly. If losing weight is still hard for you, maybe you aren’t following the best meal plan for your particular situation. You can contact a professional dietitian to guide you and share some useful weight loss tips.

Phentermine should always be prescripted by a certified health professional. We discourage you from taking any unprescribed medication which can harm your health. During a medical checkup, your doctor will communicate the proper use of phentermine; you’ll probably have to stick to a particular dose for a given time – typically a couple of +

months. Following a strict diet plan while taking phentermine is crucial to obtain all the benefits of the drug. You should keep in mind that phentermine will help you lose weight, but healthy eating habits are still necessary. A phentermine diet plan is what will take you to your dream weight.

The importance of having a proper diet plan while taking phentermine

Phentermine pills and a suitable phentermine diet plan can help you kick-start a fast and smooth weight loss journey. It is essential to follow a diet plan and eat only the right food to lose weight. If you want to lose weight fast, phentermine will take you there, but a meal plan can not be evaded.

Phentermine works by suppressing your appetite; while taking the drug, you’ll be full longer and won’t have so many cravings throughout the day. It’ll be easy for you to maintain high energy levels while consuming fewer calories. A good diet plan full of proteins and fiber is necessary to ensure you’re incorporating all the nutrients you need. A proper phentermine diet plan will include foods rich in fiber, proteins, and healthy fats while excluding extra processed foods and foods high in sugar and calories.

By adhering to a healthy diet plan during the time you take phentermine, you’ll create healthy habits that will stick around once you’re off the drug. Once you accomplish your mission and lose all those extra pounds, you’ll have to keep working on maintaining the desired weight. Leading a healthy lifestyle is the best way to do so. We leave you a comprehensive guide if you’re unsure what you can and can not eat while taking phentermine. Follow these valuable tips to take full advantage of the phentermine benefits.

Foods to consume while taking phentermine

Before telling you what to eat, we’ll tell you something equally important: what to drink. Water has an immense impact on the phentermine efficacy; you should drink at least 8 to 10 glasses of water per day while taking this drug. Moreover, drinking enough water should be a part of any diet plan you’re following, especially if you want to lose weight. By staying hydrated, you won’t risk mistaking being dehydrated for hunger. Also, drinking enough water throughout the day can help you speed up your metabolism and lose weight. With all this in mind, water is the first thing you should write down for the phentermine diet plan.

The next on the list are foods rich in protein and fiber. Keeping in mind that you should stay below the 1500 calories a day, a good phentermine diet plan includes:

Vegetables and Fruits

Vegetables and fruits contain a high amount of fiber and water. Most vegetables are low in calories and contain a lot of nutrients. Fruits have sugar, but unlike candies or treats, these are healthy sugars. Try picking whole fruits instead of juice ones, as they have more fiber. Some fruits and vegetables can even help you lose weight – like an avocado smoothie for weight loss.


Most fish and seafood contain a lot of protein and healthy nutrients. Plus, fish proves omega-3 acids, which most people fail to include in their diet. We recommend you consume fatty fish such as tuna, salmon, herring, mackerel, and anchovies.

Nuts and seeds

Your diet should include almonds, walnuts, chia seeds, and hazelnuts. Just remember, nuts are high in calories and fats, so only include a couple per day. Nuts can come in handy if you still feel hungry in between meals. Just eat a couple of your favorite nuts as a snack.

Whole grains

Whole grains bring a lot of great benefits for your health, like reducing your chances of suffering heart disease. It’s refined grains that you should avoid, foods such as white bread. Whole grains are rich in fiber and help you stay satisfied longer.

Legumes and Beans

Beans and legumes are high in proteins which help you burn calories and fat stores. Consuming them will make you feel full longer. They’ll also aid you in lowering your sugar levels and blood pressure. You have a wide variety to choose from black beans, kidney beans, chickpeas, or navy beans.

Foods to avoid in your phentermine diet plan

Understanding the foods to avoid is as important as knowing what you should consume. At the beginning of the allowed foods section, we mentioned the importance of drinking enough water. In that instance, alcohol and sugar drinks are off the table. Alcohol and phentermine combination is a big no. Consuming alcohol while taking drugs is never a good idea; in this case, alcohol can even counteract the effects of phentermine. Sweetened drinks such as soda or energy drinks contain a lot of empty calories that bring no nutrient values and can lead to weight gain.

Essentially, you’ll have to avoid sugar, alcohol, junk food, fried food, refined carbs (white bread, pasta, flour), and processed meats (sausages, bacon). If you still feel some cravings throughout the day, you can opt for a healthy snack like a piece of fruit or a protein bar. Protein bars are a great source of macronutrients and give you plenty of energy, but keep in mind they don’t replace meals. How many protein bars a day you can eat depends on your specific diet plan and the type of protein bar you choose.

Tips for improving the phentermine efficiency

If you want to boost the effect of phentermine, you can try some lifestyle changes. Leading a healthy lifestyle is of great help when trying to lose weight. Low levels of stress are recommended during your weight loss journey. Another important aspect is getting enough sleep. A proper sleep schedule will lower your stress levels and give you enough energy to take over your day. Insomnia is one of the possible side effects of phentermine; you should be aware of it.

Staying hydrated and sticking to a healthy diet plan will also help improve phentermine efficiency. Remember to drink enough water throughout your day, since your brain easily mistakes thirst for hunger. If you’re following a diet plan, and you still feel hungry from time to time between meals, try drinking a glass of water first. If you don’t drink enough water, your body will retain water instead of releasing it. That water weight will show up on the scale. Eating enough nutrients is equally important; while following a low-calorie diet, you should never consume less than 1200 calories a day.

Exercise is excellent for your body and mind. Besides boosting the efficiency of phentermine, working out will improve your mood, help you sleep better, and keep you full of energy. The benefits of including a workout routine in your life are countless, and any type of exercise will aid you in losing weight. Remember that you can always start with baby steps. Go for a walk every day, sign up for a dance class, or a sport you love. By starting small, you’ll make sure not to feel overwhelmed by so many changes, and you won’t quit so easily. All physical activities are welcomed when trying to lose weight. However, cardio and weights paired with phentermine work perfectly to lose weight. Weight and cardio complement each other well; those workouts will help you burn calories fast and build lean muscle mass. That will improve your metabolism and help you stay in shape.

Start today to incorporate small changes into your routine. Every step you take towards a healthy lifestyle, no matter how small, will boost your weight loss. By doing so, you’ll take full advantage of all the benefits phentermine provides.
