"I want to lose 5kg in a month." "I followed a popular diet exactly, but I gained it back quickly." "Are injections better, or oral medications?"

When consulting for diet in Pyeongtaek, many people come with a target number on the scale already set. However, the background of weight gain differs for each person. For some, irregular meals and late-night snacks are the cause, while for others, lack of sleep, alcohol consumption, decreased activity, or medications being taken are linked to weight gain. There are also cases where underlying health issues, such as Polycystic Ovary Syndrome or thyroid disease, need to be checked first. Therefore, rather than simply eating less, diagnosing the cause of current weight gain and any co-existing conditions is the starting point for dieting.

Obesity is not just an issue of appearance. Excessive accumulation of body fat can affect blood pressure, blood sugar, and cholesterol levels, and can also be linked to fatty liver, sleep apnea, and joint strain.

During consultation, we check your Body Mass Index using your height and weight, and also look at your waist circumference and body composition. This is because even with the same Body Mass Index, different muscle mass and abdominal fat levels can result in different health risks. Whether your weight has suddenly increased recently and what methods you have tried for weight loss in the past are also important information. Blood pressure, blood sugar, liver function, and lipid levels are selectively checked depending on your individual condition.

The method to be used, including medication, is determined after checking the following items during the diagnostic stage.

If you drastically reduce your daily intake all at once, your initial weight may drop quickly. However, extreme restriction can lead to fatigue and decreased concentration, and as muscle mass is also lost, there is a higher chance of weight rebound after stopping.

Rather than completely cutting out carbohydrates or eating only one type of food, it is more realistic to find areas to adjust in your usual diet. You can start by looking at calories that come in unnoticed, such as from beverages, snacks, late-night meals, and frequent dining out. It is necessary to incorporate appropriate amounts of protein and vegetables into your meals and to develop the habit of eating a set amount slowly. It can also be helpful to record whether you eat due to stress or habit when you are not actually hungry. If you are looking for diet treatment in Pyeongtaek, check if they provide a plan tailored to your occupation, daily schedule, and frequency of dining out, rather than just giving you a standardized meal plan.

While it is difficult to lose a lot of weight in a short period with exercise alone, controlling your diet alone is also not sufficient. Exercise is meaningful in maintaining muscle mass during the weight loss process and managing cardiovascular function and metabolic health.

Starting with high-intensity exercise every day can easily strain your knees and back or lead to quick exhaustion. You can consider starting with aerobic exercises like walking and cycling, tailored to your current physical condition, and gradually adding strength training about twice a week. If it's difficult to set aside time, simply walking short distances and breaking up long periods of sitting can be helpful. The fundamental principle of obesity treatment, which is lifestyle modification including diet and physical activity, remains unchanged.

If weight loss is difficult despite lifestyle changes, or if there are weight-related health issues, obesity medications may be considered based on the medical professional's judgment. Each medication works differently, affecting appetite, satiety, or fat absorption, and it is not possible to uniformly say whether injections or oral medications are better. The choice is made after checking Body Mass Index, co-existing conditions, current medications, pregnancy plans, and medical history.

When using obesity medications, drug-specific adverse reactions such as nausea, constipation, diarrhea, dry mouth, and palpitations may occur. If you experience discomfort, you should consult the prescribing medical professional rather than self-adjusting the dosage or adding medications obtained from the internet. When choosing a Pyeongtaek diet clinic, it is better to consider whether they sufficiently explain the indications, expected adverse reactions, and post-discontinuation management, rather than whether they easily prescribe specific medications.

Dieting is not a treatment that ends the day you reach your target weight. If you immediately return to your old lifestyle after weight loss, your weight may increase again, so a maintenance phase is needed to continuously manage appetite, activity level, and sleep duration.

If you set your goals too high from the start, small changes may not be noticeable. You should look at changes in health indicators such as waist circumference, blood pressure, blood sugar, physical fitness, and sleep status, in addition to weight. There will also be periods when your weight temporarily plateaus. At this time, rather than further reducing food intake or increasing medication dosage, the correct sequence is to re-examine your food records, activity level, sleep, constipation, and alcohol consumption.

Which is better, injections or oral medications? There is no universally fixed answer. The appropriate option is chosen after checking Body Mass Index, co-existing conditions, current medications, pregnancy plans, and medical history. Won't drastically reducing meals lead to faster weight loss? It may lead to initial weight loss, but muscle mass also decreases, making it easy to regain weight after stopping. Sustainable adjustment is the priority. What should I do if I feel uncomfortable after taking medication? Do not adjust the dosage yourself; consult the prescribing medical professional. My weight has plateaued, should I increase my medication? Before that, re-examine your food records, activity level, sleep, constipation, and alcohol consumption.

When choosing diet treatment in Pyeongtaek, we recommend looking for a place that confirms the cause of weight gain and any co-existing conditions, rather than one that only emphasizes short-term weight loss figures. The sequence is to base treatment on diet, exercise, and sleep, and only add medication when necessary. A diet plan or prescription that worked for someone else may not work for you, and there are individual differences in the speed of weight loss, treatment response, and adverse reactions. If you want an accurate diagnosis of your current condition and a personalized plan, feel free to inquire via Chat Consultation.
