Weight Loss Pills vs. Weight Loss Injections - What is Best for Me?

Weight loss pills are another option to start your weight loss journey. But are they the best option available? Let's find out.

The most popular and widely used pill available in the UK is Orlistat. You can find it under brand names like Alli or Xenical

Weight loss pills limit the fat absorption in your body. Your body will significantly reduce the absorption of fat from your meals. Hence, restricting fat absorption reduces your overall daily calorie intake. Weight loss pills are taken between or one hour after every major meal.

Weight loss pills are prescribed to people with a BMI over 30 or greater than 28 if they face obesity-related risks.

Weight loss injections and weight loss pills work differently and have different side effects. [4] Selecting the best is difficult because it's not one size fits all. Everyone experiences different obesity-related problems and has a different lifestyle.

It's better to let a medical professional decide for you. Make sure you have mentioned all your symptoms and weight-related conditions.

Do Weight Loss Injections Really Work?

Yes, weight loss injections are an effective way to achieve your weight loss goals. However, weight loss injections require a consistent and healthy diet plan to show the best results. Also, integrate at least one hour of physical activity into your daily routine to make the most out of weight loss injections.

Saxenda has proven effectiveness of up to 10%, and Wegovy tops the competition with 15%. Also, weight loss injections show results once your body gets used to the medication. Although the time period may differ for everyone, the general time is 8 weeks. However, it's important to note that these results are not obtained solely by weight loss injections but combined with significant lifestyle changes.

How to Choose the Right Weight Loss Injection for You?

Choosing the best weight loss injection might be a confusing task for many people. We understand your struggle. Consider these factors before selecting the right weight loss injection for you.

What Suits You?

You must contact a healthcare professional and have a detailed discussion, mentioning all your problems and concerns. You should also mention all the medical conditions you have.


The cost of weight loss injections is another factor to consider. Compare the weight loss injections' prices and dosage frequency to find the best option.


Another important factor to consider is accessibility. Look out for the options that are available in your vicinity.

Which Weight Loss Injection is the Best?

Wegovy and Saxenda are both FDA and MHRA-approved weight loss injections. The major difference between both medications is the active ingredient and the dosage frequency. The Wegovy has the active ingredient Semaglutide, whereas the Saxenda uses Liraglutide as the active ingredient. It's important to note that both ingredients belong to the same drug family, GLP-1 receptor agonists.

Another major difference is that the Wegovy has a dosage frequency of once a week, and if you choose Saxenda, you will have to inject it daily, which often leads to injection marks and pain at the injection site.

No two people experience the same obesity-related symptoms and have the same lifestyle. This is why it’s better to let a healthcare professional and an expert determine which weight loss injection would be best for you.

Causes of Weight Gain and How To Put An End To It?

When our daily calorie intake exceeds the calories burnt that day, the excess calories are converted to fat. Eventually, increasing your weight and BMI.

Unhealthy Diet

The most common reason for weight gain is improper diet. Everyone has different nutritional demands, which vary depending on sex, age, weight, and health conditions. A diet that does not consider the requirements is categorised as unhealthy.

  • Avoiding the following would help you in achieving your weight loss goals faster:
  • Fast foods: Contain a high amount of saturated fats
  • Sugary drinks: juices, soft drinks, and milkshakes are all sugary drinks
  • Alcoholic beverages: full of calories and added sugars
  • Fried items: loaded with saturated fats and high in sodium

Medical Conditions

Some medical conditions also stimulate weight gain. The following list includes the medical conditions that are generally the cause of weight gain:

  • Depression,
  • Hypothyroidism
  • Insomnia
  • Arthritis (due to decreased activity)
  • Prader-Willi syndrome
  • Diabetes (Type 1 and 2)

If you feel your medical condition is causing you to gain weight, contact your general physician to find out a long-term treatment for the medical condition and the weight loss.

Sedentary Lifestyle

A sedentary lifestyle is where you spend more than 6 hours or more either lying down or sitting. The lifestyle includes near to no physical exercise and activities. Consequently, your body adds up the calories and stores them as fat.

Hormonal Medicines

Some medicines have weight gain as a side effect. These medicines are mostly hormonal in nature. The list includes the common medicines known to cause weight gain.

  • Birth Control
  • Oral corticosteroids
  • Antiepileptics
  • Antipsychotics
  • Antidepressants

If you suspect your medicines are causing you to gain weight, discuss your current medications with your doctor.

The Risks of Obesity

Obesity does not immediately result in health threats, but long-term risks of obesity involve

  • Cardiovascular problems - Heart failure, stroke, high blood pressure
  • Low self-esteem
  • Sleep apnoea
  • Gastro-intestinal diseases
  • Osteoarthritis
  • Irregular menstruation and infertility
  • Erectile dysfunction
  • Diabetes
  • Cholesterol fluctuations (High LDL cholesterol and low HDL cholesterol)

When Should You Consider Losing Weight?

It's essential to know whether you really fall into the category of overweight people or not. The best way to check if you are overweight is to keep an eye on your BMI (Body mass index). It uses your height and weight to determine how healthy your weight is.

The BMI separates people into the following categories according to their weight.

  • Underweight = <18.5
  • Healthy range = 18.5 to 24.9
  • Overweight = 25-29.9
  • Obese = >30

Remember that BMI is only partially reliable. It only considers the weight, regardless of the type. It does not differentiate between water, bone, or muscle weight. This is why many muscular people also get identified as overweight by their BMI.

To tackle this issue, you can consider your body fat percentage. Compared to BMI, it is a more reliable indicator of your obesity. People with a body fat percentage above 25% are considered obese.

Obesity is a major concern in the UK. According to The Health Survey for England, 25.9% of people were obese, and 37.9% were overweight in 2021.

Lifestyle Changes To Lose Weight Permanently

Lifestyle changes are important to notice results in your weight loss journey and achieve your goals.

Healthy Diet Plan

It is important to follow a healthy diet plan to lose weight consistently. You must burn fewer calories to stay in shape if you consume fewer calories. This is why most medicines aim to strengthen the feeling of satiety.

Try to draft a practical diet plan that is easier to follow in the long term instead of a short-term fad diet. Include a higher portion of protein in your diet, accompanied by fruits and vegetables. Try to avoid saturated fats and carbohydrates.

Physical Activity

If you have a sedentary lifestyle, try changing it with utter determination. In not more than 2 weeks, you will start seeing the results. You will notice better mobility and feel more energised after integrating at least one hour of physical activity thrice a week into your daily routine.

Try using a wellness and fitness tracker to maintain consistency.

Mental Wellness

Mental wellness significantly impacts your weight. Plus, while making changes in your lifestyle, you will have mood swings and experience a difference in your behaviour. Know that it's perfectly normal.

Record your thoughts and try to journal your feelings. Not only will this help you organise your thoughts, but it will also analyse your goals and track how far you've come.

You can also ask for help from a trained psychotherapist or psychologist. Everyone needs help, and it's completely okay to ask for it.


Your diet is your most important asset. It shouldn't be compromised under any circumstances. Reflect on your health and check which category you fall into. If you are overweight with obesity-related medical conditions or your BMI exceeds 30, and you fall into the category of obese, there is no need to fall into the valley of despair.

Weight loss injections are a viable option to start your weight loss journey. However, it would help if you made significant lifestyle changes quickly to get the desired results. Add at least 30 minutes of physical activity to your daily routine. Stick to a high-in-protein diet to limit your calorie intake and make your weight loss journey easier.
