Weight Loss Injections Q & A

How Do Weight Loss Injections Work?

Weight loss injections such as lipotropic fat-burning injections, or B12 shots, work by boosting your metabolism, allowing your body to quickly process the foods that you ingest and get the most out of the nutrients in your diet.

B12 injections may also give you a boost in energy, allowing you to feel motivated to exercise. While these results aren’t proven, many attest to their effectiveness alongside a weight loss plan that includes a healthy diet and adequate exercise.

Your provider works with you to determine how frequently you should get your B12 injections, depending on your weight, height, and other factors. Generally speaking, B12 injections work best when administered once a week. This is because they boost the levels of your amino acids, which return to normal after roughly seven days.

When Might I Need a B12 Injection?

B12 injections aren’t necessary for everyone, especially since most people get plenty of vitamin B12 in their diet through animal-based foods or supplements. A B12 injection might be recommended for you if:

  • You drink alcohol regularly
  • You’re a vegetarian or vegan
  • You have an immune system disorder
  • You’ve had gastric bypass surgery or a similar operation
  • You have a condition that makes it difficult for your body to absorb vitamin B12


Your body also has greater difficulty in absorbing nutrients and vitamins as you age, so older people may also be good candidates for B12 injections. Your provider can help you determine if a B12 injection would benefit you.

What are the Risks of Weight Loss Injections?

Side effects of weight loss injections such as lipotropic fat burning injections are rare but do exist. They include:

  • Gastrointestinal issues
  • Urinary issues
  • Fatigue
  • Unexplained pain


Like any injection, there is a slight risk of an allergic reaction in addition to these rare side effects. If you notice a rash or irritation after an injection, contact your provider immediately.
