Do B12 Shots Help You Lose More Weight?

You may have heard of some programs that offer B12 injections as part of their package to help speed up weight loss.

Other than getting stabbed with a needle, this seems like a pretty sweet deal.  Stick to my plan, get a shot of B12 and continue losing weight.  But do these shots really work?  Let’s further investigate….

People who regularly take B12 injections say that the shots give you more energy and boost your metabolism, which therefore helps you lose weight.  Others have said that it makes them feel great and healthy.  Then there are the people on the other end of the spectrum who say that they don’t notice a difference.

The truth is that unless you have a vitamin B12 deficiency, the chances of the injections giving you an energy boost are slim to none.   In most cases, this is just a gimmick to get you hooked on specific weight loss programs.

Many people believe that these B12 shots cause weight loss.  They can help contribute to weight loss but they do not cause weight loss. What these shots do is that they help metabolize your fat and protein, which produces energy to lose weight.  One of the side effects of the shot is that is slowing down weight gain, which makes it desirable for dieters.

Tons of people struggle to lose weight, especially as they get older. When you get older, your metabolism slows down drastically making it more difficult to lose weight.  People always want a quick fix to help them with their diet and will believe anything when it comes to losing weight.  A vitamin B12 shot would seem appealing to most, however when you do your research, you’ll learn that unless your body is deficient in this specific vitamin, chances are nothing will happen.

Instead of going for weekly injections, why not eat a well- balanced meal that is rich in nutrients?  Try eating yoghurt, salmon, eggs, turkey, seafood, lamb and lean beef.  All these foods are very high in vitamin B12.  Don’t eat these foods for weight loss, but rather eat them for an added boost of energy.  This boost of energy may even motivate you to go for a walk, run or enrol in that exercise class you always wanted to try.
