My relative advised me to count calories so as to help me shed pounds: so I asked him “how many calories do I need to lose weight?” and he informed me that I need to burn double the calories that I eat to stimulate safe weight loss. He also said to take b12 shots for weight loss so I will possess the extra boost and increased metabolic rate. I was a bit cautious on calorie counting because I have read somewhere it doesn’t really work and it’s not really necessary. Weight loss can be confusing at times.
