I started these shots over 6 years ago and every morning I have one with my Celsius energy drink. I lost 30lbs in 6 weeks without any other changes. 6 years later I haven't gained a pound back. 42grams of protein in one shot is a nice dose(powders are usually 20 grams) and unlike powders there is no mixing and blending.. grab it out of the fridge and drink it as I start my day. Someone asked Dr.Oz on his show what the secret was with weight loss and keeping it off. he said 30/30-30 grams of protein within 30 minute of waking up.. "gives your body enough fuel for the entire day..." so true.. but you have to do it within 30 minutes of waking up. I struggled with my weight since I got out of high school. 6 years ago I dropped the weight with just one shot of these a day and have never gained a pound back. I weigh what I weighed in high school and that was 30 years ago.. I love this product.
