I started using this -- two tablespoons in the morning and two in mid-afternoon. I have lost 40 lbs in just a few months and plan to lose another 15 to get to my ideal body weight of around 210. I am 6'2" tall, age 58. I workout regularly 1 hour of cardio 5 x a week and 30 minutes of weights 3 days per week. This is an amazing supplement.
