this isn't a rant aimed at you, just loads of people have been asking the same, and I feel really strongly about this.
You must take all three sachets. The lipotrim sachets are the minimum possible requirements you need before your body goes into starvation mode. They are the minimum you can take in in order to cope physically with everyday life and to ensure your brain functions properly. If you knew someone was eating food of less than 300 calories a day it would be a major concern. Your pharmacist and the video should both be clear that missing packs is a big no no.
The least it will do is cause lack of weight loss.
Sorry to keep going on about this, but I have a friend who became hospitalised due to missing packs. She was seriously ill for quite a while. This is the reason it is medically controlled.
Please please everyone take all your sachets. It doesn't matter whether you are hungry or not, they aren't designed to satisfy hunger, they are your medecine to help you get better. If you were on anti-depressants you wouldn't think "I feel happy today" and stop taking them, or if you had a broken arm, take your cast off because it felt better. Please follow the plan properly!
Sorry, lecture over!
