pounds and inches, it's the foundation of hcg. Also, you need to understand P3 (no fats, no sugar, re-introduce foods into your diet SLOWLY to watch for gains which means you have a sensitivity to that food.) Also p4 adding carbs and sugars back in, but again it's going so slow! You will be on the scale everyday, it's something you have to get used to doing 1st thing when you wake after going to the bathroom.
So your questions! Yes you have two loading days of foods with high fat content. You can also eat foods that you think you'll miss too . However you will have 40 days of VLCD and then 72 hours of no hcg then move into p3. You also need to skip a day a week (if your using rx grade) to avoid immunity. After you complete your forty doses, you move into p3 which is where you stay for a minimum of 3 weeks (21 days) then move to p4 for 3 weeks.
You need to have 6 weeks between 1st and 2nd round then for each round add 2 weeks to the break. You can stay in p3 for 6 weeks if you don't want to go to p4 a lot of people don't want to worry about gaining and finding out what they are sensitive too when they are just going to start a new round. And most eat that way for life maintenance too. Make sure you take measurements and pics every week so you can see your progress! Most important advice I can give is this is protocol and not a diet you can fall off a diet and come back again but with the protocol you can't do that without major set backs in weight and you will not reset your hypothalamus. I hope I hit all your questions!
