Subsequent rounds of the HCG can be very  different from the first.  When we are heavier, our body has the ability to  "choose" which fat cells will be metabolized with the least negative affect on  the system.  If the circulatory and nervous systems of the body are taxed, the  body will innately choose fat cells that contain less harmful toxins to be  metabolized.  When we are heavy, this task must be pretty easy.  However, since  our bodies are in survival mode all the time, asking the body to move into  deeper levels of toxicity before it is ready, will cause the system to halt the  release of stored fat, in an effort to protect the  body.
The second and third rounds of HCG  will require that the body dig into fat stores that might possibly contain   metals, pesticides, preservatives, chemicals, dental materials, vaccination  residue, synthetic drug residue . . . not to mention any causitory elements like  yeast, mold/fungus, virus, parasites, and  bacteria.
The body is so good at "hiding"  unwanted elements in the fat cells when it does not have the resources or the  ability to move it from the system.  And, to maintain a survivable level of pH  in the interstitial fluid, the body will retain water (even from the intestinal  tract) to buffer the cells against the acid produced from the fat soluble  toxins.  So, here is a kindergarten analogy: 
1. We come  into this program in a deficient state. (plain and simple, we are all somewhat  acidic, toxic, and depleted) 
2. We ask the body to burn  stored fat for fuel.  (plain and simple, our fat is toxic and acidic  -   although, this fat does also contain nutrients as well)
3.  Since our body has to keep within a safe level of pH, the release of  acidic elements during the diet could force our body to use up more of it's  important vitamin and mineral reserves in order to balance and neutralize the  acidity.  
4. When B-Vitamin and Trace Mineral reserves  become depleted in the body, the adrenal glands begin to feel the stress, and  then kick into their survival mode.
5. Adrenals, when  stressed, make the body CRAVE simple carbohydrates in order to get quick and  easily assimilated foods into the system. Adrenals play a large role in the  body's ability to balance blood sugar. Think about it . . . an athlete coming  off the field will never crave a steak and broccoli . . . they crave hydrating  sugar/sport drinks, or simple carbos to load up their system again.  Remember,  this depletion is not about health, but about the actual "survival" of the  stressed organism (body).
6. So, when the  body becomes stressed (mentally, physically, and nutritionally) it creates an  overly acidic condition.  The body responds with the use of minerals and  vitamins to neutralize the acid.  The vitamin and mineral usage causes a  depletion which stresses the adrenals and thyroid, and the result can lead to  uncharacteristic cravings for sugar and carbohydrates out of the  blue!
7. It is important to alkalize our body  (green drinks, alkalized water, mineral supplements, etc)  so it doesn't have to  use it's mineral stores to create balance.  If we are already doing our best to  introduce alkalizing elements, then our mineral reserves won't get used up and  we have a better chance of staying in appetite suppression during Phase 2 of the  diet.
8. A depleted thyroid can play a part in appetite.  There are  elements in the HCG Phase 2 product that can be support, however, some  individuals would do well to seek out a natural thyroid supplement.  If a  participant is currently taking thyroid medication, they should seek the advice  of their physician to determine the correct dosage of their medication during  this time.  There are many good thyroid supplements to choose from.  Find a  naturopath near you, or go to your local health food store and inquire.  Our  thyroid gland is responsible for so many important physical and emotional  functions in the body and mind.  If ravishing hunger persists, seek out a  supplement to assist you!  All forms of Kelp have iodine which can bring the  thyroid back into balance.
9. Yeast, can play a role in  cravings as well.  This program is just like being on a yeast cleanse.  We are  eliminating sugars and starches, which feed yeast.  As the food supply for the  yeast begins to dwindle, the cravings for simple sugars and starches increases.   If we can resist the temptation, there will be a yeast kill-off, and the  cravings will subside.   Yeast can be a "hunger culprit" in later rounds of  Phase 2.  If yeast, mold or fungus has been an issue in the past, the body would  be well served by adding in Acidophilus or Pro-Biotics during this  time. 
How do I resolve this  issue?First, we have to start looking at the body as being  really smart!   If the body is lacking in a certain nutrient, it will begin to  search the system for alternatives.  The only problem with this, is that  eventually ~ other systems, organs, glands become depleted as  well.
We have not been taught to supplement our  daily intake of food with extra nutrition.  But think on this:  it takes 26  apples today, to equate the same nutritive quality of 1 apple from 1915.    It  takes 23 peaches today to equate the same nutritive quality of 1 peach from  1950!  This is disturbing to say the least!  Is it a wonder why we are all more  hungry most of the time?  The nutrients our bodies are craving cannot be  attained from just a single serving anymore.  It takes much more food to  overcome the deficiencies we face today.
It is  highly recommended that individuals get on a good B-Complex and a good trace  mineral support while in Phase 2.  This will help the body recover at a faster  rate, and supply the body with good foundational nutrition during this period of  rapid change.  These nutrients would be helpful in Phase 3, 4 and continued into  everyday life as well.  Our toxic nation is only going to continue to deplete  our bodies, our systems, organs and glands.  
So, supplement!!  Find a  good quality "food state" vitamin and take it EVERY DAY.  Find a good Trace  Mineral supplement and take it EVERY DAY.  Find a good B-Complex vitamin and  take it EVERY DAY.  Research higher pH water sources and drink ample 7.0 or  higher, filtered water EVERY DAY!!
