Peridot,
Your counsellors reaction is quite interesting actually. Our counsellor has always warned us that after a period of technical starvation your fat cells retain their memory, and your body prodcues a hormone called Grehlin. This essentially encourages your body to restore the fat it has lost through famine, which is why for a certain amount of time post diet you should be very mindful of your intake. I always imagined it like my body grabbing and storing the fat from my food in preparation for the next famine. Interesting that a survival instinct could be so detrimental to health but the human body is a complex thing.
Our counsellor said that you should really try to be as careful as you can for the 12 months following a starvation state, and after this time your 'fat cell memory' as such is re-set and you can be a bit more relaxed. I don't think it has to do with calorie intake as such - more fat content of your diet which you should be careful of.
This article tells you a little more about grehlin and its effects....
The Gut Hormones: How You Know its Time to Eat and When You’ve Eaten Enough
Grehlin
Another component of the energy reserve regulation in the body involves some of the hormones that control feeding and appetite, which are located in the gastrointestinal tract, including the pancreas. Specific hunger signals trigger eating, while satiety messages inhibit appetite. These distinct hormones are often referred to as the ‘gut hormones’, of which grehlin has been proposed to be particularly associated with obesity (Druce et al., 2005). Grehlin, secreted by the stomach, plays a major role in appetite regulation. It is referred to as the ‘hormone of hunger” and has an opposite association to body mass index (Druce et al., 2005).
Working in a positive feedback loop, high levels of grehlin during a fasted state promote increased food intake, while lower levels of grehlin are observed after eating a meal. However, when obese individuals lose weight, this often results in an elevation of grehlin, also promoting food intake, and thus may be a physiological reason there is difficulty in maintaining the new found weight with dieters. In addition, it appears that food does not suppress grehlin levels in obese individuals, again contributing to overeating.
