The famine reaction is an automatic response of your body to losing a large amount of body fat.

Quoting from myself here Katerina.
Secondly let me quote from a book i'm currently reading, which is not about what i said or didn't say but more to the point of what matters here:
The book:
Don't Go Hungry for Life by Dr Amanda Sainsbury-Salis who is a scientist who has made the study of medical science and obesity her life's work. She was obese as a young woman so its not just a job but persona. This is her second book. Her first was called The Don't Go Hungry Diet. She has a very credible list of credentials behind her. in 2008 she was selected by the International Association for the Study of Obesity to the be the chairperson of the International Conference for sex and obesity in Bangkok.
"Chapter 3
How much weight do you need to lose?
…"In this chapter i am going to explain the the acid test that will reveal exactly what weight you're biologically meant to be. But first i'm going to explain how you can get a useful ballpark estimate of your ideal weight and size based on crude measure of body mass index and waist and hip circumference. This information is based on estimates drawn from medical research as to which values of BMI and waist or hip circumference are healthy for
most people [my emphasis]. I'll then show you how to narrow down your search and pinpoint the optimum weight for you.
"
Get a ballpark estimate of your ideal weight and size.
"One way to get a broad estimate of your ideal healthy weight is to calculate your body mass indices.
…"current research suggests that having a BMI of 25kg/msquare or above puts you at significantly higher risk of hypertension, metabolic disease such as type 2 diabetes, cardiovascular disease. The greater your BMI, the greater your risk…"
"every time i punch these numbers into my calculator, i'm acutely aware of the fact that, at my usual weight of 65kg, i'm 1.3 kilos overweight according to the WHO! Its important to know that BMI is not the only determinant of your ideal weight or metabolic health, and that BMI is not a validated predictor of disease risk in children, in adults who have not finished growing, in adults who are naturally very lean or very muscular, in people from certain racial or ethnic groups or in adults over the age of 65. This is illustrated by the fact that many olympic atheletes have a BMI that places them in the overweight or obese category as definite by the WHO, although metabolically they are extremely fit. On the other hand, some people with a BMI in the normal range store excess fat around the midriff , and this places them at significantly higher risk of metabolic diseases.

Waist Circumference
When it comes to being healthy, its not so much ow much you weigh but how much fat you have on your body and where you store it that counts. Carrying too much fat around the midriff, especially in the visceral space around the organs such as the intestines, liver and pancreas (belly fat) is linked with significantly higher risk of preventable lifestyle disease such as diabetes, heart disease and certain cancers. Research shows that most Caucasion and Asian women with a waist circumference of 80cm or over and most Caucasian men with a waist circumference of 94cm or above are at significantly greater risk of developing preventable lifestyle disease and metabolic complications, regardless of how tall they are … For women and men with waist circumferences greater than or equal to 88 or 102 cm, respectively, the risk of metabolic complications is even higher."
…

Waist to hip ratio
"…in a review i recently co-authored for the International journal Obesity Reviews, several epidemiological studies suggest that having ah ugh waist-to-hop ratio (that is your waist circumference divided by your hip circumference_ is a better predictor of death from cardiovascular disease than having a large waist, regardless of your waist circumference of how much belly fat you have. In brief, if you're a sufficiently pear-shaped, your risk of dying from metabolic disorders such as cardiovascular disease may be less than that of most people who are more apple-hspaed, even if you're larger overall.
"
Are you an apple or a pear
"To calculate your waist to hip ratio, divide your waist circumference as determined above by your hip circumference
...
" In terms of metabolic health, research suggest that if you waist to hip ratio is less than .8 for women and less than .9 for men, you're doing well. "
There's nothing like a regular check-up
BMI and waist and hip circumference are helpful tools for estimating and comparing the overall metabolic health of populations, butr are not accurate tools for determining the health of individuals. To get an accurate assessment of your own metabolic health and risk of ideas, see your doctor for a full check-up.
Fine-tuning your weight and and size targets….. you'll have to read the book if you want to know what she says. The thing is, i'd have to type too much more but for the sake of this to and fro with Katerina, i think i've said enough about where i'm coming from.
But she does summarise the chapter thus:
As a first step towards determining your ideal healthy size and weight, its helpful to take stock of how you measure up against research into metabolic health. If your BMI is over 25kg/m squared and your less than 65 years of age, then aiming for a BMI of 24.9 or less is a prudent move. Additionally if your waist circumference is 80cm or more for Causasian or Asian women […] then stripping weight until you waist falls under these cut-offs points is one of the best things you can do for your long term health and longevity. Every kilo you lose will result in a loss of approximately 1 cm from your waist.
