As a former skinny girl who became a fat girl when I had DS1 18 years ago, I struggled for many, many years to get back to my ‘real’ body shape. I lost stones and then slowly gained them back every time, plus a little more. I finally realized that my body just wants to be bigger, for reasons no scientist, nutritionist, shrink, guru or doctor has managed to explain. Until they do, dieting is a fool’s game. I will never win a war with my own body. Now I focus on staying super healthy, getting lots of exercise and eating quality food. I eat when I’m hungry and don’t worry about calories, fat grams, carbs or points of any sort. But I do avoid artificial sweeteners, transfats, high fructose corn syrup, highly processed foods, etc.
Being slim is largely a matter of genetic luck. All of the mums on hear claiming thy stay slim by skipping breakfast or busy busier than thou are deluding themselves into believing their metabolic luck is some sort of personal virtue. I’m going to put this is caps so it can’t be missed. BEING FAT IS NOT A CHARACTER FLAW. It’s just a little extra tissue your body wants to hang onto for some unknown reason. It doesn’t mean you are lazy or stupid or undisciplined. Most of the fat women I know are on constant diets, eating little plastic pots of steamed vegetables and rice all the time. They are always trying to lose that weight and always denying themselves. They live their lives oscillating between being hungry (because they haven’t eaten) and feeling guilty (because they have.). It’s a crappy way to live.
My advice is to get your DC a little three wheeled scooter and take them out for walks with it. You will soon be getting a good workout jogging to keep up, and feel better for the exercise and fresh air. Stop worrying about your weight and start focusing on your health instead. Being healthy is an achievable goal at any weight. Being skinny, for some of us, is not. Fight the battle you can win.
As for the class thing, I think it works the other way. The world is unkind to fat people and people (especially women) granted thinness by nature are given more and better opportunities.
Don’t be hard on yourself. Your body made that lovely child and you should be appreciating what you achieved. Treat your body well and kindly and don’t worry about returning to your pre-baby body. Your life has changed now, and this is just part of the change. Good luck to you!
