YANBU. At all.
Bit of background - I'm 6 foot tall, and played rugby in school/college until a knee injury put the kibosh on that. So I'm never going to be "skinny" by any stretch.
After my Dad passed, I put on weight. Lots of weight. Ben and Jerry were amazing therapists, but terrible fashion stylists.
I tried a couple of variations on low-calorie diets, and sure enough, had some success, but never anything lasting - I was always too hungry on such restrictive diets. I'd plan for the day, eat well... and then gnaw my fingernails off, desperately trying to avoid "just another nibble". I failed. Massively.
In November 2012, I discovered the ketogenic diet (aka Atkins). The basic principle is less about lowering carbohydrates, but lowering insulin. Insulin tells the body that sugars and starches are present in the body. These energy sources can be converted to energy faster than fat, so insulin processes the sugars and starches, and tells the body that any fat eaten isn't needed right now, so store it somewhere. Like the tummy and bum (grr).
A study by Stanford University confirmed more efficient weight loss was obtained from low-carb diets as opposed to standard diets - subjects on the low-carb diet ate as much fat and protein as they wanted, whereas the standard diet was calorie-controlled and lower in fat. The low-carbers lost nearly twice as much weight, as well as lowering triglycerides (fat storage molecules) and blood pressure levels twice as much as the standard dieters.
I read up, did my research (infographic linked), and put it forward to my partner at the time as something to do together. After a quick browse, I stocked up the fridge, and then in what felt like the blink of an eye, went and lost 78lbs in under 6 months. I started being able to exercise again, I got back in to my old clothes, and then some (my new wardrobe looks magnificent, by the way).
The widespread dissemination of Atkins falseties is cute. Dr Atkins died in hospital with an obese BMI, true - after slipping over on ice, cracking his head, and putting on 4 stone of fluids while in hospital, in intensive care. My former partner's mother (OH JOY ANOTHER MIL-BASHING!) told me she thought the diet was unhealthy and would damage my (read: DD's) health. I pointed to my waist and said "I've taken 8 inches off there. I get a feeling I've made up any 'damage' I might have done to my life expectancy".
I'm not saying standard dieting doesn't work - quite the contrary, standard dieting works, if you can stick to it. Therein lies the problem.
My current DP has joined me in going back to the ketogenic diet, "on a trial basis". I drew up a meal plan for the fortnight - curried chicken breasts with mushroom, bacon and eggs, roast pork belly with cauliflower cheese and spinach, Caprese salads, low-carb breads - gathered supplies, and started cooking. At the end of the first day, I heard the magic words, "I tell you what, lunch was great, and I feel really full. I'm not sure I'll want anything else till late tonight!"
Mission accomplished, I'd say.
