I agree that you are placing too much emphasis on labeling your 'diet'. Who cares if the 'vegetarians' don't like it if you eat meat sometimes or if the 'vegans' hate it that he has the occasional porterhouse?
4 years ago (age 3
I was 4'11" tall and weighed very close to 325lbs. I was 'perfectly healthy' until I had a stroke. Then I got serious about my health. I had the same revelation, I obsess over the food I feed the cats and weight every moral but my own set was awful.
Losing a large amount of weight isn't about 'dieting' or finding a 'diet' that you like or about going vegetarians or vegan or 'going on Atkins'. If you completely cut out ANY food group you'll lose weight because you'll be cutting calories by not eating that food. No meat? Less calories. No carbs?.... less calories. Low fat? less calories. Those diets aren't sustainable (for most people) for life and for a morbidly obese person this change needs to be for life or weight will start to creep up again.
I wouldn't even worry about him losing weight. I followed 2 basic rules. Portion control and clean food(very subjective term, I know). I ate 1.5 servings of everything at meal times (remember, I was 320+lbs so my body used a LOT more calories to move my bulk around). Even after losing a majority of the weight I still have to weigh my food. I have a seriously skewed version of serving sizes. What *I* think looks like a cup of rice is way more like 2.5 cups when measured. Since the scale is always on the counter for cat food, it's no biggie to toss everything on it before eating.
Clean food, what I mean by clean food is little to no mechanical processing. No frozen meals, no boxed mac n cheese, basically whole foods I cook myself. That's not to say I NEVER eat potato chips, cheetos, Doritos, etc..' but they are an exception and not something I buy often and now I don't eat the entire bag in one sitting. I'll eat some and take the bag to work for the guys to finish at lunch. I eat ice cream every night, but only 1/2 a cup and I make it myself so I know it's without crap like high fructose corn syrup and other crap. Cream, whole raw organic milk, less sugar than the recipe calls for, and real fruit. I eat mac n cheese but it's not orange powder or cheese 'product', it's real cheese, whole raw organic milk, and whole grain pasta. I used to live on diet Pepsi, now it tastes like chemicals to me. I drink filtered water and a LOT of it.
Following those basic rules I set put to be HEALTHIER and weight loss was a very nice side effect. By the BMR rules I'm still considered over weight but I lost almost 2/3 of my body weight and I'm quite comfortable where I am.
