Weight gain is not on my list of goals! It was all in the abdominal area, it seems, so that makes in really a problem I do need to solve, thanks to the correlation between visceral fat and chronic illnesses.
There have been many changes in my lifestyle - from increased exercise to the reduction of carbs, and then some. I believe this made my body not know if it was hungry or not - it just decided to eat when there was food, because it no longer had immediate carbs and it never 'knows' when it's going to need to go for another run.
Because of this, I have found it necessary to account for calories in a new way.
I have taken to eating low-calorie high-water foods (i.e. vegetables) in extremely large amounts. These are accompanied by an "adequate" portion of protein and fat.
For instance, when I started this low-carb thing, I would do something like a 2-egg omelette with a handful or two of spinach for breakfast. This is often times just too much for me in one sitting. Contrast this to today - I shredded and squeezed the water out of 2 summer squash (yes, two whole summer squash), combined with an egg and some garlic, cooked in coconut oil, and served that with mustard. This provided a very satisfactory nutrition profile of just 200 calories with 18:28:55 protein:carb:fat as well as 30% of my daily vitamins and minerals. It left me full but not stuffed like the 2-egg ommelette.
So I was overeating because I wanted to ensure I got sufficient nutrition, but it turns out that less is more for protein, and more is less for vegetables, so just eat those veggies up. But another aspect of this overeating was because my body was adapting to the changes, leaving me occasionally tired when I ought not to have been. I thought it would be smart to fix this by eating before doing anything demanding - this was not the answer. Yes, I COULD eat a large lunch before going to work, but chances are someone will have made a large dinner by the time I get home, and that is too much food. I am much better off with a small lunch, an emergency bag of nuts, and eating my fill when I get home.
I've done this only for a few days and my weight has started to go down again. I hope that it will continue.
