I lost weight through prescription diet pills first. These helped maintain my energy and I didn't experience the effects you describe during this phase. (Lost about 60 lbs, gained 10 back.) After that, I went on Weight Watchers and lost some more. (Lost about 20 lbs, gained 10 back so far.) This time, I did experience what you seem to be. I ended up reading a lot and deciding that carbs were the culprit. A combination of caffeine (which I previously avoided) and a lower-carb diet have help even out my blood sugar and keep me able to focus at work, and even sometimes get some programming done in the evening. By "low carb", my wife and I look at the carb-to-fiber ratio and look for something 10-to-1 or lower, heavily favoring things that are 5-to-1. It cuts out a lot of things like white bread and a lot of snack foods, but I've found plenty that I enjoy on the 'ok' list and I feel better and more satisfied. My 10 lb gain since stopping WW has been very slow, but it's still happening and I'm reconsidering Weight Watchers again. It seems to be the easiest, most accurate way I've found so far to track what you're eating and know when you're going wrong. Their new plan seems to shun sugars and reward protein, which is great for me, so I'm expecting to like it... And actually not change my diet much, but just how much I eat of it. In short, I addressed it by watching my carbs.
