<human>: Hi Loseit,

About a month ago I hit 345 after being 339 for years. It was the motivation I needed to get me ass in gear and finally eat right and lose weight. I haven't had a single cheat meal in a month. I only drink water and haven't had any bread, potatoes, or rice in a month either. I drink 2 Herbalife shakes a day and 1 normal (not unhealthy) meal. Minimal semi-healthy snacks throughout the day. 

My BMR is 2793. I've been eating about 1,000 calories per day. The past few days I've gained weight! Yesterday I had 2 Herbalife shakes, grilled chicken, green beans, and broccoli and tons of water.....today I'm up 1.5 lbs. This is driving me insane because even when I was eating Taco Bell for 2 meals a day, I maintained my weight. Now I've drastically changed my eating habits and there is almost no change. 

I still am motivated to lose weight. I still don't want to cheat. I just want to know, How I can possibly be gaining weight after burning significantly more calories then I take in per day?

Here are the nutrition stats for Herbalife for those unfamiliar:

Can you give me the gist of the text in a nutshell?
<bot>: Healthy eating for a month. Losing some weight, then gaining most back. For the love of god, why?
