I bring my lunch from home sometimes, and that is sometimes a left over from the previous nights dinner. We at a lot of rice...so obviously sometimes the dinner ends up being a rice and curry-type dish. The problem is that rice makes you sleepy...especially when you eat it at lunch!
That's a problem for me at work, so the idea is to avoid starchy foods at lunch. I don't get a lot of time to move around, so I need to do what I can to keep my weight loss diet plan whatever way I can.
That means taking simple steps like avoiding starches at lunch when possible. Even if you eat out at Chinese or Thai food restaurants, it might be a good variation to avoid the rice and just eat the dish directly.
