Invest in nice, quality Tupperware. That's my trick. I have lots of beautiful, cute, fun little jars, containers, and the like. The point of having these beautiful little storage containers is that I have build in portions, I can pack small snacks, and they are small enough that I can eat them anywhere and stay full throughout the day instead of gorging at meal times. I also have some cool water bottles and to-go cups. I keep them filled with water, tea, or black coffee. I've been told that i'm weird for just drinking hot water, but I find it so calming, satisfying, and comforting.
Tip #1, too (hehe, punny):
Try your best not to eat anything heavy after 6 pm. If you need a little snack later on hit up your friend the fridge for some sexy fruit or veggies. a banana with chia seeds a drizzle of honey and a dash of plain yogurt is seriously as good as ice cream. no, really!
along with this tip comes the usual tip about downsizing your plates. I go one step further and use half seized utensils. This makes everything seem more like a delicacy and I tend to savor it and put my spoon down between bites (i don't really like forks. I know it's bizarre. feel free to tease me about it haha. i laugh at it myself).
Welp, that's all, folks. Hope it's helpful. I find it makes a HUMONGOUS difference.
Smile! You deserve it
