Some of the new decorations.
My wife is redecorating our home and one placque now hanging on the dining room wall says:
A good motto.
And maybe, if you time it correctly, eating your dessert first may allow you to not eat as much in total. Maybe you could have a piece of angel food cake, topped with a few fresh strawberries and whipped topping. But the key here is that you eat the dessert 20-30 minutes before the rest of the meal. Then, after finishing the dessert, you finish cooking the main course. That will force you to slow down, fully enjoy the food, and give your stomach a chance to send the "I'm full" signal to your brain.
But the motto on the placque really is just telling you to make sure you do the things that you really enjoy. Take time for yourself. Go on vacation--even if you do nothing more than stay home, turn off your phone and ignore your pile of school work. Drive the slow route to work and enjoy the different scenery. Read a book for pleasure.
And make room in your budget for dessert. The easiest way--and what I do every day--is to decide what you want for dessert, and log it as soon as you make that decision. That way, you have already deducted those calories from your budget, which gives you your remaining daily budget. In essence, you are eating your dessert first. And when you do this, you will be able to have that dessert and stay within your budget.
I like desserts. I generally eat them after dinner, as my evening snack. We generally eat dinner at 5:30ish. My dessert is usually about four hours later. That spreads out the food, preventing me from feeling over-full, and gives me a nice snack a few hours before going to bed for the night. My preferred evening dessert/snack is either an ounce of almonds and an ounce of dark chocolate, or a carton of yogurt mixed with some whipped cream and topped with some nuts, chopped dark chocolate, and coconuts. Both are about 300-350 calories and have more fat and protein than carbs which takes me through the night very well.
So, eat your desserts! Enjoy the sweet side of life. (Just make sure you log it.)
