Will having pizza for lunch make me gain weight?

If I had oatmeal for breakfast, two slices of cheese pizza for lunch, and nothing for the rest of the day, will the pizza still make me gain weight, or will the not eating for the rest of the day make up for those calories?Will having pizza for lunch make me gain weight?
If this is like the first time in a week since you've had pizza, then you should be fine. A not so 'healthy' food now and then is good for you, especially one that does try to offer vegetables and proteins. You just gotta make sure to eat at all meals! Something, anything to give your body the energy that it craves. I mean, if you're really into loosing weight, the only way that you really can is by cutting off all processed foods. Go natural. Drink water. Make your own meals. And walk once a day.
You need to eat throughout the day. If you don't, then your body will keep the fat you gain from your pizza and store it away for "leaner times" because you starve yourself so often. Also, eat a bit healthier than pizza everyday for lunch. You have to eat vegetables, fruit, and meat too.Will having pizza for lunch make me gain weight?
You're supposed to eat during the day to keep your body running. The later in the day you eat the more chance you have of putting on weight... it won't be healthy, but eat what you want to! Don't become obsessed with weight!
Don't eat nothing for the rest of the day, squeezing calories like that will create a shock-reaction, that's when you damage your metabolism(and that's when your body can go on lockdown).
no, it will have no affect on you.. weight gain is a long process! Our bodies are programmed to cope with different eating plans, otherwise we would just not be able to live. Not eating for a day doesn't make you loose weight either, right?
you eat a slice for breakfast, lunch, and dinner if thats all and you still wouldn't gain anything, its simply keeping the daily calorie intake low.
You should be fine but there's no need to starve yourself.
