With a busy hectic schedule, it sometimes feels like a miracle if we manage to get enough sleep, eat balanced meals, and squeeze in time for exercise. But did you know that there's an optimal time to do all these things? Get the facts and start scheduling accordingly!

The best time to eat breakfast, lunch, and dinner: You should always eat breakfast within an hour of waking up. About 4.5 hours after that, you should have lunch, and a couple hours after that, dinner. If you delay these times, you're going to be hungry, and the hungrier you are, the more likely you are going to cheat and eat fatty junk food. According to Dr. Oz, the big rule of thumb is that you need to have dinner more than three hours before you go to bed, so that you aren't going hitting the hay with a full belly of food that hasn't been properly digested.

Best time to weigh yourself: Weighing yourself first thing in the morning will provide you with the most accurate read on your weight, but if the morning doesn't work, make sure you weigh yourself at the same time — and on the same scale — to keep things consistent.

Best time of the day to go grocery shopping: Heading to the grocery store at 10 a.m. is the best time, since you'll still be full from breakfast. If you go grocery shopping when you are hungry and blood sugar levels are low, it impairs your judgement. If you're hungry while food shopping, you'll be more likely to buy unhealthy sugary or fattening treats.

Best time of day to work out: Morning! One study found that subjects who were put on a high-fat diet and worked out before breakfast gained no weight after six weeks, while those who worked out after breakfast gained three pounds. When you exercise in the morning, you kick-start your metabolism and burn more calories throughout the day.

Best time of the day to visit the doctor's office: If you need to go to the doc's, it's best to schedule your appointment first thing in the morning. Not only will this decrease your waiting room time since you'll secure the first appointment of the day, but it also means you won't be overly hungry if you needed to fast before a morning lab test.

Best time to boost your metabolism: The best time to rev up your metabolism is at 8 a.m, since you'll be getting up, weighing, yourself, and hopefully exercising. One of the easiest ways to boost your metabolism first thing in the morning to to drink a cold glass of water.

Best time to cheat on a diet: If you want to sneak in one or two of your favorite foods on a particular day, there's actually an ideal time to indulge — and it might surprise you. When it comes to carbs, celebrity trainer Bob Harper says the best time to enjoy carbs is for breakfast, and according to Dr. Oz, the best time to eat fats is at 10 a.m. Both work to fuel and energize your body, but when you enjoy them in the morning, you have ample time to burn them off all day.
