Please choose the correct ending to complete the given sentence: Food and Entertaining: [header] How to boost your metabolism at breakfast [title] Eat breakfast within one hour of waking. [step] You have probably heard the famous saying that " breakfast is the most important meal of the day, " and it's true! That is because when you wake up, you likely haven't eaten for 8 to 10 hours. Your blood sugar is low, and so are your energy levels.

Ending1: You need to " break " the " fast " within one hour of waking up. A healthy breakfast will jump start your metabolism and your day, but waiting too long to eat can actually slow you down. Ending2: This is why it's important to eat breakfast within two hours. The slow-digesting low blood sugar causes your metabolism to slow down considerably and prevent you from resting for too long. Ending3: This can cause you to feel burnt out pretty quickly. Try eating at least 3 whole meals in the morning and measuring out 1 cup of greek yogurt or suet. Ending4: During a healthy breakfast, you're more likely to feel full at a certain time. You may have time to grab a banana or yogurt at dinner, however.
