Fruit juice
The reason you shouldn’t drink fruit juice is mostly because of the sugar content. Even if it’s freshly squeezed or pressed fruit juice, the natural sugar content can be enormous. You need energy in the morning, not a “sugar crash” caused by falling blood sugar. If you want orange juice, don’t squeeze more than one orange. Preferably, drink a glass of water and eat the orange, fiber and all. If you really want to improve your health and daily performance, cut out sugar altogether.
Toast with jam or sweet marmalade
Toast with jam should be avoided because it is pure carbohydrate. If you’re going to eat toast, top it with protein, in the form of an egg, with or without bacon, sausage or another non-processed meat. Many people find that a good solid breakfast of egg and bacon gives them the energy they need to start the day. If on a high fat, low (or no) carb diet, there are breads that can be substituted for grain breads (and toast), particularly those made using coconut or almond flour.
