Why bother with the 'quick boost' - it's fallacious anyway. You need plenty of water, but not THAT much. Cut down the water to 2 litres, and cut down the coffee. My diet is this: awakening, glass of water. Breakfast: fruit juice and a pile of fresh fruit, e.g. 1/2 a melon, a mango, grapes, whatever, a different selection every day, as much as I can eat.
Elevenses: water followed by coffee and dark organic chocolate with 85% cocoa solids for flavonoids and serotonin for energy and good mood.
Lunch: Water followed by huge salad with rye bread, 1 avocado, tomatoes, dried tomatoes, olives, cottage cheese, radishes, cress, lettuce, alternating but always with an avocado for brain function and omegas, and as many different colours as possible for a variety of minerals.
Evening: veg soup, changing ingredients every day but always with garlic, pulses and greens. snack before or after the soup on porridge oats cooked with water, adding nuts, seeds and bilberries or blackberries, OR, oatcakes with tahini or humous and chives.
Water can be taken in the form of herb tea, great in winter when you don't always want something cold to drink.
Walnut milk is a healthy, DELICIOUS and more slimming alternative to cow's milk than soya.
And make sure that what you eat is ABSOLUTELY DELICIOUS. Life's too short for suffering.
