The last meal of the previous day should be between 8pm to 10pm
While fasting, you should have 1 or 2 cups of coffee during the morning to further activate the fat burning process1.
During a fat burning diet, the amount of protein consumed should be high. It should be between 100-140 grams protein max2. This is because protein makes you feel fuller and therefore you eat less(among other benefits).
During the feeding period (after lunch, between 2pm to 10pm), as prescribed by the diet above, eat plenty of veggies.
Non guilty snacks that help quite a lot with dieting include diet cola (I prefer Pepsi Max), Diet Jelly (tastes amazing and makes you quite full) and some variations of Konjac Noodles (basically no calories)
