Caloric deficit is how you lose weight
Intermittent fasting is good because it limits how long you get to eat in a day therefore typically eat less food in a day
Eating mostly protein based meals is important when being in a deficit to maintain muscle mass and as well as being more satiating than other macronutrients.
Liquid calories are one of the biggest reasons for eating too much, avoid sugary drinks. Drinks that are okay are water, high protein drinks, and of course calorie free drinks that use stuff like aspartame
Think of the feeling of being hungry as really being the feeling of fat in your body being burnt for energy
Ephedrine and caffeine can help
Exercise helps achieve a deficit too
Easiest way to maintain a deficit is counting your calories of course but is far too complicated for some people
