Greetings everyone, i am 18 year old male, 175 cm, 95 kg. A few hours ago i have found this app called "My Diet Diary" and i gave it a try, thought it would erase some question marks about dieting i have, even though the daily calory budget and meal calory calculating are very helpful, (for example) I don't even know if the calories shown in calory budget are necessary for me to gain in a day, or simply if i have less calories than it says i win?
That was question 1, 2 is, I try to eat 3 meals which are definitely not fast food, mainly cereals, sandwiches with tomato, cucumbers, cheese, and random dinner every day (and 2-3 times minor snacks, almonds, nuts, apples, banana etc.) with fixed hours if possible, but a friend of mine said that i wasnt used to such diet, (before this idea i always ate what i wanted and mostly unhealthy food including a lot of snacks) and anytime i felt hungry, i should simply eat apples, bananas, etc. because a "direct" pass into strict diet was unhealthy and the body would deposit the food i ate as fat because it would think i was starving and that would not help me, is this true?
Third and last question is related to first one actually, but i'll ask anywyay: Is the idea of "minimum calories i can get in a day" unhealthy or somehow damaging for me? Regardlesds of the daily calory budget?
I appreciate your help and time, these are major questionmarks in my head and would relieve me greatly if answered accurately, I do apologize if i wasn't clear enough, I tried my best.
