Every body is different.
Id work out twice as hard, and twice as often, as some of my former martial arts students.. and my muscular development was twice as slow, and less developed.
I also know people who can eat all day, and not gain... where as I know others, who eat one or two things... and get instant bulge.
This has to do with body and brain chemistry, digestion / absorption efficiency, food allergies (many people dont even know they have), Youth (young bodies heal, develop, and shed mass much quicker), and much more. Youth also tends to be IGNORANT... thus you see these kinds of idiotic posts.
If you want to lose mass... Eat more veggies, cut back on sugar, less starches, and Drop almost all the FATS. Most especially the man-made stuff that clogs your arteries. Trans-fats, High Saturated fats, Hydrogenated fats. Look on the packages. Note the amounts and the kinds of fats.
Fast food and cheap food, is most likely to have high saturated fat content, as well as man made fats which do major internal damages over time.
Choose lean meats, like Chicken... over high fat meats..such as burgers and sausages.
Lose the high fat salad dressings.
Cease the Ice Cream.
Stay away from nuts. Eat lean protein instead.
Reduce portion sizes gradually... and wait an hour after finishing, even if you feel hungry, before eating more.
Eat lower quantities of less foods more often... rather than in large mass lumps.
Dont starve the body of nutrients or stop eating. This trains the body to save the food as fats, because it never knows when the next meal will come.
Exercise.
Dont exceed a certain level of calories intake.
If you Pig Out often.. that shows you have probably have a loss of control / compulsive condition / or have a psychological issue. That may need other methods to correct it, such as medication, counseling, etc. Or it may be self fixable, by putting effort into Internal Strength development: Start daily meditations, and start to gain control of the deeper inner mind, soul, and thus body.
No more time for the rest. Might post more later.
