Since this is Lesson 1 it will be short and sweet.
To lose fat (not weight–FAT) you must make it sustainable. As in, you can’t jump on a fad diet, or think you can do P90X in 90 days and be a god. Well, hold on. You can do all that if you like. It won’t work. You’ll eventually put the fat back and probably some more too. You’ve heard this same shit everywhere before, so it’s nothing new.
What is sustainable? I don’t know you. I don’t know what’s sustainable to you. I know what’s sustainable to me. You must define stability to you. What can you put up with and for how long can you put up with it? Can you eat 500 calories a day for 6 months? Can you start training for a marathon and keep it up for over a year? These sound drastic, but are doable.
So the first thing, before you go on to any other lessons, spend some serious time in that noggin of yours and really be honest with yourself on what you can manage on a daily/weekly basis. I don’t say monthly, because there is no monthly. All you need to do is focus on daily and weekly. This will make more sense in later lessons.
Why am I making such a huge deal out of this? Because you’re not “going on a diet” you’re not “doing P90X” you’re going to change your entire life–for good.
So stop being a little bitch and figure out what you can sustain. You’re the only one who can.
