There are more than 2, but, here are 2 of my favorites:
(1) You Don’t Stick to Them.
Following a restrictive diet isn’t as easy as taking one pill every morning. Yet.
You’ve got to have three meals a day prepped and ready to go, or else you’re at risk to ‘break’ the diet. There’s no fluidity.
Life is fluid, not rigid.
I would much rather have you learn what foods to eat, and what foods to avoid, so that you can simply make the best choices available, based on what’s in front of you at that moment.
(2) You Do Stick to Them.
If you manage to stick to a restrictive diet for 30 days, you’ll probably feel great at the end of it.
But then what? Should you continue? For how long? 30 more days? 60? 180?
You’re stuck in the same box as you were above. Boredom and curiosity inevitable creep in. You’re human. Food is all around you. You’re not a robot.
Unless a certain food irritates you, as is the case with gluten for me, there’s no need to completely remove something from your diet forever.
Restrictive diets are nearly impossible to maintain long-term.
Small changes that you can build on are what stick and last.
