It’s always a good idea when you find yourself reading results/claims from other people to remember that we are all different. Things would be much easier if we could all just know what the right diet is. We could all do the same workout and be guaranteed results…If it were only that simple.
Be willing to try new ways of eating and exercising. Gluten doesn’t affect everyone the same way. A more vegan lifestyle works well for many. Paleo is useful for lots of people. If what you’re doing now clearly isn’t working why not try something new?
