And you can't stick to it. Who can? Food was meant to be enjoyed, even while trying to lose weight.
Whether you cut out the carbs, or the sugar or have a food allergy, whatever you eat should taste good. The reality is weight loss comes down to simple math. Eat fewer calories than you burn.
Now will your body do better eliminating certain foods, yes it can. Certain foods can help you feel fuller longer and also help curb cravings. But the bottom line is that whatever you do has to work for you and your lifestyle.
I was once told to try and make every meal a "Number 10" meal. Tasty, scrumptious something you look forward to and savor and something you wish you had more of. If you can eat something that is tasty and keeps you full longer you will stick with your plan.
Next... drink water, lots of water. It's good for you, it keeps you hydrated, and also some times when you think you're hungry, you may be just thirsty. Not a water drinker? Then add some lemon, or some flavored sugar free stuff to it. There's always a way to increase your water intake.
So no matter what plan you decide to go with or if it's just your own, just make it the most tasty, fun, incredible food you can.
Enjoy, enjoy, enjoy!
