How Different Diets Work

There are so many different “diets” out there. So how do you know which ones actually work?

Frankly, they all CAN work. And they all work for the same reason: a caloric deficit.

If I sound like a broken record, its because I really want to drive this point home. To lose weight, you need to be in a caloric deficit.

There are going to be people out there who claim that they began eating keto and have lost weight without being in a caloric deficit. Does it sound too good to be true? It should…because it is. You cannot lose weight if you are not burning more calories than you consume.

People like to try to find the “secret” to weight loss, but it truly is that simple. At the end of the day, for ANY of these diets to work, they have to put you into a caloric deficit. Plain and simple. Some might have other health benefits, but when it comes to weight loss, none of them hold any kind of secrets.

The best diet is the one that keeps you consistent. If cutting carbs out of your diet sounds absolutely miserable to you, then you shouldn’t do keto. Is the idea of counting macros and calories torturous for you? Maybe Weight Watchers can help by taking all the guesswork out for you. It totally depends on your preferences.

You don’t need a specific “diet” to lose weight- you simply need to accomplish a caloric deficit. You can do that in any way that works for you. But different diet methods might help you to accomplish that goal. Look at them as tools to help you get there. And like any tool, one might work better than another for YOU.

Don’t worry about Lily claiming she ate the same exact amount of calories, but cut out sugar and lost 50 pounds. She doesn’t know what she is talking about. Silly Lily.
