Since you are here you probably already tried a bunch of diet... and sometimes it's working for a short time, sometimes it's not working at all. Doesn't matter if it's a low carb, keto, carnivore, vegan, vegetarian, high protein or other fancy named "diet". One Law To Rule Them All: Thermodinamics: Weight loss is actually very very very simple It's about energy in and energy out. - If you eat more energy than you use, your body will store the excess energy for later in a form of fat. That is the state that we call calorie surplus, this is where you will gain weight. - If you eat less energy than you use, your body will use the stored energy (aka the fat) to function. That is the state we call calorie deficit, this is where you will lose weight. - If your energy in and energy out is equal then your body don't have to store and don't have to use the stored energy to function. Because you eat exactly that much energy. That is the state we call calorie maintenance, this is where your weight stays the same. In every fancy named diet has one goal. Put your body in a calorie/ energy deficit so it can use the stored energy. That's it. Of course those people always will tell you some fancy words, why is it working, why is it so cool. But there is a big problem with that: It didn't fit in your lifestyle, because it's just a PDF diet that someone who has completely different life made without knowing anything about you and your lifestyle. So even if you can do it for a short time, eventually you will stop because you won't like it. Because you can't sustain it in long term (because it's impossible since it's not specific to you) and when you stop with that diet you will go back to your old habits and gain it back. I have to tell you something very important: This is not your fault! It's completely normal. I would say it's their fault, because instead of giving you a really specific knowledge and skills that makes it work for the rest of your life, they want you to go back and buy the next diet too...
