Why Not to Follow Fad or Crash Diets ?

There are hundreds of fad diets on the market today . The problem with most fad diets is that they limit consumption of a certain macronutrient like protein, carbs, or fat, For example, with any of the low-carb diets , they severely limit your consumption of important carbohydrate sources. You may experience initial weight loss with these diets, But I strongly suggest not to follow such diets,because they will lower your RMR and put you at 

risk of regaining weight faster .

One of the first reasons people experience a quick weight loss with a low carb diet is because they  lose water weight by depleting their muscle glycogen stores. A significant quantity of water is also held in the muscle cells of the body along with the glycogen. So going on a low carb diet and depleting your glycogen stores will result in a weight loss initially .And you loose your muscle in the process as well.

Another one of the reasons that a low carb diet can cause people to lose weight is that they maintain lower blood sugar levels and lower insulin levels, and therefore can lose fat easier since high insulin levels promote fat storage and make it harder to burn fat.

However, there are ways to still eat your carbohydrates in moderation while still maintaining reasonable blood sugar and insulin levels to allow fat burning. So please do not fall into the trap of the low carb diet. The trick here is to appear at a balance between your carb and lean protein diet . You’ll never get lean if you’re overfeeding on carbs. Including a moderate quantity of healthy carbs in your diet will help you have the energy to workout intensely and maintain good energy levels through out the day .

Another type of fad diet that has been promoted in the past and even still now  for weight loss is a low fat diet. So you are limiting one of the most important macro nutrients. People struggle to lose weight on a low fat diet .A larger quantity of refined carbohydrates in the diet will now trigger higher insulin levels, which will make you crave more carbs as your blood sugar crashes. This becomes a difficult endless cycle of craving refined carbs. This makes weight loss on a low fat diet very difficult.

Also, low fat diets affect hormonal processes in the body, which can shut down your fat loss and muscle gain efforts. Fat is also needed to satisfy your hunger.Studies indicate that in order to maintain all of the healthy metabolic processes in which your body relies on dietary fat, you should keep your total fat intake somewhere between 20-40% of your total calories. Consuming a diet containing lower than 20% fat can affect your weight loss efforts and damage your health as well. So what fats to consume and what fats not to consume ? .I will post about it in th enext chapter .
