Everyone is doing it. Your coworker swears by it. It was just three influencers this morning who posted about it. However, how do you feel about the fact that the diet trend that is taking over all wellness feeds is secretly sabotaging the purpose you are pursuing in the first place? The emerging literature indicates that the popularity of one of the most popular diets nowadays could be the fact that it is not speeding up your metabolism as much as many popular diets proclaim.
The Trend in Question

Extreme diets – Diets that contain much less than one thousand two hundred calories per day are the diet regimen that researchers are raising increasing concerns, particularly in light of metabolic counterproductivity, amongst most healthy adults seeking long-term, but sustainable, weight management.
Your Diet is Dumb When Compared to Your Body

When the calories are significantly lowered, then your body will switch to adaptive thermogenesis – the survival process that slows down the rate of metabolism to save energy. This is because your body is actually becoming more efficient with less, thus making it even more difficult to lose weight.
The Minnesota Starvation Study

Another historic study by the University of Minnesota in 1944 found that massive calorie deprivation decreased the metabolic rate of the people that were used in the study by about forty percent – an astronomical result that is today referred to as one of the most quoted studies in the fields of metabolism.
Younger Muscle loss worsens the situation

Extreme calorie denial results in fat being used together with the muscle tissue as energy. Burning muscle burns many more calories per pound than burning fat at rest, and as a result, directly costs you your baseline metabolic rate days off.
Hormones Get Disrupted

This is excessive constriction that inhibits the production of thyroid hormone, the main control of the metabolism rate. The evidence on this can be seen in research that appeared in the Journal of Clinical Endocrinology and proved that active thyroid hormone levels in healthy adults significantly decrease as a result of long-term calorie restriction.
Leptin Drops Dramatically

Leptin -your major satiety hormone- plummets greatly in severe calorie depletion. The low leptin levels inform your brain to slow down metabolism, your stomach is hungrier, and your fat reserves are preserved – the last thing to all weight loss plans you had in mind.
The Rebound Effect Is Real

Studies have always revealed that weight regain is high among all cases involving extreme calorie restriction. Slowed metabolism and hormonal disruption together make potent biological pressure in order to put on regained weight in no time.
What Research Suggests in Reality

A small calorie deficit (three to five hundred calories per day) that is balanced with enough protein content will not only conserve muscle mass but the metabolic rate, as well as cause slow fat burning without provoking any adaptive thermogenesis or hormonal imbalance whatsoever.
Protein: The Metabolism Guardian

Lean muscle mass is maintained in any calorie deficit by consuming sufficient protein, and the metabolic rate is effectively maintained. The studies suggest a range of zero point seven to one gram of protein intake per pound of body mass per day in order to maintain maximum protection of metabolism.
Al-Wahhabi Beats Dramatically

The most dramatic method can never be the safest in a metabolically protective manner. Regular small deficits, sufficient protein, frequent strength workouts, and getting enough sleep combine to ensure permanent fat loss without causing your body to initiate inborn defense responses, which are almost overwhelming.
