Studies indicate that prolonged and severe calorie restriction can decrease your body's metabolic rate significantly, a process known as metabolic adaptation. But what happens when you eat below your RMR, the absolute minimum calories needed for basic functions? The effects can be far-reaching and detrimental to your health, impacting everything from your energy levels to your long-term metabolic health.

According to the SURMOUNT trials, while Mounjaro effectively reduces appetite, around 5-10% of users report struggling to eat enough. Neglecting your nutritional needs while taking this medication can lead to serious health complications and sabotage your long-term weight loss goals.

According to a 2024 study in *Redox Biology*, athletes who intentionally underfueled saw a significant drop in performance and an increase in systemic stress hormones. This demonstrates that if you train hard without eating, you are actively undermining your health and fitness goals, triggering a cascade of negative physiological and psychological effects.

According to one meta-analysis, up to 45 percent of athletes experience low energy availability, or 'undereating', highlighting a prevalent issue beyond just elite sports. Far from optimizing results, working out without adequate fuel can have serious repercussions on your body and fitness goals.

Scientific studies show that while challenging, it is possible for specific groups of people to build muscle even in a caloric deficit. However, attempting to build muscle without eating enough comes with significant hurdles and risks that often lead to muscle loss instead of growth. This article explores the precise conditions where this is feasible and why a calorie surplus is the optimal path for most individuals seeking significant muscle hypertrophy.

According to research published in the *Journal of the American Medical Association*, severe calorie restriction often leads to a decrease in basal metabolic rate, signaling a critical metabolic change. The misconception that bigger deficits lead to faster results can actually backfire, causing unwanted side effects that hinder progress and harm overall health.

The Dietary Guidelines for Americans recommend 1,600 to 2,000 daily calories for adult females and 2,000 to 2,400 for males to maintain their weight. A 1500-calorie intake can create a calorie deficit, but whether it is a safe and sustainable approach depends on individual factors.

According to a 2019 study, a sustained negative energy balance can impact the body's metabolism, hormone production, and mental well-being. This state, where the body expends more calories than it consumes, is not just a tool for weight loss; it carries a range of serious consequences that affect nearly every system in the body, especially if prolonged.

Clinical trials show that between 5% and 11% of patients taking Mounjaro for type 2 diabetes reported decreased appetite as a side effect. This reduction in hunger is an intended part of how the medication works to aid in blood sugar control and weight management.

According to the Dietary Guidelines for Americans, a sedentary 16-year-old female might need around 1800 calories, but this can be insufficient for many. Whether 1800 calories is enough for a 16 year old depends heavily on individual factors like sex, activity level, and growth stage, which can significantly alter their daily energy requirements.
