Two people at 5'7" and 136 lbs can look very different depending on body fat percentage. Explore what each level looks like:
At 5'7", a weight below 118 lbs puts you in the underweight BMI category (below 18.5). Being underweight can lead to nutrient deficiencies, weakened immunity, bone loss, and hormonal issues. If you are underweight, consult a healthcare provider and focus on nutrient-dense foods with adequate protein.
Yes. People with larger bone structures (wider wrists, broader shoulders) naturally weigh more at the same height and body fat. The formulas above provide averages. If you have a large frame, you may be healthy at the upper end of the range (159 lbs). Small-framed individuals may be healthy at the lower end (118 lbs).
If you are above the healthy range, create a moderate calorie deficit of 500 cal/day for ~1 lb/week loss. If below, add a 300-500 calorie surplus. In both cases, prioritize protein (0.8-1g per lb body weight) and resistance training.
