People feel full more quickly when taking GLP-1 medications. Often people skip meals or eat only small portions. In India, where many people already depend on carb-heavy foods like rice, wheat and potatoes, loss of appetite can further exacerbate nutrient deficiencies.

The most common deficiencies seen in the body due to the obsession with weight loss are Vitamin B12, Iron, Vitamin D, Folate and Calcium. Vitamin B12 deficiency is more common in non-vegetarian eaters. At the same time, the amount of milk and dairy products may be reduced during GLP-1 therapy. Apart from this, iron is a commonly deficient nutrient in women. Vitamin D is already low due to obesity. Whereas folate and calcium may be deficient due to less variety of food.
