5 Nutrient Deficiencies You May Develop on GLP-1s

While GLP-1 medications like Ozempic, Wegovy, and Zepbound can be effective for weight loss, they may also cause nutrient deficiencies. These medications work by reducing appetite and increasing feelings of fullness, which can lead to a decrease in overall calorie intake. However, if not enough attention is paid to nutrition, deficiencies in essential vitamins and minerals can develop.

Protein Deficiency

Not consuming enough protein can lead to loss of lean body mass, weakness, edema, hair loss, and skin changes. The recommended daily intake of protein varies based on age, sex, exercise frequency, and health status. According to the Dietary Guidelines for Americans, most adults should consume around 50 grams of protein per day. For individuals living with obesity who are on treatment to lose weight, their doctor may recommend as much as 60 to 75 g/day of protein. To avoid protein deficiency, focus on consuming protein-rich foods such as eggs, nuts, chicken breast, cottage cheese, Greek yogurt, milk, lentils, and tofu.

Vitamin D Deficiency

Vitamin D is essential for maintaining strong bones and preventing diseases such as osteoporosis. Adults ages 19 to 70 years should aim to consume 600 IU of vitamin D daily. Deficiencies in vitamin D can cause muscle pain, muscle weakness, fatigue, bone pain, and tingling sensations in the hands and feet. Vitamin D-rich foods include fatty fish, beef liver, egg yolks, cheese, and fortified milk. For individuals following a vegan diet, fortified cereals and meat substitutes can be a helpful alternative.

Calcium Deficiency

Calcium is crucial for maintaining strong bones and teeth. Adults need 1,000mg to 1,200mg of calcium daily. Deficiencies in calcium can lead to muscle cramps, numbness, and tingling sensations in the fingers and toes. Calcium-rich foods include milk, yogurt, cheese, and leafy greens. For individuals avoiding dairy products, calcium-fortified cereals, soymilk, and tofu can provide sufficient calcium.

Vitamin B12 Deficiency

Vitamin B12 plays a vital role in maintaining healthy blood cells and nerve function. Deficiencies in vitamin B12 can cause fatigue, headaches, pale or yellow skin, and difficulty concentrating. Recommended daily intake of vitamin B12 for adults is 2.4 mcg. Natural sources of vitamin B12 include animal products such as meat, fish, poultry, eggs, and dairy. For individuals following a vegan diet, fortified plant-based milk, cereals, and meat substitutes can provide adequate vitamin B12.

Iron Deficiency

Iron is essential for healthy red blood cells. Adults need 8mg of iron daily, with increased needs for individuals with heavy menstrual periods. Deficiencies in iron can cause tiredness, weakness, shortness of breath, pale or yellow skin, and brittle nails. Iron-rich foods include lean beef and poultry, legumes, whole grains, fortified cereals, and spinach. Pairing iron-rich foods with vitamin C-rich foods, such as bell peppers, strawberries, and citrus fruits, can enhance iron absorption.

Managing Nutrient Deficiencies

While on GLP-1 medications, it’s essential to prioritize nutrition to minimize the risk of nutrient deficiencies. Consider the following tips:

• Think about what you drink: Choose beverages that provide hydration, nutrition, and calories, such as protein-rich smoothies and Greek yogurt.
• Adjust your food intake: When starting GLP-1 medication, eating soft, blended, or liquid meals can help manage symptoms. Consider overnight oats, smoothies, and protein shakes as convenient and nutritious options.
• Avoid empty calories: Steer clear of sugary beverages, sweets, alcohol, and ultra-processed snack foods, which provide low nutritional value and can replace nutrient-dense foods.
• Take a multivitamin: Consult with your doctor about taking a multivitamin or supplemental vitamin D and iron to ensure adequate nutrition.
• Self-monitor your habits: Keep track of your diet, hydration, and exercise habits to ensure a balanced lifestyle.

Conclusion

GLP-1 medications can be an effective way to manage weight loss, but it’s crucial to pay attention to nutrition to minimize the risk of nutrient deficiencies. By prioritizing protein-rich foods, calcium-fortified beverages, vitamin D-rich foods, vitamin B12-rich foods, and iron-rich foods, you can maintain optimal nutrition and minimize the risk of deficiencies. If you experience side effects or concerns, consult with your doctor and a registered dietitian to develop a personalized nutrition plan.
