Iron Deficiency Can Hinder Weight Loss Efforts, Experts Warn
Translated & summarized from Maariv by baba
Dr. Maya Rozman highlights that iron deficiency is a common overlooked factor hindering weight loss efforts by causing fatigue. While iron supplementation can reduce fatigue in deficient individuals, it's not a direct weight loss solution. Absorption of plant-based iron is enhanced by Vitamin C and inhibited by coffee, tea, and calcium. Proper diagnosis is crucial before taking iron supplements due to potential harm from overload.

- Iron deficiency can negatively impact daily function and weight loss efforts, according to Dr. Maya Rozman.
- Iron is vital for oxygen transport and energy production, with deficiency causing fatigue and weakness.
- Supplementing iron can reduce fatigue in deficient individuals, but isn't a direct weight loss treatment.
- Vitamin C enhances absorption of plant-based iron, while coffee, tea, and calcium can inhibit it.
- Proper diagnosis is essential before taking iron supplements due to risks of overload and underlying causes.
A common mistake people make when trying to lose weight is overlooking the importance of iron, according to Dr. Maya Rozman. While discussions often focus on protein, fiber, and calories, a deficiency in iron can significantly impact daily function and weight loss capabilities. Iron is crucial for red blood cells to transport oxygen and for energy production in muscle cells. A lack of iron can lead to fatigue, weakness, reduced physical endurance, and shortness of breath, even if hemoglobin levels are still normal.
Research suggests that iron supplementation can help reduce fatigue in individuals with iron deficiency, even without anemia. However, it does not consistently improve objective measures of physical ability and is not a direct weight loss treatment. The body absorbs iron from animal sources like meat, poultry, and fish more efficiently than from plant-based sources such as lentils, beans, soy, and whole grains. Absorption of plant-based iron is also heavily influenced by other foods consumed during a meal.
Combining iron-rich foods with vitamin C sources like peppers, broccoli, guava, kiwi, and strawberries can significantly enhance iron absorption. Conversely, polyphenols in coffee and tea, and phytates found in whole grains and legumes, can inhibit absorption when consumed with meals. Calcium can also interfere with iron absorption in a single meal. Individuals at higher risk for iron deficiency include women with heavy menstrual bleeding, pregnant women, those with restrictive diets, and people with digestive absorption issues.
Diagnosing iron deficiency requires more than just a hemoglobin test; a ferritin test is often needed to assess iron stores. Dr. Rozman advises against self-treating with iron supplements without a proper diagnosis, as iron overload can be harmful, and identifying the underlying cause of the deficiency is essential. While iron itself doesn't burn fat, correcting a deficiency can alleviate fatigue, making it easier to maintain an active lifestyle crucial for weight loss.
