According to experts, overconsuming protein may result in cardiovascular problems, kidney strain, and even digestive issues. Here are five warning signs of excessive protein intake you should not ignore. Dehydration When you consume too much protein, your kidneys work overtime to eliminate the byproducts of protein metabolism. This may lead to dehydration, making you feel unusually thirsty or causing darker-colored urine. Digestive issues High-protein diets often lack enough fiber, resulting in constipation, bloating, and stomach discomfort. Without a balance of macronutrients, gut health can be compromised. Bad breath If you're on a very high-protein, low-carb diet, your body may enter ketosis. This can lead to bad breath that resists even with good oral hygiene. Weight gain Excess protein does not always mean fat loss. When the body doesn't need the extra protein, it stores it as fat, contributing to weight gain despite a high-protein diet. Kidney strain Overconsumption of protein can put stress on the kidneys, especially for people with pre-existing kidney problems. Warning signs may include swelling in the hands, feet, or face. How much protein do you really need? As per the Indian Council of Medical Research (ICMR) guidelines, a healthy adult needs only 0.8-1 g of protein per kilogram of body weight per day. Athletes, pregnant women, and patients with special medical needs may require more, but only under the guidance of a qualified nutritionist or dietician.
