Can I drink protein shakes instead of eating?

Replacing meals with protein shakes may help you lower your daily calories, which can help you lose weight. But in time you'll need to start eating solid food again. Eating solid food may cause excess weight to return if you don't make smart food choices.

I'm trying to lose weight. Could protein shakes help? Answer From Katherine Zeratsky, R.D., L.D. Makers of protein shakes may say that their products help lower body fat or promote weight loss. But protein shakes aren't a magic way to lose weight. Some studies find that consuming a higher than usual amount of protein in your diet may offer benefits. For example, eating or drinking products that are high in protein may help you lower body fat, keep lean muscle, feel full and lose weight. But evidence is limited. And studies often test many protein sources and not only protein shakes. Replacing meals with protein shakes may help you lower your daily calories, which can help you lose weight. But in time you'll need to start eating solid food again. Eating solid food may cause excess weight to return if you don't make smart food choices. And if you rely too much on protein shakes to replace daily meals, you'll miss out on the healthy benefits of whole foods. Since protein has calories, consuming too much can make it harder to lose weight. This can happen if you drink protein shakes along with your usual diet and you're not eating less calories or exercising. The Dietary Guidelines for Americans state that an average adult needs about 46 to 56 grams of protein a day. This amount depends on your weight and overall health. As long as you're eating a healthy diet, you likely don't need to add extra protein through protein shakes or other sources. Keep in mind that the key to losing weight is burning more calories than you consume. Choose healthy foods, such as:

Fruits

Vegetables

Whole grains such as brown rice or whole-wheat bread

Low-fat or fat-free dairy products such as milk, yogurt and cheese

Protein-rich foods such as skinless chicken breasts, eggs, fish, beans, peas, lentils, soy products, nuts and seeds And avoid eating too much food with added sugars, salt or saturated fat. Also add physical activity to your daily routine. Aim for about 30 minutes of activity, such as brisk walking, most days of the week. And do strength training of all major muscle groups at least two times a week. There is a problem with information submitted for this request.

Do you retain water weight on keto?

Many keto eaters lose a lot of water weight rapidly after beginning this diet. Without carbs to maintain your glycogen (energy) stores, your body burns through them and dumps all the water they hold. That's the “water weight” you will rapidly lose in the early days of a keto diet.

kramynina/Shutterstock Your electrolytes aren’t balanced Your dietary needs change dramatically with keto. Sodium becomes a critical nutrient, as do magnesium and potassium. “At least in the initial stages of being on the keto diet, you will urinate more,” says Carolyn Dean, MD, a naturopathic doctor, nutrition expert, and author of The Magnesium Miracle. “One of the key electrolytes lost through urination is magnesium.” She adds that it’s an energy mineral, which will help you burn fat and lose weight. Dr. Dean suggests preventing a magnesium shortage by staying well-hydrated. She also recommends adding salt and high-magnesium foods or a magnesium supplement to your day. Foods high in magnesium include almonds, spinach, avocado, and chard. Roman Pyshchyk/Shutterstock You eat the wrong vegetables A lot of veggies are carb-heavy—they can’t fit into an ultra-low-carb diet. These include potatoes of course, but also yams, corn, peas, and carrots. The best options for keto dieters include asparagus, bell peppers, Brussels sprouts, leafy greens, and zucchini. “What’s tough for many people to grasp when starting out on a ketogenic diet is that you can’t really eat a lot of [certain] vegetables,” Mancinelli says. “When you’re keeping carbs super low, you have to limit vegetables—which goes counter to everything you know about how to eat healthy and lose weight.” Dieters and healthy eaters are programmed to get vegetables at every meal in order to reach their daily plant quota. However, Mancinelli says the cumulative total can blow through your daily net carbs. “The carbs in all those vegetables add up,” she says. “A few carbs here and there with cheese, nuts, and seeds, and you can really miss the mark for ketosis.”
