Protein Shakes for Weight Loss: Why You Don’t Need Them
I’ll never forget Seth, my friend and neighbor in college, who, like many people, was lured by the clever marketing promoting protein shakes for weight loss. “Lisa, I started a diet this week!” he shared excitedly. “Check it out, I’m drinking this shake with all my meals and it’ll help me lose weight!” By adding shakes to his meals, he was on the path to gain weight, rather than lose it. I first commended him for working towards a healthier life, then gently educated him on the fact that these shakes are meant to be eaten instead of a meal rather than in addition to.
Brands that produce protein shakes for weight loss will claim that if you drink their shake, you’ll lose weight. This is both inaccurate and misleading. Losing weight is based on a calorie deficit — basically your body using more energy than it takes in. Protein shakes may be a helpful short-term tool for reducing your overall daily calorie consumption, but eventually, you’ll need to reincorporate solid food into your diet. The key is to learn which foods and lifestyle activities are sustainable and work best for you.
Why and how to use protein powder for weight loss
In an ideal world, you’d get all your protein and nutrients you need from a balanced diet. But we understand that sometimes that’s unrealistic when juggling work, family, and everything in between. When you’re struggling to meet your dietary needs through food, it may be helpful to supplement meals. For instance, if you’re still getting to grips with the ins and outs of a plant-based diet and unsure what foods contain protein, then one of the benefits of protein shakes is they will enable you to reach your recommended daily value.
Protein powder also makes sense if you’re eating breakfasts or snacks such as smoothies or cereals low in protein. The protein powder will keep your blood sugar stable and prevent cravings, hunger pangs, and dips in energy — which are saboteurs of weight loss. When shopping for protein powders, make sure to get minimally processed options with just a few ingredients.
Benefits of protein shakes with whole foods
When chosen correctly or made at home, protein shakes can increase the feeling of fullness and boost your metabolism all while maintaining muscle mass. The problem is that protein shakes for weight loss are often made from processed and inflammatory types of protein with lots of artificial additives.
Here are some dangerous chemicals to watch out for:
Heavy metals (arsenic, cadmium, lead: We’re not talking about Metallica here — heavy metals can be toxic and cause cancer when consumed in high doses.
Whey protein concentrate and caseinate: Processed and high in lactose, whey protein can lead to bloating and gastrointestinal upset.
Glucose/dextrin: These are other terms for sugar. Glucose and dextrin raise blood glucose levels which, when consumed frequently, can contribute to gastrointestinal distress and diabetes.
Artificial sweeteners (sucralose, Splenda, aspartame): These sweeteners can lead to headaches, migraines, gastric distress and even weight gain in some people.
Trans or hydrogenated fat: Vegetable oils are often used in protein shakes to lend them thickness but many times the oils used are hydrogenated, resulting in inflammation, cancer, high cholesterol, and heart disease.
Thickeners (xanthan gum): These thickeners can produce bloating and stomach discomfort in some individuals.
There are many benefits to making your own protein shakes that go beyond shielding yourself from potentially harmful chemicals. One advantage is that whole foods increase the biological value of protein, vitamins, and minerals, meaning how well you absorb nutrients. Another reason is cost. When you buy a branded shake, you’re paying for the brand. There are a wide variety of low-cost foods that’ll feed your body with all the nutrients and protein it needs.
If you still can’t get yourself to commit making a home-made protein shake, at least aim to choose store-bought options with no artificial sweeteners, minimal to no sugar, and absolutely no hydrogenated oils or ingredients you can’t pronounce.
