A small Feb. 20, 2017, study looked at the impact of a six-week ketogenic diet on physical fitness and body composition in 42 healthy adults. The study, published in the journal Nutrition & Metabolism, found a mildly negative impact on physical performance in terms of endurance capacity, peak power and faster exhaustion. Overall, researchers concluded, “Our findings lead us to assume that a [ketogenic diet] does not impact physical fitness in a clinically relevant manner that would impair activities of daily living and aerobic training.” The “significant” weight loss of about 4.4 pounds, on average, did not affect muscle mass or function.
Other kinesiologists think the keto diet could have dangerous effects on athletic performance, and it's tough to know what potential side effects a long-term high-fat diet might have for a healthy person, since we don't have any solid study results yet. Low-carb diets like keto can make it easy to neglect key nutrients like magnesium, calcium, and potassium found in fresh, high-carb foods like beans, bananas, and oats.
While there are probably plenty of pre-made bean and veggie soup options that just need a few minutes to heat through on the stovetop, making your own soup is really easy—and a great idea for your health. Homemade soups are much lower in sodium – about 100 milligrams or less per 2-cup serving. By contrast, 2 cups of many canned soups contain a blood-pressure-busting 1,200 milligrams or more, a worrisome amount considering that health experts recommend consuming no more than 1,500 milligrams of sodium for the entire day. This is also a great way to use up all those leftover vegetables in your crisper—pretty much anything works in this soup.
