Exercise

In late 2017, one of my columns addressed whether you can determine if your joint issues are related to being active, normal aging, or diabetes. The answer was that you really couldn't determine the exact cause(s), but any or all of them may be contributors. Does it matter more if you know the underlying cause if you can figure out the best treatment?

A small pilot study investigates how modest hyperglycemia, not hyperinsulinemia, is better for people with type 1 diabetes during exercise.

Is there a difference in the effect on glucose control and metabolic health when people exercise in the morning vs. In the afternoon?

Ever since the US Diabetes Prevention Program (DPP) multicenter trial was completed nearly two decades ago, we have known that it is possible to prevent, or at least delay, prediabetes (an insulin-resistant state) from progressing into full-blown type 2 diabetes.

Does a higher percentage of vigorous physical activity as part of total exercise time confer additional benefits?

With the new year upon us and resolutions made, weight loss may be on your mind, and with it, low-carb eating is one possible way to cut back on calories. Before you decide how to go about losing weight, though, you may want to consider how cutting back on your carbohydrate intake may affect your ability to be physically active.

How well you perform (physically) when you exercise is impacted in a number of ways by the intake of macronutrients—that is, carbohydrate, fat, and protein—whether you have diabetes or not. Performance is directly affected by your calorie intake both during an activity and when you are recovering from it.

In these challenging times, if we only could get a medication that would boost our immune system and response to viruses, lower all stress associated with being in a pandemic, and treat most of the pre-existing health conditions that are associated with a higher risk of dying from COVID-19, we would all be lined up for it! Guess what? We already have something that does all these things already.

Lifestyle modifications as first-line treatment have paramount importance on the quality of life.

Protein is never a key exercise fuel, but it’s critical for other reasons. During most exercise, protein contributes less than 5 percent of the total energy, although it may rise to 10 to 15 percent during a prolonged event like a marathon or Ironman triathlon. Taking in enough dietary protein is important because dietary protein allows your muscles to be repaired after exercise and promotes the synthesis of hormones, enzymes, and other body tissues formed from amino acids, the building blocks of protein.
