When it comes to laboratory values, numbers like blood glucose and A1C levels are commonly checked. Less often, doctors order a test for your fasting insulin level; yet this test can help predict your risk of developing prediabetes and metabolic syndrome. Insulin plays a key role in metabolism, and high insulin levels can promote obesity, stimulate hunger, and increase the storage of fat.
Energy expenditure over the course of an MRT workout can easily approach or exceed 600 calories, depending on the routine. Better yet, excess post-exercise oxygen consumption (EPOC) increases dramatically. EPOC, often referred to as afterburn, measures the energy expended to return your body to its normal, resting state after a workout. Post-workout, your body uses an immense amount of energy to go from Mr. Huff-and-Puff back to Mr. Breathe-Normal. Considering that intense training can elevate EPOC for 38 hours or more, the total number of calories burned quickly stacks.[9]

At the end of the twelve-week study both groups lost weight, but the difference in the amount of muscle vs. fat loss was telling. The aerobic group lost 37 pounds over the course of the study. Ten of those pounds came from muscle. In contrast, the resistance-training group lost 32 pounds. None of the weight they lost came from muscle. When the resting metabolic rate of each group was calculated, the aerobic group was shown to be burning 210 fewer calories per day. The resistance-training group avoided this metabolic decline and instead was burning 63 more calories per day.

Emerging data suggest an important correlation between metabolic syndrome and risk of stroke. [58] Each of the components of metabolic syndrome has been associated with elevated stroke risk, and evidence demonstrates a relationship between the collective metabolic syndrome and risk of ischemic stroke. [59] Metabolic syndrome may also be linked to neuropathy beyond hyperglycemic mechanisms through inflammatory mediators. [60]
