The second hormone that becomes involved when you begin to lose weight is a hormone known as leptin. Leptin is a hormone that is released from the fat cells to signal to the brain about how much fat we have in storage. To our body this is kind of like the indicator on a car telling us how much fuel we have in the tank. Leptin is also a messenger that is involved with controlling your metabolic rate AND your appetite.

The blood vessels and blood are the highways that transport sugar from where it is either taken in (the stomach) or manufactured (in the liver) to the cells where it is used (muscles) or where it is stored (fat). Sugar cannot go into the cells by itself. The pancreas releases insulin into the blood, which serves as the helper, or the "key," that lets sugar into the cells for use as energy.
Creatinine is a chemical waste molecule that is generated from muscle metabolism. Creatinine is produced from creatine, a molecule of major importance for energy production in muscles. Creatinine has been found to be a fairly reliable indicator of kidney function. As the kidneys become impaired the creatinine level in the blood will rise. Normal levels of creatinine in the blood vary from gender and age of the individual.

Type 2 diabetes, which is often diagnosed when a person has an A1C of at least 7 on two separate occasions, can lead to potentially serious issues, like neuropathy, or nerve damage; vision problems; an increased risk of heart disease; and other diabetes complications. A person’s A1C is the two- to three-month average of his or her blood sugar levels.
Because the population of the U.S. is aging, and because metabolic syndrome is more likely the older you are, the American Heart Association (AHA) has estimated that metabolic syndrome soon will become the main risk factor for cardiovascular disease, ahead of cigarette smoking. Experts also think that increasing rates of obesity are related to the increasing rates of metabolic syndrome.

Blood pressure rises and falls during the day depending on a person's level of activity and physical and emotional stress. Largely controlled by the autonomic nervous system (the part of the nervous system that controls involuntary actions), BP is also affected by several different hormones, including angiotensin II, aldosterone and catecholamines.
A 2018 study suggested that three types should be abandoned as too simplistic.[57] It classified diabetes into five subgroups, with what is typically described as type 1 and autoimmune late-onset diabetes categorized as one group, whereas type 2 encompasses four categories. This is hoped to improve diabetes treatment by tailoring it more specifically to the subgroups.[58]

Especially severe cases of hypertension, or hypertensive crises, are defined as a BP of more than 180/120 mm Hg and may be further categorized as hypertensive emergencies or urgencies. Hypertensive emergencies are characterized by evidence of impending or progressive target organ dysfunction, whereas hypertensive urgencies are those situations without progressive target organ dysfunction.

Researchers assigned overweight subjects to three groups: diet-only, diet plus aerobics, diet plus aerobics plus weights. The diet group lost 14.6 pounds of fat in 12 weeks. The aerobic group lost only one more pound than the diet group. Their training was three times a week starting at 30 minutes and progressing to 50 minutes over the 12 weeks. Nothing special. But the weight training group lost over 21 pounds of fat. That's 44% and 35% more than diet and cardio-only groups respectively. The addition of aerobic training didn't result in significant fat loss over dieting alone. Thirty-six sessions of up to 50 minutes is a lot of work for one additional pound of fat loss. But the addition of resistance training greatly accelerated fat loss results.

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]
