Target zones: For fat loss 70-75% of maximal heart rate for 45 to 60 min is good. For endurance, without loosing muscle mass, 85-90% or more with 1-2 mins sustain, then slowing down to 60-70% resting. Alternating resting and bursting for no more than 30min total. You can, with time, increase burst time and decrease resting time as you get in better shape. 3 times a week with weight lift and increase protein.

Can eating milk chocolate decrease my risk for heart disease?

No: Dark chocolate, in moderation (1 small piece / day) appears to help lower the risk of heart and vascular disease. Milk chocolate does not have the same benefits due to the additives used to turn it into "milk" chocolate.

What diet will prevent the progression of heart disease?

1 doctor answer1 doctor weighed in
Dr. Joseph Roosth

Somewhat: Diet with modification of fat intake, coupled with exercise can help slow heart disease progression. To say it can prevent it is probably stretching things. However, there is no question that regular exercise coupled with good diet habits and a physician's guidance imo can clearly improve one's cardiac disease status. I believe considerable research exists to back up that statement.

Smoking: Smoking is one of the risk factors for heart disease and stroke, if you have other risk factors such as hypertension, diabetes, your risk of heart disease and stroke is even higher, i would suggest you see your doctor for evaluation.
