NP so if I'm 48 and when I exercise my heart rate stays around 105-115 is that "good enough" to burn any fat?

You heart rate doesn't matter as far as metabolizing fat.

What matters is your carb intake. Eat excessive carbs, then your body uses carbs for fuel and your body reserves most of your fat deposits.

Eat less carbs to none, and you start using up that fat stored on you.

Heart rate doesn't matter. You could walk 10 miles at a slow pace or jog it at a fast pace, the calories used is the same.

I don’t want to be rude, but this is fundamentally wrong. Though it may sort of be accurate for an average person.

You don’t think pro tour cyclists are extremely efficient at oxidizing fat? Have you considered their heart rate profile? Those boys are taking in 120g / hour. That’s not matching their output and they are not bottom out their glycogen stores during a stage.

How about pro triathletes during full distance Ironman races? Those are the extremes. Even an average age cyclist is oxidizing fat if they ride their bike for 3+ hours, even with carb intake.

Well most posters here are not pro athletes, but slightly overweight middle aged women. So this theory is true but doesn’t matter too much, just be more active than a rock, and eat less will do.

Eating less is very hard for many people. For me, vigorous exercise suppresses my appetite. It also makes ultraprocessed and sugary foods unpalatable. And it improves my mental health.

And I think there is too much hype around low carb diets. It is extremely difficult to get enough fiber if you are also minimizing your carbs to the lowest amount possible. Fiber is really important. A bowl of oatmeal with apple and peanut butter in the morning is good for you!

While eating less / monitor fiber intake is hard, these things are good for our health.
While working until 9pm eating chips is easy, it’s good for billionaires CEOs and big food company, not us.
I think it’s more important to prioritize the only life you have, not bezo’s networth.

I agree with you! And I think exercise is important and can support weight loss.
