Could not agree more!!!
I know, I know, you see me post my anti-cardio-for-fat-loss pretty consistently.
Well, I'm going to keep doing it until it clicks and especially for you with a colourful dieting history, prior comp prep background, peri/menopausal season, or general weight-loss resistance as you've gotten older (45ish).
How about we look at a neat little study on menopausal women all doing marathon-type training.
So these women were divided into 3 different groups. They were instructed to not alter their food intake and to remain consistent to how they were eating prior to the study as much as they could.
Group 1 - 30 minutes of jogging 5x/week.
Group 2 - 45 minutes of jogging 5/week.
Group 3 - 60 minutes of jogging 5/week.
These women were followed for several months.
So how effective was all of this exercise at weight loss? This is quite a bit of consistent cardio over the course of several months wouldn't you agree?
Results?
25% of these women lost weight, although it was very modest. 50% of the women lost no weight at all. All of this cardio, and nada! The remaining 25% actually gained weight!!
30, 45, or 60 minutes 5x/week and 75% of these women lost no weight.
The 25% would have been better off doing nothing!
This is really the metabolic compensation system kicking in. This is when the metabolism realizes a lot of energy is going out to exercise, reacts in a 'cut back' fashion and you unconsciously wind up seeing is less NEAT (overall daily movement) and burning less calories for other activities (conservation/adaptation).
More cardio also increases hunger signals as well so these gainers probably had a combo of less overall daily movement, despite the hour of running, more hunger and cravings and probably less dietary consistency, more calorie consumption (probably at night) and voila, weight gain.
The compensation system wants to preserve expenditure and constrain metabolic output and increase hunger. It'll will increase motivation for food.
In bodies already tipped towards the sympathetic (stressed) side of the nervous system (age, menopause, dieting/yo-yo history), all this cardio did was add more stress, more cortisol and more of an energy-conservation message over time.
These effects are unfortunately all more pronounced in females as the female metabolism is more sensitive than your average males.
The gym is not for burning calories! Relying on cardio for fat loss is just a waste of time. It should be seen at best as supplementary and carefully programmed.
