    HIIT side effects

    November 11, 2017, 4:44 am

    hello Scott,

    I'm in cutting phase and I've done HIIT exercises for 10-15 min 6 times per week and lost almost all my muscles and lost fat and weight around 1 kg per week. After that, I've been told not do HIIT at all to maintain my muscles.

    My age:35

    Wight : 81 kg

    Hight :177cm

    Body fat : not sure but I think 25%

    Exercise period : one year

    Macros : protein: 20g, carbs: 200-250g, fat:60-70g. However, my calories intake was exactly 2400 calories.

    Could you advise,please?

    HIIT should NEVER be done more than 2-3 times a week. If you were doing HIIT 6 times per week, I am surprised you didn't suffer more damage. HIIT is extremely taxing on the central nervous system (CNS). It is also very stressful to the entire body when done correctly. This is why correctly done HIIT sessions are 10-15 minutes max. When you do HIIT 6 times a week, you not only never give your CNS a chance to recover but you also derail the muscle building process by spiking your Cortisol levels. Cortisol is the main stress hormone in the body and makes up your fight-or-flight response. When Cortisol is high, testosterone and growth hormone plummet and muscle catabolism ensues.

     

    My advice would be to continue the weight training to build back up the muscle, eat clean, and don't do more the 2 HIIT sessions a week of 10-15 minutes. Cardio alone is WAY overrated for losing weight and body fat and people do TOO much. Those who are starting off quite obese get the most benefit from regular cardio. However, the best strategy is a combination of weight training and cardio where 70% is dedicated to lifting weights and 30% to cardio. Those who are leaner and in shape and eat correctly don't need to rely on it as much or as frequently to get/stay lean. It is just a tool not way of life.

    Spot on advice from John!! You don't need HIIT 6 days a week. Doing it 2-3 times is plenty, even just twice a week with 15-20 minutes is great. You can definitely still do it, but you just need to adjust your diet to make sure you are not losing too much muscle.

     

    I assume you actually mean protein was at 200g, not 20g? Also.. did you go to the @mealplan page to do some calculations for fat loss? And is eating 2400 calories keeping you in a slight calorie deficit? If so, we just need to increase fats (and maybe protein a little bit) while reducing carbs. Let us know if those were the numbers you got from the @mealplan page ๐Ÿ˜Š

    Happy to help man! If you need more help let us know.. because you're in a cutting phase it would be a good idea to cut your carbs down to around 150g-200g and then increase your fats if you need to in order to make up any lost calories ๐Ÿ˜Š
