Very Low Calorie/Carb Diet + HIIT

I have a client that is partaking in a Biggest Loser type of contest.

She’s in the lead right now with 3.5 weeks left.
She’s gone from 150 to 134 lbs but has stalled for the past 2 weeks.
She’s also dropped 10% bodyfat, so obviously great results after 8.5 weeks.

She wants to win, and so do I.

For the final stage we’re going to have her around 1350 cals/day, with a re-feed once a week at 2,000 calories.

She’s supplementing with 1.5 servings of Flameout, ZMA, 4 pills of HOT-ROX, and I just decided to pull her off 1/2 serving of Surge.

My question is this.

Is it advisable to still perform HIIT while on a Very Low Calorie/Carb Diet (she works out 6 x week for a total of about 6-7 hrs)

Doing the math in the PN book I have her at 335 cals/meal x 4 with 28g protein, 10g carb, 20someodd g/fat.

Should I have her only do low-moderate steady state cardio and no HIIT?

She’s on a 4x week RT program right now, and I’m probably going to cut that down to 3x week for the remainder of the program.

thanks for any help

Well, I’m no trainer, but I tend to lose muscle when I do HIIT, especially when carbs are low. However, I assume the dumb contest measures only scale weight, so it wouldn’t matter in this case.

All I know is what happens with me. If fat loss stalls for 2 weeks, metabolism has dropped, the body’s fighting to keep the remaining fat, and muscle loss is imminent (for me). I increase my calories and carbs substantially, and then drop a bunch more fat. And I’m surprised every time it happens.

But that’s just me.

Jehova, in my experience with HIIT, it can be real hell on a low carb diet. I’ve tried it before on low, moderate, and high carb diets(<75g, ~125-150g, 200g carbs respectively) and I feel like absolute shit when doing it on low carb. It just took too much out of me. Granted, this was also on top of intense lifting 4-5x a week. You can give it a shot, but maybe it would be more efficient to mix up HIIT and steady state together.

body fat is a concern as well for the contest

yeah, I’m thinking low-intensity steady state to preserve muscle mass.

I’m on a low-carbohydrate diet at the moment, and I find that a series of Tabata bike sprints isn’t too overwhelming. I just do 3 minute warm-up, then do a set of Tabata sprints followed by 2 minutes of easy peddling. I repeat for a total of three 4-minute intervals, followed by a cool down.

If your client can handle HIIT, I don’t see why not. If she has stalled out on 6-7 hours of exercise per week, it may be too much. If she wants to maintain that amount of effort, I’d make sure she was on a cortisol-regulating supplement.

I’m just some guy on a forum, though.

LOL, eggers, your opinion is as valued as anyone else’s. I don’t see why you need to degrade yourself to just “some guy”. What works for you may work for others as well :).
