i think thats a bit exesive, if you want to loose bf i would replace more than half your hiit trainning with a solid
workout program so you can build mucle because muscle will burn calories, biger muscles means you burn more calories, diet will play a huge role as well try omega 3 and 6
essential fatty acids and keep colestoral and trans fat levels low in your diet low. that way your not going to end up a twig when ur finished don't also don't starv your self thinking that its going to help because your only slowing down your metabolism to a crawl wich mean went you decide to eat a normal amount again your going to gain fat, in the long run diets like these are not healthy and with evenually burn out your metabolism. good luck.
