Oh yes, I eat sugar on occasion, too, but for me I lose the best and am the strongest when my daily eating is very clean. Then I can have a special event or day where I just don't have to worry about sugar or junk, because it will correct the next week. The more infrequent I make those days, the better control of them and my body I seem to have

. I just came back from a weekend trip that involved pizza and icecream. It was loads of fun, including the food. And now I'm back to my normal clean diet and the weekend weight is coming off very nicely, indeed
You absolutely must find what works for you. I switched up my thoughts on food and nutrition AFTER almost three years of calorie counting. I still calorie count, but cutting out the grains and sugar has made me lose better, with more energy, and less hunger. I wouldn't have done it if I didn't need to, but now I wouldn't go back. That's my body, one that has been fat for years and has inflammation issues to manage. Yours is different, and thus your plan needs to be accordingly different, too!
If you're doing a lot of lifting (I work out moderately five days a week with strength and flexibility training, so I do take in slightly more protein, too) upping your fat and protein ratios a bit could be excellent. But if you're interested in maximizing your health and getting into the 'sweet spot' with various nutrients for your body's needs, I have to give a shout out to "The Perfect Health Diet". Great stuff for maximizing nutrition.
