I'm trying to cut down from 220lbs to 170lbs. I've been dieting for a month on 1500 calories a day and I have lost 12 lbs. The problem is that my cognitive function is much worse when I'm dieting. How can I not feel tired all the time and increase my mental performance? How do you calorie restrictors keep your cognitive abilities on your low calorie diets? I feel tired much earlier in the day than usual and I feel sleepy at 7:00PM and feel I need much more sleep than usual.
I just can't imagine going through university like this and I feel I may actually have to stop dieting before I achieve my goal of 170lbs to keep on top of my study. If there is a way to stop these side effects of calorie restriction than please do tell me!
My goals are very different from most if not all of yours. I want to keep as much muscle as possible while getting as lean as possible. I have been eating 200g of protein everyday to help prevent muscle loss while losing fat. The rest is just 700 calories of a mix of fat and carbs from whatever I want to eat to make a 1500 daily calorie total. I eat vegetables whenever I can and avoid processed food.
