Calorie restrictive, high carb diets have a very high rate of failure. Willpower is not enough.
Yes, you can suffer through it for a month or two or three.
Eventually you tire of being always hungry. Are you going to starve yourself for the rest of your life?
So what to do?
Low carb, high fat, moderate protein. Eat this way and you will lose weight, mantain muscle, and most importantly, not be hungry. It is sustainable.
I guess it all depends on your body type and your exercise regimen.
Yesterday I took in 2300 calories made up of 230 g carbs, 122 gms fat and 75 grams protein. This is typical- I range daily from 2000-2300 while dieting. I don't feel hungry and actually yesterday i kind of felt stuffed.
I have done the low carb deal and it is useless. I drag ass all day and I feel terrible. I even get kidney stones. The longest I ever did low carb was for 1 year- and it doesn't get better. I bicycle a lot and can definitely see a performance drop on low carb. I measure my performance in watts and it is easy to see a 30% drop on low carb. Why would anyone willingly do that?
I currently weigh 203 pounds at 5'9" and am shooting to get down to about 190, if that. I notice that on a high carb but calorie limited diet I actually get leaner and yet maintain muscle mass and strength. On low carb I lose muscle like crazy and look stringy.
The single biggest thing I have discovered about diet is that overtraining - going too hard for too long or too often- causes a huge jump in hunger and yet I get weaker. I am sure this is related to cortisol levels. I purposely keep those levels down by concentrating on heart rate training.
I track my blood pressure daily (usually 120/80), resting pulse on waking (55+/-5 bpm) and Sp02 96-99%
My goals next year are the Master National Cycling Championships in the criterium (high speed, flat races) and I need a fast sprint and a very high average wattage for an hour. This diet lets me do that while slowly leaning out.
