As suggested by James - Portion control and what does it mean?
Well I personally don’t believe in portion control to the effect of limiting the amount of food so that you are hungry! I do agree that you do not want to push yourself to the point of moaning and unzipping! Taste has to be a bit compromised in the way that you must not over eat items you enjoy. Control portions by having reasonable helpings of foods which are not threatening to your goals. Do have 6+ small meals per day - THAT is controlling your portions in my eyes, but do not limit yourself to less than 3 meals per day or very low calories. Metabolism needs to be fired up to burn fat, by eating every 2-3 hours you are doing exactly this which is the optimal way. Go big on dark leafy greens, large portions of this is great, fill up on that fiber and you won’t feel hungry, then the protein should be lean and will aid in appetite control so that your starchy carb does not have to be a large portion, keep this controlled to moderation. Do eat good fats in moderate portions, going too low or too high is adverse to your goals.
