Clothing fit is certainly likely to be a much more useful measure. I prefer bodyfat measurements, using the cheap Accu-Measure skin fold calipers.
Most of us need to have a suitable eating plan for our lifestyle. An intense gym workout can increase our appetite. I find fresh crisp crunchy raw vegetables really great, with grilled fish, chicken breast or tuna very satisfying for that increased appetite. More carbohydrates only earlier in the day. I have five or six small meals rather than 3 large meals. That way I avoid feeling hungry.
