So, if, after seven to ten days, your weight hasn’t gone up despite pushing yourself hard in your workouts, you’re just not eating enough. Increase your daily intake by 100 calories (by adding more carbs, preferably) and reassess over the next seven to ten days. If this doesn’t result in weight gain, increase again and repeat the process until you’re gaining weight at a rate of about 0.5 to 1 pound per week.
