Step 1 - Figure out your BMR.
Even if you sit in front of the computer all day, you have a BMR (Basal metabolic rate), which is the amount of calories you need daily to maintain your body weight. The formula is generalized as weight x 12. Notice, I said bodyweight, which includes both muscle and fat tissue. Without knowing your BMR, you won't know your cutting or bulking BMRs to be able to make proper dieting decisions.
Step 2 - Eat the appropriate number of calories for your goals.
If you are looking to get lean (cut up) you should eat about 10-15% calories below your BMR. Cutting or CBMR = (weight x 12) x 0.85 or 0.90. On the other hand, if you want to bulk up, your bulking BMR or BBMR = (weight x 18 or 20).
Step 3 - Don't change your diet midway, no yo-yo dieting.
When you've set yourself a goal, such as a 12 week cutting cycle, stick to it. Don't change diets or binge eat or jump from one goal to the other. If you keep going up and down in weight, changing diets too much, your metabolism will shift down – that's called weight cycling. Weight cycling is a way to really ruin the homeostasis in the body and never achieve your results.
Step 4 - Eat Early and Eat Late.
There is a ton of misinformation out there about eating. Eat in the AM, to get your day going and your metabolic rate humming and have a bedtime snack! Yes, you heard me right, eat before bed. According a study from Florida State University, eating protein snacks before bed boosts your metabolic rate in the morning.
