Muscle gain is a complex process that requires the right combination of training, nutrition, and recovery. There have been several key studies in recent years that provide important insights into how to optimize muscle growth through nutrition and training. In this article, we will summarize and analyze the findings from these studies.
Severe Deficit Impairs Muscle Growth Even with Adequate Protein and Training
A recent study looked at the effects of a severe calorie deficit versus maintenance calories on muscle growth and metabolic factors. The researchers recruited women, matched them for menstrual cycle phase, and controlled their training status and diets.
Key Findings
This suggests that even over a short time period, a severe deficit impairs the ability to build muscle compared to eating at maintenance, despite adequate protein and training stimuli. The deficit likely overwhelms the stimulatory effects of training and protein on muscle growth.
Moderate Surplus May Not Be Needed for Muscle Growth
Another recent study looked at the effects of a calorie surplus versus maintenance calories on muscle growth in trained men. The men were relatively strong but not elite lifters.
Key Findings
This suggests that a large calorie surplus may not be needed for building muscle in trained lifters. A modest surplus or even maintenance calories can support muscle growth when training is properly programmed.
Takeaways for Optimizing Muscle Gain
Based on these studies and experience coaching physique competitors, here are some key takeaways:
Avoid Severe Deficits
Severe calorie deficits will likely impair your ability to gain muscle, even when protein intake and training are on point. Deficits above 30% are excessive for gaining.
Small Surpluses Are Best
You likely don’t need a massive calorie surplus to gain muscle effectively. Aim for a modest surplus of 5-20% above maintenance. This minimizes unnecessary fat gain while supporting muscle growth.
Patience Is Key
Don’t expect to gain 2 pounds of muscle per week. Be prepared for slow, steady gains over months. Don’t get impatient and jack up calories. Trust the process.
Periodize Surpluses and Deficits
Alternate focused muscle building phases with fat loss phases. Don’t try to build muscle and lose fat simultaneously for too long.
What Works for You?
These are general guidelines, but individual responses vary. Find the surplus level that allows slow, lean gains for your body and stick with it.
Recent studies suggest you likely don’t need massive calorie surpluses to build muscle effectively as a trained lifter. A modest surplus combined with proper training and patience will go a long way. Avoid extremes like crash diets or 1,000+ calorie surpluses. Work with a qualified coach if you need guidance tailoring the process to your unique body and goals.
