- A UK man transformed his physique by following a calorie deficit and protein goal.
- He measured portion sizes instead of guessing to help burn fat for better muscle definition.
- To get enough daily protein, he started eating more fish and eggs and snacking on chickpeas.
A 41-year-old man said learning two simple diet tips helped him build a more muscular, lean physique in less than a year.
Alec Knebeg, who works for a bank in London, told Business Insider that he's been going to the gym for years but didn't give much thought to his nutrition until recently.
"I had never been somebody to count calories or thought about it and how much of an impact that can have," he said.
Under the guidance of Adam Enaz, a dietitian and personal trainer specializing in men's fitness transformations, Knebeg cleaned up his diet.
Two changes to his diet made the biggest difference in his results: sticking to a calorie deficit to burn fat and hitting a protein goal each day to help his muscles recover.
Over the past eight months, Knebeg said the diet tweaks helped him get better muscle definition by burning fat while building strength and lean mass in the gym.
"Aesthetically, there's a clear difference," he said.
A calorie deficit is crucial for burning fat
It's a common misconception that losing weight, burning fat, or building muscle has to involve extreme effort, according to Enaz.
"People have this idea that to get fit, you need to run loads or eat low carb," he told Business Insider.
Changing your body is more about simple but consistent changes over time.
To lose body fat, you need to be in a calorie deficit, or burning more energy than you eat.
Knebeg said he initially set a goal of around 1,800 calories a day, which meant measuring portion sizes and being mindful of daily intake.
"Before, if I was having granola, I'd just free pour and fill the whole bowl," he said. "The eyes are bigger than the belly, and it's so easy to consume far more than you realize."
To achieve his goal, he found lower-calorie versions of his staple foods, like swapping almond milk for regular.
Knebeg also made some trade-offs to continue enjoying habits that matter to him, like going to restaurants, by cutting calories elsewhere.
"If I know I am eating out for dinner that day I will reduce calories in my other meals to allow more to be used eating out," he said.
After hitting his fat loss goal, Knebeg increased his calories to 2,275 daily. This slight increase is key to building muscle while minimizing fat.
"When men are trying to gain muscle, they think they need to eat as many calories as they can. The calorie excess is not that much more," Enaz said.
A protein goal helps fuel muscle growth and stave off cravings
Knebeg's other major daily goal is to eat around 142 grams of protein.
Recent evidence suggests that an optimal amount of protein is 1.5 grams per kilogram of body weight (or 0.7 grams per pound) to maximize strength gains. The International Society of Sports Nutrition recommends between 1.4 to two grams of protein per kilogram of body weight. More protein may help reduce cravings on a diet.
Hitting that goal doesn't have to involve intensive changes like chugging raw eggs after each workout or swapping in supplements for every meal.
"There's a lot of bro science in the fitness community, particularly when it comes to men," Enaz said.
Knebeg said he included a lot more fish in his diet since it's a good source of protein and nutrients without many calories. He also ate more eggs and started snacking on roasted chickpeas, which have the bonus of being high in fiber.
Both fiber and protein can increase satiety, which can help you stay full for longer after eating.
Knebeg rounds out his diet with protein supplements for convenience when he needs a quick, lower-calorie boost to meet his goal.
"If I'm falling short on calories usually one scoop of protein shake will get me where I need to be," he said.
