'We are very unhealthy'- fitness coach Gachau Njoroge speaks on cost of bodybuilding

He explained that the body’s energy demands play a major role in how food affects weight and overall health.

According to Gachau, manual labourers and physically active people can consume meals rich in carbohydrates and fats, such as beans, rice, chapati, and even processed foods, without gaining excess weight because their daily activity burns off the calories efficiently.

The fitness coach noted that those who are less active, however, may experience rapid weight gain from the same diet, which underscores the importance of discipline and lifestyle management.

He addressed questions from followers who suggested he had “beef” with overweight people. Gachau clarified that his issue isn’t with individuals themselves but with the lack of control over eating habits.

“The only fat person I have an issue with is someone who isn’t doing anything about it,” he said. “We respect the people who take action and work on themselves,” he noted.

He emphasised that what people put in their mouths is a direct reflection of self-discipline, and failing to manage diet responsibly can have ripple effects on both personal health and family well-being.

Gachau also highlighted examples of people who balance diet and activity successfully, praising those who work out regularly and make conscious food choices.

He said respecting this effort is key, while ignoring discipline leads to predictable consequences in weight and fitness.

He urged people to take responsibility for their eating habits, explaining that healthy bodies come from consistent effort, not luck. He stressed that his guidance aims to educate and inspire, rather than shame, encouraging a mindset of accountability for one’s own health.

The fitness coach reiterated that he practices what he preaches, maintaining his physique while enjoying his preferred foods in moderation. “I eat what I want, and I stay in shape because I understand my body,” he said.
