Stress and Weight Gain

"Cortisol belly" is a phrase used on social media for fat carried around the middle that people link to stress. It is not a medical diagnosis. Cortisol is a real hormone, and a genuine excess of it causes a rare condition, Cushing’s syndrome, which does change where the body stores fat. For most people who search the phrase, though, the weight around the middle is ordinary body fat, built up by the eating, drinking, sleeping and sitting patterns of a busy stretch of life.

That is good news, because ordinary body fat responds to an ordinary plan: a modest calorie deficit, strength training and enough daily movement, held for long enough.

It can, mostly indirectly. A stressful month at work tends to change the things that decide body weight: sleep gets shorter, meals get later and less planned, drinking at the end of the day goes up, and training is the first thing dropped from a full diary. None of that needs a hormone to explain it, and all of it can be planned for.

In the City the pattern is often predictable. Month-end and quarter-end, audit season and deal deadlines arrive at dates you can see. A block that puts maintenance weeks over those dates stops a hard fortnight turning into a lost month.

The NHS describes Cushing’s syndrome as a rare condition caused by too much cortisol. Its most common cause is taking high doses of steroid medicine for a long time; less often, a small non-cancerous growth in the pituitary or adrenal glands is responsible. The symptoms usually come on gradually and include more body fat on the neck, upper back, chest and tummy, with arms and legs that look thin by comparison, and a red, round face.

If that sounds like you, particularly if you take steroid medicine, see your GP before starting any training plan. A coach cannot diagnose it, and no amount of training fixes it. The same applies to rapid, unexplained weight change of any kind.

Stress eating is usually a timing and availability problem as much as a willpower one. The afternoon slump, the late meeting and the office snack table all arrive on the worst days. What helps is deciding in advance: a planned lunch with enough protein, a planned afternoon snack, and dinner that is ready or bought rather than improvised at 21:00. The high protein lunch ideas guide covers the first two.

If eating feels out of control, or food has become a source of distress, speak to your GP. Beat, the UK eating disorder charity, and the NHS both offer support, and a training block is not the right starting point.

The NHS puts being active first in its advice on reducing stress, and is careful about what it claims: exercise will not make your stress disappear, but it can reduce some of the emotional intensity you are feeling. For someone in a demanding job, the most useful session is the one that reliably happens. That is usually early in the morning, before the day’s meetings, and short enough to survive a bad week.

UNTIL Liverpool Street opens at 06:00 on weekdays. Two coached sessions a week before work is a small claim on a City diary and meets the NHS guideline for muscle-strengthening activity on at least 2 days a week.

The same way as any other fat around the middle: a modest calorie deficit held for weeks, strength training two or three times a week, more daily steps, enough sleep, and less alcohol. There is no exercise that burns fat from the stomach specifically, and no supplement or drink that lowers cortisol into a flatter stomach. Anything sold on that promise is selling the promise.

A 12 week body transformation gives that plan a start date, an end date and a measured baseline, and places the hardest weeks where your job is quietest.

Body Transformation City of London connects people in demanding City jobs with independent coaches at UNTIL Liverpool Street, 280 Bishopsgate, London EC2M 4RB, about 15 minutes on foot from Bank and 14 from Moorgate.
