Mastering Maintenance: The Diet After the Diet

Losing weight and keeping it off are two different skills, though are built from the same plan. Losing weight is not as simple as it is sold, however keeping the weight off is arguably a more important piece of the body composition puzzle. For many people they feel they are either strictly on a diet, or so far off a diet it isn’t even funny. They haven’t figured out how to eat with maintenance in mind without the burden of fear that it will lead to weight gain. This post outlines some key habits and behaviours that give you confidence once the fat loss phase is over.

The first consideration is that your lowest weight at the end of a diet is often not the weight your body will comfortably sit at while you live a normal, busy life. And maintenance is not a single number. From a caloric perspective, your calories sit roughly 150 to 200 either side of your maintenance number; it is a band you move around inside. Similarly, your weight can swing 1-2 kg on any given day of the week, from water, salt, food volume and your cycle. A stable week holds a range of about 1 to 1.5 kg. You steer the weekly average. The daily number is noise.

Your body will push back

After weight loss your body defends on three fronts. Hunger hormones rise and fullness signals fall, so you are hungrier than you were before you lost weight. You become more insulin sensitive, which is good for your health, but insulin is a storage hormone and recently shrunken fat cells are primed to soak energy back up. And you burn slightly less calories than someone who has always been your weight.

The mindset that makes or breaks it

Someone who sees themselves as a dieter will chase a number on the scale and an end date. Someone who sees themselves as a person who values health, fitness, independence and resilience will view their food and exercise as ‘this is just what I do now.’ “I’m on a diet” becomes “I eat this way.” This shift in identity is a fundamental pillar of someone who successfully loses weight and keeps it off.

The second is flexibility. All-or-nothing thinking, good foods and bad foods, one off meal writing off the whole day, is a strong predictor of regain. Rigid and flexible dieters lose similar amounts of weight. The flexible ones keep it off. One off meal out of the 21 you eat in a week is neither here nor there. It’s what you do next that makes the difference.

Movement takes the wheel

During weight loss, the caloric deficit caused by the diet does the driving. In maintenance that flips, because movement offsets the lower caloric burn required to move a smaller body. Treat 8,000 steps as your floor. Research shows long-term maintainers average 12,000 plus, mostly walking. Add two to three resistance sessions a week to protect your muscle. Aerobic exercise is important too.

What makes this survivable is keeping three versions of your week: an A-game for your best weeks, a B-game as your reliable normal, and a C-game for the weeks where life has just gotten on top of you, which is one session, a daily walk and 5,000 steps. On a hard week you drop to C, not to zero, because the person who drops to zero has to restart from zero.

Monitor four things, not just the scale

Diet: roughly what you are eating, logged three to five days a month or a food journal to write down what you eat. Body: weight as a seven-day average (even 4 times across a week), plus a monthly waist measurement. Habits: did you hit your non-negotiables? Habits drift before the scale does. Training: are you getting stronger? Faster? Fitter? These training metrics are arguably most important when you’re maintaining your weight.

Get into the habit of checking in daily, weekly and monthly on these things. Five minutes daily, ten minutes weekly, thirty minutes monthly, which is where you adjust. If your four-week average has trended up more than 1.5 to 2 kg with no clear cause, pull 100 to 150 calories a day for two weeks. Drifted down, add the same. The game is catching drift at 2 kg, when it is easy, instead of at 8 kg.

Real life, and the bounce-back

Eating out or being on vacation is not the problem. Having no framework is. Do not starve throughout the day to save up calories, because you will arrive ravenous and overshoot. Eat protein-forward all day, build the plate at the table around protein and stop before you are stuffed. When you are on holiday, pick an eating structure that makes sense for your schedule: drop the snacks, or eat two meals plus a protein snack, or two on-track meals and one relaxed. You’ll likely be active on holiday even in the absence of structured workouts, as many of us are not stuck behind a desk for most of the day.

When it goes off track, and it will, it’s good to have a bounce-back plan. Weigh in within three days of being back and treat whatever you see as information. Return to your C-game and your non-negotiables. No cleanse, no fast, no penance workout, because adding restriction on top of a slip is how a short slip becomes a long one. Expect 1 to 3 kg of water to drop in the first week, and only adjust if you are still up after a fortnight.

None of this asks for perfection. It asks for attention, and a framework you can put in place and run when life isn’t perfect (as life often is not!).
