Anyone increase their calories for weight loss?

Summary

Can raising daily calories break a weight-loss stall while on tirzepatide after already losing 20 kg?

Most participants agree the stall means current intake now matches real expenditure, so either a modest further cut, a controlled increase to restore metabolism followed by another cut, or a dose bump are the practical options. Large deficits are viewed as likely to trigger adaptation that slows further loss. Tracking intake accurately and testing small changes over weeks are recommended over relying on calculators.

What this discussion establishesWhere people disagree

Whether metabolic adaptation can fully offset a deficit or only narrow it; whether larger deficits cause proportionally more muscle loss

Still open

Which approach (cut further, increase then cut, or raise dose) will work best for this person without new tracking data

Nothing here is advice.

Started around 120 kg last year and dropped to 100 kg on tirzepatide after six months. The scale has not moved in the last couple of months even though daily intake stayed in the 2000-2500 range with 150-200 g of protein, the same numbers that produced the earlier loss. An online calculator put BMR near 3300 because of five strength sessions, two 5 k runs, and 10 k steps daily. The idea that any deficit should produce loss makes me wonder if eating more might actually restart progress.

A 1000-1200 calorie deficit worked at first but progress stopped early in month three. Raising intake to leave only a 500-600 calorie gap let the scale keep moving, though more slowly. Keeping protein high while staying in a moderate deficit seems key, and very large deficits appear to make the body hold onto stores more tightly.

You would need to drop well below 1000 calories before metabolic adaptation could fully protect weight. Raising the dose of reta or adding cjc would probably move the scale faster.

Raised daily calories to at least 2300 after realizing previous targets were too low. Strength in the gym improved within two weeks and scale weight stayed the same while body-fat estimates looked stable or slightly better. Planning to run the higher intake for six weeks and recheck caliper measurements.

The biggest error is guessing both intake and expenditure instead of tracking them. Most people do best with a 500-700 calorie deficit; bigger gaps tend to produce stalls as the body adapts. Increasing the GLP dose will not correct poor tracking, and larger deficits also risk more muscle loss along with fat.

The claim that aggressive deficits always cost extra muscle lacks strong evidence and shows up in studies as either no difference or the opposite result. For the original question, 2000-2500 calories has likely become the new maintenance level, so further loss would require going lower. Metabolic adaptation is real and unavoidable after weight loss.

Energy needs drop with the 20 kg already lost and some adaptation may be occurring even if six months is early. Calculator estimates can be off by large margins, food tracking is rarely exact without weighing everything, and added muscle from training could mask fat loss on the scale. Raising the GLP dose remains the simplest next step if more loss is the goal.

Repeated training makes the same workout burn fewer calories over time because the body becomes more efficient at the movement.

WarmAlder51archiveApr 28

Still eating in the 2000-2500 range most days, sometimes a bit higher or lower. The activity level makes a 3300 BMR plausible, yet the scale is flat. Replies so far suggest either moving to a smaller deficit, dropping calories further, or raising the GLP dose. Raising the dose is not appealing because appetite is already controlled and protein intake might suffer.

CopperSignal27archiveApr 28

If weight has been stable for months at 2000-2500 calories then that range is the actual expenditure, regardless of any calculator. Thermodynamics still holds: sustained lower intake than expenditure produces loss. Weight change itself is the best real-world measure of energy balance outside a lab.

Maintenance calories have probably fallen because of the fat already lost. Dropping intake much below 2000 could hurt hormones and energy given the training load. A slower increase of 500-600 calories might restore metabolic rate and training quality, allowing a later cut from a higher baseline.

WarmAlder51archiveApr 28

A sedentary person of similar size would need roughly 2000 calories, yet the current intake plus heavy training still produces no loss. Occasional days at 1000-1500 calories leave me too tired to train the next day. Testing a strict 2000-calorie week against a 3000-calorie week might clarify what is actually happening.

CopperSignal27archiveApr 28

The idea that weight stability directly reveals true expenditure makes sense. Earlier experiments with adding long daily walks produced no detectable change in loss rate despite constant intake. Short controlled tests at 2000 versus 3000 calories for a week or two would give clearer data.

GreenMeadow54archiveApr 28

Daily intake still needs to be tracked consistently rather than estimated. Eating the same number of calories every day and then slowly adding until the scale moves is the only way to learn true maintenance. Glycogen refill can cause a small temporary jump when calories rise after a deficit.

Two thousand to twenty-five hundred calories holding weight steady for months is the best evidence of current maintenance. Calculators are overestimating. Metabolic adaptation slows things but does not cancel a real deficit. Raising calories does not directly cause fat loss except when it first restores a suppressed metabolic rate.

Hormonal effects are visible when people feel constantly cold and low-energy under heavy restriction. GLP compounds can produce more loss than calorie intake alone would predict, showing that CICO estimates are often poor in real conditions even though energy balance itself is never violated.

Adaptation narrows the gap between intake and expenditure but does not erase it. The GLP example simply shows that expenditure can differ from simple estimates. In practice the stable weight at 2000-2500 calories already tells us that range is current maintenance.

Calorie math works best with fixed meals or fasting; variable food choices add too many unknowns for day-to-day prediction. The only firm conclusion from months of stable weight is that intake currently matches expenditure. Cutting the same foods slightly would likely restart loss, but that is obvious.

WryQuill92archiveApr 28

Katch-McArdle gives a reasonable BMR once body-fat percentage is estimated with calipers. Tracking is done with a basic app and scale only when needed. Protein and fat stay high while carbs usually land between 40-60 g.

Food composition and hormones affect expenditure, yet body weight over time remains the clearest feedback available. When weight has been flat for months the current intake is matching real expenditure. Practical choices stay the same: eat less, move more, or adjust medication to create a deficit.

People blame metabolic slowdown for stalls when calculators promised a certain maintenance level that no longer matches reality after weight loss.
