Weight gain while running calorie deficit

I started TRT at 100 mg/wk TC on 11/7. I've been gaining weight despite keeping close track of my calories and macros.
Averaging 1750 Cal/day and doing resistance training every other day (3 sets of 10 reps at 80% 1RM, at or close to failure on last set).
I'm 5'7", 147 lbs at start, now at 152.5 lbs this morning. Army % body fat calc at 18.5%, my cheap BIA scale says 19.7%. Looking in the mirror shows appearance pretty much inline with those figures, prob closer to 18.5% but not sure which is more accurate.
I expected to have to run a calorie surplus to gain weight and not clear how I am gradually continuing to increase weight while maintaining a calorie deficit. My BMR calc is 1439 cal/day, maintain weight estimate is about 2000 cal/day. So running around 250 cal per day deficit.
I tend to gain weight in the belly, but my waist circumference actually went down about 1/2 in from 34 to 33.5 in since starting. I am looking more muscular. No sign of fluid retention, ie. no ankle swelling, etc.
So how can I gain muscle and maintain a stable body fat given this set of pretty carefully monitored facts?
 
Intra-muscular water retention would explain it, as could refill of glycogen stores if you were low to start with. Also note that unless you are actually testing your metabolic rate with a device for that purpose (Breezing unit?) then you don't really know if you are in a deficit. If you want to lose fat, then doing a 16/8 feeding window and only cutting calories 3 days per week is likely a far better approach than traditional calorie reduction since such diets tend to lead to a reduction in metabolic rate. As Dr. Fung say, "the holy grail of fat loss is maintaining metabolic rate". Overall, your body is adjusting to the T so simply staying the course and letting things settle in could be a good plan. I find brief activity before or after every meal to be helpful too. For me that means a 10-20 minute bike ride twice a day unless I'm doing a full workout that day in which case I do one ride.
 
I only really look at my body fat percentage. Muscle weighs more than fat too.

1 pound of muscle weighs exactly the same as 1 pound of fat

Muscle is denser than fat, so pound-for-pound it takes up less room.

* Skeletal muscle tissue has a density of approximately 1.06 kg/L, while adipose (fat) tissue is about 0.9196 kg/L. This means 1 pound of muscle is more compact and takes up roughly 18-20% less space than 1 pound of fat.

Most will notice weight gain when starting T or in many cases struggle with it long after as androgens cause retention of sodium, chloride, water, potassium, calcium, and inorganic phosphates.

The majority of the weight gain in the early stages is due to increased ICW/ECW retention which one would piss away rapidly when stopping trt.


* ICW- intracellular water
* ECW- extracellular water



Although many tend to blame estradiol when it comes to bloat/water retention keep in mind that androgens increase sodium/water.

Androgens increase the retention of electrolytes.

As I stated previously the use of exogenous androgens will result in the retention of sodium, chloride, water, potassium, calcium, and inorganic phosphates.

Bloating/edema can be common in some and to what degree depends on many factors.

Inhibition of corticosteroid 11β-hydroxysteroid dehydrogenase enzymes plays a role.

Most of the initial increases in weight gain on T are water-related whether extra-cellular/intra-cellular.

Many men on trt can gain 5-15 lbs of water weight within the first month.

The majority of gains when first starting T are due to extra-cellular water (between the muscle and skin) which shows up as bloat/puffiness and intra-cellular water (inside the muscle cell) which will make the muscle look fuller and harder due to increased glycogen stores.

Even then once the body adjusts or measures have been taken to minimize the bloat/puffiness you are always going to hold more water when using androgens as the muscle cells will retain more water (intra-cellular).

When coming off androgens, especially high doses you are always going to be pissing out the water weight (extra/intracellular).

Part of the reason why men who abuse androgens mainly the so-called wet compounds deflate when they come off is because they are holding a shit load of excess water weight which is always going to be pissed away.

Understanding Your Hormones

Estradiol (E2)

A form of estrogen produced from testosterone. Important for bone health, mood, and libido. Too high can cause side effects; too low can affect well-being.

DHT

Dihydrotestosterone is a potent androgen derived from testosterone. Affects hair growth, prostate health, and masculinization effects.

Free Testosterone

The biologically active form of testosterone not bound to proteins. Directly available for cellular uptake and biological effects.
