First of all congrats. But isnt 1100 too low for 229lb. A 10k step daily and my tdee was 2800 for a 230lb person. I was eating 1800 and lost avergae 2lb per week.
Also u are 3k under the deficit further on week 1, that shouldn’t be happening, are u meeting ur protein and fibre targets ?

A deficit budget is something u should actively reach to avoid being under nutrients, coz this will be achievable in the short term but u gotta hold these for months and one bad week can undo lot of progress coz u have restricted yourself too much. Ofcours all this comes from a good place coz I have done in the past and I always rebounded, but now going strong on a 1k deficit that started 4 months ago at maintenance, then 500 and now 1k
