Stop putting lemon in your water, unless it’s a couple thin slices in a gallon container, it’s breaking your fast.
Secondly, decide if it’s more painful to give up the sweet tooth or more painful to not lose the weight.
I love ice cream and fruit, but I make a point to know how many calories of those I’m eating. Fruit satisfies my candy cravings and ice cream the chocolate cravings. On days I want these things, I sacrifice in other places (which may not be the healthiest, but I take a multivitamin) so that I can enable myself the ability to have some of the bad things. For instance, to have 600-1000 calories in ice cream, on 16:8 I will typically replace a meal with it or eat less during that meal on OMAD.
I’d suggest giving that a shot to test and see if that allows you to see some progress. I’ve gone 265->210 beginning late September to as of this morning doing 16:8 to start and OMAD lately.
Do you feel a difference in the fit of your clothes? Perhaps your are loosing inches. Before I started IF I did 5 days of protein only and fasted from 12-8, which put my body into ketosis by day three. I bought the strips at Walmart which help test to see if your body is in ketosis. Then I switched to 20.4, I eat from 5-9 pretty much a meal and a snack, don’t count calories and lost 7 lbs in 2 weeks. Saturday I don’t fast and eat what I want. I have been able to put my body back into ketosis after a 20 hour fast even after my Saturday do what you want with day. I’m a 48 year old female in menopause.
Don’t fixate on the scale too much, I know it can be hard not to. Your body weight will fluctuate from day to day and a lot of it will depend on how much water your body is holding on to. Stick with it, maybe increase your cardio sessions and do them while you’re fasted, and only weigh yourself once a week. Reducing your sodium intake will also make your body hold on to less water weight
