The reason you saw weigh increase is from diet switch to carbs especially with the most potent nutrient partioning stack out tere today.
I've always told customers that there's an initial 3-5 lbs gain. But this subsides. And if you don't drop that weight it'll come off in inches somewhere else.
I'm actually surprised you lost what you did considering your low cals and huge caloric needs. But that's a different topic.
Happy to see the weight come off. If you look at pharmaceuticals. They look for a 5-10% decrease in weight over 1 year to be deemed applicable to weightloss.
This stack definitetlu provides that and more after 3-4 months.
