This sentence uses the alternative conversational future tense. You form it with the present tense of a avea (here, am for I have) plus să and the subjunctive verb. Am să slăbesc means I am going to lose weight, and it is often preferred in casual everyday speech over the formal voi slăbi.

Why doesn't Romanian use the verb a pierde (to lose) for losing kilograms?

In English, you lose keys and you lose weight, but Romanian uses different verbs. A pierde is strictly for misplacing things or losing a game. To talk about losing weight, you must use the specific verb a slăbi (to get thinner or to lose weight).

What is the base verb for slăbesc and why does it have an -esc ending?

The infinitive is a slăbi. It belongs to the group of verbs ending in -i that add the -esc suffix in the present and subjunctive tenses. Because of this, for the first-person I, it becomes să slăbesc.

Why is the possessive word meu used with obiectivul instead of mea?

Obiectiv is a neuter noun. In the singular, neuter nouns behave exactly like masculine nouns, so it takes the masculine/neuter possessive adjective meu (my). The suffix -ul is the definite article, so obiectivul meu literally means the objective my.
